Hazard Warning Signs

Hazard warning signs form part of our Safety Signs collection. Each of the signs in this department consists of a yellow triangle with a black border and an instantly identifiable black pictogram, along with a text panel containing black text on a yellow background.

These safety signs aim to identify and inform of threats, dangers, and potential health risks. We sell warning signs for a wide variety of hazards - simply select the relevant category from the list below. Alternatively, feel free to contact Label Source for further assistance.

Legally, hazard warning signs must comply with both the Health and Safety at Work Act 1974 and the Health and Safety Regulations 1996. The Health and Safety at Work Act 1974 places responsibility on the employer to keep employees safe.

The Health and Safety Regulations 1996 outline workplace regulations around hazard warning sign usage. To maximise safety, hazard warning signs must be:

  • Clear and legible
  • Related to an in-work safety policy and risk assessment
  • For a specific hazard

Under the 1996 Regulations, employers must supply hazard warning signs if needed. Without them, a risk assessment isn’t considered complete, which leaves employers liable.

Hazard warning signs have been proven to reduce workplace accidents, quell employee fears and make working safer.

The Regulations also ensured signs and labels were harmonised between the UK and the EU under the GHS system. This is still in place after Brexit, and you can find out more here:GHS: The History of the Globally Harmonized System
