HSE Awareness Alert HSE Awareness Alert 2007/04/01 Electric Overhead Lines can kill April 2007 Two fatalities and one LTI due to cranes getting close to electric overhead lines: You need to be aware of the dangers of working in close proximity of electric overhead lines. For example: o On 6 November 2006 a crane operator was electrocuted when the crane boom came too close to an adjacent 11.000 Volt Overhead Line. The operator was unconscious and was rushed to a nearby clinic where he died shortly afterwards. o On 17 September 2006 a MET Tower Technician was fatally injured from electrocution. While raising the MET Tower, it came into contact with a high voltage overhead power line. o On 26 July 2006 a crane operator was electrocuted when moving a welding machine. The crane arm got close to the overhead line affecting the operator who was standing next to the crane controls operating them.

Electrocution may lead to severe burns or to death as a consequence of heart standstill. What to do? Work planner and permit issuer: 1. Work on energized equipment/lines within the minimum safe approach distance is never allowed. 2. If work outside the minimum safe approach distance is planned, then the following is required: o Formal work pack with method statement; o Lift Plan prepared and reviewed by a qualified engineer; o Risk assessment; o Job Safety Analysis; o Work Permit; o Safety checklist; o Toolbox Talk; o 10 questions for a safe lift 3. If possible set limits to the crane reach in horizontal and vertical direction 4. Make sure you and your contractors involve the electrical department and have the right competent people (crane operator, flag man, slinger/rigger etc). In case of crossing underneath an electrical overhead line make sure it is done at the dedicated road crossing points and you keep adequate clearance.

Two fatalities and one LTI due to cranes getting close to electric overhead lines: You need to be aware of the dangers of working in close proximity of electric overhead lines. For example:o On 6 November 2006 a crane operator was electrocuted when the
crane boom came too close to an adjacent 11.000 Volt Overhead Line. The operator was unconscious and was rushed to a nearby clinic where he died shortly afterwards.
o On 17 September 2006 a MET Tower Technician was fatally injured from electrocution. While raising the MET Tower, it came into contact with a high voltage overhead power line.
o On 26 July 2006 a crane operator was electrocuted when moving a welding machine. The crane arm got close to the overhead line affecting the operator who was standing next to the crane controls operating them. The operator ended with severe burns on his forearm and feet, which required specialized medical treatment.
