• Ensure only HV-authorised persons work on or near high voltage cables and terminations.
• Use cranes and drum trailers for handling heavy HV cable drums — never roll them manually.
• Establish exclusion zones along the pulling route during cable installation operations.
• Maintain clean, controlled conditions during HV cable jointing operations.
• Enforce strict exclusion zones during hipot testing — the test voltage is instantly lethal.
• Confirm the position of existing live HV cables before working in the same trench.
• Store cable drums on firm, level ground, chocked securely against rolling.
• Backfill with specified cable surround material and install warning tape at the correct depth.
• Brief all workers on HV cable locations and the exclusion zones in force.
• Follow the electrical safety rules and permit procedures for all HV cable work.

• DON'T work on HV cables without valid HV authorisation and the required competency.
• DON'T manually handle HV cable drums — they weigh tonnes and cause crush injuries.
• DON'T stand in the cable pulling path — failed connections cause violent cable whip.
• DON'T carry out HV jointing in dirty, wet, or uncontrolled conditions.
• DON'T approach cables under hipot test — the voltage is far above operating level and lethal.
• DON'T dig near existing HV cables without confirming their exact position first.
• DON'T leave cable drums unsecured — they can roll and crush workers or damage property.
• DON'T use incorrect backfill material or omit the warning tape above the cable.
• DON'T ignore HV cable exclusion zones — they exist because the cables can kill.
• DON'T bypass the electrical permit and safety rule procedures for HV cable work.
