Q

History of responsiblity for fire services and stats

A
  • After 2000, responsibilities for these changed to the Department for transport, local government and the regions (DTLR).
  • In 2002, this changed again to the office of the deputy prime minister (OPDM).
  • After the infamous “John Prescott affair”, the OPDM was abolished in 2006 and the majority of its responsibilities were migrated to the department for communities and local government (DCLG). This included the fire and rescue service.
  • Finally, in January 2016 responsibility for fire and rescue policy in England reverted back to the home office.

Care needs to be taken when looking at statistics.

The way fires are measued is subjective

Q

What does fire stats help us monitor?

A
  • Fire statistics help us to monitor the number of, and the characteristics of fires attended by UK fire brigades. It also allows for consideration of the causes and effects of fires so that future action can be taken to reduce the human (and financial) costs of fires.
  • It also helps promote awareness and educatin in public.
  • The overal goal is to reduce the incidence of fire and related deaths

Q

Where do the majority of fire related deaths occur?

A

Dwellings (houses, flats, etc)

17
Q

What type of home doesn’t have a clear category in fire data?

A

Motor homes

18
Q

What is the trend for number of fatalities?

A

They are decreasing and appears to be plateauing however there isn’t enough data to support this.

19
Q

Why are their abnormalities for 2017 data

A
  • 2017 was an anomaly due to Grenfell, which has been accounted for but due to its severity has been given an individual data set as well as being added to the cumulative figure.
  • This is help us appreciate the normal observed trend.
20
Q

Why is there a decrease in non fatal casualties after 1996 despite it increasing before this?

A
  • Smoke alarms were made mandatory, which meant that smoke alarm ownership had a huge growth spurt, and almost perfectly intersects with the reduction of casualties we observe.
  • When legislation comes into place it takes a while to implement them leading to a lag effect of the acceptance of the legislation
21
Q

Largest ignition for accidental dwelling fires.

2021

A

Cooking appliances were the largest ignition category for accidental dwelling fires, accounting for 46 per cent of these fires and 35 per cent of non-fatal casualties but only accounted for 10 per cent of the fire-related fatalities

22
Q

Accidental dwelling fires

A
  • The primary reason for fire in homes is the misuse of equipment
  • The data can’t show the extent of the damages caused
  • The incident occurrence / the reason of the fire can have an effect on the extent of the damage
  • Common occurrence but relatively they’re not that deadly
  • Smoking materials are far more fatal but less occurrence
23
Q

Why is the a decrease in chip pan fires?

A
  • Chip pan fires make up 6% of all fires, they used to make 20% of all incidents.
  • The reason for this is we have gotten healthier as a nation!
24
Q

Effect of smokers on the decreasing trend in accidental dwelling fires

A
  • There has been a reduction of smokers from 2001 to 2015.
  • Fewer people are smoking which means fewer opportunities for ignition.
  • UK regs have made smoking itself less likely to cause a fire. Cigarettes now have a less porous portion of the paper that acts as a break in the cigarette. It won’t go through and burn past it unless you actively are drawing the air through it.
  • More people have begun vaping which removes fuel package.
25
Q

Effect of alcohol and drugs

A
  • 7% of accidental dwelling fires linked to booze + drugs in 2016/17
  • More impaired = bad judgement and careless
  • Drinking is a downward trend, Pubs have been closing.
  • People are drinking less frequently so we are seeing a downtake in related fires caused
26
Q

How has legislation affected fires?

A
  • In 1988, there were regulations about furnishings. So if you buy a sofa or curtains, there will be laws about how it should be treated for fire retardant to prevent the spread of fires.
  • In 1992, there were laws introduced about smoke alarms for rental properties and for any other public building.
  • Escape windows were introduced in 2000
  • in 2005, there was electrical standards introduced. People are aware that they were cheap electronics coming into the country, And some of these would have poor Connections, and those connections would start to fire.
  • Sprinklers were introduced in 2006
27
