Study Notes
Hazardous Materials (HM) and Hazardous Waste (HW)
- Hazardous Material (HM): Any material that, due to its quantity, concentration, or properties, poses a substantial risk to human health or the environment if mishandled, released intentionally, or spilled accidentally.
- Hazardous Waste (HW): Any discarded material (solid, liquid, or gas) that meets the HM definition or is designated as hazardous waste by the Environmental Protection Agency (EPA) or a state authority. Ship policy is that ships do not generate HW.
Categories of Hazardous Materials
- Flammable/Combustible Materials
- Aerosol Containers
- Toxic Materials
- Corrosive Materials (acids and bases)
- Oxidizing Materials
- Compressed Gases
Incompatible Materials
- Certain materials, typically safe individually, can become hazardous when in contact or close proximity.
- Example: Oil-based products and Liquid Oxygen (LOX); Chemical conversion coatings and acids or combustibles (like paint, naphtha). HM in excess of a ship's needs.
HM/HW Spill Procedures
- Discovery: Spills or potential spills may be found through routine inspections, detection devices (fire alarms, oxygen deficiency detectors), or normal operations.
- Immediate Reporting: Any HM/HW spill or potential spill must be immediately reported verbally to supervisors and the Officer of the Deck (OOD) /Command Duty Officer (CDO).
- Crew Restrictions: Crewmembers should not investigate the spill.
- Reporting Information (if possible):
- Time of discovery
- Location
- Spilled material's identity
- Material's behavior (reactions observed)
- Spill source (container, tank)
- Personnel near the spill (names, departments)
- Spill volume
- Anticipated movement (e.g., from midship to galley)
- Labeling/placarding information (from the container only after exposure is eliminated)
Personal Protective Equipment (PPE) for HM/HW Handling
- Eye Protection
- Respiratory Devices
- Gloves
- Apron
- Coveralls
- Rubber Boots
Underway and Import Discharge Limitations
- Trash/Garbage (non-plastics): Pulped/comminuted (3-25) direct discharge permitted, exceeding 25 unsuitable for direct discharge.
- Plastic: No discharge permitted.
- Sewage: Discharge beyond 3 nautical miles.
- Oily Waste: Discharge beyond 12 nautical miles if equipped with an Oil Content Monitor (OCM) <15ppm oil, or 50 nautical miles if equipped with an Oil Water Separator (OWS) and no OCM.
- Paint/Mineral Spirits: No discharge permitted.
