Introduction
*This assessment is designed to prepare candidates for the California Certified Asbestos Consultant (CAC) Exam
100. It evaluates mastery of federal and California-specific asbestos regulations, technical abatement standards,
air monitoring protocols, and professional ethics. The exam uses multiple-choice and scenario-based questions
that require real-world application, regulatory interpretation, and critical decision-making. Emphasis is placed
on Cal/OSHA Title 8, EPA NESHAP, AHERA, and DTSC waste handling rules. Each correct answer is verified and
followed by a rationale explaining the regulatory or scientific basis. No dates are included to ensure evergreen
utility.*
,SECTION ONE: QUESTIONS 1–100
Question 1
A CAC is called to inspect a school built in 1978. Under AHERA, which of the following actions is required before
sampling suspected asbestos-containing material (ACM)?
A. Notify parents of all students within 500 feet
B. Obtain a written waiver from the local air district
C. Develop a management plan including a blueprint of sampling locations
D. Perform a three-point bulk sampling protocol per location
🟢D
🔴 RATIONALE: AHERA (40 CFR 763.86) requires that each homogeneous area of suspected ACM be sampled
using a minimum of three bulk samples per area. The other options are not AHERA sampling prerequisites.
Question 2
A building owner wants to remove less than 100 square feet of non-friable asbestos-containing floor tile. Under
Cal/OSHA (Title 8, CCR 1529), this activity is classified as:
A. Class I asbestos work
B. Class II asbestos work
C. Class III asbestos work
D. Class IV asbestos work
🟢C
,🔴 RATIONALE: Class III asbestos work involves repair and maintenance operations where only ACM is
disturbed, including removal of non-friable materials like floor tile if less than 100 sq ft, provided it remains
non-friable during removal.
Question 3
During a pre-abatement inspection, you find severely damaged pipe insulation containing 40% chrysotile. The
pipe runs through a mechanical room with no windows. What is the minimum required containment under
Cal/OSHA for a Class I removal of this size?
A. Glovebag only
B. Mini-enclosure with local exhaust
C. Full containment with negative pressure and decontamination unit
D. No containment if workers wear supplied-air respirators
🟢C
🔴 RATIONALE: Cal/OSHA Title 8 §1529 requires full containment (critical barriers, negative pressure,
decontamination facility) for Class I jobs involving friable ACM in indoor settings, regardless of respirator type.
Question 4
A CAC reviews an abatement contractor’s daily air monitoring results. OSHA’s permissible exposure limit (PEL)
for asbestos (8-hour TWA) is:
A. 0.1 f/cc
B. 0.01 f/cc
C. 1.0 f/cc
D. 0.5 f/cc
, 🟢A
🔴 RATIONALE: OSHA 29 CFR 1910.1001 and 1926.1101 set the PEL at 0.1 fibers per cubic centimeter (f/cc) as
an 8-hour time-weighted average. The excursion limit is 1.0 f/cc over 30 minutes.
Question 5
You are hired to write an asbestos operations and maintenance (O&M) plan for a high-rise office building.
Which of the following must be included per EPA guidance?
A. Annual medical exams for all office tenants
B. A schedule for re-inspection of known ACM every 3 years
C. A requirement to remove all floor tile regardless of condition
D. An emergency response procedure for fiber release episodes
🟢D
🔴 RATIONALE: EPA’s “Managing Asbestos in Place” guidance requires emergency procedures for fiber release
episodes as part of an O&M plan. Three-year re-inspections are for schools under AHERA, not all buildings.
Question 6
A CAC observes a worker removing transite siding from an exterior wall. The siding is being cut with a circular
saw without a HEPA vacuum attachment. This violates:
A. NESHAP work practice standards only
B. Cal/OSHA Title 8 §1529 only
C. Both NESHAP and Cal/OSHA
D. DTSC waste manifest requirements only
