Fire Prevention & Emergency Planning

What is a Hot Work Permit and when is it required?

• AA seasonal weather advisory that applies only when site temperatures exceed twenty five degrees
• BFor work involving open flames, hot surfaces, or sparks; authorises precautions before work begins✓
• CA retrospective form completed after welding or cutting work has already finished for the day
• DAn informal note in the site diary that the foreman updates whenever he personally feels like it

Answer: Hot Work Permits are required for welding, cutting, grinding, and any process generating heat/sparks. They authorise fire prevention measures before work starts.

What precautions must be taken before hot work begins?

• APrecautions are necessary when working inside occupied buildings rather than on open sites
• BRemove combustibles, establish fire watch, position extinguishers, check for enclosed spaces, post-work checks✓
• CKeep a single bucket of water nearby, inform a colleague verbally, and assume that is sufficient before welding or cutting begins
• DPrecautions are the sole responsibility of the operative on site and do not require a supervisor's sign-off first

Answer: Hot Work precautions: clear combustible materials within 10 metres, assigned fire watch for at least 60 minutes after work, extinguishers at hand, and testing for internal combustion hazards.

What is a fire risk assessment?

• ASystematic evaluation of fire hazards, likelihood, and consequences; identifies preventive and protective measures✓
• BA record kept solely for insurance purposes with no bearing on day-to-day site fire safety
• CA one-page checklist completed once at the very start of a project that is filed away and never reviewed, updated, or referred to again
• DA generic template downloaded from the internet and filed away without site-specific detail

Answer: Fire risk assessments identify hazards (hot work, flammable materials, electrical), evaluate likelihood, and document preventive measures and escape routes.

What should an on-site emergency evacuation plan include?

• AAssembly point, muster procedures, communication methods, rescue arrangements, and specialist services contact details✓
• BA list of taxi numbers so workers can leave site quickly once the alarm has been raised
• CA weekly attendance register used only to confirm who clocked in and out of the site
• DA single laminated sign at the site entrance showing the location of the nearest fire exit and the site manager's mobile number

Answer: Evacuation plans address: safe routes, assembly point, accountability checks, communication (especially for workers who can't hear alarms), and liaison with emergency services.

What is the purpose of fire drills or evacuation exercises?

• AA box-ticking exercise carried out purely to satisfy the client's paperwork requirements before each quarterly site audit
• BTo test and improve the emergency plan, train personnel, and identify gaps before a real emergency✓
• CA one-off event held during initial site induction that is not formally repeated or reviewed afterwards
• DA punishment exercise used by management after workers are caught deliberately breaching site safety rules

Answer: Regular drills (recommended quarterly or semi-annually) ensure personnel understand routes, assembly points, and procedures. They reveal plan weaknesses before incidents.

What types of fires and extinguishers should supervisors know?

• ATwo classes exist on construction sites, ordinary combustibles and flammable liquids, both suited to water
• BExtinguishers on site are interchangeable, so colour coding and class markings can be ignored
• CClass A (solids), B (flammable liquids), C (gas), D (metals), F (cooking oils); correct extinguisher type per class✓
• DFire class matters in commercial kitchens and has no relevance to construction site hazards

Answer: Fire classes determine extinguisher types: Class A = water or foam, Class B = foam or powder, Class C = powder, Class D = specialist powder, Class F = wet agent.

What should be done to prevent electrical fires on construction sites?

• AInspect cables, use RCDs, avoid overloading circuits, keep water away from electrics, and remove damaged equipment✓
• BTemporary site supplies are pre-tested once by the electrician and need no further inspection
• CRely on the main circuit breaker tripping automatically, since modern site wiring rarely faults or overheats in practice
• DReplace all mains power with battery-operated tools instead, which completely removes any possibility of an electrical fire

Answer: Electrical fire prevention: damaged cables must be replaced, overloaded circuits avoided, RCD protection used for hand tools, and damp areas properly managed.

What fire prevention role does a supervisor have regarding site practices?

• AFire prevention is built into the building design from the outset, so supervisors need to check it once at handover
• BThe appointed fire marshal holds the fire prevention duties, not the site supervisor
• CSupervisors simply call the fire brigade once smoke or flames are noticed on site
• DEnsure no smoking near materials, manage hot work permits, keep escape routes clear, remove waste accumulation✓

Answer: Supervisors enforce: smoking bans, hot work controls, clear escape routes, timely waste removal, and proper storage of flammable materials.

What is first aid provision and the supervisor's responsibility?

• AFirst aid is legally administered by a paramedic called out from the local hospital, so site first aiders are not needed
• BFirst aid arrangements are the responsibility of the client, not the site supervisor
• COptional until fifty workers are employed on a single site at one time
• DEnsure trained first aiders, accessible first aid kits, communication systems, and procedures to get help quickly✓

Answer: Supervisors ensure: adequate first aid personnel on site, well-stocked and accessible first aid kits, communication systems, and coordination with emergency services.

What is an automated external defibrillator (AED) and why is it important?

• AA piece of fixed hospital equipment that cannot legally be transported to a construction site
• BPortable device used for cardiac arrest; available and accessible for cardiac emergencies✓
• CA specialist device that requires a doctor's authorisation before it can be switched on safely
• DA device useful after paramedics arrive, so having one on the site provides no real benefit

Answer: AEDs combined with CPR significantly improve survival in cardiac arrest. Large sites should have accessible AEDs with trained users nearby.

What should be communicated in emergency procedures training?

• AReading the written emergency plan posted in the site office is enough for workers on its own
• BA laminated card showing just the office telephone number pinned up in the site cabin
• CEmergency training is delivered only to directly employed staff, since subcontractors and agency workers are assumed to already know the site layout
• DAlarm recognition, evacuation routes, assembly point, accountability, first aid access, and liaison with emergency services✓

Answer: Emergency training covers: alarm recognition/response, evacuation routes (two per area), assembly point location, muster procedures, and emergency service contact.

What are the requirements for hot work permits on construction sites?

• AAuthorise hot work, confirm area clear of flammables, assign fire watch, and approve safe conditions✓
• BA verbal go-ahead from the site supervisor is sufficient authorisation, since written permits mainly apply to work carried out by contractors
• CHot work carried out on non-combustible surfaces such as concrete or steel decking carries no fire risk, so a permit isn't necessary there
• DPermits are only required for hot work lasting a full shift, not shorter jobs

Answer: Hot work permits require: inspection of the area and removal or protection of combustible materials, extinguishers to hand, a fire watch during the work and for at least 60 minutes after it ends, and written authorisation before work starts and when the permit is closed.

What is a fire watch and what are the responsibilities?

• AFire watch is only required for hot work carried out inside buildings, since outdoor work has enough natural ventilation to disperse any sparks
• BTrained person monitoring during/after hot work for fire development; must detect fire immediately✓
• CFire watch is a formality noted on the permit, replaced by smoke detectors
• DAny available worker can be assigned fire watch duty without any training at all

Answer: Fire watch must: remain alert during work, scan for signs of fire, have an extinguisher to hand, keep watch for at least 60 minutes after the work ends, and report hazards immediately.

What are the hazards of LPG storage on construction sites?

• ALeakage, explosion, and fire risk; requires secure storage, leak detection, and distance from ignition sources✓
• BLPG cylinders can be stored wherever is convenient, since small leaks disperse harmlessly outdoors
• CLPG is a stable, non-flammable gas, so it presents little fire or explosion risk on site
• DStandard steel containers store LPG safely without extra ventilation or signage requirements

Answer: LPG storage must be: secure (locked cabinet), away from ignition sources (10m+), in ventilated area, labelled, leak-tested regularly, and empty cylinders segregated.

What should a site fire plan include?

• AA fire plan needs one marked route at the site entrance gate
• BA written fire plan is a legal requirement on sites larger than a defined floor area, so smaller sites can rely on verbal instructions
• CEscape routes, assembly points, alarm systems, fire equipment locations, and emergency contact numbers✓
• DFire plans mainly apply to permanent buildings, not fast-changing sites

Answer: Site fire plans detail: marked escape routes (two per area minimum), assembly point location, alarm recognition, emergency contact numbers, and periodic drill frequency.

What fire risks exist in temporary accommodation on construction sites?

• ASite cabins need a single fire inspection when first installed, since conditions rarely change
• BFire regulations for permanent buildings don't apply to temporary site accommodation units
• COvercrowding, electrical overload, blocked exits, and flammable materials; requires inspections and protocols✓
• DPortable cabins are built from fire-resistant materials, so they carry negligible fire risk

Answer: Temporary accommodation risks: inadequate exits, electrical hazards, blocked corridors, and combustible contents. Regular inspections, clear routes, and alarms mandatory.

What fuel storage and handling safety measures are essential?

• AFuel drums can be left in their delivery position anywhere on site, since modern containers are sealed tightly enough to prevent spillage
• BSecure containers, secondary containment, distance from sources, proper labelling, and spill management✓
• CFuel containers need to be kept off bare soil, with no other rules applying
• DStorage location makes little difference, since the real hazard comes from handling it

Answer: Fuel is kept in a secure, lockable tank, bowser or store with secondary containment, such as a bund or drip tray (for a single tank, at least 110% of its capacity). It is sited away from ignition sources, drains and watercourses and protected from vehicle impact, containers are clearly labelled, and a spill kit is kept to hand with operatives trained to use it.

What is COSHH and how does it relate to fire prevention?

• AControl of Substances Hazardous to Health; it covers health risks, while fire risk falls under DSEAR✓
• BCOSHH applies to manufacturing chemicals, not substances stored on site
• CControl of Substances Hazardous to Health; its assessment replaces the fire risk assessment for solvents
• DCOSHH covers substances brought to site in quantities over 25 litres, not small tins

Answer: COSHH 2002 controls risks to health, such as breathing solvent vapour. It does not apply where a substance is hazardous only because it is flammable or explosive (reg 5(1)(b)): those fire and explosion risks fall under DSEAR 2002, which requires a risk assessment, safe storage and control of ignition sources. A COSHH assessment does not replace the fire risk assessment.

What training must supervisors provide on fire prevention?

• AInduction covers fire hazards, emergency routes, assembly point, equipment use, and roles during evacuation✓
• BFire prevention can be left out of induction if a site already displays evacuation signage clearly
• CFire prevention training is only required for hot work like welding
• DWorkers are expected to pick up fire safety awareness informally, since formal training adds little value

Answer: Fire prevention training covers: site hazards, evacuation procedures, alarm recognition, extinguisher types, and individual responsibilities during emergencies.

What emergency contact information must be prominently displayed on construction sites?

• AEmergency contact details only need to be kept in office files
• BPosting emergency information is left to individual site managers' preference, since workers are expected to know local emergency numbers already
• CEmergency services numbers, site emergency contact, first aid officer location, and assembly point✓
• DA single notice on the site office door with the emergency number is sufficient for most workers

Answer: Display at: site entrance, offices, welfare areas, and work areas: emergency services (999), site coordinator contact, first aider name/location, assembly point location.
