- Health and Safety at Work Act 1974
- Building Regulations Part L
- The Gas Act 1986
Correct answer: Gas Safety (Installation and Use) Regulations 1998
The Gas Safety (Installation and Use) Regulations 1998 (GSIUR) make it a legal requirement for anyone carrying out gas work to be a member of a recognised Gas Safe scheme in Great Britain.

- The engineer's name, registration number, card expiry date and the types of gas work they are qualified to carry out (Correct answer)
- Only the engineer's name
- Only the company they work for
- Only their gas safe number
Correct answer: The engineer's name, registration number, card expiry date and the types of gas work they are qualified to carry out
The Gas Safe ID card shows the engineer's photo, name, registration number, expiry date, and the specific appliance and pipework categories they are competent to work on (listed on the reverse).
Question 3: What is the penalty for carrying out gas work without Gas Safe registration?
- An unlimited fine and/or up to six months imprisonment (Correct answer)
- A £100 fixed penalty notice

Correct answer: An unlimited fine and/or up to six months imprisonment
Under the GSIUR, illegally carrying out gas work without registration can result in prosecution, an unlimited fine and/or up to six months imprisonment on summary conviction.
Question 4: What is an 'immediately dangerous' (ID) situation under Gas Safe procedures?
- A gas fitting or appliance where there is an immediate risk to life if it continues to operate (Correct answer)
- A situation that may become dangerous in the future
- Any gas leak, regardless of size
- Any appliance over 10 years old
Correct answer: A gas fitting or appliance where there is an immediate risk to life if it continues to operate
An immediately dangerous situation is one where a gas fitting or appliance presents a direct, immediate risk to life (e.g., severe gas escape, major CO emission, no flue). The engineer must make it safe without delay.
Question 5: What must a Gas Safe engineer do if they find an immediately dangerous situation?
- Turn off and disconnect the appliance or supply, label it 'do not use', and issue a warning notice; advise the owner not to use it (Correct answer)
- Carry out the repair immediately before leaving
- Advise the owner to call the gas emergency line only
- Complete a risk assessment before acting
Correct answer: Turn off and disconnect the appliance or supply, label it 'do not use', and issue a warning notice; advise the owner not to use it
When an ID situation is found, the engineer must immediately make the installation safe (isolate, disconnect or cap), label it clearly as dangerous, issue a Gas Safe warning notice and advise the owner not to use it.
Question 6: What is an 'at risk' (AR) situation under Gas Safe procedures?
- A situation that is not immediately dangerous but could become dangerous if not addressed — the engineer should advise the user to have it repaired promptly (Correct answer)
- A situation requiring immediate shutdown
- A situation only relevant to commercial installations
- A situation that requires no action
Correct answer: A situation that is not immediately dangerous but could become dangerous if not addressed — the engineer should advise the user to have it repaired promptly
An 'at risk' situation is a gas fitting that is not immediately dangerous but has a defect that could become dangerous. The engineer advises the customer to arrange repair promptly but does not immediately disconnect.
