TDSHS Asbestos Inspector Exam practice questions and
answers 2023/2024
Per AHERA, management plan includes:
complete record of inspection, including construction plans, exact locales of ACBM,
assessment of physical condition of ACBM
moderate disturbance classification of disturbance factors
ACBM which shows any one of the following characteristics:
accessible, subject to vibration, or subject to air erosion; ACBM on corridor walls, a
ceiling underneath a gym, or in an elevator shaft
elements of asbestos hazard
conditions of asbestos; potential for disturbance (occupant activity, air movement);
number of people exposed; duration of exposure
PCM is for air
phase contrast microscopy
3 types of building materials defined by the USEPA under AHERA
1. Surfacing Materials - material in a school bldg that is sprayed-on, troweled-on, or
otherwise applied to materials
2. Thermal System Insulation - material in a school bldg, applied to pipes, fittings,
boilers, breeching, tanks, ducts, etc...
3. Miscellaneous ACM - interior bldg material on structural components, structural
members/fixtures, such as floor & ceiling tiles, & does not include surfacing material or
thermal insulation
advantages & disadvantages of enclosure
Adv: reduces exposure in the area outside the enclosure, initial costs may be lower than
removal, material replacement not necessary
Disadv: Asbestos source remains, fiber release continues behind enclosure, access to
enclosure must be controlled, periodic re-inspection required, maintenance of enclosure
necessary, long-term costs could be higher than removal
Physical properties of asbestos
chemical resistance (particularly to acids); bacterial resistance; in-combustibility;
thermal insulating ability; electrical insulating ability; mechanical strength; flexibility;
good friction & wear characteristics
definition of a hazard assessment
application of systematic method to rank hazards & determine appropriate corrective
actions, as judged by mgmt planner
characteristics of homogeneous sampling area
friable material, apparently identical, applied/installed at same time
elements of sample area diagram of a bldg
ID#; description of sample area; dimensions & drawing scale; name & address of bldg;
inspectors name; date of inspection; preparers name, date of drawings, purpose of
sample quality assurance; standardizes collection & handling method; specifies
analytical instrumentation
define inspector
, an EPA accredited person with training as per AHERA (40 CFR 763) & appropriate
experience
define competent person
OSHA - a person who is capable of identifying existing asbestos hazards in the
workplace & who has the authority to take corrective action
define PEL
OSHA - permissible exposure limit; means a level of airborne asbestos above which no
employee shall be exposed. the PEL is 0.1 f/cc of air as an 8 hr TWA
Inspector faces 3 areas of potential liability
contractual (insufficient # of samples specified); tort (legal wrong); governmental (non-
compliance w/federal or state regulations)
Subpart E Inspection
intended to satisfy requirements of Part III of 40 CFR Part 763 subpart E: ACM in
schools
minimum # of samples surfacing materials (K-12 schools)
<1000 sq ft - 3; >1000 but <5000 sq ft - 5; >5000 sq ft - 7
in a commercial bldg, you do NOT Have to be licensed to collect material
samples, per State of Texas
TDSHS - license requirements commercial bldgs; EPA/OSHA - worker protection;
AHERA - school requirements
Define serpentine types of asbestos
Chrysotile
define amphibole types of asbestos
amosite, crocidolite, anthophyllite, tremolite, actinolite
describe hazard assessment
involves analysis of the factors contributing to the actual or potential exposure of
building occupants to a hazardous substance.
describe prioritization
refers to the ordering or ranking of items in a list, in this case, determining appropriate
response actions based on the results of the hazard assessment
All ACM must be disposed of at an approved landfill in accordance with the
following provisions:
no visible emissions can be discharged to the outside air during collection, packaging,
transportation, or deposition of ACM
ACM must be wet or mixed with water & sealed in a leak tight container while wet
containers must be labeled per OSHA-specified labels
4 areas of federal regulations designed to control asbestos in bldgs
AHERA (Asbestos Hazard Emergency Response Act); NESHAPS (National Emission
Standards for Hazardous Air Pollutants); OSHA Asbestos Standard; EPA Worker
Protection Rule
3 ways to inform building occupants of ACM
distributing notices, posting signs, holding awareness/info sessions
purpose of a written plan
owners intent to control ACM while in remains in the bldg
describe hazard assessment factors
