What is required when signs and barricades do not sufficiently warn employees of electrical hazards?

When signs and barricades are not adequate in warning employees of electrical hazards, stationing an attendant to warn employees is essential. This approach ensures that there is a knowledgeable individual on site who can communicate potential risks directly and provide real-time warnings to anyone approaching the hazardous area.

The presence of an attendant serves several purposes: it allows for immediate intervention if someone is about to enter a dangerous zone, fosters awareness of the ongoing risks, and reinforces the importance of safety protocols among all team members. This proactive measure can significantly reduce the likelihood of accidents related to electrical hazards, as the attendant can actively monitor the area and ensure that safety practices are upheld.

Other options may rely on static measures or evacuation without addressing the immediate human element of safety communication and monitoring. Therefore, having an attendant on site is a practical and effective response to the inadequacy of signs and barricades.
