- Before doing the work (pre employment, pre placement)
- Annually
- Upon termination (Cal OSHA requirement) What should be performed at an asbestos medical surveillance exam? Occupational History Exam, Chest X ray, Pulmonary Function Test, stool sample Is there a safe level of asbestos exposure? no What are the 7 major components of the AHERA law? Whom do they apply?
National Emission Standards for Hazardous Air Pollutants (NESHAP) , APCD what are the 3 categories of materials that an inspector must look for when conduction a NESHAP building inspection? Friable Materials , Category 1 non friable, and Category 2 Non Friable What is a Friable material via NESHAP?
1% asbestos that can be crumbled into dust by hand pressure. What is a Category 1 non friable, and Category 2 Non Friable Via NESHAP? non friable materials including packing, gaskets, resilient floor covering, and asphalt roofing products, ACM products not in category 1 (usually cementitous products) What is RACM? Regulated asbestos containing material.
When is a NESHAP notification required? Required for all demolition even if no ACM. When is a FED EPA notification required? whenever more than 160 square feet, 250 linear feet, or one cubic meter will be disturbed as part of a renovation What is the federal OSHA regulation that regulates asbestos exposure for construction? 29 CFR 1926. what types of work are included in OSHA's 29 CFR 1926. demolition, salvage, removal, encapsulation of ACM, construction, alteration of ACM or construction, alteration, repair, maintenance, renovation, or clean up of debris. What is the PEL for ACM? What is the Excursion limit? 0.1 f/cc 8 hr / TWA , 1.0 f/cc over 30 minutes at peak exposure time.
Define Class 3 via 29 CFR 1926. Designed to regulate work involving small amounts of asbestos (TSI, surfacing, PACM, or ACM) that is disturbed (will fit into one glove bag or standard waste container). Determined by SIZE of job. Define Class 4 via 29 CFR 1926. Designed to regulate custodial work around nonfriable materials. thus its designed for workers who contact but do not disturb asbestos! When can a contractor cease air monitoring? a negative exposure assessment can be achieved via air sampling to document no exposure via PEL and Exursions for class 3 and 4 work. Can a contractor cease personal air sampling for class 1 and 2 work? no what is the cal osha asbestos standard CFR 1529
What are the major differences between CFR 1529 and 29 CFR
1529 requires written report of use, registration for over 100 sq. feet, notification for temporary worke sites, consultant / technician licensing and Carcinogen report of use requirements found in 8 CCR 5203. Describe the implications of simply following regulations versus maintaining state of the art practices liability may be based on state of the art practices. identify the most likely parties to a legal action against a contractor building owners, building occupants, other 3rd parties Claims madre insurance vs occurance insurance? Claims made = claims made during policy period, Occurence = insures occurence taking place during the policy period regardless of when the claim is made.
Can altering fire proofing in buildings affect insurance and fire proofing of buildings? YES, adding encapsulant or removing fire proofing can greatly reduce the flame retardant nature of fire proofing. What is an Architectural drawing? show finished surfaces and materials of a building. What is an structural drawing? Foundation, floor, framing, rood framing etc Mechanical drawing? HVAC systems Plumbing Drawing? Plumbing systesms
Electrical Drawing? floor plan based power and lighting plans What is a Underwriters (UL) rating indicate provides rating of fire resistance in hours for a particular building assembly. what would 1 pipe coming from a piece of building equipment be? an expansion tank what would 2 pipes coming from a piece of building equipment be? storage tank what would 3 pipes coming from a piece of building equipment be? boiler heater
Do you need to resample materials that were already sampled before by a non accredited individual? Not if an accredited inspector signs and dates a statement that declares the previous samples were sampled within compliance of AHERA What are the things a AHERA accredited inspector must do in an AHERA inspection? visually inspect every area , touch all suspect acm materials to determine friability, identify type of product (TSI , surfacing, misc), sample each suspect material or assume its ACM , document, determine condition. what is the difference between an inspection and an assessment inspection involves touching materials, identifying suspected materials, and taking samples assessment involves assessing the damange (if any) of the material and placing it in a specific category what is Adhesion
means adhered to the substrate or insulated component what is Cohesion means material with structural integrity Define extent means whether the damage is localized or distributed over a broad area. Damage is extensive if localized damage amounts to more than 25% of the material or damage is distributed over 10% of the material. Define Severity means whether the damage is superficial or deep. Superficial might include water stains, flaking, blistering, abrasions or scratches. Deep might include major separation of layers gouges, water damage, punctures, tears, etc. what is the difference between periodic and episodic damage? Periodic damage is recurring or continuous. For example, periodic damage results from the abrasion of TSI when a worker steps on it
Damaged friable ACBM in an area regularly used by building occupants, including maintenance personnel in the course of their normal activities; there are indications that the material will become significantly damaged, delaminated or deteriorated, AND the material is subject to continuing major disturbance. What is Accessible by AHERA? Material is subject to disturbance by building occupants or custodial or maintenance personnel in the course of their normal activities. What is Exposed by AHERA? Material that is not concealed from view by any kind of barrier, such as a drop ceiling, a radiator housing, or a metal jacket What is Functional Space by AHERA? Distinct units within a building that serve similar purposes, have similar occupants, etc. How do you decide whether damaged material should be assessed as "damaged" or "significantly damaged?"
How extensive is it? (Is it over 10% distributed or 25% localized?) How severe is the damage? (Is it superficial, deep, major?) Is the damage extensive and severe? Is this the worst damage in the building? Do you want to insure management planner grasps severity? Are other factors involved such as heavy occupant use, etc? How do you decide whether a material is assessed as potential damage or potential significant damage? Is the material already damaged? (In general, potential significant damage is used for materials that are already damaged). Is the expected damage going to be significant or minor? Is there a change in building use that will create a potential for damage? Is there continuing major disturbance? The fifth floor of an office building has 10 identical offices (5 on each side of a common hallway) used by clerical and administrative staff. There is a drop ceiling, and an open air-plenum with sprayed fireproofing over the entire floor. Near the end of the hall is an unlocked mechanical/electrical room. Next to it is a closet where custodial supplies are kept. Across the hall are men and women's restrooms. At each end of the hall are stairways with exposed fire proofing on the ceiling and insulated risers. If you were only inspecting this floor, what functional spaces would you divide it into and why?
