Douse fires without harming sensitive electronics. These extinguishers have a nonconductive spray that won’t leave powder or residue behind. All are rated to UL Class B and C standards for fire protection. Class A and B ratings also include a number; the higher the number, the greater the firefighting power.

Carbon dioxide extinguishers displace oxygen to suppress a flame, so they're less effective than Halotron extinguishers in windy environments.

Halotron extinguishers can propel their agent three times farther than carbon dioxide extinguishers, so you can stay at a safe distance from flames. Often used in data centers and server rooms, they can reach fires behind equipment and other obstacles.

Halotron BrX extinguishers have a more concentrated agent than standard Halotron extinguishers, so you can put out fires with a smaller amount. They’re often used in confined spaces and areas where weight matters, such as airplanes.

Most extinguishers come with a bracket for mounting. Surface brackets hold an extinguisher upright on a wall or other flat surface. Vehicle brackets are more secure than surface brackets—they keep extinguishers from shifting while you’re in motion. Aircraft brackets are D.O.T. or FAA approved to secure extinguishers on commercial airplanes.

Extinguishers that cannot be sold to Canada are restricted due to import regulations.
