Gas and Explosive Safety Signs

Across UK industries, Gas and Explosive safety signs play an absolutely vital role in minimising the risks associated with flammable gases, vapours, or explosive materials present on site. 

Whether you’re looking to tighten Health and Safety measures at a factory, industrial facility, construction site or in everyday work offices, our explosive safety signs provide an effective warning to staff, visitors and contractors to take specific precautions while operating on your premises. 

With a variety of designs, sizes, signage materials and finishing options to choose from, we ensure we can cater towards all workplace Health and Safety sign requirements. 

Why Explosive Safety Signs Are Necessary?

In areas where gas leaks, explosive atmospheres, or ignition risks exist, our exposlive risk signs play a vital role in mitigating these risks. Given that many explosive materials are completely invisible to the naked eye, our signs are an essential mitigation strategy to prevent explosions. 

Under UK Health and Safety Regulations (Health and Safety (Safety Signs and Signals) Regulations 1996), UK employers have a legal responsibility to communicate the risks of hazards clearly across their site. 

Additional pieces of legislation that relate to the use of safety signs to manage explosive risks include the Control of Substances Hazardous to Health (COSHH) Regulations 2002, CLP Regulation (Classification, Labelling and Packaging) 2009 and the Dangerous Substances and Explosive Atmospheres Regulations (DSEAR) 2002.

Our range of explosive signage helps businesses demonstrate compliance with these regulations and protect themselves from costly legal challenges, fines and enforcement action. 

A well-positioned explosive hazard sign often acts as a final safety layer. Even when systems, training, and procedures are not adhered to, a clear warning sign can be enough to stop overisghts from becoming a serious incident.

Material Options and Best Use Cases

With a variety of signage materials available within their range, finding the right one for your specific needs and application requirements can often feel daunting. 

However, it’s actually a lot simpler than you think. Provided below is a quick breakdown of each one of our signage options and their best intended use cases:

Self-Adhesive Vinyl

Primed for short to medium-term indoor use cases. These stickers are exceptionally cheap and feature a high-tack adhesive backing for a tight bond to smooth indoor surfaces. 

Rigid Plastic

Intended for long-term indoor use, our Rigid Plastic boards offer greater durability and longevity than self-adhesive vinyl. Highly lightweight, they are super easy to install and will last between 3-5 years indoors. 

PVC Foamex

Suitable for indoor or outdoor use cases, Foamex is an exceptionally versatile signage material. Highly resistant to whatever the weather throws its way, it’ll last between 3-5 years outdoors and between 5-7 years indoors. 

Aluminium Dibond

Designed for outdoor use or demanding indoor industrial environments, Dibond offers unrivalled durability and longevity. Will last up to a decade indoors or outdoors. 

How to Position Explosion Risk Signs for Maximum Effect

The placement of your explosive signs is just as important as the signage material you choose. For maximum impact, Gas and explosive safety signs should be installed at site entrances, entrances to hazardous working zones, near gas lines and valves, and close to control panels. 

Always try to display the signs as close to eye level as possible to ensure they cannot be overlooked. Around 1.6 metres from floor level tends to provide the best visibility. 

Additionally, ensure the signs aren’t put in cluttered areas such as notice boards, as this hinders their visibility. You should also ensure that sightlines are completely unobstructed at all times.
