Construction Site Safety Signs


Reading time: 3 minutes

What are the different types of safety signs and what do they mean?

Employers, site managers and forepersons hold a duty of care to their employees and public visiting a building site, and are responsible for the compliance of health and safety. These signs are also a legal requirement, as outlined in the Health and Safety (Safety signs and signals) Regulations 1996. Safety signage is essential to clearly indicate potential hazards and avoid danger - reducing the risk of an accident. So, here we explain the four different types of safety signs that you could come across whilst on site, and show you some examples of what they look like and what they mean.

  • Mandatory signs
  • Safety signs
  • Prohibiting signs
  • Hazard signs

Do safety signs need to be a certain size?

In short, the answer is no - there are no rules which formally dictate the sizing of warning signs. The only requirement stated in the Guidance of Regulations is “Where signboards are used in a workplace, ensure that they are sufficiently large and clear to be easily seen and understood.”, and “...size should be appropriate for intended viewing distance…”. Although this advice is quite vague, the size needed should become more apparent with a construction site risk assessment.
