Read the first 7 Facility Operations with Hazmat flashcards as text

  1. Under EPA's Risk Management Program (RMP) rule (40 CFR Part 68), a Program 3 process requires which of the following elements NOT required for Program 2?

    Answer: Process Hazard Analysis using a specific OSHA PSM methodology

    Program 3 requires a full PHA using OSHA PSM-listed methodologies (HAZOP, fault tree, etc.), whereas Program 2 allows simpler hazard reviews.

  2. A facility's waste characterization shows a liquid waste with pH 2.1. Under 40 CFR 261.22, this waste is classified as hazardous due to which characteristic?

    Answer: Corrosivity

    A liquid with pH ≤ 2 or ≥ 12.5 exhibits the RCRA corrosivity characteristic.

  3. When labeling an acute hazardous waste container at a large quantity generator facility, what is the maximum allowable accumulation time before the container must be moved to an approved storage area?

    Answer: 1 day

    Acute hazardous wastes (P-listed) must be moved from satellite accumulation areas to the central storage area within 1 day of reaching the container limit.

  4. A facility manager is reviewing a chemical's SDS and notes a vapor density of 1.8 (air = 1.0). This physical property indicates that the vapor will most likely do what in the facility?

    Answer: Sink and accumulate in low-lying areas and confined spaces

    Vapors with density greater than 1.0 are heavier than air and will settle in pits, trenches, and floor-level confined spaces.

  5. Under OSHA 29 CFR 1910.147 (Lockout/Tagout), before performing maintenance on a hazardous chemical pipeline at a facility, an employee must verify zero-energy state by:

    Answer: Testing the equipment to confirm that hazardous energy has been released or blocked

    Verification of zero-energy state requires actually testing the equipment—not just observing valve position—to confirm isolation is effective.

  6. A facility is required to submit a Tier II report under EPCRA Section 312. What is the annual reporting deadline for Tier II submissions?

    Answer: March 1

    Tier II emergency and hazardous chemical inventory reports are due to SERC, LEPC, and local fire departments by March 1 each year.

  7. Which of the following best describes the purpose of a facility's written Chemical Hygiene Plan (CHP) required by OSHA 29 CFR 1910.1450?

    Answer: To establish work practices, exposure controls, and procedures for protecting laboratory workers from hazardous chemicals

    The CHP is an OSHA-required written program for laboratories specifying engineering controls, PPE, and procedures to protect workers from chemical exposures.
