Fire safety signs are used to provide health and safety information, either to warn you of a hazard, to provide an instruction or to give you safety information. Safety signs can be a variety of colours – usually red, green, yellow or blue – and may contain images, words or a mixture of the two. It’s essential that you adhere to the fire safety signs in your workplace and any other public space: they are there for your safety and ignoring them could have serious consequences.
