NWCG Standards for M-2002 Fire Shelters: Selecting Your Deployment Site

The characteristics of an effective deployment site have not changed. Your goal in selecting a deployment site is to keep the fire shelter away from heat, especially flames. Practice evaluating deployment sites so that you can recognize them quickly under stress. Identify effective sites whenever you are on the fireline so you know where they are before you need one.

1. Keep away from narrow draws, chutes, and chimneys. They tend to funnel smoke, flames, and hot gases that can damage your shelter.

2. Avoid saddles on ridgetops. They also funnel smoke and heat.

3. Flat areas on slopes, such as benches, or road cuts, offer some protection from radiant and convective heat. These level areas can keep you below the path of flame and convective heat. Do not deploy in the middle of a road if vehicles may be passing. A drainage ditch on the uphill side of a road cut can be an effective deployment site unless it contains fuels that could ignite and burn the shelter. Four firefighters deployed their fire shelters on this road during a burnover. All four survived with only minor burns.

4. Stay out of draws, even when deploying on a road.

5. Try to pick natural firebreaks such as wet meadows, wide streambeds, swampy areas, and rockslides.

6. Do not deploy in or next to tall or thick grass, small trees, trees with low branches, brush, piles of slash, or firefighting equipment such as packs, parachutes, tools, or chain saws. Firefighters have been burned because they deployed too close to such fuels. Large rockslides can be effective deployment sites, but you must stay away from brush and trees, and from fuels scattered in the rocks. Even though it can be difficult to hold the edges of the shelter down, large, jumbled rocks, rockslides sometimes offer the largest area free of fuels and may be the best option for deployment.

7. Ground fuels, such as grass, or tree litter, can ignite rapidly. Clear the deployment site to mineral soil if time allows. If time is critical, pick a site with the sparsest fuels.

8. Deploy fire shelters well away from thick vegetation such as the shrubby understory and trees.

9. Boulders, large rocks, buildings, vehicles, and equipment can provide buffers from the heat of the fire. Keep in mind that when vehicles, equipment, and buildings catch fire, they burn hot, and for a much longer duration than the vegetation around them. This can lead to shelters being exposed to heat for a prolonged period, well after the flame front has passed. This may keep firefighters in their shelters longer, exposed to prolonged levels of dangerous heat.

10. Avoid areas where rocks or logs can roll on you or snags can fall on you.

11. The lee side of a ridgetop can be an effective deployment site because the flames and hot gases tend to rise above the ridge. Fire intensity usually drops when fire reaches a ridge. But be alert for the possibility that firebrands might ignite fires below you on the lee side of the ridge.

12. Burned-out areas can be effective deployment sites if there is no fuel left to reburn. Be aware of residual heat and hotspots on the ground. Scrape the ground if possible to clear away any heat and burning materials. Burn injuries have occurred from firefighters deploying in the black that was still hot.

13. Wide areas that have been cleared of fuel, such as dozer lines or roads, can be good deployment sites, depending on the size of the area that has been cleared and the behavior of the fire.

14. Bodies of water can be adequate deployment zones, however you should be aware of several hazards if you find yourself having to use a body of water. Deployments can last from several minutes to an hour or more. If the water is over your head in depth, you may be at higher risk of drowning especially once your boots and clothing become waterlogged. Since water removes heat from the body much faster than air, you may be at risk of hypothermia from deployments in bodies of water. If there is a current to the water your fire shelter may be hard to hold on to or you may become entangled in your shelter and drown. The fire shelter’s ends can fill with water and become very heavy. For further information read this tech tip on deploying in bodies of water.

RMC Safety Bulletin 26-001: Rhabdomyolysis in Wildland Firefighters

Date:  May 28, 2026
Questions? 
Please contact: Risk Management Committee

The Risk Management Committee (RMC) has issued Safety Bulletin 26-001: Rhabdomyolysis in Wildland Firefighters. Research from 2016 to 2025 shows that 88 cases of rhabdomyolysis (rhabdo) were reported. Analysis of reports from eSafety, the Safety Management Information System (SMIS), and the Wildland Fire Lessons Learned Center (LLC) indicates that rhabdo is common during this time of year due to Work Capacity Tests and contributing factors such as weather, hydration, nutrition, and medication or supplement use.

RMC issued this safety bulletin to raise awareness in the Wildland Fire Community, and to provide research findings and educational resources that support reducing future cases of rhabdo.
