1. A permit for asbestos abatement activities in Texas must be obtained
from which entity prior to the start of work, unless a specific exemption
applies?
A. Texas Department of Insurance (TDI)
B. Texas Commission on Environmental Quality (TCEQ)
C. Texas Department of State Health Services (DSHS)
CORRECT ANSWER: C – Rationale: Under Texas Health and Safety
Code, Chapter 1954, the DSHS has jurisdiction over asbestos abatement
permitting, licensing, and worker protection. TCEQ handles waste
disposal, but DSHS oversees abatement permits.
D. Occupational Safety and Health Administration (OSHA)
2. In a Class I asbestos removal job, the supervisor is required to perform a
visual inspection for potential fiber release pathways at least:
A. Once per week
B. At the start of the shift each day
C. Before each work shift and after any change in work conditions
, CORRECT ANSWER: C – Rationale: 29 CFR 1926.1101 and Texas
DSHS rules require continuous surveillance; a competent person
(supervisor) must inspect before each shift and after any event that could
increase fiber release.
D. Only during initial setup
3. Which of the following is the minimum negative air pressure unit
(NAPU) requirement for a critical barrier that encloses a 2,000-square-
foot regulated area in Texas?
A. 1 NAPU per 500 square feet
B. 1 NAPU per 1,000 square feet, or as engineered to achieve 0.01
inches of water column negative pressure
CORRECT ANSWER: B – *Rationale: Texas DSHS rule §295.36
requires negative pressure of -0.01 to -0.02 inches WC; one NAPU per
1,000 sq. ft. is a general guide, but engineering control must verify
pressure differential.*
C. 2 NAPUs regardless of area
D. No minimum if HEPA vacuums are used
4. An asbestos abatement supervisor finds a tear in the glovebag during a
pipe removal. The FIRST action is:
A. Complete the pipe removal quickly
B. Patch the tear with duct tape
C. Stop work, evacuate the area, and repair or replace the glovebag
CORRECT ANSWER: C – Rationale: Supervisor must immediately
, halt operations to prevent fiber release, follow emergency procedures,
and ensure containment integrity before resuming.
D. Increase negative pressure
5. Which document must be posted at the decontamination enclosure
entrance for all Texas asbestos abatement projects regulated by DSHS?
A. The building’s original blueprints
B. The asbestos medical surveillance program notice
C. The warning sign required under 29 CFR 1926.1101(k) and
Texas DSHS rules
CORRECT ANSWER: C – Rationale: Warning signs (e.g., “DANGER
ASBESTOS CANCER AND LUNG DISEASE HAZARD”) must be posted
at each decontamination area entrance, consistent with federal and state
requirements.
D. The supervisor’s personal driver’s license
6. A homeowner requests asbestos testing before a renovation. Under
Texas law, who may collect bulk samples for analysis?
A. Any homeowner without training
B. Only a licensed asbestos consultant
C. A Texas-licensed asbestos abatement supervisor or a licensed
asbestos consultant
CORRECT ANSWER: C – *Rationale: Texas DSHS rules allow a
licensed asbestos abatement supervisor to collect bulk samples if they
have completed the required 8-hour sampling course or as part of
, supervisor training, but a consultant is also permitted. Homeowners
cannot sample for regulatory compliance.*
D. Any general contractor
7. During an outdoor asbestos abatement project, the supervisor must
ensure that all asbestos-containing material (ACM) is kept wet and
placed into:
A. Open dumpsters covered at end of day
B. Leak-tight containers with two properly sealed 6-mil polyethylene
bags or a single 6-mil bag and a rigid container
CORRECT ANSWER: B – *Rationale: 40 CFR Part 61 Subpart M
(NESHAP) and Texas rules require wetting and double-bagging or
equivalent sealed containers.*
C. Cardboard boxes
D. Any plastic bag without labeling
8. What is the maximum allowable airborne asbestos fiber concentration
inside a negative pressure enclosure during abatement, as measured by
phase contrast microscopy (PCM) for clearance?
A. 0.01 fibers/cc
B. 0.01 fibers/cc or less, but clearance requires TEM analysis for
schools—PCM not sufficient for final clearance in K-12 under
AHERA
CORRECT ANSWER: B – *Rationale: For most Texas projects, <0.01
f/cc PCM is acceptable for clearance; however, for K-12 schools,
