Alabaugh Fire to be Part of 2008 Refresher Training

Every spring the national wildland fire agencies produce and distribute a standardized training package designed to meet the requirements for 8 hours of refresher training for wildland firefighters. The training usually includes a description of unique incidents or near-misses that occurred in the previous season. This year the training will feature an entrapment of two firefighters on the Alabaugh fire in July of last year. On the fire, which started 5 miles southeast of Hot Springs, South Dakota, the firefighters escaped serious injuries by sharing one fire shelter.

In addition to the photo with this post, the photo in the header at the top of this page is of the Alabaugh fire. In December the producers of the refresher training shot some video interviews at the houses that you can see in the header photo.

Wildfire statistics



We all know that wildland fires are larger than they used to be. Almost every summer recently there are fires that exceed 100,000 acres. Before 1990 this was not common.

I analyzed some fire occurrence statistics obtained from the National Interagency Fire Center and the National Incident Information Center. The numbers for 2007 are through November 4, 2007. Usually when fire occurrence statistics are displayed you will see total acres and the number of fires by year. But when I computed the average size of fires for each decade, the 1970s through 2007, a trend is painfully obvious. During those four decades the average size of fires increased by 400%, while the average number of fires each year decreased by 44%. (Click on the graphs to make them larger.)

But why are fires larger? Some of the factors that could cause such an increase in the average size are:

  • Fire suppression for the last 100 years is catching up with us. Preventing naturally occurring fires to routinely reduce the fuel loads increases the amount of fuel, and the continuity of it, available when a fire starts. Fires burn more intensely and with more resistance to control.
  • Climate change. There is no doubt that temperatures in the last few decades have been higher that they were before this period. We can debate how this may have affected wildland fires. Many areas have had extended droughts, causing die back of brush and shrubs. Trees are stressed, making them more susceptible to insects and other pests. Do these higher temperatures have a direct effect on fire behavior on an hour by hour basis?

U. S. Wildland Fire Fatality Report–2007

The Safety and Health Working Team, part of the National Wildfire Coordinating Group, on January 15 released a “Safety Gram” listing the wildland fire related fatalities in 2007.

“Nine fatalities occurred in 2007 when employees were performing wildland fire management activities. This is a substantial decrease from the 24 fatalities that were reported in 2006. Also noteworthy is the absence of any entrapment or burnover related fatalities.

  • Aviation – 1: Fatality occurred when helicopter was performing logistical support.
  • Driving – 3: Fatalities occurred when firefighters were returning from a prescribed fire (1) and training (2).
  • Hazard Tree/Snag – 1: Fatality occurred when a tree fell on a firefighter during chain saw training.
  • Heart Attacks – 2: Fatalities occurred following the Work Capacity Test (pack test) and firefighting.
  • Other – 2: Fatalities occurred when a dozer rolled over while constructing fire line (1) and by electrocution (1).”

 

Black Lining With a Machine

The U.S. Fish and Wildlife Service in South Dakota has been experimenting with a tractor-towed machine that creates black lines which can be put in prior to a prescribed fire. Black lines, a relatively narrow strip of burned vegetation along the perimeter of a planned prescribed fire project, can make the ignition and holding of the main burn go much more quickly and also reduce the chance of a slop-over.

The equipment is made by Firebreak Equipment, a firm in South Africa. Their web site does not play well with Firefox–it’s better with Internet Explorer. More photos are on their web album.

The device uses propane burners in a metal enclosure to burn the ground fuel, while water nozzles on the sides create a wet line to keep the fire from spreading. This toy tool looks like it would be fun to play with.
