HAZARD MITIGATORS - ELECTROCUTION <br /> Applies to Task: M O 10 ❑ OO ❑ ® ❑ OO ❑ © ❑ OO ❑ <br /> • Install adequate; warning signs and barriers (in plain sight) in all areas where hazardous <br /> electrical facilities exist. <br /> • Use only heavy duty electrical cords that are not subjected to excessive bending, <br /> stretching, or kicking. All cords and wires shall be frequently inspected for signs of <br /> defects. Damaged or frayed electrical wires, cords, and plugs shall be immediately <br /> replaced by a qualified electrician or other properly trained personnel. <br /> • Equip all portable extension cords with a non-conducting plug and/or another socket shell. <br /> All electrical cords shall be equipped with three-blade grounding type plugs. <br /> • Do not permit overloading of electrical circuits at anytime. The replacement of fuses or <br /> circuit breakers with makeshift materials or over-capacity fuses is strictly prohibited. <br /> • A minimum clearance of 20 feet (radius) will be maintained between heavy equipment <br /> (i.e., drill rig) and any overhead power lines, regardless of voltage. <br /> • Before subsurface work, a utilities search for underground lines will occur and will be <br /> documented (if within 3 feet of marked underground utility, hand digging is required). <br /> • Installation and maintenance of electrical facilities or equipment must only be performed <br /> by qualified and properly authorized personnel or electrical subcontractors. Apprentice <br /> personnel permitted to work on electrical equipment shall be under the supervisoin of a <br /> fully qualified electrician. <br /> • Follow the company Lock-out/Tag-out procedures when applicable. Electrical equipment <br /> and lines shall always be considered "energized" until proven "de-energized". Before <br /> beginning work, each electrical circuit shall be inspected, tested, and where possible, <br /> isolated from the power source. Extreme care shall be exercised as wires designed to <br /> operate at ground potential may become energized by faulty or inadequate connections. <br /> • Do not wear rings, watches or metallic objects that could act as conductors when working <br /> with electrical circuits. <br /> • Do not use metal ladders and uninsulated tools while working with electrical circuits and <br /> equipment. <br /> • Protect electrical wires with suitable protective conduits or devices where they are exposed <br /> to possible damage. <br /> Electrocution—HazMit.doc Page 1 of 2 8/3/2007 <br />
