What must be posted at all major electrical installations for safety purposes?

At all major electrical installations, it is essential to post suitable danger signs to ensure safety. These signs serve to inform personnel and visitors about potential hazards in the vicinity, such as high voltage areas or the presence of electrical equipment. The primary goal of these signs is to effectively communicate risks and promote safe practices around electrical installations.

Suitable danger signs often include clear wording or symbols indicating the nature of the threat, such as "Danger - High Voltage" or "Electrical Hazard." This visibility helps in preventing accidents by making everyone aware of the hazards, thereby encouraging adherence to safety protocols.

While warning symbols could be considered part of this communication strategy, they are generally encompassed within the broader category of danger signs. Emergency contact numbers, while important for safety management, do not specifically address the immediate hazards present at electrical installations. Maintenance schedules, on the other hand, relate to the upkeep of the installation and do not serve the purpose of alerting individuals to potential safety risks.
