One of the biggest tasks faced in ensuring good health and safety practice is the communication of information. It is vital that everyone concerned understands risks and how they should be dealt with. For this reason, the proper signage in a workplace is essential, as it is one of the main points of reference and contact for staff. These signs should be found anywhere in which a potential hazard might be found, and the aim is to clearly indicate the danger so that it may be avoided. Other signs actually explain the precautions to take in order to avoid the hazard.
