 The Hazards

The Casualties

Nine people have dies due to carbon monoxide poisoning in small scale stores.

Tip 1.   If your current store is not vented, work with your suppliers to see how this can be achieved.

Tip 2.   Install a carbon monoxide detector in the boiler room or store entrance

Tip 3.   Wood chip and pellet stores must be kept locked and a sign displayed “Danger confined space. Permit to work required before entry” Restrict the key to authorised persons

Tip 4.    Develop safe systems of work for maintenance, including confined space entry ( see permit ) Staff will require specialist training to undertake this task or use a specialist contractor.
