NFPA 10 Fire Extinguisher Definitions

Fire Extinguisher Types and Definitions

• Cartridge/Cylinder-Operated Fire Extinguisher: Uses an expellant gas stored separately from the agent.
• Nonchargable Fire Extinguisher: Designed for one-time use; cannot be recharged or restored.
• 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.

Standards for Specific Fire Extinguishers

• Carbon Dioxide Fire Extinguishers: Complies with ANSI/UL 154 and CAN/ULC S503 standards.
• Dry Chemical Fire Extinguisher: Follows ANSI/UL 299 and CAN/ULC S504 standards.
• Water Type Fire Extinguisher: Aligned with ANSI/UL 626 and CAN/ULC S507 standards.
• Halon Fire Extinguisher: Meets CAN/ULC S512 standards for halogenated agents.
• Film-Forming Fire Extinguisher: Adheres to ANSI/UL 8 and CAN/ULC S554 standards.
• Halocarbon Fire Extinguisher: Complies with ANSI/UL 2129 and CAN/ULC S566 standards.

Marking and Labeling Requirements

• Fire extinguishers must display identification from listing and labeling organizations.
• Product categorization indicating the extinguisher type is required.
• Classifications (A, B, C, D, K) need to be clearly marked on the extinguisher.
• Standards for performance and fire testing met by the extinguisher must be included.

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.
  • Cartridge-operated water and loaded stream extinguishers.
  • Certain old models of carbon dioxide extinguishers with metal horns.
• Additional obsolete units include solid charge AFF extinguishers, pressurized water extinguishers before 1971, and any needing inversion to operate.
