A Home Fire Extinguisher Buying Guide

2/9/2022 (Permalink)

Extinguishers are classified in accordance with standard 10 set by the National Fire Protection Agency.

Every home should have a fire extinguisher to suppress minor fires. This buying guide identifies the main classes of fire extinguishers and explains why a multi-class or rechargeable extinguisher may be ideal for home use.

Extinguisher Classes

Extinguishers are classified in accordance with standard 10 set by the National Fire Protection Agency. Suppressants are selected for effectiveness and safety:

• Class A extinguishers contain monoammonium phosphate and work on ordinary combustibles
• Class B extinguishers contain monoammonium phosphate and sodium bicarbonate and work on flammable liquids or gases, but not cooking oils or grease
• Class C extinguishers contain monoammonium phosphate and sodium bicarbonate and work on appliances or powered electrical equipment
• Class D extinguishers contain sodium chloride or copper powder and work on combustible metals
• Class K extinguishers contain potassium compounds and work on cooking oils and grease

The most common home fire extinguishers are classes A, B, and C. Underwriters Laboratories assigns the number that precedes these letters and indicates the effectiveness of a fire extinguisher. A 4-A extinguisher is more effective than a 2-A extinguisher.

Multi-Class Extinguishers

Some extinguishers are rated for multiple classes. Homeowners may prefer a multi-class extinguisher to promote comprehensive fire preparedness. Determine the most likely fire risks and purchase an extinguisher rated for all of these classes.

Disposable or Rechargeable

Disposable extinguishers have plastic valves and must be replaced after a single-use. Rechargeable extinguishers have durable metal valves and cost more upfront. Suppressant refills are more affordable than purchasing a new disposable extinguisher.

All of these factors are important to consider when purchasing home fire safety equipment for a residence in Smith Springs, TN. Homeowners may want to install a different class of fire extinguisher in the kitchen, garage, laundry room, and other areas based on the most likely fire risks. If a fire results in property damage, contact a mitigation and restoration company.
