    • Portable Fire Extinguisher: Hand-held or wheeled device expelling agents under pressure to extinguish fires.
    • Rechargeable Fire Extinguisher: Maintains full service with features like internal inspections and hydrostatic testing.
    • Self-Expelling Fire Extinguisher: Contains agents that can expel themselves due to sufficient vapor pressure.
    • Stored-Pressure Fire Extinguisher: Both agent and expellant gas in one container, includes a pressure indicator.
    • Water Mist Fire Extinguisher: Employs distilled de-ionized water sprayed as a fine mist for fire suppression.
    • Water-Type Fire Extinguisher: Contains water or foaming agents, including AFFF and wet chemicals.
    • Wheeled Fire Extinguisher: Portable unit on wheels for easy transport by a single person.

    Identification of Contents

    • Labels must include the product name as per the Material Safety Data Sheet (MSDS).
    • Hazardous material identification must comply with HMIS or GHS.
    • Information on hazardous substances over 1.0% and specific chemicals over 5.0% must be listed.
    • Must include hazard details based on MSDS and contact information for the manufacturer or service agency.

    Obsolete Fire Extinguishers

    • Specific types of extinguishers must be removed from service, including:
      • Soda Acid and Chemical foam extinquishers (non-film forming).
      • Carbon tetrachloride, Methyl bromide, and chlorobromomethane extinguishers.
