Home 5-B:C Class BC 2 lb. Fire Extinguisher, KD57-5BC

Hello. This extinguisher and all of our BC rated fire extinguishers use our regular dry chemical extinguishing agent powder that is 80% to 97% sodium bicarbonate, or baking soda, with 1% to 5% of calcium carbonate which is a calcium based soda powder, 1% to 5% Mica which is a stone or dust contaminant, and 0.1% to 1% clay soil which is another contaminant. On any page of the Kidde website, go to the bottom of the page and under Support you will see Safety Data Sheets. Click on that and find the Regular Dry Chemical and click on that. That will take you to the page that describes in detail how corrosive and how safe the regular dry chemical powder we use in our B:C rated fire extinguishers. Our ABC fire extinguishers use a different powder and their safety data sheets can be found there as well. B rated fires are flammable liquid fuel fires and C rated fires are electrical fires so B:C extinguishers are only rated for putting out flammable liquids and electrical fires and not A rated trash and wood and paper fires but they don't have a powder that melts and smothers and corrodes surfaces when they get heated by fires.

Is this good for a car

Hello. No, this unit is not Coast Guard approved. You will want our Marine Grade Boat Fire Extinguisher, Internet # 330137890, Model # 21028230, Store SKU # 1011654609

Hello. No, it is not specifically DOT approved.

Hello. If you are talking about electric car and electric vehicle batteries, then no. Putting out electric vehicle battery fires are very difficult. Talk to your local fire department about how to avoid electric vehicle battery fires and what to do if they occur.

Hello. Yes. It is appropriate for cars and kitchens. It will put out B class oil and grease fires and C class electrical fires and will not fuse to hot metal. However, it is not rated for A class paper, wood, and trash fires.

I bought one today and says on fire extinguisher that it is USCG approved.

Correction to previous answer: bracket must specify USCG APPROVED. see photo of HD provided installation guid.

The white 10BC with easy mount bracket, Model#: 21029286 is the USCG approved model. It is around $25

I read in the documents that it is USCG approved if used with supplied bracket and strap.

Hello. This extinguisher is not specifically USCG approved.

12 years from manufacture date on bottom. Which is 2023

Hi Kevin. Thank you for shopping at the Home Depot. Replace your fire extinguisher if the gauge reads “EMPTY,” immediately after use or if 12 years old. 80% of residential fire extinguishers sold today are single-use extinguishers that cannot be recharged. Please let us know if we can be of further assistance. Rick_HD_OC

Hello. As long as the pin and tie remain intact and the gauge is in the green, these extinguishers are good for 12 years from the year stamped on the bottom of the extinguisher.
