Health & Safety (Safety Signs and Signals) Regulations 1996 make it clear hazard signs must be clearly displayed to warn people of dangers from hazardous working environments or substances, or to take appropriate cautions in the face of these risks. These signs exist for the benefit of staff working in hazardous environments, as well as general members of the public, who may be exposed to any risks these workplaces pose.

These yellow signs with bold black text warning of the dangers of an explosive environment comply with this legislation and are vital for use in environments where there is any danger of explosion. Also known as the Ex Symbol sign, these are available in Polypropylene rigid plastic with a satin finish, and can be drilled to the walls for both indoor and outdoor use.

Alternatively, self-adhesive signs in both rigid plastic and vinyl are available and these are durable enough to be used both indoors and outdoors too. The vinyl signs have a high gloss finish, for durability and easy cleaning, while the satin finishes of the plastic signs are also clear and easy to both read and clean.

The signs can be positioned anywhere they are needed and are available in a range of sizes for all the needs of industry. Both landscape and portrait options are available, in sizes which range from 100 x 250mm to 841 x 594mm or A1 sized. However, the A1 size is only available in the Polypropylene rigid plastic option.

Sign screw fixings and button screw sign fixings are also available.
