DISASTER NURSING AND
EMERGENCY PREPAREDNESS
ICN Disaster Framework of Nursing
Competencies 2009
“Nurses, as the largest group of committed health
personnel, often working in difficult situations with
limited resources, play vital roles when disasters
strike, serving as first responders, triage officers
and care providers, coordinators of care and
services, providers of information or education,
and counsellors. However, health systems and
health care delivery in disaster situations are only
successful when nurses have the fundamental
disaster competencies or abilities to rapidly and
effectively respond.
The International Council of Nurses and the
World Health Organization, in support of Member
States and nurses, recognize the urgent need for
acceleration of efforts to build capacities of
nurses at all levels to safeguard populations, limit
injuries and deaths, and maintain health system
functioning and community well-being, in the
midst of continued health threats and disasters.”
(ICN & WHO)
CORE COMPETENCIES
The Steering Committee
identified three levels of nurses needing
competency in disaster nursing at
increasing levels of complexity. Bear in
mind that for any level or any one
competency, the nurse begins as a
novice, should move toward proficiency
as defined by national or institutional
standards, and may become an expert.
Expertise within any one level does not
confer automatic ability to perform
competencies at a higher level. The three levels
of nurses defined for use in Version 2.0
FROM NOVICE TO EXPERT
Nurses develop skills and an understanding of
patient care over time from a combination of a
strong educational foundation and personal
experiences. - Patricia Benner (1995)
• Novice
• Advance Beginner
• Competent
• Proficient
• Expert
APPLICATION OF THE COMPETENCIES
Effective nursing practice during any disaster
requires clinical competency and the
application of utilitarian principles (doing the
greatest good for the greatest number with the
least amount of harm).
Jeremy Bentham (1748-1832)
He was concerned with social and legal reform
and he wanted to develop an ethical theory
which established whether something was good
or bad according to its benefit for the majority of
people. He called this the principle of utility.
UTILITY = the usefulness of the results of
actions.
DUTY TO ACT
A legal duty requiring a party to take necessary
action to prevent harm to another person or to
the general public.
Impetus for the Development of the
Framework of Disaster Nursing
Competencies
“Nurses with their technical skills and
knowledge of epidemiology, physiology,
pharmacology, cultural-familial structures, and
psychosocial issues can assist in disaster
preparedness programmes, as well as during
disasters. Nurses, as team members, can play
a strategic role cooperating with health and
social disciplines, government bodies,
community groups, and non-governmental
agencies, including humanitarian
organizations.” - ICN (2006)
ADAPTATION
“The goal of nursing is] the promotion of
adaptation for individuals and groups in each of
the four adaptive modes, thus contributing to
health, quality of life, and dying with dignity.” -
Sr. Callista Roy (1970)
Disaster Nursing
Disaster nursing is the adaptation of
professional nursing knowledge, skills, and
attitude in recognizing and meeting the physical
and emotional needs of disaster victims.
Competence
• knowledge, understanding and judgment;
• a range of skills─cognitive, technical or
psychomotor and interpersonal; and
• a range of personal attributes and attitudes”
• “a level of performance demonstrating the
effective application of knowledge, skill and
judgment” - ICN (1997)
Competencies
• Nurses must be able to work internationally, in
a variety of settings with nurses and health care
providers from all parts of the world. To assure
a global nursing workforce ready to respond in
the event of a disaster, competencies are
essential.
NEED FOR COMPETENCIES
• facilitate deployment of nurses globally;
• create consistency in the care given;
• facilitate communication;

CYCLE OF DISASTER MANAGEMENT

ROLES OF THE NURSE

Disaster Management Roles of Nurses

1. Community Assessment

2. Community Diagnosis of Disaster Threat

3. Community Disaster Planning

4. Implement Disaster Plan

5. Evaluate Effectiveness of the Disaster Plan

Community Assessment

1. Is there a current disaster plan in place?

2. Previous diaster experiences?

3. How is the local terrain condusive to

disaster?

4. What are the local industry?

5. What personnel are available for disaster

interventions?

6. What local agencies and organization are

available?

MITIGATION/PREVENTION

✓ perform community needs assessments to

determine the pre-existing prevalence of

disease, the susceptibility of health facilities

and identification of vulnerable populations,

such as those with chronic disease, mental

health problems, or disability

✓ collaborates in developing plans for

alternative housing and other interventions

designed to reduce the vulnerability of these

populations.

✓ Participation in risk reduction activities in

health care facilities to create safe and

sustainable environments for care or identifying

alternative sites for care following a disaster is

another activity that requires the expertise of

the nurse. Working in partnership with other

health care providers and community leaders,

the nurse helps to plan for the evacuation of

health facilities and relocation of patients as

required.

✓ Helping to shape public policy that will

decrease the consequences or potential effects

of a disaster is an important role because of the

nurse’s knowledge of the community and the

areas of vulnerability. Working with policy-

makers to identify hazards, the risk such

hazards pose to the population, and health

infrastructure to develop solutions that reduce

the risk are all part of nursing’s role. Ongoing

community education related to identification

and elimination of health and safety risks in the

home or community is another area where

nurses bring expertise.

PREPAREDNESS

✓ creation of policy related to response and

recovery requires nursing input

✓ provide assessments of community needs

and resources related to health and medical

care which contribute to the planning activities.

✓ plan activities such as communication,

coordination and collaboration, equipment and

supply needs, training, sheltering, first aid

stations, and emergency transport all require

nursing expertise

✓ develop and provide training to other nurses

and health professionals, as well as the

community

✓ capacity-building through recruitment and

maintenance of a ready disaster nursing

workforce is also part of nursing’s role

✓ involve in leadership roles, planning,

participating in, and evaluation of readiness

exercises to assure that the community, and

the nursing workforce itself, is prepared in the

time of an emergency or disaster

✓ collaborate with planners, organizations

involved in disaster relief, government

agencies, health care professionals and

community groups to develop the preparedness

plan is vital

✓ Education in the area of preparedness is

essential in order to reduce barriers that hinder

response to a disaster. Health systems and

society in general may have a responsibility to

provide support and care of health workers’

dependents if the call to respond is to be

heeded. The measures needed must be

identified and planned in advance for maximum

security to be ensured.

RESPONSE

✓ providing both physical and mental health

care

✓ manage scarce resources, coordinating care,

determining if standards of care must be

altered, making appropriate referrals, triage,

assessment, infection control and evaluation

are just a few of the skills a nurse uses in the

response phase

4. RECOVERY/REHABILITATION

  1. long-term recovery of individuals, families and communities.

DISASTER PREPAREDNESS AND

HOW TO CRAFT PLANS

I. THE PHILIPPINE DISASTER RISK PROFILE

The country is archipelagic in nature. it is composed of 7,107 islands and surrounded by numerous bodies of water. The Philippines is located at the western segment of the pacific ring of fire, where the active volcanoes and earthquake generators are found. on average, our country experiences an average of 20 earthquakes a day only a few are felt by men. one of the recent and destructive earthquake events was the Bohol earthquake on October 2013. The Philippines is also located at the pacific typhoon belt. We experience an average of 20 typhoons a year, 5-7 of those are said to be destructive. Typhoon Yolanda is the most devastating amongst the typhoons that entered the par. last year we exceeded the number of typhoons that enter the Philippine area of responsibility (par), we have recorded 26 tropical cyclones. NATURAL HAZARDS

  • Tropical cyclones
  • Floods
  • Storm surges
  • Earthquakes
  • Tsunamis
  • Volcanic eruptions
  • Landslides
  • Drought HUMAN-INDUCED HAZARDS
  • Fire
  • Maritime accidents
  • Aircraft crashes
  • Land accidents
  • Industrial accidents
  • Crimes
  • Civil disturbance
  • Terrorism
  • Armed conflict WHAT ARE THE EFFECTS OF DISASTERS? These are among the many consequences that we have to face given our disaster risk profile. Poor economy, widespread damages, lost livelihood and poor tourism as among the many financial implications of disaster impacts. World Risk Index Report 2014 Because of the frequent disaster events in our country, we are ranked as the 2nd country that is at risk and 3rd most exposed according to the world risk index report 2014.

II. REPUBLIC ACT 10121: THE PARADIGM

SHIFT IN THE PHILIPPINE DRRM SYSTEM

The Philippine Disaster Risk Reduction and Management (PDRRM) Act of 2010 “An Act Strengthening the Philippine DRRM System, Providing for the National DRRM Framework and Institutionalizing the National DRRM Plan, Appropriating Funds Therefor and for Other Purposes” The law that strengthened the presidential decree 1566, is the republic act 10121-the Philippine disaster risk reduction and management act of

  1. it is the act strengthening the Philippine disaster risk reduction and management system, providing for the national DRRMframework and institutionalizing the national DRRM plan and appropriating funds therefore and for other purposes. The law provided for the paradigm shift of disaster management to disaster risk reduction and management or DRRM. The approach on disaster management was centralized and top-down, disasters was merely a function of physical hazards and the focus was on disaster response and anticipation. the current law is participatory and bottoms-up disaster risk reduction. disaster is viewed mainly a reflection of people’s vulnerability and the

approach to reduce disaster risk is integrated to achieve a genuine social and human development. NDCC (National Disaster Coordinating Council)

  • 1 Chairperson and 19 Members NDRRMC (National Disaster Risk Reduction and Management Council)
  • 1 Chairperson, 4 Vice-Chairpersons, and 39 Members III. WHAT IS DISASTER PREPAREDNESS? According to RA 10121, disaster Preparedness is the knowledge and capacities developed by governments, professional response and recovery organizations, communities and individuals to effectively anticipate, respond to, and recover from, the impacts of likely, imminent or current hazard events or conditions. IV. PROGRAMS AND ACTIVITIES UNDER DISASTER PREPAREDNESS
  • Conducting Drills and Exercises
  • Stockpiling and Prepositioning
  • Information and Education Campaigns ➢ such as the distribution of leaflets and flyers. at OCD, we have the Project DINA or disaster information for nationwide awareness, which contains a collection of videos about what to do before, during and after disasters. We also have the Batingaw application for smart phones, which contains useful information and tools on DRRM.
  • Organizing and Capacitating the Council (including disaster volunteers, non-government organizations and the private sector)
  • Training (search and rescue training, first aid training and the incident command system)
  • Formulation and Development of Plans V. NATIONAL DRRM PLAN AND OTHER PLANS Organizing and Capacitating the Council A road map from 2011 to 2028 on how DRRM shall: ✓ contribute to gender responsive and rights based sustainable development, ✓ promote inclusive growth, ✓ build adaptive communities, ✓ increase resilience of vulnerable sectors ✓ optimize disaster mitigation opportunities to promote people welfare and institutions The NATIONAL DRRM plan is complemented by REGIONAL DRRM plans by the regional DRRM councils and the local DRRM plans by the local DRRM councils from provincial down to barangay levels. together, these DRRM plans work together to ensure a comprehensive disaster preparedness road map for the country. National Disaster Response Plan
  • Guide of NDRRMC Member Agencies in preparing agency-level Response Plan
  • Based on actual experiences and observations of national agencies involved in the response operations done for disasters from 2010-2013. Contingency Plan A contingency plan is intended for a certain type of disaster. Its uses are as to predict a specific worst-case scenario of a disaster, to prevent its effects, to reduce its impacts, to respond and to cope with the consequences. Contingency Plan is a forward plan in a state of uncertainty in which:
  1. scenarios and objectives are agreed,
  2. managerial and technical actions defined,
  3. potential response systems put in place in order to prevent, or better respond to, an emergency or critical situation. Uses of Contingency Plan:
  • to predict a specific disaster in a locality (worst case scenario)
  • to prevent its effects
  • to reduce its impact
  • to respond
  • to cope with the consequences Operations Plan
  • Also called Incident Action Plan
  • Formulated and implemented immediately (on- scene)
  • Used to address a specific incident within a specific time frame
  • Contents are actual and precise Another example of plan is the operations plan, which is also called to as the incident action plan. unlike the DRRMplan and the contingency plan, an operational plan is formulated and implemented immediately. it is used to address a

NATIONAL DISASTER RESPONSE

PLAN (NDRP)

Hydro-Met, Earthquake & Tsunami, and

Consequence Management for Terrorism

Related Incidents

WHAT IS NATIONAL DISASTER RESPONSE

PLAN?

It is the Government of the Philippines’ “multi-

hazard” response plan. It outlines the

processes and mechanisms to facilitate a

coordinated response from the national down to

local level agencies.

Local government institutions are responsible

for the development and improvement of local

response plans relative to their areas of

responsibility and underlying risks.

WHERE IS NATIONAL DISASTER

RESPONSE PLAN USED?

NDRP is applicable significantly at the

respective Emergency Operations Center

before, during, and after disaster Response

Operations at the national down to the

provincial level.

WHEN IS NATIONAL DISASTER RESPONSE

PLAN USE?

NDRP is use whenever the Response Cluster

is activated. It became the strategic and

operational reference of Cluster to attain clear

leadership, clear accountability, and clear

predictability.

WHO USES THE NATIONAL DISASTER

RESPONSE PLAN?

NDRP is use by the NDRRMC specifically by

the Vice-Chairperson for Response, PDRA

Core, Response Cluster Leads and Members

Agencies, including all private and volunteer

groups acknowledged by the NDRRMC.

The concept of the national disaster response

system for earthquake and tsunami is divided

into two different phases; the during disaster

and post disaster. There are triggers for

activation that were identified; PHVOLCS

Official Announcement, NDRRMC Advisory,

Reports or No report of Incident or Disaster and

the request from the LGUs. The response

system is working using the Philippine Cluster

Approach System wherein Council members,

government agencies, private / volunteer

groups and CSOs are group into functional

organization to address specific discipline of

disaster response management operations.

These Clusters are working using their

respective operations protocol to PROVIDE

conduct search and rescue, movement of

mobility assets, damage assessment and

needs analysis, early recovery and post

disaster assessments.

In parallel with the Philippine Cluster System,

the International Humanitarian Partners acts as

the Co-Lead for the international community to

attain coordination, collaboration,

communication and cooperation for disaster

management operations.

Today, there are 12 Response Clusters headed

by the Vice-Chairperson for Response, the

Department of Social Welfare and Development

(DSWD). The OCD acts as the operational

coordinator of this Clusters.

The organizational structure is as shown:

Education Cluster Lead Agency is the DepEd;

Health is DOH; International Humanitarian

Relations (IHR) is DFA; Logistics is OCD;

Management of the Dead and Missing (MDM)

is DILG; Protection is DSWD; Food and Non-

Food is DSWD; Search, Rescue and Retrieval

(SRR) is DND-AFP; Law and Order (LO) is

DILG-PNP; Emergency Telecommunications is

OCD; and Camp Coordination and Camp

Management (CCCM) is DSWD.

NDRP COORDINATION MECHANISMS for

HydroMet, Earthquake, Tsunami, and

Consequence Management for Terrorism

Related Incidents

The following levels of action shall be used as

reference at different levels of response:

Alert Level “ALPHA” – occurrence of

incident/s within the maximum capacity of the

Local DRRMC

Alert Level “BRAVO” – occurrence of

incident/s within the maximum capacity of the

Provincial DRRMC

Alert Level “CHARLIE” – occurrence of

incident/s within the maximum capacity of the

Regional DRRMC deployed elements

Alert Level “DELTA” – occurrence of major

incident/s requiring national response

(NDRRMC)

The following levels of action shall be used as

reference at different levels of response:

Level 1: The lowest form of individual and

respective organizational planning. It delves

with specific organizational arrangements to

provide the consequence management

services that the organization is mandated to

deliver.

Level 2: Defines how the lead agency of

specific Cluster and its members will work

together to achieve its specific objectives. It

entails the coordination among Cluster

members under the command and control of

the lead agency of the Cluster.

Level 3: The highest form of preparedness and

response planning and operations. Under this

phase, the Vice Chairperson for Response

provides a common strategic planning and

operational framework and process to warrant

configuration of consequence management

operations to all-encompassing principles and

goals.

UNDERSTANDING BASIC

CONCEPTS IN DRRM

Disaster Risk Reduction Network Philippines (DRRNetphils) The Philippines – a disaster risk epicenter The Philippines lies in an area highly prone to natural hazards, owing to its location and geographic landscape.

  • Archipelagic with a long coastline
  • Located in the Pacific Ring of Fire: earthquakes, tsunamis, volcanic hazards
  • Along the Western Pacific Basin: monsoons, thunderstorms, inter-tropical convergence zones, typhoons, El Niño, La Niña. Archipelagic nature of the Philippine coastal areas - increases susceptibility to storm surges, tsunamis and sea level changes. Located in the Pacific Ring of Fire – earthquakes, tsunamis, volcanic hazards. Lies along the western part of the Pacific Ocean – monsoons, thunderstorms, ITCZ, typhoons, El Niño, La Niña Floods are common due to rains brought by typhoons and the monsoon. Vulnerability in Southeast Asia A January 2009 mapping study done by Dr. Arief Anshory Yusuf and Dr. Herminia Francisco of the Singapore-based Economy and Environment Program for Southeast Asia shows the vulnerability of Southeast Asia alone shows alarming trends. Millions of Filipinos are at risk.
  • The Philippines ranks number one in the whole world in terms of number of reported disaster events within 2009.
  • In 2009 the Philippines ranked second in terms of population affected by natural disasters and third in the world in terms of number of people killed. (Source: CRED EM Data, Human Impact of Disasters, 2009). Disaster Risk Management
  • A range of activities that contribute to increasing capacities and reducing immediate and long-term vulnerabilities to prevent or at least minimize damaging impact in a community

a) Before the disaster

  • Prevention
  • Mitigation
  • Preparedness b) During the disaster – emergency reliefs and responses c) After the disaster
  • Recovery: rehabilitation and reconstruction
  • “Building back better Disaster Risk Reduction
  • It is a proactive approach to minimize vulnerabilities and disaster risks to minimize loss of life, livelihood and property.
  • DRR incorporates aspects of good governance, sustainable development, risk (natural; human; and climate risks) assessments, knowledge and education, risk management, vulnerability reduction, disaster preparedness and response – guided by principles of human rights and security, gender equity and equality, cultural sensitivity and empowering participation.
  • It has been said that every $1 spent on risk reduction saves between $5 and $10 in economic losses from disasters (Eric Schwartz (UN Deputy Secretary General)). DRRM Framework Republic Act No. 10121 “An Act Strengthening the Philippine Disaster Risk Reduction and Management System, Providing for the National Disaster Risk Reduction and Management Framework and Institutionalizing the National Disaster Risk Reduction and Management Plan, Appropriating Funds Therefor and for Other Purposes” “The Philippine Disaster Risk Reduction and Management Act of 2010” (Approved on May 27, 2010; Effective on June 24, 2010) DRRM Act Implementing Rules and Regulations (IRR) – approved on September 27, 2010 Salient Features of RA 10121
  • Coherence with the International Framework
  • Strengthened institutional mechanism for DRRM
  • Integrated, coordinated, multi-sectoral, inter- agency, and community-based approach to disaster risk reduction
  • Adherence to universal norms, principles, and standards of humanitarian assistance
  • Good governance through transparency and accountability
  • Empowerment of local government units (LGUs) and civil society organizations (CSOs) as key partners in disaster risk reduction
  • Integration of the DRRM into the educational system
  • Disaster Risk Reduction and Management Fund (DRRMF) at the national and local levels

clinical picture together with the likely agent by contacting the nearest poison center and discussing the case with their specialist in poison information and medical toxicologist. CHEMICAL COUNTERMEASURES Treatment for exposures to most hazardous chemicals is limited to decontamination and supportive care. However, medical countermeasures do exist for some chemical agents and it is important to recognize the opportunity to administer an antidote to the victim when one exists and if the right indications for it are present. OCCUPATIONAL SAFETY AND HEALTH ADMINISTRATION (OSHA) LEVEL A, B, C, AND D PROTECTION AGAINST CHEMICAL SUBSTANCES. Hazardous material (HAZMAT) is any substance with the potential to harm people, property, or the environment.

✓ Includes not only chemicals, but also biological, radiological, nuclear, and explosive substances. ✓ Intended or have the capability to cause death or serious bodily injury to a significant number of people or known as CBRN(chemical, biological, radiological, nuclear). 6 PRIMARY CLUES FOR HAZMAT PRESENCE

  • Occupancy/Location : provide identification as to the involved materials.
  • Container Type : provides a good indication as to the as to the contents.
  • Markings/Colors : facilities and vehicles must use special markings, including identification numbers and colors, to indicate the presence of HAZMAT
  • Placards/Labels : placards are used when HAZMATs are being stored in bulk, such as in cargo tanks. Labels are in small containers.
  • Shipping papers : provide the shipping name, hazard class, identification number and quantity, and may indicate whether is waste or poison.
  • Senses : Odor, vapor clouds, dead animals, and dermal/ocular irritation can indicate the presence of HAZMATs. HAZMAT EMERGENCY RESPONSE Standardized by both OSHA (Occupational Safety and Health Administration) and National Fire Protection Association (NFPA). Responders arriving at the scene must be capable of determining that a HAZMAT incident has occurred.
  • Also responsible to call a HAZMAT team for assistance.

DETECTION OF CHEMICAL AGENTS

  • HAZMAT teams are routinely equipped with a variety of chemical detectors and monitoring kits, primarily chemical-specific tests indicating only the presence or absence of a chemical.
  • The goal of chemical weapons detectors and sensors is to alert to an imminent danger.
  • Handheld portable alarm detectors
  • monitoring dose meter detectors are now used for control of contaminated and decontaminated areas, chemical disarmament, water contamination control, and medical sorting of casualties. CHEMICAL AGENTS OF CONCERN The categories/types used by the CDC are as follows (CDC, 2016): ▪ Biotoxins ■ Blister agents/vesicants ■ Blood agents ■ Caustics (acids) ■ Choking/lung/pulmonary agents ■ Incapacitating agents ■ Long-acting anticoagulants ■ Metals ■ Nerve agents ■ Organic solvents ■ Toxic alcohols ■ Vomiting agents ■ Riot control agents/tear gas CWAs are classified into groups:
  • nerve agents
  • biotoxins (e.g., ricin),
  • vesicants (blistering agents),
  • tissue (blood) agents,
  • pulmonary agents,
  • riot control agents. ✓ Rapid onset of symptoms that often occurs within minutes of the initial exposure (Burda & Sigg, 2001). ✓ To minimize casualties, there must be prompt initiation of rescue, decontamination, medical attention, and antidotal therapy ✓ Clinicians cannot rapidly detect the presence of an agent within the body but must look for some by-product of the agent or a particular expression of symptoms (e.g., Diarrhea, Urination, Miosis, Bradycardia, Bronchorrhea, Bronchospasm, Emesis, Lacrimation, Salivation, Sweating [ DUMBBBELSS], ✓ symptoms suggestive of cholinergic poisoning from nerve agents) that is suggestive that a chemical exposure has taken place. MEDICAL MANAGEMENT Primary Assessment and Resuscitation
  • For victims exposed to liquid and solid chemicals, decontamination by wearing the appropriate PPE should precede resuscitation and primary assessment to prevent secondary contamination of unprotected healthcare providers.
    • All victims of a HAZMAT incident should be considered contaminated, regardless of on-site decontamination measures (Cox, 2016).
    • Resuscitation and primary assessment using Airway, Breathing, Circulation, Disability, and Exposure (ABCDE).
    • Circulation takes priority before airway and breathing (CAB) in victims with massive external hemorrhage or primary cardiac arrest, such as ventricular fibrillation or pulseless ventricular tachycardia (Ewy & Bobrow, 2016).
    • Bleeding with exsanguinating hemorrhage- controlled with direct pressure or a tourniquet on the affected extremity.
    • Primary cardiac arrest may occur after exposure to hydrocarbons (ventricular irritability) and hydrofluoric acid (hyperkalemia/hypocalcemia) and should be initially managed with minimally interrupted cardiac resuscitation (MICR) with passive oxygen insufflation. A = Airway (with spine stabilization and control, if needed) ➢ Ensure an open and protected airway; suction as needed. ➢ Temporizing airway management with oropharyngeal/ nasopharyngeal devices may be adequate during decontamination. ➢ Endotracheal intubation is the preferred airway management technique, when possible. ➢ Cricothyroidotomy may be required in victims with orofacial trauma or oropharyngeal/ epiglottic/laryngeal edema. B = Breathing Ensure adequate ventilation and oxygenation. If victims are not breathing or not breathing adequately, assist with a bag-valve- mask and 100% oxygen, then intubate. If victims are able to protect their airway and breathing adequately, administer 100% oxygen to those with cardiopulmonary or neurological symptoms or potential exposure to chemical asphyxiants . C = Circulation Check for a pulse. If absent, begin cardiopulmonary resuscitation (CPR) or MICR, then check the rhythm and follow Advanced Cardiac Life Support (ACLS) guidelines. If the victim has a pulse, monitor the blood pressure and cardiac rhythm; follow ACLS guidelines. An IV of normal saline should be started on all victims with more than mild signs or symptoms. Monitor for shock and treat appropriately. D = Disability (Nervous System) Continually assess the victim’s level of consciousness and neurological status. Victims with any neurological signs or symptoms should receive 100% oxygen. If seizures develop despite adequate oxygenation

and normal glucose, treat with IV, IM, or IO benzodiazepines. E = Exposure The victim’s clothing should have been removed during any needed decontamination. Careful attention should be paid to gas exposures as the victim’s clothing could trap fumes and expose healthcare providers. Thoroughly assess the victim for signs of trauma, burns, and frostbite SECONDARY ASSESSMENT

  • Secondary assessment of HAZMAT victims includes history and physical examination.
  • This secondary assessment focuses on identifying a toxic syndrome (toxidrome), recognizing any preexistent illnesses, anticipating potential complications, and assessing for concurrent trauma.
  • A = Allergies: Determine whether the victim is allergic to any substance or had an adverse event in the past.
  • M = Medications Determine what medications the victim is prescribed. Current medications can give clues to the victim’s preexistent illnesses and could also interact with resuscitative or antidotal therapies.
  • P = Past Medical History Determine the victim’s past medical history as preexistent illnesses can exacerbate reactions to various chemicals (e.g., asthmatics exposed to pulmonary irritants)
  • L = Last Determine the last normal menstrual period in reproductive age women to assess for potential fetal toxic exposures. Determine the last tetanus shot in victims with open wounds. Determine the victim’s last meal to assess aspiration risk during endotracheal intubation.
  • E = Events Determine the events surrounding the HAZMAT incident. Are there other victims who need to be rescued? When did the incident occur? Where did the incident occur? What HAZMAT was involved in the incident? What was the route(s) of exposure? How long was the victim exposed to the HAZMAT? What treatment(s) has already been administered? NERVE AGENTS
  • Nerve agents are among the most potent and deadly of the chemical weapons. They are rapidly lethal and hazardous by any route of exposure (Reutter, 1999; Tucker, 2006).
  • Nerve agents are liquids at room temperatures with the capability of producing a vapor that may be well absorbed through the skin as well as the lungs and gastrointestinal (GI) tract. Nerve agents are classified in two groups(Reutter, 1999).
  1. G
  2. V ✓ The G agents include GA (tabun), GB (sarin), GD (soman), and GF. ✓ The V agents, which tend to be more pernicious, include VG (amigon), VS, and VX. ✓ These agents are all highly poisonous chemicals that act by binding to the enzyme acetylcholinesterase.Organophosphate pesticides and Carbamate pesticides work in exactly the same way, and are recognized in the same fashion as nerve agents. also act on the same enzyme, causing similar symptoms. Recognizing Nerve Agents
    • Persons exposed to high concentrations of organophosphate nerve agents usually develop signs and symptoms within a matter of minutes after exposure.
    • Clinical presentation of patients with gasping, miosis, copious secretions, sweating, and generalized twitching is very suggestive of nerve agent exposure (Weinstein & Alibek, 2003).
    • Initial patient diagnoses and treatments are likely to be based on observations of signs and symptoms by the paramedic or other healthcare professionals at the scene.

VESICATING/BLISTER AGENTS

Vesicants/blister agents are chemicals that severely blister the eyes, respiratory tract, and skin on contact. Possible substances included in this class are mustard agents, lewisites/chloro arsine agents, and phosgene oxime (Alibek et al., 2006).

**- Sulfur mustard has been used as a CWA in several wars.

  • Thioglycol, an immediate precursor to sulfur mustard, has many industrial uses and is commercially available. Nitrogen and sulfur mustards and lewisite are cytotoxic alkylating agents.
  • Sulfur mustard reacts within minutes with components of DNA, RNA, and proteins, and interrupts cell function.
  • Mustard is the only one of the vesicants that does not cause immediate pain (Sidell, Urbanetti, Smith, & Hurst, 1997).
  • Clinical signs and symptoms may develop within 2 to 12 hours but typically develop after 12 hours.
  • Ocular and pulmonary injuries also may occur, and respiratory involvement is the most common cause of mortality.
  • Mortality ranges from 2% to 3%. Approximately 5 to 7 mL (100 mg/kg) of mustard spread over 25% of the body surface area is potentially lethal (Davis & Aspera, 2001).
  • Exposure is characterized by immediate, severe pain and skin lesions similar to those caused by exposure to a strong acid (Sidell, 1997). Recognizing Vesicants** - Rapid recognition of vesicating agents in an emergency is a key step to ensure rapid and effective care. - Many blister agents are similar in appearance, they may be differentiated based on their distinctive odor. Treatment
    • Blister/vesicant exposure is treated primarily as a thermal burn.
    • Sulfur mustard decontamination is limited to immediate washing of exposed skin with water or soap and water, and flushing the eyes with copious amounts of water.
    • Avoid 0.5% sodium hypochlorite solution or vigorous scrubbing as they may cause deeper tissue penetration.
    • Typical burn therapy is accomplished with antibiotic ointment, sterile dressing, and other supportive therapy.
    • Patients whose burns cover more than 20% to 25% of body surface area should be admitted to critical care units even though at presentation they may have relatively few signs and symptoms (Davis & Aspera, 2001). Duration/Mortality
    • The severity of the illness is dependent on the amount and route of exposure to the vesicant, the type of vesicant, and the medical condition of the person exposed. Exposure to high concentrations may be fatal.

Patient Assessment

  • • All of these vesicant agents act by producing direct irritation and have similar clinical presentations.
  • Ocular: Redness and burning of the eyes with lacrimation, blepharospasm, and lid edema
  • Upper airway : Nasal irritation and discharge, sinus burning, nose bleeds, sore throat, cough, and laryngitis
  • Pulmonary : Dyspnea, necrosis of large airway mucosa with sloughing, chemical pneumonitis, pulmonary edema, ARDS, respiratory failure
  • Skin: Irritation and redness with delayed production of wheals, vesicles, or bullae, followed later by areas of necrosis Clinical Diagnostic Tests ■ CBC ■ Glucose ■ Serum electrolytes and renal function (blood urea nitrogen [BUN]/creatinine) ■ Chest x-ray ■ Pulse oximetry (or arterial blood gas [ABG] measurements). Patient Management
  • Decontaminate patients before treating. Provide supportive therapy. Patient Management
  • Decontaminate patients before treating. Provide supportive therapy. Therapy
  • There is no countermeasure; good supportive care is needed. Blood Agents
  • Blood or tissue agents are chemicals that affect the body by being absorbed into and distributed by the blood to the tissues.
  • Substances include arsine, carbon monoxide, cyanide agents, and sodium monofluoroacetate.
  • They may act on the blood itself or more distally in the critical tissues.
  • Arsine is most commonly used in the semiconductor and metals refining industries.
  • Inhalation is the primary route of exposure, causing red blood cell lysis and symptoms including weakness, shortness of breath, possible loss of consciousness, respiratory failure, paralysis, and death.
  • Severely exposed patients are not likely to survive. If the initial exposure is survived, long- term effects may include kidney damage, neuropathy, and neuropsychological symptoms.
  • Initial treatment includes fresh air, removal of contaminated clothing, washing contaminated skin, and symptomatic and supportive care.
    • There is no specific countermeasure for treatment of arsine poisoning.
    • Patients may need blood transfusions to replace damaged red blood cells (Walter, 2003; Weinstein & Alibek, 2003). Recognizing Tissue (Blood) Agents
    • Cyanide in chemical weapons comes in four forms. – cyanogen chloride (CK),
    • hydrogen cyanide (AC),
    • potassium cyanide (KCN),
    • sodium cyanide (NaCN). All forms such a liquid, aerosol, or gas for inhalation; they may also be ingested or absorbed through the eyes and skin (Weinstein & Alibek, 2003). Sources of exposure include fumigants (rodenticides and insecticides), military poison gas, fire by-products, gold and silver ore extrication, mining, electroplating, and steel production. There are three main laboratory findings indicative of cyanide exposure: (a) an elevated blood cyanide concentration (the most definitive); (b) metabolic acidosis with a high concentration of lactic acid; and (c) oxygen content of the venous blood greater than normal (although this is not specific to cyanide exposure) Patient Assessment Cyanide Poisoning:
    • The latency period for cyanides is 10 to 15 seconds up to several minutes.
    • The signs and symptoms of mild cyanide poisoning are nonspecific and may be difficult to differentiate from other CWAs.
    • The signs and symptoms of moderate-to-severe cyanide poisoning are profound and may appear similar to those of the nerve agents, but are most consistent with tissue hypoxia.
    • CK is an irritant and may produce lacrimation and upper airway irritation.
    • Exposed to low concentrations of the other three forms of cyanide, victims will have 10 to 15 seconds of gasping, tachypnea, tachycardia, flushing, sweating, headache, giddiness, and dizziness, followed by nausea, vomiting, agitation, and confusion.
    • At higher concentrations, the victim will have all these initial signs and symptoms, followed by bradycardia, apnea, seizures, shock, coma, and death. In all cases, death is caused by respiratory arrest and can be prevented by CPR. Clinical Diagnostic Tests ■ CBC ■ Blood glucose ■ Electrolyte determinations ■ Urine for hemoglobinuria Treatment
