Control of Hazardous Energies Standard / V5 10032026
5) Where the possibility of stored electrical energy exists, this must be isolated or insulated. Where this is not possible the energy must be dissipated by using an approved tool rated and designed for the purpose
6) Verify absence of voltage to verify that the circuit parts are de-energised
7) For low voltage circuits with the possibility of induced voltage, apply short- circuiting earth connections rated for the fault current 8) Apply lockout/tagout devices in accordance with the local legislation and specific company procedure and rules. Depending on the configuration of the circuit it may be necessary to perform this step prior to steps five – seven
Minimum arc flash PPE
Minimum arc flash PPE includes:
eye protection / safety glasses and hard hat
•
• non-melting clothing including underwear, with long sleeves and long trousers. small parts of melting materials are acceptable, e.g. elasticated waistbands, but should be reduced to the minimum possible, ideally eliminated • safety footwear with non-melting materials, acceptable exceptions are the sole and shoelaces • any tasks-specific PPE such as gloves, visors, etc. Note For further detailed guidance refer to the GWO High Voltage Standard
Pre-task briefing
Before starting each job, the person in charge of the job must conduct a briefing with the employees involved. The briefing must cover such subjects as:
hazards related to the job tasks
•
work procedures involved
•
special precautions
•
energy source controls
•
• personal protective equipment requirements
Safe handling of batteries and capacitors
How?
a) always visually inspect the batteries and capacitors before starting work; look for signs of distress and leakage b) take precautions to guard battery terminals against short circuiting by covering the terminals with insulating tape or insulating mats
c) ensure all batteries and capacitors are correctly and securely mounted
