Mandatory signs are safety signs that make basic health and safety information clear.

They highlight information that should be followed by both personnel and non-personnel alike.

This includes information like safe walking routes and whether PPE is required in the area.
A wide range of mandatory signs are available to buy on the SMI store!

You can also explore our signs and labels category, where you’ll find every type of safety sign you need.
Mandatory signs make it easy to follow basic health and safety rules.

Mandatory signs often highlight the following safety requirements:
- Where to throw away rubbish
- Restricted areas and who can access them
- If a certain area or doorway needs to be kept clear
- To indicate if a door is a fire door and needs to be kept shut
- If PPE should be worn, such as head protection or hi-vis vests
Mandatory safety signs are easy to recognise by their blue background with white text and icons.

This consistent colour scheme helps workers quickly identify instructions and requirements in any workplace environment.
Mandatory signs should be placed in clear, easy-to-see locations near hazard areas.

Always mount them at eye level and ensure they are never blocked or obscured by equipment, furniture, or other signage.
