关于隧道中所使用的信号装置,在连续发生几起火灾事故后,有必要对相关的法规进行重新修订。新修订的法规旨在更好的避免这种灾难,并当它确实发生时,能使被困人员尽快撤离危险地带而无需等待营救人员到达后再撤离。在隧道中一旦发生火灾,由于大量的烟以及很高的温度,会使被困人员迷失方向。所以在隧道内清晰无误的标示逃生路线是强制性的关键因素。所以,新的法规强调了必须在隧道内对求救电话以及逃生路线给予更清晰的标示。
With regard to the signaling devices used in tunnels, after several fire accidents have taken place, it is necessary to revise the relevant laws and regulations. The newly revised legislation aims to be better able to avert this catastrophe and, when it does, enable evacuees to evacuate dangerous areas as quickly as they can without having to wait for rescue workers to arrive before evacuating. In the event of a fire in a tunnel, people trapped will be disoriented due to the large amount of smoke and high temperatures. Therefore, clearly marking the escape route in the tunnel is a mandatory key factor. Therefore, the new regulations emphasize the need for clearer signage of distress calls and escape routes in tunnels.
