Hazardous Material Waste

Hazardous Material(HM)/ Hazardous Waste (HW) Fundamentals
Show Answers:

  1. Define Hazardous Material
    • Any
    • material that, because of its quantity, concentration, or physical or chemical
    • characteristics, may pose a substantial hazard to human health or the
    • environment when purposefully released or accidentally spilled.
  2. Define Hazardous Waste
    • Any
    • discarded material (liquid, solid, or gas) which meets the definition of HM
    • and/or is designated as a hazardous waste by the Environmental Protection
    • Agency or a State authority.
  3. Discuss HM storage and inspection requirements
    • Stowage locations shall be inspected weekly and quarterly, inspect for
    • tightness of closure, corrosion, leakage, improper or inadequate labeling, and
    • expired shelf-life.
  4. State the purpose and information contained on
    the Material Safety Data Sheet (MSDS).
    • MSDS
    • are technical bulletins containing information about materials, such as
    • composition, chemical, and physical characteristics, health and safety hazards,
    • and precautions for safe handling and use. They are located with the HM/HW
    • Coordinator at Medical, Supply Officer, Work Center, and the HM container.
  5. What are the 6 categories of HM?
    • a.
    • Flammable or combustible materials, b. Toxic materials, c. Corrosive materials
    • (including acids and bases), d. Oxidizing materials, e. Aerosol containers, f.
    • Compressed gases
  6. Explain the general procedures to be followed
    when a HM/HW spill is discovered.
    • Because
    • of the hazardous nature of many materials used aboard ships, only trained
    • personnel shall respond to a hazardous material (HM) spill. Personnel shall be
    • trained by division officers or supervisory personnel to clean up small spills
    • of HM. Appropriate MSDS sheets shall be used to conduct training. Spill
    • response procedures are:
    • a. Discovery b. Notification c. Initiation of action d. Evaluation e. Containment f. Damage Control g. Dispersion of gases/vapors h. cleanup and decontamination i. Disposal j. Certification for reentry k. Follow-up reports
  7. State the personal protection equipment required
    when handling HM/HW.
    • Verify all PPE against the MSDS, 5100.19D, or as a last resort the HMUG.
    • At a minimum you must use eye protection, respiratory protection devices, and
    • gloves.
  8. Discuss the disposal limitations for the
    • For all disposal limitations refer to the Environmental and Natural
    • Resources Program Manual, OPNAVINST 5090.1B, Appendix L.
    • a. Adhesives: Containerize for shore disposal.
    • b. Grease: Oily solid materials
    • such as contaminated rags, absorbents, and oil filters must be containerized
    • for shore disposal.
    • c. Hydraulic fluids and Waste Oils: If used or contaminated, dispose of
    • through the oily waste separator. If in a non-resealable container, dispose of
    • in the same manner. Keep synthetic fluids separate from other types of fluids.
    • d. Fuels: Keep synthetic and petroleum lubricants separate.
    • e. Paint/paint
    • thinners: Containerize for shore disposal
  9. Describe required training for all hands with
    respect to the HM/HW program.
    • There are two types of required training. Initial training given in
    • Indoc, and Annually. Training shall include:
    • a. Types of HM in their work area and aboard ship.
    • b. What HMs are and how they are disposed of.
    • c. How to read and interpret hazard warning labels.
    • d. What an MSDS is, how to read it, and where a copy is available to
    • review. General information on HM handling, stowage, use, and disposal.
    • e. Protective measures when handling HM.
    • f. Emergency
    • procedures.
  10. Describe the purpose of secondary labeling of
    HM when removed from the original container.
    • Use only approved containers, ensure that existing precautionary labeling
    • is retained and that subsequent containers are marked with appropriate
    • precautionary labeling.
  11. Discuss the purpose of the HM Authorized Use
    List (AUL).
    • A
    • current inventory of HM, chemical substances, or components known or suspected
    • to contain HM used for local acquisition and use. Local work centers or codes
    • should maintain a current inventory of items authorized for local use and keep it current.
