handline

1.The four personnel on the handline would have been better used with two on the handline and two doing rescue and relocating the injured away from the dangers.

消防人员手持喷头的情况，可以更好地修正为两手持喷头，另两从险境中将伤员救出。

2.Why did the 4-5 fire fighters go to the bus (tail section) without a handline?

为什麽4-5名消防人员走向大巴士（飞机尾部）而没有携带手持水管？
