Read the first 7 Hazardous Waste Management flashcards as text

  1. Under DOT regulations (49 CFR), which hazard class covers flammable liquids when shipped as hazardous materials?

    Answer: Class 3

    DOT Class 3 covers flammable liquids with a flash point at or below 60°C (140°F).

  2. What OSHA standard requires employers to train workers on hazardous chemicals in the workplace and provide Safety Data Sheets?

    Answer: 29 CFR 1910.1200 (Hazard Communication)

    OSHA's Hazard Communication Standard (HazCom/GHS) requires SDS access and employee training on chemical hazards.

  3. Which OSHA standard specifically governs worker health and safety during hazardous waste operations and emergency response activities?

    Answer: 29 CFR 1910.120 (HAZWOPER)

    HAZWOPER (29 CFR 1910.120) sets training, PPE, medical surveillance, and site safety plan requirements for hazardous waste workers.

  4. Under HAZWOPER, how many hours of initial training are required for workers who will be on-site during hazardous waste operations (not just occasional visitors)?

    Answer: 40 hours

    General site workers involved in hazardous waste operations must complete 40 hours of initial off-site training plus 3 days of supervised field experience.

  5. A waste passes the TCLP for arsenic at 3.5 mg/L. The regulatory threshold is 5.0 mg/L. What is the correct determination?

    Answer: The waste is not hazardous by toxicity characteristic for arsenic

    A TCLP result below the regulatory threshold (5.0 mg/L for arsenic) means the waste does not exhibit the toxicity characteristic for that constituent.

  6. Which EPA program addresses cleanup of abandoned or uncontrolled hazardous waste sites using Superfund money?

    Answer: CERCLA/Superfund

    CERCLA (Superfund) provides EPA authority and funding to clean up abandoned hazardous substance sites posing threats to public health.

  7. What is the primary advantage of using a permitted hazardous waste incinerator over a landfill for certain wastes?

    Answer: Destruction of organic hazardous constituents rather than containment

    Incineration at high temperatures destroys organic hazardous constituents, whereas landfills only contain them.
