- Open electrical panels present exposure hazards. Close whenever possible.
- Do report broken or damaged panel doors.
- Do exercise caution closing a door. If you think closing an Electrical Panel Door poses an electrical hazard, contact the appropriate personnel to close it.
- If a person becomes energized, that person must be safely separated from the electrical power, or the electrical power shut off or removed.
- Remove the current source by operating the disconnect. Time is short, prolonged exposure to electrical shock causes increased personal damage.
- Do not touch the person who is in contact with electricity.
- Do not reach blindly into areas that might contain live energized equipment.
- Do not distract or put yourself in a position that might distract another person working on energized equipment. Looking over an Electrician's shoulder while he/she is working in an Electrical Panel is a dangerous practice that could put you and the Electrician's life in danger.
- Do illuminate areas to help provide a safe work environment.
- Do keep the areas in front of electrical equipment clear.
- Do remove conductive articles of clothing or jewelry such as watches, bracelets rings necklaces before starting work.
- Do use only properly insulated tools rated for the Approach Boundary area where work is to be performed.
- Do avoid touching or leaning on equipment that could potentially be energized or come in contact with energized equipment (metallic surfaces).
- When operating switchgear (energizing or de-energizing): switch remotely if possible, stand aside as much as possible if manually switching, using proper PPE.
- Never assume that you know how a circuit is wired. Ask for help and/or consult a wiring diagram/schematic if you are unsure.
- Apply lockout / tagout devices in accordance with established policy, your lock is your PERSONAL key to staying ALIVE! Always use your own lock. Never have someone else do it for you.
- Always TEST to ensure there is no voltage inside an electrical enclosure prior to working on it. Use adequately rated equipment to test each phase conductor phase-to-phase and phase-to-ground. Before and after each test, determine that the voltage detector is operating satisfactorily.
- Do not bypass or defeat electrical safety devices or circuitry.
