Read the first 7 Storage flashcards as text

  1. Under 40 CFR Part 264, what is the maximum time a large quantity generator (LQG) may accumulate hazardous waste on-site without a storage permit?

    Answer: 90 days

    LQGs may accumulate hazardous waste on-site for up to 90 days without a RCRA storage permit under 40 CFR 262.17.

  2. Which NFPA standard specifically addresses the storage of flammable and combustible liquids in buildings and other structures?

    Answer: NFPA 30

    NFPA 30 is the Flammable and Combustible Liquids Code, which governs their storage in buildings and tanks.

  3. A satellite accumulation area (SAA) under RCRA allows accumulation of hazardous waste at or near the point of generation with a maximum container limit of:

    Answer: 55 gallons of hazardous waste or 1 quart of acutely hazardous waste

    SAAs are limited to 55 gallons of hazardous waste or 1 quart of acute hazardous waste per 40 CFR 262.15.

  4. When storing incompatible hazardous chemicals, what is the primary hazard that separation is intended to prevent?

    Answer: Dangerous reactions such as fire, explosion, or toxic gas release

    Separating incompatible chemicals prevents violent reactions including fires, explosions, and generation of toxic gases.

  5. Under DOT regulations, which class of placards is required on a transport vehicle carrying hazardous materials in storage awaiting shipment?

    Answer: Placards are only required once materials are loaded onto a vehicle

    DOT placarding requirements apply to vehicles during transport; once materials are unloaded into storage, transport placarding rules no longer apply.

  6. What does the term 'secondary containment' mean in the context of hazardous materials storage?

    Answer: A containment system designed to capture releases from primary containers or tanks

    Secondary containment is a system (such as a dike or berm) that captures spills or leaks from the primary storage container to prevent environmental release.

  7. OSHA's Process Safety Management (PSM) standard (29 CFR 1910.119) requires facilities to conduct a Process Hazard Analysis (PHA) when they store highly hazardous chemicals above:

    Answer: Threshold quantities specified in Appendix A of the standard

    PSM applicability is triggered when a highly hazardous chemical is present above the threshold quantity listed in 29 CFR 1910.119 Appendix A.
