What are warning signs?

Warning signs are a form of highly visible signage that requires the immediate attention of the viewer. They highlight an approaching hazard, obstacle or action that must be taken to stay safe. An example of a warning sign is a cleaning sign placed after mopping the floor: 'Caution Wet Floor' is usually coupled with an image of a figure slipping over.

Compliant warning signs typically use primary colours to ensure they're bold and highly visible. For signage that's positioned permanently, a photoluminescent design is utilised so that signage is visible in all light levels.

Why buy warning signs?

According to the Health and Safety (Safety Signs and Signals) Regulations, 1996, if there is a significant risk to employees that cannot be managed using safe systems of work, then safety signs must be placed. This responsibility includes the provision of training to make sure that all employees are familiar with the reason for the signage and what it means.

Warning sign types

Warning signage is universally recognised and easy to understand. Governed by ISO safety standards, all types of warning signs must conform with BS EN ISO 7010.

Access restriction signs   -   These signs are red and white and make the viewer aware when access to a certain area is restricted, such as a No Entry sign for example.

Construction signs   -   These signs highlight any dangers associated with construction, such as live wires or workers near the road. These signs use yellow, black, and white as their main colours.

Hazard signs   -   These are designed to make the viewer aware that they're approaching a hazard, and include moving vehicles, gas and explosions and electric shock risks.


Multi-message signs   -   These signs are utilised when there are multiple risks ahead and action must be taken, for example, 'Danger Moving Vehicles, Keep to the Right'.

Prohibition signs   -   These are essentially 'Do Not' signs, like 'Do Not Use Mobile Phones' situated on a petrol station forecourt.

Tactile & braille signs   -   To ensure inclusivity in the workplace and that all staff and visitors remain safe, all warning signs are available with tactile and braille options to keep visually impaired staff safe.

Auditory warnings   -   These can be verbal or non-verbal and are also designed for visually impaired staff.

Considerations when choosing warning signs

Human behaviour - employers should take into consideration the nature of human behaviour when choosing the types of warning signs to use. Behaviours such as willful ignorance and misinterpretation should be thought through and incorporated into staff training.

Risk Assessments - as part of safe systems of work, a risk assessment will help to identify hazards and the signage type required.

Positioning - for sign placement, see www.hse.gov.uk where there is a comprehensive guide to viewing distance and the corresponding height of signage.

Inclusivity - it's important to make provisions for staff and visitors who have visual impairments to protect everyone on site.

Maintenance - to ensure signage remains in good condition, and any auditory signs are maintained a maintenance schedule should be drawn up and assigned with broken or damaged signage replaced as soon as possible.
