CASE STUDY 3 - ELECTRICAL SAFETY
The defective insulation hazards Introduction An electrical hazard is a dangerous condition where a worker can or does make electrical contact with energized equipment or a conductor. From that contact, the person may sustain an injury from shock, and there is a potential for the worker to receive an arc flash (electrical explosion) burn, thermal burn or blast injury. Improper grounding hazards A damaged live power tool that is not grounded or double-insulated is very dangerous! When an electrical system is not grounded properly, a hazard exists. The most common OSHA electrical violation is improper grounding of equipment and circuitry. Grounding is the process used to eliminate unwanted voltage. A ground is a physical electrical connection to the earth. Electrical equipment must be properly grounded. Grounding reduces the risk of being shocked or electrocuted. The ground pin safely returns leakage cu...
