Flammable Signs

In workplaces where flammable materials are present, Flammable signs are a vital component of workplace safety policy. They play a crucial role in warning staff and visitors to the presence of flammable substances and materials that could catalyse a fire or explosion. 

Whether you’re managing a warehouse, factory or laboratory, these signs provide an impactful alert that reminds people to avoid naked flames, sparks, or careless handling that could cause a potentially life-threatening fire or explosion.

We manufacture our signs in a range of different sizes, signage materials and finishing options, ensuring you can customise your sign to align precisely with your bespoke application requirements. 

Why Flammable Warning Signs Are Necessary

Flammable warning signs play a vital role in preventing fires, explosions, and serious workplace injuries. They provide a strong visual cue that something in the area can ignite easily, whether that’s fuel, chemicals, gases, solvents, or combustible liquids. 

Not only are these danger highly flammable signs advised, but they are also mandatory under UK Law. From a legal perspective, UK employers have a duty to protect employees and visitors under the Health and Safety (Safety Signs and Signals) Regulations 1996 and The Dangerous Substances and Explosive Atmospheres Regulations 2002 (DSEAR). These regulations place a responsibility on employers to display safety signs where foreseeable risks cannot be controlled or mitigated by any other means. 

HSE guidance also states that hazards involving fire or explosion must be clearly marked. This is particularly relevant for: 

Fuel storage rooms

Chemical stores

Spray booths

Workshops using solvents

Gas cylinder areas

Laboratories

Failure to comply with these regulations and guidelines exposes your business to serious legal risks, including fines, enforcement actions, and even prosecution in some cases. 

Material Options & Best Use Cases

With a variety of signage materials available, choosing the right material for your bespoke application requirements can feel daunting. However, it’s actually quite simple to choose.
