General Warning Signs

General warning signs should be displayed in any area where there is a potential risk to health and safety. Common locations include workplaces, construction sites, warehouses, schools, public areas, and private properties. These signs alert employees, visitors, and the general public to hazards such as slippery surfaces, high-voltage equipment, or dangerous machinery.

Warning signs act as a visual reminder of potential dangers, prompting people to take necessary precautions. For example, a "Caution: Wet Floor" sign can prevent slips and falls, while a "Danger: High Voltage" sign ensures that workers avoid electrical hazards. By clearly identifying risks, these signs contribute to accident reduction and improved workplace safety.

General warning signs cover a wide range of hazards, including:

• Slips, trips, and falls – e.g., uneven surfaces, icy paths
• Electrical hazards – e.g., live wires, high-voltage areas
• Chemical risks – e.g., corrosive substances, toxic fumes
• Mechanical dangers – e.g., moving machinery, forklift operations
• Environmental hazards – e.g., deep water, unstable ground

Yes, under the Health and Safety (Safety Signs and Signals) Regulations 1996, employers are required to use safety signs where risks cannot be entirely avoided through other means. These regulations align with the Health and Safety at Work etc. Act 1974, which places a duty on employers to ensure a safe working environment.

In accordance with BS EN ISO 7010, general warning signs are:

• Triangular in shape
• Yellow background with a black pictogram and border

This standard ensures that warning signs are easily recognisable across different workplaces and public spaces.

What is the difference between warning, prohibition, and mandatory signs?

• Warning signs alert people to potential dangers (e.g., "Danger: Asbestos").
• Prohibition signs instruct people what not to do (e.g., "No Entry").
• Mandatory signs tell people what actions they must take (e.g., "Wear Safety Goggles").
