NYS ASBESTOS INVESTIGATOR EXAM 200 ACTUAL
QUESTIONS AND CORRECT ANSWERS WITH RATIONALE
ALREADY GRADED A+
This comprehensive set of 200 unique multiple-choice questions covers the full
scope of the NYS Asbestos Investigator exam, including regulations (AHERA,
NESHAP, ICR 56, OSHA, NYC DEP Title 15), health effects, sampling
methodologies, laboratory analysis (PLM, PCM, TEM), friability
classifications, response actions, abatement oversight, decontamination, and
recordkeeping. Each question provides a distinct regulatory scenario,
definition, or procedural application with detailed rationale, ensuring
candidates understand both the correct answer and the underlying legal and
scientific reasoning. Topics range from ACM definitions and homogeneous
area sampling to clearance air monitoring and waste disposal, preparing
candidates thoroughly for certification and professional practice.
1. What is the primary purpose of the New York State Asbestos Investigator
certification?
A) To perform asbestos abatement and removal
B) To inspect buildings for asbestos-containing materials and conduct hazard
assessments
C) To design asbestos remediation projects
D) To dispose of asbestos waste
Answer: B
Rationale: An asbestos investigator's primary role is to check buildings for
asbestos-containing materials (ACM) and conduct hazard assessments for ACM.
This certification is distinct from abatement contractor or project designer
certifications .
2. Which federal regulation specifically requires asbestos surveys in schools and
public buildings?
A) NESHAP 61
B) AHERA (Asbestos Hazard Emergency Response Act)
C) OSHA 29 CFR 1926.1101
D) EPA Clean Air Act
Answer: B
, Rationale: AHERA mandates asbestos inspections, management plans, and
periodic surveillance in schools and public facilities. This is a fundamental
regulation that asbestos investigators must understand .
3. Under New York State Industrial Code Rule 56, what is the primary purpose of
a "Homogeneous Area" designation?
A) To identify areas where asbestos is present in mixed materials
B) To group materials of the same type, color, and texture for sampling
efficiency
C) To designate zones that require full abatement before any work begins
D) To indicate areas that are exempt from sampling because they are non-friable
Answer: B
Rationale: ICR 56 defines a Homogeneous Area (HA) as a region where
materials are uniform, allowing a single sample to represent the entire area. This
grouping reduces the number of required samples .
4. ACM is defined as any material containing more than what percentage of
asbestos by weight?
A) 0.5%
B) 1%
C) 2%
D) 5%
Answer: B
Rationale: Asbestos-Containing Material (ACM) is defined by regulation as any
material containing more than 1% asbestos by weight. This threshold determines
whether a material is subject to regulatory requirements .
5. When did the EPA asbestos guidance go into effect?
A) January 1, 1985
B) March 31, 1986
C) January 1, 1990
D) April 1, 1995
Answer: B
Rationale: The EPA guidance for asbestos-related activities went into effect on
March 31, 1986. This date is significant for understanding the timeline of
regulatory requirements .
6. What is the minimum number of bulk samples required for surfacing material
covering 1,000 square feet or less?
A) 1 sample
, B) 3 samples
C) 5 samples
D) 7 samples
Answer: B
Rationale: For surfacing material covering 1,000 square feet or less, at least 3
bulk samples must be taken. The number of required samples increases with the
size of the homogeneous area .
7. What is the minimum number of bulk samples required for surfacing material
covering 1,000 to 5,000 square feet?
A) 3 samples
B) 5 samples
C) 7 samples
D) 9 samples
Answer: B
Rationale: For surfacing material covering 1,000 to 5,000 square feet, at least 5
bulk samples must be taken. The sampling requirements are based on the square
footage of the homogeneous area .
8. What is the minimum number of bulk samples required for surfacing material
covering 5,000 square feet or more?
A) 5 samples
B) 7 samples
C) 9 samples
D) 10 samples
Answer: B
Rationale: For surfacing material covering 5,000 square feet or more, at least 7
bulk samples must be taken. More samples ensure adequate representation of the
material's asbestos content .
9. What is the recommended number of samples for surfacing material, regardless
of area size?
A) 3 samples
B) 5 samples
C) 7 samples
D) 9 samples
Answer: D
Rationale: The recommended practice is to take 9 samples of surfacing material
whenever possible, regardless of the area size. This provides the highest
confidence in determining asbestos content .
, 10. How many bulk samples of thermal system insulation should generally be
taken from each homogeneous area?
A) 1 sample
B) 3 samples
C) 5 samples
D) 7 samples
Answer: B
Rationale: Generally, at least 3 bulk samples of thermal system insulation should
be taken in a random manner from each homogeneous area. This ensures
representativeness of the insulation material .
11. When is it acceptable to take only 1 sample of thermal system insulation?
A) When the material is known to contain asbestos
B) When the material is a patch and is less than 6 linear feet
C) When the material is fiberglass
D) When the material is non-friable
Answer: B
Rationale: Only 1 sample of thermal insulation is required when the material is a
patch and is less than 6 linear feet. This exception is based on the limited size and
scope of the material .
12. When is sampling of thermal insulation NOT required?
A) When the insulation is covered by a protective barrier
B) When the insulation is in good condition
C) When the insulation is fiberglass
D) When the insulation is located in a school
Answer: C
Rationale: Fiberglass insulation does not need to be sampled for asbestos
because it is not an asbestos-containing material. Fiberglass is a distinct material
with different properties .
13. How many samples are required for miscellaneous building materials?
A) 1 sample
B) At least 2 samples
C) At least 3 samples
D) At least 5 samples
Answer: B
