There are some confined spaces that you shouldn’t enter. It is a requirement that notices at confined space entrances are displayed to reduce the risk of injuries or fatalities in restricted areas. Only authorised and trained personnel should attempt access to confined or restricted spaces and must obtain a permit to work before commencing.

The Health & Safety (Safety Signs and Signals) Regulations 1996 state that hazard signs must be displayed to warn people to be careful or to take precautions where hazards exist.
