Heat stress management

    As a firefighter, you face a broad range of challenging environments, and working in turnout gear is tough on your body. You definitely need protection against extreme heat, but the vast majority of your calls don’t involve this kind of challenge. Nevertheless, heat is still a problem, and the heat you encounter during most calls can contribute to heat stress.

    SMALL INCREASES MATTER

    The human body can be extremely sensitive to small increases in core temperature. U.S. military studies have shown that once your temperature reaches 100°F, each increase of 0.1°F is physiologically significant, leading to an increased risk of heat exhaustion.

    YOUR CHOICE OF PROTECTIVE BARRIER MATTERS

    A recent human study evaluated the physiological impact of protective barriers currently available in turnout gear. Conducted by a third party, this study confirmed that wearing the GORE® PARALLON™ liner system delivered the highest breathability followed closely by GORE® CROSSTECH® black moisture barrier. Both of the GORE® protective barriers performed significantly better than the competition. In fact, 40 percent of the trial participants could not finish the test when wearing the competitive barrier because their heart rates exceeded their maximum rates, which were established as part of the safety criteria before the trial began.

     

    THL VERSUS RET TEST METHODS

    Testing the performance of the materials in your gear can provide valuable information for gear selection. The THL test has done a great deal of good for the firefighter, helping to improve how well gear can shed excess body heat; but it evaluates performance in a relatively mild environment, similar to a conditioned office space. And, it has been found that THL does not provide very useful information about how gear performs, particularly in warm or sunny conditions. The RET test can provide some of this valuable insight, which could be important to you in your gear selection.

    In addition, THL did not predict the differences seen in the human trials, whereas the RET testing did.

     

    YOUR JOB IS TOUGH, AND NO GEAR CAN CHANGE THAT. BUT TURNOUT GEAR WITH GORE® PROTECTIVE BARRIERS MANAGE HEAT STRESS SIGNIFICANTLY BETTER THAN THE COMPETITIVE BARRIER. YOU WORK IN ALL TYPES OF CONDITIONS...SO SHOULD YOUR GEAR!

    stay on your feet with Leather boots

    Study shows that leather boots keep you on your feet!

    Your boots play an important role in your protection and safety, and for years, there has been thought that leather boots provided better footing. Now, thanks to a joint research study by Auburn University and the University of Mississippi there is support for this thinking.

    In the study, professional firefighters participated in fire simulation activities wearing rubber boots and then leather boots, separated by a rest period. The results of the study indicated that the firefighters were four times more likely to have a hazardous slip when wearing rubber boots than when wearing leather boots.

    The Economics of Leather Boots

    In cases where departments may prefer leather boots for improved comfort and agility, budget constraints may result in settling for rubber boots with an initial cost between $100 and $200 less than leather. However, the cost of potential injury may not be considered in these decisions.

    Based on a recent NFPA report of line-of-duty injuries, more than 14,700 firefighters (out of 1.1 million) were injured because of falls, slips, or jumps in 2011, and the National Safety Council has determined that the average cost for a slip/fall injury was $41,393.

    Bringing these figures closer to home...in a department with 1,000 firefighters*, the above reports' data would suggest that approximately 12 members would have sustained a slip/fall injury in 2011, for a total cost of almost $500,000. Additionally, based on the data from the universities' research study, wearing leather boots instead of rubber can potentially lower a fire department's rate of slip/fall injury by 4 times – translating to saving your department $375,000, or $375 per firefighter.

    Data suggests that spending $100 to $200 for premium leather boots can increase traction, reduce the number of injuries, and potentially save $375 in medical costs – not to mention the lost time incurred and hardship for fellow firefighters!
