When electric current flows across our body normally at a voltage higher than 90 volts, we experience a shock because the speed of electric current and the speed of blood flow in our body is not the same because We know that the speed of electric current is much higher than the speed of blood flow in our body due to which we experience tremors.
In order to reduce the impact of electrical shock, the supply voltage is kept 110v in ships, airplanes and aircraft etc.The shock to a person depends on how much amount of electric current has been flowing from that person's body. That is, if 10 mA of current 3-4 sec. By the time it flows, a person can die.
To avoid electrical accidents, we should know all the safety measures and follow the safety signs in the workshops. Also we should know the types of fire so that we can use fire extinguishers according to the type of fire.
Fire extinguishers must be available in every workshop as it is necessary to prevent fire in the workshop due to electrical short-circuit or any other reason.
