Unsafe Situations

What defines an 'At Risk' classification?

• AA defect that poses potential danger but is not immediately life-threatening✓
• BA term that the gas industry's unsafe situations procedure does not actually use
• COnly for obvious hazards
• DJust observations

Answer: At Risk situations could become dangerous and require remedial action.

What defines an 'Immediately Dangerous' situation?

• AA condition posing imminent risk of injury or death requiring urgent action✓
• BA minor defect that should simply be noted on the record for attention next year
• CA warning given verbally to the customer, with no further action being required
• DAny fault found during a routine annual service visit

Answer: Immediately Dangerous situations require urgent isolation and warning.

What must be done with an Immediately Dangerous appliance?

• AContinue using the appliance with care until a replacement part can be obtained
• BSchedule repairs for the next available appointment, and leave it in service
• CWith permission, disconnect it, label it DO NOT USE and issue a warning notice✓
• DReport it to Gas Safe Register and take no action on site

Answer: An Immediately Dangerous appliance is disconnected with the responsible person's permission, labelled DANGER DO NOT USE and recorded on a warning notice. If permission is refused, the engineer calls the Gas Emergency Service on 0800 111 999 for natural gas.

What is a 'Not to Current Standards' (NCS) defect?

• AA dangerous condition which requires the appliance to be disconnected from the supply at once
• BAn At Risk situation that must be turned off with the owner's permission
• CAn acceptable variation which needs no entry on the record and no advice given to the customer
• DAn installation that is safe but does not meet the current standard, such as BS 6891✓

Answer: Not to Current Standards is no longer an IGEM/G/11 unsafe category. The engineer may advise the customer, but no warning notice is issued. It describes an installation that is safe but was built to an older standard.

What is a warning notice in gas safety practice?

• AAn informal note the engineer leaves for the customer, with no official standing
• BA formal notice issued when a dangerous defect is found✓
• CA courtesy telephone call made to the customer after the visit has finished
• DA letter recommending that the customer considers replacing the appliance

Answer: Warning notices formally alert occupants to dangerous gas defects.

What should be included on a warning notice?

• AOnly the engineer name
• BNature of hazard, appliance details, why it's dangerous, and required actions✓
• CJust the date
• DThe requirements are not specified in the regulations

Answer: Warning notices detail the hazard, why it's dangerous, and what action is needed.

What is the procedure for an engineer discovering a gas leak?

• AContinue inspection
• BSchedule a repair for a later date, and leave the supply on in the meantime so the customer has heating
• CIsolate, label it DO NOT USE, issue a warning notice, and call 0800 111 999 if it cannot be made safe✓
• DJust warn the customer

Answer: A gas escape is Immediately Dangerous under IGEM/G/11. With the responsible person's permission, isolate and make safe, attach a DANGER DO NOT USE label and issue a warning notice. Call the Gas Emergency Service on 0800 111 999 if the escape cannot be found or made safe, or if permission to disconnect is refused.

What is capping off in gas work?

• ATemporary isolation of the supply by closing the appliance valve until the engineer's next visit
• BJust closing the isolation valve and leaving the open end of the pipework exactly as it was found
• CPermanently isolating and sealing a gas supply or appliance when dangerous or no longer needed✓
• DFitting a cap to the flue terminal to stop rain entering it

Answer: Capping involves permanent isolation of dangerous gas pipes or appliances.

What must be done to cap off a gas installation?

• AIt follows no particular procedure, so long as gas cannot escape
• BLeave it open
• CIsolate supply, test for tightness, and install permanent caps/plugs on all open ends✓
• DJust close the valve

Answer: Capping requires testing tightness and installing permanent seals.

What is a customer handover document?

• AA document explaining the safety status, any faults, and required actions given to the occupant✓
• BOnly for sales
• CJust a receipt
• DSomething that can be dispensed with wherever the work is routine

Answer: Handover documents inform customers of condition and any remedial needs.

What is the legal consequence of supplying gas to a dangerous appliance?

• ATelling the customer about the defect removes any legal consequence
• BCriminal liability for the engineer and potentially the supplier✓
• CWarning only
• DJust a fine

Answer: Allowing dangerous appliances to operate creates criminal liability.

What should be done if an appliance is deemed Immediately Dangerous due to CO risk?

• ASchedule a service visit for the earliest date on which the customer is able to be at home to let you in
• BWith permission, disconnect, label it DO NOT USE, issue a warning notice and explain the CO danger✓
• CMonitor the situation, asking the customer to fit a carbon monoxide alarm and report any symptoms
• DDisconnect the electrical supply and leave the gas connected

Answer: An appliance that is Immediately Dangerous from carbon monoxide is disconnected with the responsible person's permission, labelled DANGER DO NOT USE and recorded on a warning notice, with the CO danger explained. If permission is refused, call the Gas Emergency Service on 0800 111 999.

What is a landlord's responsibility if a dangerous defect is found?

• AIt is the landlord's own choice whether the repair is carried out or not
• BPass the cost of the repair on to the tenant
• CLegal obligation to carry out urgent remedial work and ensure safety✓
• DThe engineer can only make a recommendation, which the landlord may decline

Answer: Landlords must legally rectify dangerous defects promptly.

What must be documented about unsafe situations?

• AOptional documentation
• BDocumentation is not required, as long as the occupier accepts the risk
• CJust a note
• DFull details of the hazard, tests performed, classification (ID or AR), and actions required✓

Answer: Under the Gas Industry Unsafe Situations Procedure (IGEM/G/11), the record of an unsafe situation should set out the hazard, the tests carried out, its classification as Immediately Dangerous (ID) or At Risk (AR), and the action taken or required. Not to Current Standards is no longer a category in the procedure, because an installation that is merely below current standards is not unsafe.

What is the role of HSE in dangerous gas situations?

• AHSE plays no part
• BEnforcement only in commercial properties, since domestic work is unregulated
• CEnforcement of regulations and investigation of serious breaches or accidents✓
• DJust advisory

Answer: The HSE enforces safety regulations and investigates serious incidents.

What must a Gas Safe registered engineer report to HSE under RIDDOR regulation 11(2)?

• AA small gas leak found on an appliance connection during a routine service
• BAn At Risk situation found on an appliance the engineer did not install
• CA dangerous gas fitting caused by poor workmanship or design✓
• DA boiler breakdown reported by the customer during a cold spell

Answer: RIDDOR regulation 11(2) requires a registered engineer to report a gas fitting that, through its design, installation, modification or servicing, is dangerous enough to have caused or be likely to cause death, loss of consciousness or hospital treatment.

Under RIDDOR 2013, how soon must a Gas Safe registered business report a dangerous gas fitting to HSE?

• AWithin one month of the visit
• BWithin 14 days of acquiring the information✓
• CWhenever convenient, as there is no deadline
• DWithin 10 days, as for other dangerous occurrences

Answer: Regulation 11(2) of RIDDOR 2013 requires an approved person (a Gas Safe registered business) with enough information to decide that a gas fitting, or its flue or ventilation, was or could have been likely to cause death, loss of consciousness or hospital treatment through gas leakage, incomplete combustion or poor removal of combustion products to report it to HSE within 14 days of acquiring that information. The 10-day written report applies to incidents under regulations 4 to 7, such as specified injuries and dangerous occurrences, and the 15-day limit to over-seven-day injuries.

What is the purpose of a safety label on a gas appliance?

• AOptional, since the operating instructions are supplied in the manual
• BA cosmetic sticker that carries the manufacturer's brand and model name
• CRecording the date the appliance was last serviced
• DInforming users of proper operation, safety precautions, and warnings✓

Answer: Safety labels warn users and provide essential operating information.

What is corrosion as an unsafe situation?

• ASomething that poses no hazard while the pipe still holds
• BNormal ageing
• CJust discolouration
• DCorrosion weakening pipes/appliances, potentially causing gas leakage✓

Answer: Corrosion can perforate pipes, creating dangerous gas leaks.

What is mechanical damage as an unsafe situation?

• AWear to the appliance controls over years of use
• BCosmetic damage, such as dents and scratches to the appliance case
• CDamage caused by corrosion from damp over many years
• DPhysical damage to gas pipes or appliances risking gas leakage✓

Answer: Mechanical damage can create immediate gas leakage hazards.

Under RIDDOR 2013, which causes can make a dangerous gas fitting reportable by a Gas Safe registered business?

• AElectrical faults, such as a failed control board or fuse
• BGas leakage, incomplete combustion or poor removal of combustion products✓
• CAn installation that no longer meets current standards
• DAppliances that are old, generally more than 15 years

Answer: Regulation 11(2) of RIDDOR 2013 makes a gas fitting, or its flue or ventilation, reportable to HSE within 14 days where its design, installation, modification or servicing was or could have been likely to cause death, loss of consciousness or hospital treatment because of the accidental leakage of gas, the incomplete combustion of gas or the inadequate removal of the products of combustion. Nobody needs to have been hurt, and an installation that is merely below current standards is not reportable on that ground alone.

What must be checked to determine if an appliance is 'Immediately Dangerous'?

• AGas tightness, flue integrity, combustion quality, and safety device operation✓
• BSomething that goes unchecked
• CJust age
• DOnly the outward appearance of the appliance and how old the casing looks to be

Answer: Multiple checks determine whether an appliance poses immediate danger.

An installation is safe but does not meet current standards (formerly 'NCS'). How should the engineer handle it?

• AAdvice to the owner is optional and kept off any warning notice✓
• BReport the installation to the local building control office
• CImmediate isolation of the appliance and the issue of a warning notice
• DRecord it as At Risk and turn it off with the owner's permission

Answer: IGEM/G/11 now classifies unsafe installations only as Immediately Dangerous or At Risk. Not to Current Standards was removed from the procedure because such an installation is not unsafe. Gas Safe Register says an engineer may still tell the customer, if they wish, that installation requirements have changed, but this should not be recorded on a warning notice or other safety-related paperwork, and it calls for neither isolation nor an At Risk classification.

What is a recall in gas safety?

• AJust marketing
• BOnly for new products
• CA manufacturer's action to identify and remedy a safety defect in appliances✓
• DSomething that happens so seldom it can be discounted

Answer: Recalls address identified safety defects in specific appliance models.

What is the customer's right if a gas engineer finds a dangerous situation?

• ATo receive a clear explanation, warning notice, and recommendations for remedial action✓
• BTo ignore it
• CAn explanation is only owed in the most urgent cases, where the supply has actually been capped
• DThe customer has no right

Answer: Customers must be fully informed of any dangers found.

Which combination of symptoms should make you suspect carbon monoxide (CO) poisoning?

• AA high fever with a skin rash that spreads across the chest and the back over a few days
• BHeadache, dizziness, nausea and confusion that feel like flu but without a fever✓
• CSudden joint pain that worsens only with exercise and eases completely with rest
• DA blocked nose and sneezing that clear up outdoors

Answer: CO poisoning classically causes headache, dizziness, nausea, tiredness and confusion — often mistaken for flu or a viral illness, but crucially without the fever a real flu would cause. Several occupants feeling unwell at the same time, or feeling better away from the property, is a strong warning sign.

What is the correct immediate response if carbon monoxide poisoning is suspected in a property?

• AVentilate the property, turn off the suspect appliance if safe to do so, get everyone into fresh air, and call the Gas Emergency line on 0800 111 999✓
• BClose all windows to stop the gas spreading outside and wait for it to clear
• CLight a match near the appliance to check whether gas is present
• DKeep the appliance running so that the engineer can inspect it while it is still working, and keep everyone in the room

Answer: Ventilate the property, isolate the appliance if it is safe to do so, get everyone into fresh air, and call the National Gas Emergency Service on 0800 111 999. Call 999 immediately for anyone showing symptoms of poisoning, and do not re-enter the property until it has been confirmed safe.
