Electrocutions – no second chances

Common underlying factors in electrocutions which lead to serious injury and death include; the MEWP operator working away from a controlled site; not expecting to encounter or be close to overhead lines; lone working; working unsupervised, with no-one to spot dangers or raise the alarm from the ground.

Anyone planning work using MEWPs where there is a potential electrocution hazard should:

• Observe minimum safe distances from power sources/overhead power lines.
• Where this is not possible, ensure overhead power lines are isolated and grounded to prevent static build-up.
• If use of an Insulated Aerial Device (IAD) is recommended; operators must be trained and familiarised accordingly.
• A safe work plan should identify power sources and a site assessment for MEWP selection must include a walk-through with a “look out, look up” procedure to identify overhead power lines.
• Beware, leaning out of the platform, moving conductive materials, pointing or gesturing with an outstretched arm as this could breach safe distances and cause electricity to arc.
• Weather conditions, especially moisture content of the air, should be considered during the risk assessment.
