Placement and access
An extinguisher is only useful if it can be reached in seconds. Choose a spot near an exit path where the handle faces outward and nothing stored in front of it can block the grip. In a vehicle, avoid areas where the unit could strike a passenger or slide under a seat in a crash, and in a home, keep it away from heat sources.
Dry chemical units need periodic attention. Check the pressure indicator or gauge on a regular schedule, look for dents, corrosion and a loose mount, and confirm the pin and seal are intact. After any discharge, have the unit recharged or replaced before relying on it, since a partly used extinguisher may not cover the next fire.
- Keep the handle clear of stored gear
- Check the mount after rough travel
- Note the discharge date after any use
