Control measures of electrical equipments
Various protective systems can be used for electrical equipment such as:
- Fuses - a weak link in the circuit
- Earthing - a low resistance path to earth for fault current
- Isolation - cutting the power
- Reduced and low voltage - so that less current flows during an electric shock accident
- Residual current devices - sensitive and fast acting trips
- Double insulation - separating people from the conductors using two layers of insulation
Control measure to reduce the risk of electrical shock when using a portable electric drills
- Reduce voltage operation
- Use of residual current circuit breakers
- Protected against overload
- Insulated cables
- Adequate maintenance and repair
- Regular inspection and checks (portable appliance testing)
- Avoid use in wet environment
- Wearing of proper ppe such as rubber gloves, rubber sole shoes
- Competent staff
Emergency action to take if a person suffer a severe electric shock
Do not touch injured person until the current is switched off; If power cannot be switched off, stand on some dry insulating material and use a wooden or plastic rod to remove the injured person; Administer first aid if qualified; Call for professional help
Effects on the human body from a severe electric shock
- Damage to the nervous system
- Fibrillation (irregular heartbeat)
- Tissue burn at entry and exit
- Internal burns
- Physical trauma-from being thrown down
