ATP Safety Standards & Environmental Compliance 3 — Questions and Answers
Question 1: Under EPA's Risk Management Program (RMP) Rule (40 CFR Part 68), which Program level applies to processes with the highest accident history or worst-case consequences that require a full prevention program and emergency response plan?
- Program 1
- Program 2
- Program 3 (Correct answer)
- Program 4
Correct answer: Program 3
Program 3 applies to processes in specified OSHA industries or with complex hazards, requiring full prevention programs, emergency response plans, and accident investigation procedures.
Question 2: Which OSHA standard requires employers to develop a written energy control (lockout/tagout) program and establish machine-specific procedures?
- 29 CFR 1910.146
- 29 CFR 1910.147 (Correct answer)
- 29 CFR 1910.119
- 29 CFR 1910.178
Correct answer: 29 CFR 1910.147
29 CFR 1910.147, the Control of Hazardous Energy standard, requires written LOTO programs and equipment-specific procedures to protect workers during servicing and maintenance.
Question 3: A technician is exposed to a chemical with a permissible exposure limit (PEL) of 50 ppm as an 8-hour TWA. A breathing zone sample shows 65 ppm averaged over the shift. What is the correct regulatory conclusion?
- Compliant because the reading is within 25% of the PEL
- Non-compliant; the employer must implement controls to reduce exposure below the PEL (Correct answer)
- Compliant because TWA measurements have a ±20% margin of error
- Non-compliant only if two consecutive samples exceed the PEL
Correct answer: Non-compliant; the employer must implement controls to reduce exposure below the PEL
Any TWA exposure exceeding the OSHA PEL is a violation, requiring the employer to implement feasible engineering or administrative controls to reduce exposure.
Question 4: Which environmental regulation requires large quantity generators (LQGs) of hazardous waste to submit a biennial report to the EPA?
- CERCLA Section 103
- RCRA Subtitle C (40 CFR Part 262) (Correct answer)
- TSCA Section 4
- EPCRA Section 311
Correct answer: RCRA Subtitle C (40 CFR Part 262)
Under RCRA Subtitle C (40 CFR Part 262), LQGs must submit biennial hazardous waste reports to EPA covering waste generation, management, and shipment data.
Question 5: Which ANSI/ISEA standard governs the performance requirements for high-visibility safety apparel (HVSA) worn by workers near vehicle traffic?
- ANSI/ISEA 107 (Correct answer)
- ANSI/ISEA 105
- ANSI Z87.1
- ANSI Z89.1
Correct answer: ANSI/ISEA 107
ANSI/ISEA 107 establishes performance requirements for high-visibility safety apparel, classifying garments by visibility class based on background and retroreflective material areas.
Question 6: When conducting a confined space entry under OSHA 29 CFR 1910.146, which atmospheric condition ALONE classifies a space as immediately dangerous to life or health (IDLH)?
- Oxygen level of 19.4%
- Flammable gas concentration at 15% of the LEL
- Carbon monoxide at 1,200 ppm (Correct answer)
- Hydrogen sulfide at 10 ppm
Correct answer: Carbon monoxide at 1,200 ppm
NIOSH defines CO IDLH at 1,200 ppm; this concentration can cause death or irreversible health effects and constitutes an IDLH atmosphere requiring immediate evacuation.
Question 7: Under the EPA's Spill Prevention, Control, and Countermeasure (SPCC) rule, which type of facility is primarily regulated?
- Facilities generating more than 1 kg of acutely hazardous waste per month
- Facilities with oil storage capacity above certain thresholds that could reasonably discharge to navigable waters (Correct answer)
- Facilities releasing more than 10,000 lbs of a TRI chemical annually
- Facilities using ozone-depleting substances above de minimis quantities
Correct answer: Facilities with oil storage capacity above certain thresholds that could reasonably discharge to navigable waters
The SPCC rule (40 CFR Part 112) applies to facilities with aggregate aboveground oil storage above 1,320 gallons (or 42,000 gallons underground) that could reasonably discharge oil to navigable waters.
