NWCG’s position on firefighter-cancer study

Before we published the article on April 23 about the study that NIOSH is conducting on a possible link between structural firefighters and the occurrence of cancer, as part of our research we emailed Michelle Ryerson, the chair of the National Wildfire Coordinating Group’s Risk Management committee, formerly called the Safety and Health Working Team. We asked if the NWCG was aware of any similar studies that involved wildland firefighters. We also explained to her that we had talked with Travis Kubale, the NIOSH study’s primary project officer, who at the end of the conversation became interested in perhaps doing a cancer study on wildland firefighters. We passed along Mr. Kubale’s contact information to Ms. Ryerson, as well as others in the NWCG.

Today we received a response from Ms. Ryerson, which she called “an update from the NWCG Risk Management Committee perspective”:

  • NWCG was never approached by NIOSH to be included in this study.
  • The NWCG is coordinating with US Fire Administration on potential of including wildland fire to the NIOSH study.
  • NWCG has an active Smoke Exposure Task Group (SETG) under the auspices of RMC who’s focus is smoke hazard identification and mitigation for wildland firefighters and support personnel in fire camp environments (SETG website should be up and working by end of May).
  • The SETG began smoke exposure monitoring in 2009 and will continue monitoring in 2010 so that we can better understand the levels of smoke exposure both in fire camp and fireline operations.
  • The SETG is also preparing a long-term project proposal abstract to seek study sponsorship from universities, NIOSH, and other scientifical organizations.
  • Also worth mentioning is the fact that the DOI, FS, and many state agencies have instituted wildland firefighter medical standards programs that help track firefighter health issues throughout their arduous duty fire career.

We replied to Ms. Ryerson and the others that she had cc’d with her response:

I can imagine that employers of wildland firefighters may not be enthusiastic about opening a can of worms that may link cancer with exposure to smoke on wildland fires, but the Right Thing To Do is to look at this issue and either prove or disprove a link. I hope the NWCG will not only continue to collect data about the fire environment, but will also pursue a possible cancer link with just as much enthusiasm.

After devastating fire, Rome, Wisc passes brush clearance ordinance

Five years ago the Cottonville fire destroyed 30 homes and burned 3,410 acres near Rome, Wisconsin (map). In December the Town Board inacted a new ordinance that requires clearance of vegetation on private property.

  • Anyone who owns property smaller than 2 acres must keep it free of dead trees and brush, regardless of whether there is a structure on the land.
  • Anyone with 2 acres or more must keep dead trees and brush cleared away from within 100 feet of structures.

Dalmation90 sent us a link to this photo that is from an article on the Wildfire Lessons Learned web site. It was taken in Minnesota by Peter Willis, State of Minnesota.

Wildfire Today travel mugThe photo is missing one thing. A caption. In order to fix this oversight, we are have having a Caption the Photo contest. The person who submits the best caption will receive a Wildfire Today travel mug from our little Wildfire Today store.

The rules for this contest are relatively simple. To enter, put your Caption in a Comment or Response below this post. There is a limit of three entries for each person. We reserve the right to change these rules at any time. The winning caption will be selected by us, using completely arbitrary and capricious criteria.

If you win, you will send us a photo of the mug taken at your place of work which we will publish here.

The contest will end Monday night at midnight, 11:59 MT, May 10.

Firefighting in Minnesota

Fighting a wildfre in Minnesota is different in some ways. The Land of a Thousand Lakes has a lot of aircraft runways….as long as your aircraft is equipped with floats like the Air Tractor in the photo above. Even the U.S. Forest Service owns at least a couple of aircraft on floats, vintage aircraft at that, DeHavilland Beavers which were last manufactured in 1967.

Minnesota Public Radio has an interesting article about the current fire conditions in their state. As you can see in the fire potential maps we posted yesterday, the northern part of the state has “above normal” wildland fire potential. It is so dry that the land management agencies have assembled a large contingent of firefighting aircraft, including two large air tankers, three CL-215’s, two Air Tractors, and 15 helicopters.

The article has a great slide show of 11 photos of their firefighters and their equipment. Check it out.

Wildland fire outlook, May-August

Today the National Interagency Fire Center issued their Wildland Fire Potential Outlook for May through August. Here is the narrative from the site:

  • Drought: Drought conditions continue to persist over northeast California and northwest Nevada, western Wyoming, western Montana and much of Idaho.
  • Snowpack: Snowpack in the Southwest has been well above average, while in western Wyoming through the northern Rockies the snowpack has been well below average.
  • Grassland Fuels: Abundant fine fuels across southern Arizona are expected to lead to a 4-6 week active grassland fire season. Fine fuels are not expected to be of concern in the Great Basin. There is an increased large fire risk over the California desert areas in June due to fine fuels decreasing to normal by July.
  • Fire Season Onset: In areas with above average snowpack, fire season onset will be delayed due to a later snowpack melt.
  • Southwest Monsoon: Early indications suggest monsoon onset will occur around the typical start date or later with associated precipitation amounts near normal for the season.

Unusual smoke column behavior

Talking Points Memo has a slide show of stunning pictures of the last hours of the Deepwater Horizon oil drilling rig as it burned and sank into the Gulf of Mexico.  While all nine of the pictures are fascinating, the one above captured my interest. It appears that something unusual is occurring with the smoke column, in that a narrow rotating column seems to be descending from the main smoke column, and the smoke from this object is accumulating above the ocean surface quite a distance from the fire.

Could this be a partial collapsing of the convection column, a phenomenon that occasionally occurs in the column over a wildland fire? You Fire Behavior Analysts, what do you think?
