Two situations were very unusual (a blind person walking into flames and an 87 year old being caught in flames on opening a cupboard). Of people 65}75 years, two with blood alcohol readings of and g/100 ml 華北水利水電學(xué)院畢業(yè)設(shè)計(jì)（論文）31started the re (one lighting matches and one falling over a radiator in a room with a high re load) and three inebriated men responded in a way that increased the danger to themselves: 70 years, g/100 ml, sat and continued drinking after being shown fire and told to leave 66 years, tried to fight fire (explosion),extinguisher had no propellant 66 years, g/100 ml, entered room of fire origin to get object of personal value. Returning to consider the whole sample, most of the victims who moved at all were attempting to escape and were overe by smoke. Only two actually exited the dwelling (one returned).Movement speed is likely to have been affected by the intake of carbon monoxide and other gases prior to noticing the fire as well as by the other conditions present. In just over 75% of cases the victims were dead when located by firefighters (. were not hospitalized). Three quarters of those asleep and half of those awake did not move from the room in which they were originally located. This suggests that people asleep succumbed to the products of fire without waking or woke too late to take effective action. (An account from a survivor rescued unconscious from his room paints the likely scenario for the latter: woken by yells, was uncertain what to do, got a lungful of smoke and woke up in hospital.) The people awake who remained in the room where the fire started were three children playing with matches, two people in a gas explosion, three elderly people with restricted mobility 華北水利水電學(xué)院畢業(yè)設(shè)計(jì)（論文）32and a 29 year old with an extensive psychiatric history, an alcohol reading of g/100 ml and therapeutic levels of medication for depression. All nine were engaged in actions that brought them into direct contact with flames. Against the author’s expectations, no differences are discernible in relation either to being asleep or to cue reception and recognition for those with alcohol readings over with others in the 1875 year age group. The effect of alcohol on waking behaviour is presumably hidden because the group is being pared with other high risk groups whose response is similar. The effect of alcohol on waking response needs to be demonstrated through experimental evidence.There is considerable danger in retrospectively judging actions taken in response to awareness of fire when the viewpoint of the victim is absent (consider the misuse of panic as an explanation for behaviour in fire, particularly for nonsuccessful actions) but the data suggest that alcohol may impair judgement regarding appropriate seeing flames and being warned by outsiders.

Focusing attention on an intermediate goal rather than on self preservation increases danger .The only other instances where escape was consciously delayed involve altruistic behaviour in family units where people were helping others and three 華北水利水電學(xué)院畢業(yè)設(shè)計(jì)（論文）33victims over 70 years who attempted to fight the fire, action that was inappropriate given their physical state and the fire conditions. (Fighting fires is an unusual response in these fires because of the stage of fire development at the time of discovery.) As it is not so unmon for people to take action which endangers their lives further, but which they remain unaware of even after the incident, the interrupting of evacuation may not be so unusual.
