1Under EPA NESHAP regulations (40 CFR Part 61 Subpart M), what is the minimum advance written notice required prior to beginning demolition on a facility containing regulated asbestos-containing material (RACM) above threshold amounts?

A.5 calendar days

B.10 working days

C.14 calendar days

D.30 working days

Explanation: EPA NESHAP rules require written notification to the EPA or delegated state/local air quality agency at least 10 working days before starting demolition activities on structures exceeding the threshold quantities of RACM (260 linear feet on pipes, 160 square feet on other facility components, or 35 cubic feet).

2A demolition contractor encounters old exterior transite wall panels that have become severely weathered and easily crumble into powder when crushed by hand pressure. How is this material classified under EPA guidelines?

A.Category I non-friable asbestos-containing material

B.Category II non-friable asbestos-containing material that has remained non-friable

C.Regulated friable asbestos-containing material (RACM)

D.Non-regulated construction debris

Explanation: When non-friable asbestos-containing material (such as Category II transite panels) becomes crumbled, pulverized, or reduced to powder by hand pressure or mechanical impact, it becomes friable and is classified as Regulated Asbestos-Containing Material (RACM).

3According to OSHA 29 CFR 1926.62 (Lead in Construction), what is the Permissible Exposure Limit (PEL) for airborne lead averaged over an 8-hour work shift?

A.50 µg/m³

B.30 µg/m³

C.100 µg/m³

D.15 µg/m³

Explanation: OSHA's Lead in Construction standard sets the Permissible Exposure Limit (PEL) for lead at 50 micrograms per cubic meter of air (50 µg/m³) averaged over an 8-hour TWA. If exposures exceed this level, engineering controls, respiratory protection, and protective clothing are mandatory.

4During manual demolition of structural steel coated with lead-based primer, air monitoring indicates an 8-hour time-weighted average lead concentration of 35 µg/m³. What requirement is triggered under OSHA 1926.62?

A.Immediate shutdown of all work activities across the entire jobsite

B.Mandatory full-face supplied-air respirator usage for all workers regardless of duty

C.No action required since the concentration is below 50 µg/m³

D.Initiation of employee exposure monitoring, medical surveillance, and training because the level exceeds the Action Level

Explanation: The Action Level for lead under OSHA 1926.62 is 30 µg/m³ as an 8-hour TWA. Exceeding 30 µg/m³ (even though below the 50 µg/m³ PEL) mandates periodic air monitoring, biological medical surveillance (blood lead testing), and employee training.

5Before flame-cutting or demolishing an underground fuel storage tank (UST) removed from a demolition site, what Lower Explosive Limit (LEL) threshold must be verified with a calibrated combustible gas indicator?

A.Less than 25% LEL

B.Less than 10% LEL

C.Less than 50% LEL

D.Exactly 0% LEL with no oxygen present

Explanation: Standard industrial safety guidelines (API 2015 / OSHA 1926.850) require fuel tanks to be thoroughly cleaned, purged of flammable vapors, or inerted so that internal vapor concentrations test below 10% of the Lower Explosive Limit (LEL) prior to hot work or mechanical tearing.

6When salvaging electrical equipment from an industrial facility built in 1970 prior to wrecking, how must older oil-filled transformers and fluorescent lamp ballasts lacking 'No PCBs' labels be managed?

A.Crushed on site and disposed of in a standard C&D (construction and demolition) landfill

B.Burned on site in an open scrap pit to evaporate transformer fluids

C.Presumed to contain Polychlorinated Biphenyls (PCBs) and handled as regulated hazardous waste under TSCA

D.Drained into municipal storm drains prior to recycling steel casings

Explanation: Electrical equipment manufactured prior to 1979 without explicit 'No PCBs' labeling must be presumed to contain Polychlorinated Biphenyls (PCBs) under the Toxic Substances Control Act (TSCA) and disposed of at approved hazardous waste facilities.

7Under OSHA 29 CFR 1926.1153, what is the Permissible Exposure Limit (PEL) for Respirable Crystalline Silica during concrete hydraulic breaking and crushing?

A.50 µg/m³ as an 8-hour TWA

B.25 µg/m³ as an 8-hour TWA

C.100 µg/m³ as an 8-hour TWA

D.5 µg/m³ as an 8-hour TWA

Explanation: OSHA's Respirable Crystalline Silica standard for construction sets the PEL at 50 micrograms per cubic meter of air (50 µg/m³) calculated as an 8-hour time-weighted average (TWA).

8Which engineering control is primary and most effective for suppressing silica dust during mechanical demolition of reinforced concrete structures?

A.Increasing excavator engine RPM

B.Using compressed air blowers to clear dust from work areas

C.Operating heavy diesel exhaust fans in open outdoor areas

D.Continuous wet suppression using integrated water mist nozzles or hose sprayers

Explanation: Continuous application of water spray or wet suppression directly at the point of impact is the recognized primary engineering control under OSHA Table 1 to capture airborne respirable silica dust before it spreads.

9When transporting hazardous waste generated during commercial demolition within Arizona (such as lead paint chips or solvent sludge), what document must accompany the transport vehicle under ADEQ rules?

A.A standard commercial bill of lading with no environmental disclosures

B.A Uniform Hazardous Waste Manifest signed by the generator, transporter, and disposal facility

C.An informal handwritten inventory signed by the site foreman

D.A city building permit copy attached to the vehicle dashboard

Explanation: Under Arizona Department of Environmental Quality (ADEQ) and EPA regulations, regulated hazardous waste must be tracked from cradle to grave using a Uniform Hazardous Waste Manifest (EPA Form 8700-22).

10Which asbestos work classification applies under OSHA 1926.1101 to the removal of thermal system insulation (TSI) from steam pipes inside a structure prior to wrecking?

A.Class III asbestos work

B.Class IV asbestos work

C.Class I asbestos work

D.Class II asbestos work

Explanation: Class I asbestos work is defined by OSHA as activities involving the removal of thermal system insulation (TSI) and surfacing asbestos-containing material, representing the highest risk tier requiring negative pressure enclosures and strict decontamination protocols.
