Safety Signs Regulations 1996: HSE Safety Signs Rules

Regulatory citation: Health and Safety (Safety Signs and Signals) Regulations 1996 (SI 1996/341)

What Are the Safety Signs and Signals Regulations?

The Health and Safety (Safety Signs and Signals) Regulations 1996 require employers in Great Britain to provide safety signs where a significant risk remains after other controls. They set standard colours, shapes and pictograms so a sign means the same thing in every workplace. They also cover illuminated signs, acoustic signals, hand signals, verbal communication, pipe and container labels, and the marking of obstacles and traffic routes.

Why Safety Signs Matter

Signs warn people about hazards they may not see and tell them what to do. A consistent system helps visitors, agency workers and new starters understand a sign instantly. Signs are not a substitute for controlling the risk, but they are often the last reminder before harm.

Core Obligations

1. Provide Signs Where Risk Remains (reg 4(1)–(2))

Where the risk assessment under the Management of Health and Safety at Work Regulations 1999 shows that risks cannot be avoided or adequately reduced by collective protection or safe work organisation, the employer must use safety signs. Risks are adequately reduced only when no significant risk remains.

2. Use the Schedule 1 Formats (reg 4(4))

Employers must provide and maintain signs that meet Parts I to VII of Schedule 1, and ensure, so far as is reasonably practicable, that hand signals and verbal communication meet Parts VIII and IX. Fire safety signs required by other legislation must also meet these formats.

3. Follow the Colour and Shape Rules (Sch 1 Parts I and II)

Red means prohibition, danger alarms and fire-fighting equipment. Yellow or amber means warning. Blue means a mandatory action, such as wearing PPE. Green means emergency escape, first aid or no danger. Prohibition signs are round with a red border and diagonal bar. Warning signs are triangular, black on yellow. Mandatory signs are round, white on blue. Escape, first aid and fire-fighting signs are rectangular or square.

4. Label Containers, Pipes and Stores (Sch 1 Part III)

Containers of hazardous chemicals and visible pipes carrying them must show the relevant CLP hazard pictograms. Pipe labels go near dangerous points, such as valves and joints, and at sensible intervals. Areas storing significant quantities of hazardous substances must have a warning sign. Containers used briefly or with frequently changing contents may be exempt if equivalent protection is ensured.

5. Mark Obstacles and Traffic Routes (Sch 1 Part V)

Obstacles and places where people may fall, collide or be struck by falling objects must be marked with alternating yellow and black or red and white stripes at about 45 degrees. Where needed, vehicle traffic routes must be marked with continuous stripes in a clearly visible colour, preferably white or yellow.

6. Make Alarms and Signals Clear (Sch 1 Parts VI, VII, VIII and IX)

Flashing signs indicate greater danger than continuous ones. Acoustic signals must be clearly audible above background noise, and the evacuation signal must be continuous. Verbal messages must be short and clear, and hand signals must be precise and distinct, with the signaller able to see the whole operation.

7. Use Road Traffic Signs for Vehicle Risks (reg 4(6))

Where there is a traffic risk at a workplace and a suitable road traffic sign is prescribed under the Road Traffic Regulation Act 1984, that sign must be used, even on private premises.

8. Train Employees (reg 5)

Employers must give employees comprehensible information on the measures linked to signs, and suitable instruction and training on what signs mean and what to do.

Common Compliance Approaches

Link Signs to the Risk Assessment

Record which residual risks need a sign, and remove signs once a hazard has gone. Too many signs cause confusion.

Use Standard Pictograms

HSE guidance L64 includes details of BS EN ISO 7010 safety sign designs.

Example: Safety Signs in Practice

A food manufacturer reviews signage after adding a new chemical cleaning area. It fits CLP labels to the chemical containers and pipework near valves, posts a warning sign on the store door and adds blue eye protection signs at the dosing point. Forklift routes are marked with yellow floor lines, and a low beam is striped yellow and black. Supervisors brief all shifts on the new signs during toolbox talks.

Note: The regulations do not cover labelling for the supply of substances, the transport of dangerous goods, or signs regulating road, rail, waterway, sea or air traffic. They apply in Great Britain, and Northern Ireland has equivalent but separate legislation. Always check the current legislation and HSE guidance.

Frequently Asked Questions

When are safety signs legally required?

When the risk assessment shows a significant risk remains after other control measures, such as engineering controls and safe systems of work, have been used.

What do the safety sign colours mean?

Red is for prohibition, danger alarms and fire-fighting equipment. Yellow or amber is for warnings. Blue is for mandatory actions. Green is for emergency escape, first aid and no danger.

Do fire exit signs fall under these regulations?

Yes. Where fire safety legislation requires a sign, it must follow the formats in Schedule 1 of these regulations.
