CSST REVIEW EXAMS MAIN QUESTIONS AND
ANSWERS SURE A+
✔✔what is the minimum amount of liters for a test (only clearance) of method 7402? -
✔✔1,199 liters (clearance)
✔✔What areas does an AHERA inspection cover? - ✔✔interior of buildings (where kids
have walked), covered walkways or exterior portico, roofs (HVAC systems)
✔✔who can do an AHERA inspection? - ✔✔an accredited EPA inspector
✔✔What happens in the AHERA inspection process? - ✔✔identification of asbestos-
containing building material (ACBM), identification of homogoneous areas of suspect
ACBM (homogoneous being described as same color and texture and is identified on a
per-building basis)
✔✔How do you determine if a material is friable or non-friable? - ✔✔touch the material
to determine its friability
✔✔what materials are friable due to the manufacturing process? - ✔✔acoustical ceiling
spray, calcium/magnesium silicate ACM pipe insulation, and drywall/gypsum board
✔✔What materials are friable due to the application process? - ✔✔fire proofing on the
steel structure of a building and acoustical spray-on ceiling / wall plasters
✔✔what materials are usually considered non-friable? - ✔✔vinyl asbestos floor tile,
mastics, asphalt saturated roofing procedures (not included in AHERA), cement
asbestos products (transite)
✔✔What constitutes an AHERA re-inspection process? - ✔✔visual re-inspect and re-
assess the condition of all friable known or assumed ACM, visually inspect all materials
previously considered non-friable ACBM and touch the material to determine if it has
, become friable, identify any homogenous areas of these materials that have become
friable since the last inspection, for each homogenous area of newly friable material that
was assumed to contain asbestos-the inspector may collect samples in accordance with
AHERA regualtions, for all newly friable material sampled and proven to be ACM or
newly friable ACBM assuemd to be asbestos-containing-the inspector must conduct a
risk assessment in accordance with the AHERA regualtions, reassess all previously
identified materials whether sampled or presumed
✔✔When must all assessments be given to the LEA (Local Eductaion Agencies) by? -
✔✔within 30 days of the inspection
✔✔What is a z test? - ✔✔It was an AHERA method that is not longer practiced. It takes
the asbestos containing material and an acid, mixes them together and dilutes the
material or dust so that only the asbestos fibers are present and the end-result
determines the asbestos content by weight.
✔✔How long must exposure measurement records be kept by the employer? - ✔✔at
least 30 years
✔✔How long must medical surveillance records be kept by the employer? - ✔✔For the
term of the employment plus 30 years
✔✔How long must training records be kept by the employer? - ✔✔1 year
✔✔I Beam= - ✔✔web + flange + over spray x number of beams x length (always 2
webs and 3 flanges)
✔✔Protection Factor (PF)= - ✔✔Co/Ci (Co is concentration inside mask/Ci is
concentration outside mask)
✔✔TWA (Time-weighted average)= - ✔✔[C1(T1)+C2(T2)+C3(T3)+....]/480 minutes or 8
hours - where C is concentration and T is time (minutes)
✔✔L*W*H - ✔✔Length * Width * Height
✔✔Pipe square footage= - ✔✔2πR*L
✔✔Circular Tank Square footage= - ✔✔(2πR^2)+(2πR*L)
✔✔Scaffolding= - ✔✔4 feet * base dimension
✔✔When do you need guard rails for scaffolding? - ✔✔Above 6 feet
