SafetyCâu 524 / 700
An overhead power line runs near a site where a crane and a dump truck will operate. What is the BEST way to prevent electrocution from contact with the line?
a.Assume the line is insulated and work directly beneath it
b.Have a worker hold the line away with a wood pole
c.Maintain the required minimum clearance distance from the line, or have the utility de-energize or cover it, and use a spotter
d.Work faster to spend less time near the line
Giải thích
Cal/OSHA requires equipment to maintain a minimum safe clearance from energized overhead lines; where that clearance cannot be assured, the line should be de-energized, relocated, or insulated by the utility, and a dedicated spotter used. Option c reflects this. Overhead lines are usually bare, not insulated (a), a wood pole is not a safe barrier (b), and rushing (d) increases the chance of fatal contact.
