Workplace Safety Signs: What Employers Need to Know
Updated ·4 min read
The Health and Safety (Safety Signs and Signals) Regulations 1996 ask employers to provide safety signs where a significant risk to health and safety remains after other measures are in place. Guidance from the Health and Safety Executive (HSE) also warns against using too many signs.
We print signs on aluminium composite and Foamex that you can buy online, and we make bespoke safety signs to order through our safety signs category. This guide is general information, so check the wording of your own signs against HSE guidance.

What the Regulations Require
HSE guidance L64 explains how to comply with the Regulations. It says signs and signals are needed when, after all other relevant measures are in place, a significant risk to health and safety remains. Signs are the last step, not the first.
Under regulation 4 of the Regulations, the employer must provide and maintain the appropriate safety signs where a risk assessment shows that a risk cannot be avoided or adequately reduced by other means. The guidance is for employers and others who control workplaces.
HSE also says to avoid too many signs, because they can cause confusion.
The Four Sign Types
HSE says signs should be used for prohibited actions, safeguards that must be followed, hazard warnings, and directing people to fire exits, fire equipment or first aid. The Regulations set colours and shapes for each:
- Prohibition: round, with a black pictogram on white, red edging and a red diagonal bar. Example from HSE: no access.
- Warning: triangular, with a black pictogram on yellow and black edging. Example: corrosive material.
- Mandatory: round, with a white pictogram on blue. Example: ear protection.
- Safe condition (emergency escape and first aid): rectangular or square, with a white pictogram on green.
Fire-fighting equipment signs are rectangular or square, with a white pictogram on red.
Fire Safety Signs
HSE refers to fire exit and fire equipment signage, and lists the Regulatory Reform (Fire Safety) Order 2005 as related fire legislation. The Order applies in England and Wales, and HSE lists the Fire (Scotland) Act 2005 for Scotland.
Under the Order, emergency routes and exits must be indicated by signs. The Order also covers fire risk assessment, which is a separate duty from providing signs.
Keep Signs Maintained and Explained
The Regulations ask for more than putting a sign up.
- Maintain them: signs must be cleaned, checked, repaired and replaced when necessary, so they stay clear. Poor condition reduces how well a sign works.
- Use suitable materials: signboards must be made of shock- and weather-resistant material suitable for their surroundings.
- Remove old ones: a sign must come down once the situation it refers to no longer exists.
- Explain them: employees must be given comprehensible and relevant information on the measures connected with safety signs, and suitable and sufficient instruction and training in what the signs mean.
Materials That Suit Workplace Signs
- Outdoors: flat aluminium composite signboards are 3mm printed aluminium composite for outdoor use, from £16.00 including VAT.
- Indoors: flat Foamex signboards suit indoor use, from £10.50 including VAT.
- Site entrances and car parks: a post and panel sign stands on its own, which suits entrances and car parks.
- Car park bollards: bollard covers are printed Correx sleeves that carry safety messaging.

Common Questions
Do I have to put up safety signs?
Under the Regulations, signs are needed when a significant risk remains after other measures are in place. Your risk assessment shows whether that applies. HSE also warns against too many signs.
What colour is a warning sign?
Warning signs are triangular, with a black pictogram on yellow and black edging.
What colour are fire exit and first aid signs?
Emergency escape and first aid signs are rectangular or square, with a white pictogram on green. Fire-fighting equipment signs use a white pictogram on red.
Do employees need to be told what the signs mean?
Yes. The Regulations require employers to give employees relevant information on the measures connected with safety signs, and training in what the signs mean.
Can you make a safety sign to my own design?
Yes. Ask for a quote on our quote page for made-to-order signs, or print your own artwork on a Foamex or aluminium composite board.
