Where guarding is part of the design, you must ensure it prevents:
- access to dangerous parts of the plant
- broken or ejected parts injuring people.
It must be a securely mounted barrier that can resist impact and shock – and can be removed only by using tools.
If access is required to parts of the plant during operation, maintenance or cleaning, the guarding should be an interlocked physical barrier that allows access when there is no risk –and prevents access at all other times.
As a last resort – or an additional precaution – the guarding should include a presence-sensing safety system.
