Study Notes

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.
