|Crew briefings are crucial; each firefighter should be informed of the LCES (Lookout, Communications, Escape routes, Safety zones) system during this briefing.

The very nature of wildland fire suppression demands continuous size-up and hazard evaluation. Wildland firefighter and academic Paul Gleason developed a system known as LCES in 1991 as a direct response to firefighter fatalities during the Dude fire in Arizona in 1990. There is a good training clip online (Search YouTube for Dude Fire Fatality Case Study).
LCES stands for lookout(s), communication(s), escape routes and safety zone(s). Gleason determined that firefighters were overloaded with all they had to remember about personal safety. His solution was LCES, which is used by many firefighters worldwide. Some firefighters add the letter A to the acronym but there is confusion about whether the A stands for attitude, anchor points or accountability – which are all good safety points. For the sake of clarity we will stick to the original LCES. These original points encompass the 18 watchout situations and the 10 fire orders, of which most wildland firefighters are aware. In light of recent events, I encourage every fire department to review the LCES system.
Lookout(s): This individual must be trained to observe the wildland fire environment and to recognize and anticipate wildland fire behaviour changes. The lookout(s) must:
- Be experienced, competent and trusted;
- Be at a good vantage point(s);
- Have knowledge of crew locations;
- Have knowledge of escape and safety locations;
- Have knowledge of trigger and/or decision points.
- Confirm radio frequencies;
- Establish check-in times;
- Provide updates on any situation change;
- Sound alarms early, not late.
- Have more than one escape route;
- Avoid steep uphill routes;
- Scout the route for loose soil, rocks and vegetation;
- Time the route to consider fatigue and heat factors;
- Flag the route for day or night;
- Evaluate escape time versus the rate of fire spread;
- Park vehicles nearby for quick escape.
Safety zone(s): These are locations where firefighters may take refuge from the wildfire danger. The best safety zone is of no value if your escape route does not offer you timely access when needed. Remember:
- Scout a safety zone for size and hazards.
- Do not avoid the most obvious place; just taking a few steps into the recently burned-over ground may be all that is required, though you may have to burn out an area first.
- Look for rocky areas, water and meadows, but remember, rocks will hold the heat long after the fire has passed.
- Also look for man-made areas, such as clear cuts, roads and helicopter landing pads.
- Avoid upslope areas. Fire behaviour shows us that the rate of spread triples when it reaches a 25 per cent increase in slope. Trying to outpace a fire for any significant distance, especially uphill, is a losing battle. Study the 1949 Mann Gulch and the 1994 South Canyon fires, and you will soon discover that firefighters are not able to outrun a rapidly advancing flame front, even on a moderately steep slope.
- Avoid smoky areas – protect your airway at all costs.
- Avoid regions with heavy fuel loads. Be sure to select an area that won’t burn, or that has the least amount of combustible material.
|Wildland crews must have more than one escape route. Each route should lead to a safety zone and should be flagged in advance for day or night.
Along with LCES, we continually teach survival skills to our firefighters. The danger of being trapped or burned over and possibly
killed or seriously injured by a wildfire is a very real threat. Remember: victory loves preparation. Teach your firefighters survival skills and pray they never have to use them.
Teach them how to burn out fuels to create an area of safety or to enlarge an existing burned area. As Australian bushfire research pioneers Harry Luke and Alan McArthur noted in 1978, “Carrying a box of matches is part of survival planning.” We used to carry fusees (or flares), which are much more reliable and effective than matches, but they are hard to find now.
When caught in the open, survival may depend on taking advantage of every possible source of cover or protection from radiant and convective heat, for example, depressions in the ground, large rocks or logs. However, four firefighters died on a rockslide during the 2001 Thirty Mile fire in north-central Washington due in part to the accumulation of duff and rotting wood lodged in the rock crevices that ignited from airborne firebrands.
| Firefighters can take refuge in designated safety zones. These regions should be scouted in advance, and can include roads, meadows, and even ground that has recently been burned-over.
Last, but certainly not least, once you are in a safe zone, stay there until the threat that forced you into the safety zone is over. Firefighters die when they feel they have to do something. In the Thirty Mile fire, firefighters left the safe zone because they felt they should be doing something – and were forced back to its safety within 15 minutes. Unfortunately not everyone made it back safely. Those caught by the sudden fire behaviour change were forced to deploy their fire shelters. Tragically, four firefighters were killed.
The report looking into the 19 LODDs at the Yarnell Hill fire (available at www.azcentral.com/ic/pdf/yarnell-hill-fire-report.pdf) suggests quite a few similarities to the Thirty Mile fire.
The big question is why did the Granite Mountain Hot Shots leave the safe area in the already burned out region and hike through the thick, unburned fuels – some three metres high – down into the steep canyon as a powerful thunderstorm pushed flames directly at them.
I am baffled by that senseless decision, which in the end forced the Granite Mountain Hot Shots to deploy their fire shelters. Every crew leader knows that deployment of a fire shelter is a last-ditch effort in a life-and-death situation. It speaks to the fact that they should never have been in that area to begin with.
There are times when the phrase, “Don’t just stand there, do something,” should be “Don’t just do something, stand there.” When fighting a particularly risky fire, we have to trust that sometimes the best thing to do is nothing.
Until next time, train like lives depend on it, because they do. Let no firefighter’s ghost say that his training let him down!
