Safe system of work: Stacked materials

A cordon should be set up around stacked materials if there is a risk of collapse or of materials falling. The radius of the hazard area should be big enough so that debris does not fall outside it.

Access into the cordon should be prevented altogether or limited to essential tasks only. Anyone entering the cordon should be aware of the hazards and the signs of collapse so that they can withdraw if necessary.

When establishing a safe system of work, the following information will be needed and any changes monitored:

• The size of the stack
• The materials included in the stack
• The density and stability of the stack
• The likely impact on the materials or the stability of the stack of:
• The incident
• Fire and rescue service activity
• Current and forecast weather and ground conditions

Personnel should exercise caution when working near stacked materials. Unless unavoidable, they should not walk on or across stacked materials, or work on the stack.

If fire and rescue services are made aware of the presence, size, type and locations of stacked materials, they should consider recording relevant information in Location Notices.
