- 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.
Define Hazardous Waste
- 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.
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.
State the purpose and information contained on
the Material Safety Data Sheet (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.
What are the 6 categories of HM?
- Flammable or combustible materials, b. Toxic materials, c. Corrosive materials
- (including acids and bases), d. Oxidizing materials, e. Aerosol containers, f.
- Compressed gases
Explain the general procedures to be followed
when a HM/HW spill is discovered.
- 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
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
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
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
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.
Discuss the purpose of the HM Authorized Use
- 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.
