Hint: Electrical safety is a system of structural measures and technical means to intercept damaging and dangerous effects on workers and the appliances from electric current, electric arc, electromagnetic field and static electricity.
Complete step by step solution:
Two safety measures commonly used in electric circuits and appliances are:
Electric Fuse:
In electronics, a fuse is an electrical protection apparatus that operates to provide overcurrent protection of an electrical circuit. Its important component is a metal wire or strip that melts when too much current flows through it, thereby stopping or breaking up the current. It is a sacrificial apparatus; once a fuse has operated it is an open circuit, it has to be replaced or rewired, depending on type.
Earthing:
Earthing is performed to safeguard us from an electric shock. It performs this by providing a path that is a protective conductor for a liability in current to flow to earth. It also causes the protective device that is either a circuit-breaker or fuse to shut down the electric current to the circuit that has the liability.
Miniature Circuit Breaker (MCB):
The MCB instinctively switches OFF electrical circuits during any uncommon condition in the electrical network such as overload & short circuit conditions. However, the fuse can sense these conditions but it has to be replaced though MCB can be reset.
Note: Training employees in order to work safely around electrical units is a critical need for sustaining the worker's safety. Electricity is a dangerous workplace hazard that can result in serious injuries and even death if your workers are not properly trained.
