Along with the influence of intense self anxiety, situations such as easily causing confusion, be crowded, trampling or even jumping out of the building, further expansion
Casualties.
China's fire-fighting emergent rescue outfit and Development of High-rise Buildings serious unbalance at present, are in particular in: the act 1. equipped
High and long shot lags behind the high development of skyscraper, the sprinkling fire and cloud that professional fire brigade 5 most of at present is equipped with
The ability maximum that elevates of the fire-fighting equipments such as tower wagon is only 15 floors, and for higher fire of high-rise building, these rescue outfits are only
Energy " watchtower is heaved a sigh "；2. the bulky, mobility equipped is poor, influenced seriously by road traffic, building surrounding enviroment, it is frequent because
With a varied topography, obstacle the reasons such as stops and misses an opportunity because of a delay；3. be equipment rescue ability it is poor, existing motor ladder is once gone up and down can only
2 to 3 people are succoured, once meeting wildfire, are not able to satisfy live practical rescue needs, the unit time personnel amount of rescue has
Limit；4. being that elevating fire truck occupied area is larger, preliminary preparation needs to expend the time, and the time is exactly to give birth to during the disaster relief
Life, most preferably rescue time sensitive.
