different things:
1. Faulty
electrical fires
2. Frayed wires often ignite
other objects
3. Sometimes people place
combustibles too close to
electrical appliances

15. Safety Rules

1. Proper maintenance for wiring is very
important. Always evaluate all wires. Make
sure they are not frayed or damaged
2.Use means of protection against electric
3.Control safety system of earthing.
4. Hang out prohibitive marks.
