What is the primary type of asbestos used in the U.S ?: Chrysotile.
List three building materials / locations where ACM is likely to be found- : There are over 3000 building products that may contain asbestos. A limited list of examples are: taping mud, flooring mastics/adhesives, popcorn ceilings, fireproof- ing, vinyl floor tiles, sheet flooring backing, transite, fire doors, fume hoods, felt under roofs or siding, kiln bricks and cement, lab equipment, fire safety equipment, auditorium curtains, gaskets, vibration joints, HVAC duct tape, and many many more.

the permissible exposure limit for 30 or more days per year, or engage in Class I, II or III work for a combined total of 30 or more days per year, a medical examination must be given within 10 working days following the thirtieth day of exposure;

And at least annually thereafter.
If the examining physician determines that any of the examinations should be pro- vided more frequently than specified, the employer shall provide such examinations to affected employees at the frequencies specified by the physician.

Exception: No medical examination is required of any employee if adequate records show that the employee has been examined in accordance with this sub- section within the past 1 year period.
Employers shall provide a medical examination at the termination of employment for any employee who has been exposed to airborne concentrations of asbestos at or above the permissible exposure limit and/or excursion limit.The medical examination shall be given within 30 calendar days before or after the date of termination of employment.
What should be performed at an asbestos medical surveillance exam ?: 1. A medical and work history with special emphasis directed to the pulmonary, cardiovascular, and gastrointestinal systems.
On initial examination, the standardized questionnaire contained in Part 1 of Ap- pendix D in 8 CCR 1529, and, on annual examination, the abbreviated standardized questionnaire contained in Part 2 in 8 CCR 1529.
A physical examination directed to the pulmonary and gastrointestinal systems, including a chest roentgenogram to be administered in accordance with Table 2 [8 CCR 1529 (m) (2)(B)3], and pulmonary function tests of forced vital capacity (FVC) and forced expiratory volume at one second (FEV(1)). Interpretation and classifica- tion of chest roentgenograms shall be conducted in accordance with Appendix E in 8 CCR 1529
Any other examinations or tests deemed necessary by the examining physician.
According to CalOSHA how often should you have a chest roentgenogram (X-ray): Years since first occupational exposure:

Management Planner - 2 days Contractor Supervisor - 5 days Abatement Worker - 4 days Project Designer - 3 days

When is unaccredited in-house training acceptable ?: Class III (16 hours), Class IV (minimum 2 hours), and asbestos awareness trainings.
What regulation and agency requires an asbestos inspection be done prior to renovations and demolitions and requires removal of friable ACM prior to demolition ?: National Emission Standards for Hazardous Air Pollutants (NESHAP) enforced by the EPA and it's delegated Air Quality Management Districts. CalOSHA also requires inspections for worker safety.
What are the 3 categories of materials identified in a NESHAP building inspection ?: Friable Materials , Category 1 non friable, and Category 2 Non Friable
What is a friable asbestos material according to NESHAP?: Any material containing more than 1 percent asbestos as determined using the PLM method, that, when dry, can be crumbled, pulverized, or reduced to powder by hand pressure.
What does NESHAP stand for?: National Emissions Standards for Hazardous Air Pollutants
What is a Category 1 nonfriable ACM, and Category 2 nonfriable ACM ac- cording to NESHAP?: Category 1 nonfriable asbestos-containing material means asbestos-containing packings, gaskets, resilient floor coverings, and asphalt roofing products containing more than 1 percent asbestos as determined by PLM. Category 2 nonfriable ACM means any material, excluding Category 1 nonfriable ACM, containing more than 1 percent asbestos as determined by PLM.

What is RACM?: Regulated asbestos containing material (RACM) means (a) Friable asbestos material (b) Category 1 nonfriable ACM that has become friable, (c) Category 1 nonfriable ACM that will be or has been subjected to sanding, grinding, cutting or abrading, or (D) Category 2 nonfriable ACM that has a high probability of becoming or has become crumbled, pulverized, or reduced to powder by the forces expected to act on the material in the course of demolition or renovation operations regulated by the NESHAP.
Is a NESHAP notification required for demolition of a facility even if no asbestos was found during the inspection?: Yes
When is a FED EPA (NESHAP) notification required for asbestos abatement ?: On renovation projects involving more than 160 square feet, 260 linear feet or 35 cubic feet of RACM. EXCEPTION: Local air quality management districts may have rules that supercede this requirement (i.e. Bay Area Air Quality Management District requires notification for greater than 100 square or linear feet of ACM)

mechanical means will render it friable. Therefore, it is RACM and the AQMD must be notified prior to removal.

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 1926.1101: demolition, salvage, removal, encapsulation of ACM, construction, alteration of ACM or con- struction, alteration, repair, maintenance, renovation, or clean up of debris.
What does PEL stand for? What is the PEL for asbestos? What is an EL? What is the EL for asbestos?: Permissible Exposure Limit. 0.1 f/cc for an 8 hour time weighted average (TWA). Excursion Limit 1.0 f/cc over 30 minutes at peak exposure time.

What does PACM stand for? What materials are PACM ?: Presumed As- bestos Containing Materials.

PACM means thermal system insulation and surfacing material found in buildings constructed no later than 1980.

What are the four classes of work defined by Cal OSHA 29 CFR 1926.1101- : Class 1 , Class 2 , Class 3, and Class 4
Define Class 1 from 29 CFR 1926.1101: means activities involving the removal of TSI and surfacing ACM and PACM. (in amounts greater than 1 glove bag)
Define Class 2 from 29 CFR 1926.1101: means activities involving the removal of ACM which is not TSI or surfacing material. This includes, but is not limited to, the removal of asbestos-containing wallboard, floor tile and sheeting, roofing and siding shingles, and construction mastics. (in amounts greater than 1 glove bag)
Define Class 3 from 29 CFR 1926.1101: means repair and maintenance oper- ations, where "ACM", including TSI and surfacing material is likely to be disturbed. (in amounts no greater than 1 standard sized [60" x 60"] glove bag)
Define Class 4 from 29 CFR 1926.1101: means maintenance and custodial activities during which employees contact ACM and PACM and activities to clean up waste and debris containing ACM and PACM.
What engineering controls are always required regardless of the class of work?: 1. Vacuum cleaners equipped with HEPA filters (except for some roof jobs)
Wet methods (except where not feasible)
Prompt clean up
In addition to the engineering controls required regardless of the class of work, what control methods are required to achieve compliance with the PEL and EL?: 1. Local exhaust ventilation with HEPA filter
Enclosure or isolation of removal processes

What controls methods are required for a Class I Negative Pressure Enclo- sure (NPE)?: 1. NPE may be of any configuration
Must have at least 4 air changes an hour
A minimum of - 0.02 column inches of water pressure differential
Must be kept under negative pressure the entire time it's in use
Air movement shall be directed away from employees performing the asbestos work and towards a filtration device with HEPA filters.
A contractor is going to remove floor tile and mastic from a large single room. The dimensions of the room is 50' wide, 100' long, and 20' high. They intend to use negative air machines that can pull 2000 cubic feet per minute (cfm). What is the quantity of floor tile and mastic to be removed? What is the volume of air in the room? How many negative air machines will they need to use to get a minimum of 4 air changes per hour (ACH)?: They are removing 5,000 square feet of floor tile and 5,000 square feet of floor tile mastic. There is 100,000 cubic feet of air in the room. Assuming there is good air circulation in the room and the negative air machines really are pulling 2000 cfm, they will need a minimum of 4 negative air machines to get 4 air changes an hour.
Is the removal of TSI with a glovebag a one man job?: No. It requires two workers for Class I abatement using glovebags.
Are Class II asbestos abatement projects required to be performed under negative pressure according to CalOSHA?: No.
When can a contractor cease air monitoring ?: If the periodic monitoring required by

subsection (f)(3) of 8 CCR 1529 reveals that employee exposures, as indicated by statistically reliable measurements, are below the permissible exposure limit and excursion limit the employer may discontinue monitoring for those employ- ees whose exposures are represented by such monitoring.

True/False. A contractor can cease personal air sampling for class 1 and 2 work with a negative exposure assessment?: True
At what level of exposure does CalOSHA regulate exposure to asbestos?- : Any level of asbestos exposure is regulated by CalOSHA.
What is the definition of an Asbestos Containing Construction Material in California?: Means any manufactured construction material which contains more than 0.1% asbestos by weight.
What is a CIH?: A Certified Industrial Hygienist means one that is certified in the practice of industrial hygiene by the American Board of Industrial Hygiene (ABIH).

under either contract or tort.

What is the difference between contract and tort liability?: Contract Liability refers to not fulfilling the terms of a previously-agreed upon contract. Tort Liability refers to a civil wrong for which the law provides a remedy of money damages. This is often due to negligence. A complainant must show injury or damage caused by someone else's breach of duty or rule of conduct.
Identify the most likely parties to a legal action against a contractor: build- ing owners, building occupants, other 3rd parties
Describe the difference between claims-made insurance and occur- rence-based insurance ?: Claims made - Claims can be made only during the policy period for something that occurred during the policy period. Occurrence - insures occurrences that take place during the policy period regardless

of when the claim is filed. A claim can be filed at any time during, or after, the policy period as long as the occurrence took place during the policy period.

What are the types of insurance a building owner would want an asbestos contractor to possess before being allowed to work in the building ?: Workers compensation, comprehensive general liability, and errors and omissions.
Why is a systems approach to building inspection favorable over a com- ponent system?: Knowing the types of systems in a building will allow you to anticipate where components are located even when they are hidden, and to determine homogeneous areas related to systems. A component approach is limited to counting what you seen in an individual space.
Why is a fire rating of a building/building material important to an inspector ?: fire rating may indicate the use of suspect ACM (e.g. fire-rated doors).
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 ?: Shows finished surfaces and materials of a building.
What is on a structural drawing ?: Includes the foundation, floor, framing, roof framing, ceiling construction, etc
What is on a mechanical drawing ?: Includes mainly the HVAC system. This can include water pipe systems used for heating and cooling air systems.
What is on a plumbing drawing ?: Includes plumbing details for non-me- chanical purposes. This will include both fresh water purposes and disposal/sewer purposes.
What is on an electrical drawing ?: A floor plan with power utility and lighting details.
Where in a building would asbestos fireproofing most likely be ?: On unen- closed steel

shall:

Visually inspect the area to identify the locations of all suspected ACBM.
Touch all suspected ACBM to determine whether they are friable
Identify all homogeneous areas of friable suspected ACBM and all homogeneous areas of nonfriable suspected ACBM.
Assume that some or all of the homogeneous areas are ACM, and, for each homogeneous area that is not assumed to be ACM, collect and submit for analysis bulk samples.
Assess friable material in areas where samples are collected, friable material in areas that are assumed to be ACBM, and friable ACBM identified during a previous inspection.
Record the all the information in a report and submit to the client.
According to AHERA, what information is required to be reported to the representative of the local education agency within 30 days of an inspec- tion?: 1. Inspection report with the date of the inspection signed by each accredtied person maing the inspectin, state of accreditation, and if applicable, his/her accred- itation number.
An inventory of the locations of the homogeneous areas where samples are collected, exact locations, dates, and areas of assumed ACMs.
Methodology for collection of the samples
List of materials and their type (TSI, surfacing or misc.)
Assessments of friable materials
What is the difference between an inspection and an assessment: An inspection involves identifying suspect asbestos containing materials and homoge- neous areas, touching materials, and possibly collecting samples. An assessment involves assessing the damage and/or potential for damage of the material and placing it in one of 7 damage categories

What are the 7 damage categories under AHERA?: 1. Damaged or signifi- cantly damaged TSI ACM
Damaged friable surfacing ACM
Significantly damaged friable surfacing ACM
Damaged or significantly damaged friable miscellaneous ACM
ACBM with potential for damage
ACBM with potential for significant damage
