AERA Safety Standards & Environmental Compliance 3 — Questions and Answers
Question 1: Which document must accompany a shipment of hazardous waste from an engine rebuilding facility to a licensed disposal site?
- Bill of lading only
- Uniform Hazardous Waste Manifest (Correct answer)
- OSHA 300 log
- Material Safety Data Sheet alone
Correct answer: Uniform Hazardous Waste Manifest
A Uniform Hazardous Waste Manifest (EPA Form 8700-22) must accompany all hazardous waste shipments from generator to disposal facility per RCRA requirements.
Question 2: When degreasing engine blocks with chlorinated solvents, the primary air quality concern regulated under the Clean Air Act is:
- Carbon monoxide emissions
- Volatile Organic Compound (VOC) and HAP emissions (Correct answer)
- Particulate matter from metal shavings
- Nitrogen oxide from heated solvents
Correct answer: Volatile Organic Compound (VOC) and HAP emissions
Chlorinated solvents are Hazardous Air Pollutants (HAPs) and VOCs regulated under the Clean Air Act's National Emission Standards for Hazardous Air Pollutants (NESHAP).
Question 3: A worker in an engine machine shop is exposed to silica dust from valve seat grinding. The applicable OSHA permissible exposure limit (PEL) for respirable crystalline silica is:
- 0.05 mg/m³ as an 8-hour TWA (Correct answer)
- 0.5 mg/m³ as an 8-hour TWA
- 5.0 mg/m³ as an 8-hour TWA
- 0.005 mg/m³ as an 8-hour TWA
Correct answer: 0.05 mg/m³ as an 8-hour TWA
OSHA's silica standard (29 CFR 1910.1053) sets the PEL for respirable crystalline silica at 50 micrograms per cubic meter (0.05 mg/m³) as an 8-hour TWA.
Question 4: Under the EPA's Spill Prevention, Control, and Countermeasure (SPCC) rule, an engine rebuilding facility must develop a SPCC plan if its aboveground oil storage capacity exceeds:
- 275 gallons total
- 1,320 gallons total (Correct answer)
- 5,000 gallons total
- 10,000 gallons total
Correct answer: 1,320 gallons total
Facilities with aggregate aboveground oil storage capacity greater than 1,320 gallons (or underground storage over 42,000 gallons) must prepare a SPCC plan.
Question 5: Safety Data Sheets (SDS) must be readily accessible to employees during their work shift under which OSHA standard?
- 29 CFR 1910.132 (PPE standard)
- 29 CFR 1910.1200 (Hazard Communication Standard) (Correct answer)
- 29 CFR 1910.147 (LOTO standard)
- 29 CFR 1910.157 (fire extinguisher standard)
Correct answer: 29 CFR 1910.1200 (Hazard Communication Standard)
OSHA's Hazard Communication Standard (HazCom), 29 CFR 1910.1200, requires that SDS be immediately accessible to employees during their work shifts.
Question 6: Lead-containing engine components (such as old bearing shells) disposed of by an engine rebuilder may be exempt from RCRA hazardous waste rules if they qualify as:
- Universal waste under 40 CFR Part 273
- Scrap metal recycled by a legitimate recycler (Correct answer)
- Municipal solid waste going to a licensed landfill
- Conditionally exempt small quantity generator waste
Correct answer: Scrap metal recycled by a legitimate recycler
Scrap metal, including lead-containing engine parts destined for recycling, is exempt from RCRA hazardous waste regulations under the scrap metal recycling exclusion.
Question 7: Which personal protective equipment is specifically required when performing magnaflux (magnetic particle) inspection on engine components using wet fluorescent method?
- Steel-toed boots only
- UV-protective eyewear and chemical-resistant gloves (Correct answer)
- Full-face respirator and hearing protection
- Hard hat and reflective vest
Correct answer: UV-protective eyewear and chemical-resistant gloves
Wet fluorescent magnetic particle inspection requires UV-protective eyewear to protect against black light exposure and chemical-resistant gloves to handle the carrier fluid.
