Requirements
Service and repair
• Inspections, service, and repairs are only allowed when the portable cable is
disconnected from the power supply.
• Work must be performed by trained personnel (preferably the manufacturer or
agent) to ensure that the pump is restored to its original state of safety in regards
to all flame-arresting paths.
• Replacement parts must be exactly equal to those provided by the manufacturer.
• When cable entries are disturbed on pump or control, they must be reassembled
in the approved manner.
CAUTION: Explosion/Fire Hazard
Failure to restore the permissible equipment to its original state
of safety will void the MSHA approval. The creation of a safety
hazard will subject the owner / operator of a mine to citations and
penalties under the law.
Fastenings
All bolts, nuts, screws, and threaded covers must be properly tightened and secured.
Cables
A flame-resistant portable cable must be used. It has to bear an MSHA-assigned
identification number and be adequately protected by an automatic circuit-
interrupting device. Special care must be taken in handling the cable to avoid
mechanical damage and wear.
Operation

equipped products must not be operated dry in hazardous areas.
1.5 Special hazards
Working in temporary installations
Certain industries, such as mining or construction, have a dynamic nature and require
temporary installation of equipment. Due to the rugged nature of these applications,
normal use of electrical equipment causes wear and tear that can result in insulation
breaks, short-circuits, and exposed wires. To maximize safety when using the unit in
rugged applications, the following conditions must be met:
• If electrical cables must be located such that they are at risk of being run over by
heavy equipment, then provide mechanical protection to prevent physical damage to
the cables.
• Visually inspect electrical equipment before use. Remove from service any equipment
with exposed wires or visible damage.
• Use ground-fault circuit interrupters on all receptacles, or have an assured equipment
grounding conductor program.
