Fight with smoke

Evacuation by recent fire is not fight with flame with increase of new kinds of building materials and plastic; with smoke fought.

Fire looks on-site

Toxic substance in smoke, terror of carbon monoxide poisoning

We include toxic substances such as hydrogen chloride, hydrogen cyanide, ammonia in smoke in many cases. Above all, there are the most quantities of outbreak, and it is carbon monoxide (CO) that we are common even if anything burns, and occur.
There are many people who almost breathe smoke not what died because of burn, and were attacked by flame when we become unconscious when we look at fried dead person. Terror of carbon monoxide poisoning causes symptoms such as headache or convulsions in extremely a very small amount of density as we know from table and disturbs evacuation from fire and is to result in death in a short time. Therefore, it is important not to breathe smoke when we evacuate from fire.
Not only fire, carbon monoxide poisoning occurs in everyday life. For example, it is necessary to perform usage and maintenance appropriately as carbon monoxide poisoning occurs by incomplete combustion with used gas appliance or oil stove.

Atmospheric carbon monoxide (CO) density and poisoning symptom (we quote from Japan gas oil apparatus industry society homepage)
CO (%) Breathing time and symptom
0.02% Headache that is light before 2~3 time
0.04% Rear headache in headache in 1~2 time in front, 2.5~3.5 time
0.08% We faint in headache, dizziness, nausea, two hours in 45 minutes
0.16% We faint in headache, dizziness, nausea, two hours in 20 minutes
0.32% Lethal in headache, dizziness, 30 minutes in 5~10 minute
0.64% Lethal in headache, dizziness, 10~15 minute in 1~2 minute
1.28% We die from 1~3 minute

The risk of smoke

  • Prospect gets worse and gives a sense of fear.
  • Fine particles enter pulmonary cell and suffocate.
  • Heat flow causes respiratory burn.
  • We include poisonous gas.
  • Ascent of smoke is rapid.

Ascent of smoke speed becomes 3m - 5m per second. As this exceeds far the speed (about 0.5m per second) that people rise on stairs, you must be careful

Point of evacuation

  • We cover nose and entrance with towel and handkerchief not to breathe smoke.
  • When it is wound up to smoke and loses evacuation route at the time of blackout of underground shopping center, we confirm instruction light, instruction mark and leave for evacuation Exit.

We show instruction light

  • As we are not shut in even if fire prevention door and fire shutter operate, we never pass through shutter which is about to close. We open fire prevention door without being upset or, in the case of shutter, evacuate from there as we pass near by, and there is door.
  • When view does not work with smoke, we put hand on floor and wall and evacuate to crawl. (as smoke collects from room, smoke is thin, and view and atmosphere remain in the neighborhood of floor)
  • It prevents it from stopping at corner of half-landing and corridor as it becomes trouble of smooth evacuation.
  • As fresh air may still remain at corners of stairs in smudge in start of floor and wall and furniture when breathing is hard, we evacuate while breathing the air.

Smoke collects from ceiling and is divided into layer of smoke and range of air. In the layer of air close to floor, smoke is relatively thin, and air and view remain.

We show place where atmosphere remains
Place where atmosphere may remain

When we evacuate on stairs, we lower posture in the same way and avoid range of smoke and evacuate.

  • As pervasive stairs of smoke may become chimney of smoke and heat, poisonous gas, stairs full of smoke do not use for evacuation.
  • We evacuate calmly to be in danger of falling down when we run at the time of evacuation without running without any reason.
  • To do deep breathing, and to breathe in a lot of smoke, big without any reason; speak, and do not make noise in a hurry.
  • We never come back once in building if we evacuate.
  • If evacuation is completed, we introduce the situation of evacuation such as having escape delay or not into fire brigade.
