# Electrical Safety

In this worksheet, students will consider electrical safety inside and outside the home.

Key stage:  KS 2

Curriculum topic:   Electricity

Curriculum subtopic:   Common Electrical Appliances

Difficulty level:

### QUESTION 1 of 10

Useful machines in our homes and at school use a lot of energy or power. For this reason, we plug them into the MAINS ELECTRICAL SUPPLY.

Mains electricity is so powerful that it can shock, burn or even... kill!

It is very important that we learn how to stay safe, and how to keep others safe too!  Let's check it out.

Choose THREE of the options below that could complete the following sentence:

Mains electricity is dangerous because it can...........

shock

play DVDs

burn

cool things down

kill

Electricity is produced in a power station. The energy travels from the power station through overhead cables supported by pylons:

To stay safe, which TWO things must we never do near power lines?

fly kites

climb the pylon

bird watch

Which are the only TWO things which we can safely put in a socket?

pencil

screw driver

plug

plug cover

Complete the following sentence:

Electrical sockets must not be near the...........

cooker

washing machine

taps or shower

freezer

Which of the options below BEST describes why we do not have electrical sockets near taps?

water dilutes the electricity

water washes away the electricity

water conducts electricity

Complete the following sentence:

We must NEVER touch switches with...........

wet hands

dirty hands

dry hands

Complete the following sentence:

If we use appliances with damaged wires, we may get an electric.............

surprise

shock

sound

What can happen if we plug too many electrical appliances into one socket?

nothing - its OK

the socket can over-heat and catch fire

Complete the following sentence:

Trailing electrical cables are...........

untidy

too long

a trip hazard

• Question 1

Choose THREE of the options below that could complete the following sentence:

Mains electricity is dangerous because it can...........

shock
burn
kill
EDDIE SAYS
Yes, that was fairly straightforward: playing DVDs and cooling things down aren't really likely to be dangerous, are they?
• Question 2

Electricity is produced in a power station. The energy travels from the power station through overhead cables supported by pylons:

To stay safe, which TWO things must we never do near power lines?

fly kites
climb the pylon
EDDIE SAYS
It's common sense, really: massive amounts of electricity flowing through those cables, danger of death. It's a no-go area, isn't it?
• Question 3

Which are the only TWO things which we can safely put in a socket?

plug
plug cover
EDDIE SAYS
Screwdriver? Pencil? Fingers? Ouch! If something was shoved in that completed a circuit to you, then.... So, only properly designed things like plugs and safety plugs go into sockets. Right?
• Question 4

Complete the following sentence:

Electrical sockets must not be near the...........

taps or shower
EDDIE SAYS
Electricity and water are bad neighbours. That's because it's possible for water to conduct electricity. That's why you'll never find electrical sockets in the bathroom - only pull switches, so you have no chance of being part of a circuit!
• Question 5

Which of the options below BEST describes why we do not have electrical sockets near taps?

water conducts electricity
EDDIE SAYS
When the power supply is strong, water CONDUCTS electricity, making a mixture of water and electricity very dangerous!
• Question 6

Complete the following sentence:

We must NEVER touch switches with...........

wet hands
EDDIE SAYS
Only very special sockets are allowed in bathrooms because they are safe to use. Because water can conduct electricity if the power is sufficient, you never want to flick a switch if your hands are wet. That was even more dangerous in the olden days when light switches were often made of metal. Ouch!
• Question 7

Complete the following sentence:

If we use appliances with damaged wires, we may get an electric.............

shock
EDDIE SAYS
Yes, electric shocks come when you become a part of the circuit.
• Question 8

What can happen if we plug too many electrical appliances into one socket?

the socket can over-heat and catch fire
EDDIE SAYS
It can be very dangerous to 'over-load' a socket with too many plugs. Everything gets really hot and could catch fire. In fact, you may be surprised to learn that the #1 reason for house fires is an electrical fault. Definitely worth making sure it's all safe!
• Question 9

Complete the following sentence:

Trailing electrical cables are...........

a trip hazard
EDDIE SAYS
It's so easily done, isn't it: you plug in your charger, leave the cable lying across the floor and next moment someone's tripped over it, damaging the connector and, possibly, their nose when they hit the floor! Stay safe around electricity!
