What must be posted at all major electrical installations?

• A. Danger signs
• B. Warning labels
• C. Caution markers
• D. Electrical notes

Answer: (A)

Posting danger signs on major electrical installations communicates an immediate, life-threatening hazard from electrical equipment, such as the risk of electric shock or arc flash. The word “danger” signals that a serious injury could occur if proper precautions aren’t followed, so these signs must be clearly visible at access points and around the equipment to keep workers out of harm’s way or to instruct them on safe procedures. This is the level of warning appropriate for high-energy electrical sites in mining, aligning with safety standards that prioritize clear, unmistakable notice at the source of the hazard. Warning labels are more about describing specific hazards on individual components, which is not the same as the broad, prominent notice required for entire installations. Caution markers indicate a lower level of hazard and are not typically used for the serious risks posed by major electrical equipment. Electrical notes are just documentation and do not substitute for visible warnings at the installation.
