This extreme pH is used the destroy the stains in clothes.When we apply it on burns it causes irritation in our wounds.It might be very danger.
2.If electrical wires are not covered with plastic there is a high risk of shock.plastic is an insulator which does not allow electric current to pass through it.Hence plastic makes us safe while using electrical wires.
