Revision Flashcards
What is the fire triangle?
Heat, fuel & oxygen. The three elements required start a fire
What are the main causes of accidental fire?
People Processes Heating systems Lighting & power systems Waste & materials Trade processes Other occupiers
How can heat be transferred?
Conduction
Convection
Radiation
How can fire spread by conduction?
When two bodies are in physical contact, heat can travel from one to the other via conduction which may cause the temperature to rise to its ignition point starting a fire
What affects propagation of a fire in a building?
Fire resistivity of floors, ceilings and walls
Openings such as doors & windows
Combustibility of contents
Compartmentation
What materials are prone to spontaneous combustion?
Damp hay in stacks
Grain
Piles of oily rags
Flammable liquids with low flash points like acetone & benzene
What issues are caused by poor house keeping?
Allowing fires to smoulder undetected, hindering the fire brigade, not clearing waste, dropping cigarettes. This all makes fire inception more likely
Why are flammable liquids & gasses a potential explosion hazard?
Vapoury can easily mix with oxygen in the air filling a room. When beat is added the vapours explode as the fire triangle is complete
How will a surveyor use information on flashpoint & auto ignition temperature of materials?
To assess the safety of the storage, processes & the adequacy of the fire detection & suppression systems
What do underwrites make assessments of when assessing fire hazard?
The fire load - The proportion of combustable vs resistive material within the building & the overall resistivity of the building itself
What makes q floor fire resistive?
It must be non combustible, normally made of either concrete or hollow clay blocks
How are automatic fire alarms catagorised?
Composite strip: detect rapid change in temperature
Smoke: use radioactivity to detect ionised smoke particles
Heat: detect IR or UV radiation
What are the most common sprinkler systems?
Wet
Dry
Alternate
Pre-action/ drencher
How can you mitigate the effects of a lightning strike?
An electrical conductor can be added to the buildings high points to guide the electricity through a conductive path to a discharge rod buried in the earth
What is the difference between a fire & explosion?
The speed of ignition
Why is dust a more severe hazard than gas?
Gas is free to escape & is unlikely to build up unlike dust which may float around in the air & settle in the environment providing a source of fuel
Why is location near a water course not always an indicator of flood risk?
Flash flooding is becoming much more frequent & aging drainage systems can’t cope with the high volumes of water
What type of soil is thought to present the greatest risk in terms of damage caused by subsidence?
Heavy clay soils
How is theft defined in section 1 of the theft act 1968 (England & Wales)?
Dishonestly appropriating property belonging to another with the intention of permanently depriving them of it
How does a typical theft policy wording extend the cover to include theft that does not involve breakdown of the physical defences of the building?
Theft involving violence or threat of violence to you, your partners, directors or employees. This extends theft cover to a robbery wording where the physical defences are not overcome
What type of theft cover would a hotelier require?
Full theft cover without the requirement of break in
What is the significance of risk address in theft underwriting?
Address reveals the likely incidence rate of theft
Name 3 types of perimeter protection, other than doors and windows
Lockdown posts/anti ram posts
Perimeter fencing
Strong room /cage
How are safes classified?
Free standing
Wall mounted / floor mounted
Safes are given a limit of liability for storage based on their security rating
Why are goods in transit attractive to thieves?
They are new, well packaged & easy to sell
What is the definition of damage in the standard fire & specified contingencies policy?
Loss or destruction of or damage to the property insured
If riot is insured how many days does the insurer have to pursue recovery from the police?
42
What is the difference between the terrorism cover provided is1993 f the revised 2003 version?
1993- fire & explosion damage only
2003- All risks bases, including CBNR
What are the three main components insured in a property damage policy?
Buildings
Machinery
Stock
What other costs may be incurred during reinstatement?
Professional fees
Debris removal
EU & local authority costs incurred in complying with regulations
What are the typical loads applied to building & machinery sum insureds for debris removal & complying with regulations?
Building: 17%
Machinery: 5-10%
What is the benefit of insuring rent under the BI section of a policy?
Coverage under the property damage section only applies while the building is uninhabitable while cover under the BI section also covers the period a building is unoccupied for following completion of works
What are the other principal commercial property policies other than fire & specified contingencies?
Money
Glass
Goods in transit
Engineering
What benefits for the insurer are there for a profit share / low claims rebate?
It provides incentive to renew. Rebate is only available if the policy renews
What are the main contingencies that can be added to basic fire, lighting & explosion cover?
Explosion, Aircraft, Riot, Earthquake, Spontaneous combustion, Storm, Flood, Escape of water, impact by own/3rd party vehicle, sprinkler leakage, subsidence, terrorism
Why is SRCC offered as a special contingency & excluded in the conditions?
Certain risks may be target locations ( news papers, animal testing etc) risk must be considered for every location
What schemes are available to protect insureds from underinsurance due to inflation?
Index linking
Day one basis
What sections of policy can day one basis be applied to?
Buildings & contents
When property is temporarily removed for various purposes insurers often freely provide cover. Name I describe two clauses used for this purpose
Temporary removal applies to removal of machinery & fixtures etc for cleaning I renovation/repair within the UK, including transit with a limit up to 10% of the so insured against contingencies in the policy
Temporary removal of document & computer records to premises; the UK e.g. auditors for contingencies in the policy up to 10% of the sum insured
How does inclusion of the debris removal, EU & Public authority, professional fees clauses affect the operation of the average clause?
Except for stock insurance, where the clause does not apply, the value of the property insured at the relevant time is increased by appropriate amounts for each clause. The sum insured must correctly allow for each clause value, otherwise the average clause will further reduce the amount payable.
What are the characteristics of an obsolete building?
A design/construction now impractical to reproduce or not subject to rebuild. Not suitable for the original purpose it was built
