Electrical Safety Quiz

What is the first step in the process of electrical safe isolation?

• Testing the circuit

• Identifying the circuit to be isolated

• Locking off the circuit

• Using personal protective equipment

Which device is commonly used to lock off an electrical circuit during isolation?

• Circuit breaker

• Padlock

• Fuse

• Insulation tape

What should be used to verify that a circuit is de-energised before working on it?

• A multimeter

• A test lamp

• A voltage indicator

• A continuity tester

Why is it important to use a proving unit when testing a voltage indicator?

• To ensure the voltage indicator is working correctly

• To measure the current in the circuit

• To check the resistance of the circuit

• To calibrate the voltage indicator

What is the purpose of using a lockout tag during electrical isolation?

• To indicate the circuit is live

• To provide a warning that the circuit is isolated

• To measure the voltage in the circuit

• To identify the type of circuit

Which regulation outlines the requirements for electrical safe isolation in Great Britain?

• The Electricity at Work Regulations 1989

• The Health and Safety at Work Act 1974

• The Control of Substances Hazardous to Health Regulations 2002

• The Management of Health and Safety at Work Regulations 1999

What should be done if a circuit cannot be locked off during isolation?

• Use a warning sign

• Use a temporary barrier

• Use a lockout tag

• Use a combination of methods to ensure safety

What is the recommended minimum distance to maintain from live parts when working on an isolated circuit?

• 1 foot

• 2 feet

• 3 feet

• 4 feet

What should be done after completing work on an isolated circuit before re-energising it?

• Remove all tools and equipment

• Inform all personnel that the circuit is being re-energised

• Remove lockout devices and tags

• All of the above
