Protection from Fire

3.4 Fire suppression

Fire suppression is dangerous and difficult even with good training and equipment. The following principles are especially important in remote areas:

  • Put "safety first!" If it's not safe, don't do it.

  • Concentrate on fire prevention and pre-suppression. The suppression techniques in this manual are appropriate in pressed grass and near fuelbreaks, not in tall grass.

  • Train a community fire brigade in fire suppression. Techniques like backfiring are not covered in this manual because they are not safe without more comprehensive training. Local government agencies may be able to provide such training; see Appendix A for fire protection manuals.

The fire brigade must determine ahead of time who will be the leader each time people gather to fight fires: the first capable person to arrive, the landowner, or the most experienced firefighter in the village. This leader must then make decisions about safety and how the group will fight the fire in a coordinated way.

Affordable equipment for fighting grass fires in isolated areas includes farm tools to make clean fire breaks, a gong or other alarm to call for help, and swatters to put out flames. Swatters can be made from truck mud flaps, or from burlap sacks that are soaked in water. Lookout towers can be built with local materials. Firefighters should wear cotton clothes (polyester may melt on the skin) and boots if possible. Firefighters should have containers for drinking water.

Before approaching a fire, judge how dangerous it is. Flames more than 2 m tall are not safe to fight directly. Even if the flames are low, it is not safe to fight a fire directly if it is likely to suddenly flare up. Try to predict its future behavior by considering:

  • the time of day. Fires usually become more active as the day gets hotter.

  • the wind. Fires spread with the wind, and become more active as wind increases.

  • nearby fuel. The flames will be twice as tall as the fuel they are burning. A fire may spread into tall fuel and suddenly get bigger.

  • steep slopes nearby. Fires tend to spread uphill quickly.

Always make sure that there is a safe "escape route" by which the firefighters can run to a safe area. Don't go into the middle of tall grass.

For small, controllable fires, attack the "head" (front) first, then work back down the "Hanks" (sides), then the rear. If it is not safe or not practical to attack the head, concentrate on protecting high value areas on the flanks or rear.

Watch out for the head or flanks spreading back toward the firefighters.
