What precautions must be taken for indoor electrical installations accessible to unqualified persons?

Marking electrical installations with caution signs is essential for enhancing safety, especially in areas that may be accessible to unqualified individuals. This practice serves as a visual warning, alerting people to the potential dangers associated with electrical systems. Caution signs help to prevent accidental contact with live wires or equipment, informing individuals that they should exercise care and avoid tampering or engaging with the electrical systems unless they are qualified to do so.

In environments where unqualified individuals may gain access to electrical installations, these markings are crucial in promoting awareness and minimizing the risk of electrical hazards. Proper labeling aids in accident prevention and ensures that people recognize areas that require caution, thereby reducing the likelihood of electrical accidents or injuries.
