A fire is bad enough. It's even worse when you use a dry chemical fire extinguisher on an engine, electrical or computer fire. You'll find the powder makes a mess and does enormous damage to delicate engine, electrical and some metal parts. If you're smart enough to keep fire extinguishers around your garage, home and in your vehicles I applaud you. Now, you can keep the right kind for the proper use. Halotron 1 is EPA approved. It's much more environmentally safe than Halon 1211. It has a low global warming potential and low ozone depletion potential due to its short atmospheric life. It's a clear liquid, stored under pressure, that vaporizes upon release. It doesn't degrade like powders do so its shelf life is up to 11 years. The vapor won't obscure your vision while fighting the fire and its non-conductive properties provide fast, clean fire control. Keep one in your garage, home, office and each vehicle. The trigger and nozzle are high quality, and the built-in gauge lets you know when it's time to refill. 1.4 lb. bottle diameter is 2 5/8" and 9 3/4" tall. 2.5 lb. bottle diameter is 3" and 14 1/4" tall. These bottles are masterfully crafted, have rubber seals and feature a simple mounting bracket with quick-release latches for fast access. Made in the U.S.A.
