- A large version of the New Generation fire
shelter is available.
- The large version is recommended for
firefighters who are taller than 6 feet 1 inch
or whose girth is larger than 53 inches.
- The large version weighs just 0.6 pounds
more than the regular fire shelter and can
be carried in the same hard-plastic liner
- Firefighters who are shorter than 5 feet 7 inches may have difficulty deploying and holding down the large fire shelter.
A large version of the New Generation fire shelter is available for big firefighters. The New Generation fire shelter has been available to firefighters since 2003, but it was designed in just one size based on data from the military and on early trials of the shelter. Feedback from the field prompted development of a large shelter to provide better protection for larger individuals by:
- Reducing body contact with the hot shelter material
- Providing more insulating air space between the
shelter material and the occupant
- Preventing the shelter from being damaged when a larger person stretches out inside the shelter and pushes hard against the shelter material
The large shelter is longer, wider, and taller than the regular shelter (figure 1) and weighs about 0.6 pounds more. Table 1 shows the dimensions of both shelters. The large shelter fits easily into the hard plastic liner and case used for the regular shelter. The large shelter is easily identified by the word "LARGE" stenciled on the quick-deployment strap that is stitched onto the plastic bag holding the shelter. The large shelter's deployment strap is orange, rather than yellow (figure 2), the color of the strap on the regular shelter. This strap is visible whether the shelter is inside or outside its case.
|Large fire shelter (inches)||Regular fire shelter (inches)|
|Packed size||9 x 5.5 x 4||8.5 x 5.5 x 4|
The large fire shelter was designed for firefighters whose height or girth prevents them from fitting easily inside the regular shelter (figure 3). Any firefighter taller than 6 feet 1 inch should carry the large shelter. Any firefighter whose girth is larger than 53 inches at any point also should carry the large shelter. Girth around the shoulder area should be measured with your arms at your side.
Figure 3—This firefighter, who is 6 feet 2 inches
tall and weighs 235 pounds, will find the large fire
shelter roomier than the regular shelter. The photo
has been digitally altered to show the firefighter
as though the shelter was transparent.
Anyone who carries the large fire shelter should experiment with a large practice fire shelter to become familiar with the shelter's fit. If your height or girth would not require you to use a large shelter, you may request one if you try a regular shelter and feel it is too small for you. You should be able to:
- Lie face down inside the shelter while wearing a
hardhat and boots without pushing against the ends
of the shelter.
- Lie in the shelter with your arms through the holddown
- Fold your elbows next to your chest and protect the sides of your face with your hands with only minimal contact with the sides of the shelter.
In trials using fans to simulate wind, firefighters shorter than 5 feet 7 inches had difficulty deploying and holding down the large fire shelter. Firefighters shorter than 5 feet 7 inches should carry the regular shelter. Firefighters who are shorter than 5 feet 7 inches, but whose girth is larger than 53 inches, should practice with the large practice shelter in a strong wind before deciding whether to carry a large shelter on the fireline.
In an emergency, a small firefighter could use a large shelter if a regular shelter was not available. Small firefighters should:
- Hold the large fire shelter down by placing their
feet far into one end of the shelter to prevent the
foot end from catching in the wind and exposing
their body to hot gases.
- Place their arms through the holddown straps up to the elbows.
- Gather the floor material with their hands to help control the shelter and provide as good a seal as possible with the ground.
All fire shelter training applies to the new large fire shelter just as it does the regular shelter. Deployment procedures have not changed. However, deployment training is required with the large practice shelter before a firefighter should carry a large fire shelter to the fireline. The minimum training before either fire shelter is carried on the fireline includes:
- Reading the training pamphlet, The New Generation Fire Shelter
- Viewing the training video or DVD, The New Generation Fire Shelter
- Practicing deployments using a practice fire shelter of the appropriate size
The video and pamphlet include information on how the shelter works, how it is deployed, how to select a deployment site, what a firefighter might experience during an entrapment, how to train to use the shelter, and how to care for and inspect the shelter. A large practice fire shelter will be available during the summer of 2005. The new large practice shelter is orange. The regular-size practice shelter is green. Both practice shelters fit into the same case. The reusable practice shelter bag has been resized so it can accommodate both sizes of fire shelters.Ordering Information
