一旦发生火灾,最重要的是保持镇静,不要盲目行动。火灾现场能见度非常低,在这种情况下,应尽量利用建筑物内设施逃生,以争取相对较多的逃生机会。 In the event of a fire, the most important thing is to remain calm and do not act blindly. Visibility at the scene of the fire is very low, in this case, should make full use of facilities within the building to escape in order to fight for a relatively large number of escape opportunities.
