Safety Signs That Make Hazards Obvious — Before Incidents Happen

Safety signs are essential wherever a risk remains after other controls. They communicate hazards, required actions, emergency routes and prohibited behaviour instantly — using recognised colours and symbols so the message lands in seconds.

That speed matters. The right safety sign can stop a fall, prevent a burn, avoid a collision, or keep someone away from live electrics. In busy environments like construction sites, factories, warehouses, schools and public areas, signage isn’t a nice-to-have — it’s a frontline safety control.

At HFE Signs, our safety signs are designed to be:

• Highly visible from the right distance

• Easy to understand at a glance

• Durable indoors or outdoors

• Compliant with UK/ISO standards

Warning Signs: The Most Important Safety Signs on Any Site

Warning signs are a specific category of safety signs used to alert people to a hazard ahead. They’re the yellow triangle signs you see on sites because they do one job brilliantly: make danger unmistakable.

A well-placed warning sign:

• reduces near-misses and injuries

• protects staff, visitors and contractors

• supports HSE expectations and risk assessments

• helps you demonstrate compliance if inspected

Common warning signs include:

• Warning: High Voltage

• Warning: Forklift Trucks Operating

• Caution: Slippery Surface

• Warning: Hot Surface

• Danger: Fragile Roof

• Warning: Hazardous Chemicals

If there’s a hazard that can’t be fully removed — warning signs are the clearest, quickest way to control it.
