PASS System

Since acronyms are easier to recall, most people refer to the correct operation of an extinguisher as the PASS System. Here is a breakdown of the stages:

P – Pull the pin – The first thing you need to do is pull the pin on the extinguisher you have chosen. This will then allow you to activate the extinguisher, releasing the locking mechanism.

A – Aim – Now the pin has released the locking mechanism, you should aim the nozzle of the extinguisher at the bottom of the fire – not at the flames. By targeting the base you are tackling the fuel source of the fire and putting the extinguishing effect in the right place.

S – Squeeze the level – You’ve got your aim and the extinguisher is unlocked, now you simply need to squeeze the lever to begin releasing the extinguishing agent. There is a limited amount of the agent inside every extinguisher, so use it wisely and squeeze only to get a controlled amount.

S – Sweep – You should be a good distance away from the fire itself when using the extinguisher. Keep aiming at the base of the fire and sweep back and forth to cover as much of the base of the fire as possible. If the fire begins to recede, adjust your position and continue to spray as long as the extinguisher allows.

It’s possible that once you have put the fire out, it finds a way to reignite. To avoid this, we suggest staying close by for a short period in order to monitor the remains of the fire, ready to tackle the flames should they try to take hold again.

It should go without saying that, should the fire roar back to life in an aggressive manner, you should leave immediately and let the emergency services tackle the fire. Never take on extinguishing a fire unless you are certain you can handle it.

由于首字母缩略词更易于回忆，因此大多数人将灭火器的正确操作称为PASS系统。以下是各阶段的细分：

P  - 拉销 - 您需要做的第一件事就是将销钉拉到您选择的灭火器上。然后，这将允许您激活灭火器，释放锁定机制。

A  - 目的 - 现在销钉释放了锁定机构，你应该将灭火器的喷嘴对准火焰的底部 - 而不是火焰。通过瞄准基地，您正在解决火灾的燃料来源并将灭火效果放在正确的位置。

S  - 挤压水平 - 你已经达到了目标并且灭火器已经解锁，现在你只需要挤压杠杆即可开始释放灭火剂。每个灭火器内部的药剂数量有限，因此明智地使用它并挤压只能控制量。

S  - 扫描 - 使用灭火器时，您应远离火源。保持瞄准火的底部并来回扫过尽可能多的火焰底部。如果火势开始消退，请调整您的位置，并在灭火器允许的情况下继续喷射。

一旦你把火扑灭，它就有可能找到重新点燃的方法。为了避免这种情况，我们建议在附近停留一小段时间，以便监控火灾的残骸，如果他们试图再次抓住，他们准备应对火焰。

不言而喻，如果火灾以激进的方式咆哮，你应立即离开并让紧急服务部门解决火灾问题。除非您确定可以处理火灾，否则永远不要灭火。
