Extinguishers must be fully inspected once a year according to the Canadian OH&S Law and Regulation and should be manually inspected once a month. The monthly inspection includes:
- Checking the condition of the extinguisher parts
- Shake the extinguiser
- Verify the pressure gage arrow
Any used extinguisers must be removed from the workplace and replaced as soon as possible. Maintaining an Excel spreadsheet up to date will help the OH&S councellor about when to inspect the extinguishers.
