What safety checks should be done before attacking a fire are as follows:
1, check whether to wear flame retardant headgear.
2, check whether the combat uniform wearing standardized (pulling on whether to pull on, whether the collar is glued, whether the combat uniform thumb buttons set on the thumb).
3. Check that headlamps are turned on.
4. Check that the pager is turned on.
5. Check the air respirator pressure and estimate the time of use.
6, check the walkie-talkie channel, signal and power, test the communication effect.
Hazardous chemical accident disposal before the "eight don't forget"
1, don't forget the safety distance and the correct parking (to ensure a safe distance, from the upwind direction, avoiding sewers, manhole covers and air obstacles);
2, don't forget the traffic control and prohibit ignition sources;
3, do not forget to wear chemical suits and air respirators according to the level;
4, do not forget to wear anti-static underwear and cotton gloves;
5, do not forget to use non-sparking tools;
6, do not forget to use explosion-proof walkie-talkies;
7, do not forget to carry explosion-proof lights;
8, do not forget to do a good job of frost protection ( Disposal of cryogenic liquids, liquefied hydrocarbons and compressed gases when the accident).
In the building fire, to determine the part of the fire and the scope of the fire is to arrive at the scene to carry out fire reconnaissance, an important part of the initial assessment, is usually the first step in the development of action plans. But if the fire building only see smoke and no flame, especially when the smoke from more than one mouth out, to determine the site of the fire is more difficult.
In this case, perhaps the most effective way to locate the fire, control it and ultimately extinguish it is to enter the building and conduct an interior attack.
Traditional concepts, generally believe that the fire to the part of the water, mainly in view of the previous fire did not spread so fast, coupled with protective equipment to protect, and there is a misunderstanding of the thinking that the water vapor produced by water injection will burn firefighters or trapped people.
The actual situation? Now the residential building fire high fire load, fire development and spread much faster than before, basically from 4 to 4.5 minutes after the fire can be developed to the boom combustion, in this case, even if the firefighters with firefighting protective clothing may still be in fear of their lives.
