DOMAIN 1: Asbestos Regulations, Laws & AHERA Inspections (10 Questions)
Sub-Topic: AHERA 3-Year Reinspection (2 Questions)
Question 1 (Multiple Choice) Under EPA AHERA regulations, how frequently must a
reinspection of asbestos-containing materials (ACM) be conducted in a school building?
A) Annually B) Every 2 years C) Every 3 years D) Every 5 years
[CORRECT: C]
Rationale: Per EPA AHERA (40 CFR Part 763, Subpart E), a reinspection of all ACM in school
buildings must be conducted every 3 years by an accredited inspector. This requirement ensures
ongoing assessment of ACM condition and potential fiber release. The precise regulatory factor
is that AHERA mandates periodic verification to protect students and staff from deteriorating
ACM.
Question 2 (True/False) Under AHERA, the 3-year reinspection may be conducted by any
maintenance employee of the school district who has reviewed the original inspection report.
A) True B) False
[CORRECT: B]
Rationale: Per EPA AHERA (40 CFR 763.85), the 3-year reinspection must be conducted by an
accredited asbestos inspector who has successfully completed EPA-approved training. A
maintenance employee, regardless of experience, cannot perform this function without proper
accreditation. The precise regulatory factor is ensuring qualified personnel evaluate ACM
condition to prevent misidentification of hazards.
Sub-Topic: OSHA 1926.1101 "Competent Person" (3 Questions)
,Question 3 (Multiple Choice) Under OSHA 1926.1101, which qualification is specifically
required for an individual designated as the "Competent Person" on an asbestos abatement
project?
A) Completion of a 16-hour asbestos awareness course B) Training to identify existing asbestos
hazards and authority to take prompt corrective measures, including stopping work C) A
bachelor's degree in industrial hygiene D) Ten years of experience in construction management
[CORRECT: B]
Rationale: Per OSHA 29 CFR 1926.1101(b), the Competent Person must be trained to identify
existing asbestos hazards in the workplace and must possess the authority to take prompt
corrective measures, including the authority to stop work. This is a functional definition based
on training and authority, not solely on education or experience. The precise regulatory factor is
ensuring on-site authority to immediately address hazards.
Question 4 (SATA) Which actions may the OSHA "Competent Person" take on an asbestos
abatement site? (Select all that apply)
A) Issue a stop-work order when asbestos fiber levels exceed the PEL B) Require workers to use
additional respiratory protection C) Authorize the use of dry removal methods to expedite the
project D) Inspect the negative pressure enclosure daily for integrity E) Dismiss workers who
violate safety protocols without documentation F) Require additional wetting of ACM if visible
emissions are observed
[CORRECT: A, B, D, F]
Rationale: Per OSHA 29 CFR 1926.1101(b) and (f), the Competent Person may: issue stop-work
orders (A), require additional PPE (B), inspect enclosures (D), and require additional wetting (F).
Dry removal methods (C) are prohibited under OSHA. Dismissing workers without
documentation (E) violates labor law and due process. The precise regulatory factor is that the
Competent Person's authority is bounded by OSHA standards and labor regulations.
Question 5 (True/False) The Competent Person under OSHA 1926.1101 must be present on-site
at all times during Class I asbestos work.
A) True B) False
[CORRECT: A]
Rationale: Per OSHA 29 CFR 1926.1101(f), the Competent Person must inspect job sites at least
once per shift during Class I asbestos work and must be readily available during all work
, operations. For Class I work, on-site presence is required to ensure immediate response to
hazards. The precise regulatory factor is ensuring continuous oversight of the highest-risk
asbestos operations.
Sub-Topic: ACM Definition (>1% by PLM) (2 Questions)
Question 6 (Multiple Choice) Under EPA and OSHA regulations, material is classified as
"Asbestos-Containing Material" (ACM) if it contains more than:
A) 0.1% asbestos by weight B) 1% asbestos by weight as determined by Polarized Light
Microscopy (PLM) C) 5% asbestos by weight D) 10% asbestos by weight
[CORRECT: B]
Rationale: Per EPA NESHAP (40 CFR 61.141) and OSHA 1926.1101(b), ACM is defined as material
containing more than 1% asbestos by weight as determined by Polarized Light Microscopy
(PLM) using EPA Method 600/R-93/116. This threshold distinguishes regulated ACM from trace
contamination. The precise regulatory factor is establishing a consistent analytical standard for
regulatory enforcement.
Question 7 (True/False) If bulk sample analysis by PLM shows 0.8% asbestos content, the
material is considered "Asbestos-Containing Material" under OSHA and must be handled using
full abatement protocols.
A) True B) False
[CORRECT: B]
Rationale: Per EPA NESHAP and OSHA 1926.1101(b), the regulatory threshold for ACM
classification is greater than 1% asbestos by PLM analysis. A result of 0.8% falls below this
threshold and is classified as "not ACM" for regulatory purposes, though it may still be handled
with caution. The precise regulatory factor is that the 1% threshold is the definitive cutoff for
mandatory abatement procedures.
Sub-Topic: NYS Industrial Code Rule 56 Floor-Buffing Variance (3 Questions)
Question 8 (Multiple Choice) Under New York State Industrial Code Rule 56, which condition
must be met to obtain a variance for using a floor-buffing machine on asbestos-containing floor
tile?
