Generally, it is recommended that businesses have one extinguisher for every 3,000 square feet of space, with additional units placed in high-risk areas like kitchens or workshops. Ultimately, a thorough risk assessment should be conducted to determine the precise number required to ensure adequate safety and compliance with local regulations in Cheshire.
