Our Electrical Safety Training is designed to ensure that both employers and employees understand the main risks and the necessary controls for the safe use of electricity at work.

A large part of being safe around electricity is understanding common electrical safety symbols. Take a look at our useful guide to find out more:

PAT Labels

The following labels can be found on appliances that have undergone  Portable Appliance Testing (PAT). They advise whether an appliance is safe or unsafe to use, and may be circular or rectangular. The green ‘passed’ PAT label features the test date and sometimes the name of the person who carried out the test, as well as the date of the next test. Any equipment with a red ‘failed’ PAT label should be removed from use immediately.


You may also see other labels, similar to the red and green PAT labels, which identify whether equipment, appliances and instruments have been checked and are safe to use:

The text and colour of the signs may vary, but the pictograms are universal. They are used to warn you of the potential electrical hazards in the area and must not be ignored. Examples include:
