1. The primary health risk from asbestos exposure is:
Asbestosis, lung cancer, and mesothelioma
Asbestos fibers can cause scarring, cancer, and mesothelioma when inhaled.
2. The permissible exposure limit (PEL) for asbestos set by OSHA is:
0.1 fibers per cubic centimeter of air (f/cc) as an 8-hour TWA
OSHA’s standard limits worker exposure to prevent long-term health effects.
3. A fiber is defined by OSHA as a particle longer than 5 micrometers with an
aspect ratio of at least:
3:1
The definition helps standardize exposure monitoring and risk assessment.
4. Which agency regulates asbestos abatement in Texas?
Texas Department of State Health Services (DSHS)
DSHS enforces state asbestos rules consistent with federal standards.
5. Asbestos-containing material (ACM) is legally defined as material
containing:
More than 1% asbestos
EPA regulations classify ACM at this threshold.
6. Friable asbestos-containing material means:
Material that can be crumbled, pulverized, or reduced to powder by hand
pressure
Friable ACM easily releases fibers into the air.
,7. Non-friable ACM that has become damaged is classified as:
Regulated Asbestos-Containing Material (RACM)
Damaged non-friable ACM poses the same risks as friable ACM.
8. Negative air pressure systems during abatement must maintain at least:
0.02 inches of water column pressure differential
This prevents asbestos fibers from escaping the work area.
9. The number of air changes per hour (ACH) recommended in a containment
is:
At least 4 ACH
Adequate air movement dilutes airborne fibers.
10.A HEPA filter is required to remove particles as small as:
0.3 microns with 99.97% efficiency
HEPA filters are essential in asbestos abatement equipment.
11.Which type of respirator is most commonly required for asbestos
abatement supervisors?
Half-face or full-face air-purifying respirator with P100 filters
Provides protection against airborne asbestos fibers.
12.A decontamination unit for workers must include at least:
Three chambers: clean room, shower, and equipment room
This ensures proper decontamination and prevents contamination spread.
13.Waste from asbestos abatement must be disposed of:
In leak-tight containers with asbestos warning labels
This prevents release of asbestos during transport and disposal.
14.OSHA requires air monitoring during asbestos abatement to:
Ensure worker exposure does not exceed the PEL
Monitoring is crucial to compliance and safety.
15.A "competent person" in asbestos work is defined as:
An individual trained and capable of identifying hazards and authorized to
, take corrective measures
The competent person ensures compliance and worker safety.
16.The primary method of controlling asbestos fiber release during abatement
is:
Wet methods (adequate wetting of ACM)
Keeps fibers from becoming airborne.
17.When an asbestos project exceeds 160 square feet or 260 linear feet, it is
classified as:
A regulated asbestos abatement project
Projects above these thresholds must follow strict federal and state rules.
18.Clearance air testing must be conducted using:
Phase Contrast Microscopy (PCM) or Transmission Electron Microscopy
(TEM)
Testing verifies that the area is safe for re-occupancy.
19.The required clearance level for final air monitoring in schools under AHERA
is:
0.01 fibers/cc or background equivalent
This ensures safety for building occupants.
20.The purpose of glovebags in asbestos abatement is:
To enclose pipe insulation for safe removal
They prevent fiber release while removing ACM from pipes.
21.The minimum number of negative air machines required in a containment
depends on:
Air changes per hour and volume of containment
Sufficient machines are needed to maintain negative pressure.
22.The Texas Asbestos Program requires supervisors to renew their license:
Every year
Annual renewal ensures continued competency and compliance.
