Kidde BC Fire Extinguishers

Kidde BC Fire Extinguishers

Kidde BC fire extinguishers are designed for locations where flammable liquids and energized electrical equipment are the primary fire hazards. Unlike multi-purpose ABC extinguishers, BC models concentrate on Class B and Class C protection and are commonly selected for vehicles, garages, workshops, boats, utility areas and other applications involving fuels, oils, solvents or electrical equipment.

Kidde offers compact BC extinguishers in different capacities, fire ratings and mounting configurations. This allows buyers to select a model according to the specific environment, available mounting space and level of fire protection required.

Why Choose a Kidde BC Fire Extinguisher?

• Class B protection: Designed for fires involving flammable liquids such as gasoline, oil and certain solvents.
• Class C protection: Suitable for fires involving energized electrical equipment.
• Compact designs: Smaller cylinders are convenient for locations where mounting space is limited.
• Vehicle applications: Selected Kidde models include secure mounting hardware appropriate for cars, trucks, fleet vehicles and mobile equipment.
• Marine options: Selected Kidde BC extinguishers are suitable for marine applications when the extinguisher and mounting arrangement meet the applicable requirements.
• Multiple fire ratings: Kidde BC models include different ratings to accommodate different applications and hazard levels.

Understanding Kidde 5-B:C and 10-B:C Ratings

Kidde BC extinguishers are identified by ratings such as 5-B:C and 10-B:C. The B portion of the rating indicates the extinguisher's relative capability against Class B flammable-liquid fires. A higher B rating represents greater fire-fighting capability for that class.

The C designation indicates that the extinguishing agent is suitable for use where energized electrical equipment is involved. Class C does not receive a numerical rating.

Choosing the Right Kidde BC Fire Extinguisher

When comparing Kidde BC extinguishers, consider the fire rating, extinguisher capacity, mounting method and environment where the extinguisher will be installed.

• Kitchen and garage protection: Compact Kidde BC models can provide targeted protection where flammable liquids and electrical equipment are the primary hazards.
• Vehicle protection: Look for a model with a secure vehicle bracket when the extinguisher will be exposed to movement and vibration.
• Fleet and service vehicles: A higher-rated BC model may be appropriate when greater extinguishing capability and a more substantial mounting system are required.
• Marine applications: Verify the extinguisher's marine approval and required mounting arrangement for the particular installation.
• Facility applications: Evaluate all hazards in the area before choosing BC-only protection instead of a multi-purpose ABC extinguisher.

Kidde BC Fire Extinguishers for Vehicles & Fleets

Vehicles present a combination of hazards that can make BC fire protection particularly useful. Gasoline, diesel fuel, oils and other automotive fluids can create Class B hazards, while batteries, wiring and energized vehicle equipment can create electrical fire concerns.

For fleet and mobile installations, the mounting system is especially important. The extinguisher should remain securely retained during normal vehicle movement and vibration while remaining readily accessible during an emergency.

Common Applications for Kidde BC Extinguishers

• Cars, trucks and SUVs
• Commercial fleet vehicles
• Service and maintenance trucks
• Construction vehicles and mobile equipment
• Garages and workshops
• Utility and mechanical areas
• Boats and marine applications
• Locations where flammable liquids and energized electrical equipment are the primary hazards

Kidde BC or Kidde ABC: Which Should You Choose?

The main difference is the range of fire classes covered. Kidde BC extinguishers are intended for Class B flammable-liquid fires and Class C energized-electrical hazards. Kidde ABC extinguishers add Class A protection for ordinary combustible materials such as wood, paper and cloth.

A BC extinguisher can be a practical choice where fuel, oil or electrical equipment represents the primary hazard. Where significant Class A combustibles are also present, an appropriately rated ABC extinguisher may provide broader protection. Extinguisher selection should always reflect the actual hazards and applicable fire protection requirements.
