Safe
isolation means safe
maintenance
When it comes to working on electrical installations, be it maintenance of equipment, installing new build or adding new circuits, implementing safe isolation procedures is essential to achieve compliance with the Electricity at Work Regulations and stay safe. Steve Dunning of Martindale explains what’s needed to keep your team safe and achieve compliance.
T
here are around 1,000 serious accidents per year at work due to contact with electricity and 10 times as many involving electricity, many of which could be avoided by following simple procedures and using the right equipment to the latest standards. In addition, average fi nes for non-compliance have tripled over the last year.
Guidance requires operators to work dead whenever possible and achieve this by following a clearly defi ned procedure which involves isolating the source of supply, locking off the supply and

proving dead before any maintenance work is carried out. ■ Employers cannot and should not assume that employees have the right equipment
■ Regular inspections of equipment should be carried out
■ It’s the responsibility of management to ensure correct supervision and procedures are in place.
Ensuring the right tools are available for the job might seem like common sense, but it’s still an issue among some maintenance teams, who may
be potentially putting their lives and those of their colleagues at risk.
For example, using a multimeter to prove a circuit is dead is not permissible as it could easily give a misleading reading if set to the wrong range or if the batteries need replacing. A dedicated voltage indicator which has no ranges, switches or batteries is by far the most reliable method for proving dead. In addition, having the right locking off device to hand for all types of common circuit breakers or fuse holders is a must.
