Sask. OHS Regs. aren’t much help, I’m afraid. Thus, Section 25‑3(1) requires employers to ensure that portable fire extinguishers “are selected, located, INSPECTED, maintained and tested so that the health and safety of workers at the place of employment is protected” (emphasis added) but don’t specify a frequency. I’d suggest you check what your local fire code requires for your type of establishment. Glenn Demby. OHS Insider Editor-in-Chief
