OSHA Regulations on Crane to Prevent Crane Boom Electrical Power Line Contact and Crane Electrocution Accidents
OSHA Crane Rules & Guidelines to Prevent Crane Boom Electrical Contact and Electrocutions
Current OSHA regulations require employers to take precautions when cranes and boomed vehicles are operated near overhead power lines. Any overhead power line shall be considered energized unless the owner of the line or the electric utility company indicates that it has been de-energized and it is visibly grounded [29 CFR 1926.550 (a)(15)(vi)]. The OSHA regulations are summarized as follows:
Employers shall ensure that overhead power lines are de-energized or separated from the crane and its load by implementing one or more of the following procedures:
â€”De-energize and visibly ground electrical distribution and
transmission lines [29 CFR 1910.333(c)(3); 29 CFR 1926.550(a)(15)]
â€”Use independent insulated barriers to prevent physical contact with
the power lines [29 CFR 1910.333(c)(3); 29 CFR 1926. 550(a)(15)]
â€”Maintain minimum clearance between energized power lines and the
crane and its load [29 CFR 1910.333(c)(3)(iii); 29 CFR
1926.550(a)(15)(i), (ii), (iii)].
Where it is difficult for the crane operator to maintain clearance by visual means, a person shall be designated to observe the clearance between the energized power lines and the crane and its load [29 CFR 1926.550(a)(15)(iv)].
The use of cage-type boom guards, insulating links, or proximity warning devices shall not alter the need to follow required precautions [29 CFR 1926.550 (a)(15)(v)]. These devices are not a substitute for de-energizing and grounding lines or maintaining safe line clearances.
