In case of fire emergency, follow these steps:

  1. Pull locking pin. To do so, it is necessary to break the tamper seal before. Rotate the locking pin and pull it.
  2. Hold the hose. Hold with your left hand the bottom part of the lever, grab the end of the hose with your right hand, near the hole. This way, it will be easier to direct the flow.

  3. Discharge the fire extinguisher. Calculate the correct distance, taking into account all different factors, like the direction of the wind and the fuel, then discharge the fire extinguisher pushing the upper part of the lever. The flow must be directed at the base of the fire, so to prevent the spreading of it due to the excessive pressure of the flow. Sweep side to side. When the fuel is liquid, the flow should not cause any tossing of the liquid outside its container.

  4. Do not operate from opposite positions. If two or more fire extinguishers are being used, the positions of the operators should never exceed a 90° angle.

  5. Put the fire extinguisher back to its place. Once you are sure that the fire is completely extinguished and you have excluded any possibility of reignition, leave the area and put the fire extinguisher back to its place.

The duration of the whole operation, on any fire, should be as short as possible, and it is important to use adequate equipment, including personal protection equipment, and to evaluate case by case the risk assessment of the fire and the surrounding environment.
Further advice: a) always have the wind behind your back, as the smoke does not allow to see perfectly and prevents to breath correctly; moreover, flames are often moved by the wind; b) evaluate well the most suitable orientation, so that the extinguishing agent will not be wasted; c) be very careful not to leave trace of flames, or the work done until that moment could be useless; d) extinguish first at the basis of the flames and then, if need be, on the ground; e) always go on with caution, possibly in a team; f) be extremely careful when operating on fires caused by under pressure machines or tanks, they could be lethal; g) if you are facing a small fire with a portable fire extinguisher, it is better to leave a small amount of extinguishing agent, in case of a reignition.
