HAZARD MITIGATORS — ELECTROCUTION * A minimum clearance of 12 feet (radius) will be maintained between heavy equipment (i.e., drill rig) and any overhead power lines, regardless of voltage. * Before subsurface work, a utilities search for underground lines will occur and will be documented. * Installation and maintenance of electrical facilities or equipment must only be performed by qualified and properly authorized personnel or electrical subcontractors. Apprentice personnel permitted to work on electrical equipment shall be under the surveillance of a fully qualified electrician. * Electricians shall be familiar with the National Electrical Code; state and local electric codes; OSHA standards, including 29 CFR 1926, Subpart K; and applicable sections of the National Fire Protection Association Codes. * When working on energized circuits of 440 volts or higher, at least one qualified electrician and one other employee shall be present. * Do not wear rings, watches or metallic objects that could act as conductors when working with electrical circuits. * Do not use metal ladders and un -insulated tools while working with electrical circuits and equipment. * Follow the company Lock-out/Tag-out procedures when applicable. Electrical equipment and lines shall always be considered "energized" until proven "de -energized". Before beginning work, each electrical circuit shall be inspected, tested, and where possible, isolated from the power source. Extreme care shall be exercised as wires designed to operate at ground potential may become energized by faulty or inadequate connections. * Use only approved grounding equipment as a ground for electrical equipment. Metal frames on electricity powered equipment, electrical facilities, and transmission equipment shall be connected to the grounding system. Alternative grounding systems complying with applicable electrical codes may be used for temporary portable equipment. * Protect electrical wires with suitable protective conduits or devices where they are exposed to possible damage. * Connect grounding devices to a ground before contacting any conductor of a circuit. When grounding devices are removed, they shall be disconnected from the circuit before being disconnected from ground. * Equip all portable extension cords with a non -conducting plug and/or another socket shell. All electrical cords shall be equipped with three -blade grounding type plugs. Hazard Mitigators — Electrocution 9/1/2015
