Electrical safety is an important part
of fire prevention. Thousands of
electrical fires happen every year.
Electrical fires are caused by
different things:
1. Faulty
wiring
causes
electrical fires
2. Frayed wires often ignite
other objects
3. Sometimes people place
combustibles too close to
electrical appliances

5. Write down

Causes of electrical fires:
faulty wiring-неисправная
электропроводка
frayed wires-изношенная проводка
combustiblesлегковоспламеняющиеся вещества

part of installations when the power is on.
3. Low accuracy of measurement is (an advantage, a
disadvantage) of the measuring device.
4. The danger of electric shock (increases, decreases) in

13. Check your answers(Ex.3)

1. appears / live
disappear/dead
2. unearthed/power is on
3. disadvantage
4. increases

14. Electrical safety

Following a few simple safety rules can save your
life. To reduce electrical safety hazards always
-de-energize power sources before working
with electrical equipment
-follow lockout\tagout procedures
Remember: all electricity, including static
electricity, can be dangerous. Never take risks.

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
shock.
3.Control safety system of earthing.
4. Hang out prohibitive marks.
