Elevators do not have fire safety conditions in General, fire cannot be dispersed using a straight line, the main reasons are as follows:
1, power supply is no guarantee. Due to the attack of fire, firefighters need to intercept all the normal operation of the power supply and emergency power supply.
2, attack the chimney effect. Due to the lift, lift shafts will lose the smoke effect, into pulling smoke drawing fire straight path, both grow extending Fireworks dispersed, threatening people's lives.
3, the spread can be limited. When a fire attack, lift can carry more than 10 at a time their own, the rest will have to wait and so will delay dispersion time.
4, if the passenger elevator attacks mechanical and electrical faults (or power outage), decentralized personnel will be trapped in the elevator and unable to escape.
