Wildland Fire Fighting Safety and HealthPosted on by
Wildland fires continue to increase in the Western United States as hot, dry and windy conditions persist, resulting in an extended fire season and factors conducive to fires. Currently, drought conditions are prevalent in the West due to low snow-pack levels, below average rainfall, record setting temperatures and high winds, resulting in a greater than average number of fires this year. Since January 2012, over 32,000 fires have burned almost 3.3 million acres in the US. [NIFC, 2012a]. (For current data see the Fighting Wildfires Topic Page). Additionally, in the last 50 years, there has been a general increase in the occurrence and severity of forest wildfires in the US, as over 5 million wildfires have burned over 206 million acres [NIFC, 2012b].
When wildland fires occur in the Wildland Urban Interface (WUI), the area where houses meet undeveloped land, they can easily become catastrophic because a large number of people, homes and structures are at-risk. When a fire ignites in these areas, a quick and aggressive response from wildland fire agencies and wildland fire fighters is required.
Wildland fire fighting can be a dangerous occupation. Over the past 10 years, over 200 fire fighters have died while participating in wildland fire suppression activities [USFA, 2001-2010]. These fatalities have occurred among federal, state and local fire fighters as well as private and military personnel. Although a variety of agencies track wildland fire fighter fatality data a national system for collecting data on non-fatal injuries and illnesses among wildland fire fighters does not exist. Research studies that evaluated injuries at specific fires show that the types of injuries that occurred while fighting fires and working in fire camps include falls, strains, burns, being struck-by-objects and vehicle-related incidents [Kiefer, 2004; Britton, 2010].
In 2010, there were approximately 34,000 federal workers employed in wildland fire suppression activities [Ryerson, 2011] and an unknown number of volunteer wildland fire fighters. Ensuring fire fighter safety during the challenging conditions encountered when responding to a wildland fire (rapid response, poor visibility, uncharacterized hazards, unfamiliarity with the environment, etc.) requires knowledge of hazards and commitment to safety by Incident Commanders, Fire Management and Safety Officers. Safety programs should be established that include employee training on safe work practices, recognition and reporting of hazards, appropriate personal protective equipment and frequent safety program evaluation.
Hazards that wildland fire fighters may encounter include:
Fire fighters working in hot weather may experience heat stress (feeling hot, tired or fatigue, weakness, vertigo, headache, or nausea). Heat stress can progress into heat strain (physiologic changes such as e.g., increased core body temperature and heart rate) and, without appropriate intervention, can progress into heat-related illnesses (heat rash, cramps, exhaustion or heat stroke). Risk factors for heat-related illness include:
- Strenuous work performed while fighting fires
- High environmental heat load (temperature, humidity, air movement and radiant heat)
- Personal risk factors (age, physical fitness, and existing medical conditions)
- Dehydration from insufficient fluid intake
- Insufficient acclimatization to heat
- Sleep deprivation and fatigue
- Burdensome personal protective equipment
How to Prevent and Reduce Heat Stress
Recommendations for Incident Commanders and Fire Managers
- Provide training to fire fighters on recognizing, understanding and preventing heat stress
- Reduce the physical demands of workers
- Use relief fire fighters and/or assign extra fire fighters for physically demanding jobs
- Schedule hot jobs for the cooler part of the day whenever possible
- Acclimatize fire fighters by exposing them for progressively longer periods to hot work environments
- Provide cool water or liquids to fire fighters
- Provide rest periods in cooler areas with water breaks
- Monitor fire fighters for signs of heat stress
Recommendations for Wildland Fire Fighters
When possible, fire fighters should avoid exposure to extreme heat, sun exposure and high humidity. When these exposures cannot be avoided, fire fighters should take the following steps to prevent heat stress:
- Take more breaks in extreme heat and humidity
- Take breaks in the shade or a cool area when possible
- Drink water frequently. Drink enough water that you never become thirsty (about 1 cup every 15-20 minutes)
- Avoid alcohol and drinks with large amounts of caffeine or sugar
- Be aware that protective clothing or personal protective equipment may increase the risk of heat stress, particularly turnout-gear
- Monitor your physical condition and that of your fellow fire fighters and notify emergency personnel if heat stress symptoms occur, stop working, notify emergency personnel immediately, move to a cooler area and begin cooling activities to reduce the body’s temperature
Fire fighters can also experience physical and mental fatigue during a wildland fire due to strenuous work activity, high altitudes, long and irregular work shifts, lack of sleep and/or quality sleep, improper nutrition and unpredictable and stressful events. Fatigue and stress can increase the risk of injury, accidents and poor health. Studies show that working 12 hours or more per day is associated with a 37% increased risk of injury [Dembe, 2005].
How to Prevent and Reduce Fatigue:
- Allow enough time to sleep after shift work and on days off
- Avoid heavy foods before sleeping
- Reduce intake of caffeine and other stimulants several hours before sleeping
- Ensure fluid and nutritional needs are met and that work/rest cycles are implemented to prevent unnecessary fatigue among both fire fighters and fire managers
Wildland fire fighters are also exposed to a variety of hazards that may put them at risk of both fatal and non-fatal injuries while on the job. Hazards wildland fire fighters may encounter include:
- Slips, trips and falls
- Burns, including sun-burns
- Scrapes and cuts from tools and equipment, such as chain-saws
- Struck-by partially burned trees, other objects in the forest or vehicles (e.g. fire equipment, ATVs, etc.)
- Contact with plant irritants and sensitizers (e.g., poison ivy, thorns)
- Snake/animal bites
- Injuries sustained in crashes of vehicles/airplanes/helicopters
- Electrocution from downed power lines and lightning storms
- Unstable building structures
Recommendations to Reduce Injuries:
- Ensure fire fighters are informed of potential hazards, how to avoid them and the need to report all occupational injuries/illnesses and unsafe conditions
- Establish and implement LCES (lookouts, communication, escape routes and safety zones) before fire fighting begins
- Ensure fire fighters receive training on safe response to emergencies and to always be aware of the potential to be caught in a burnover
- Establish and enforce standard operating procedures for operating motor vehicles and wearing seat belts (restraints)
- Ensure all wildland fire fighters wear wildland personal protective equipment that is compliant with the National Fire Protection Association (NFPA) Standard on Protective Clothing and Equipment for Wildland Fire Fighting (1977)
Respiratory Hazards from Smoke, Ash and Debris
Smoke and dust from a wildland fire can be composed of a variety of inhalation health hazards, including gases, such as carbon monoxide, sulfur dioxide and formaldehyde, and particulates, including ash and silica [Austin, 2008] [Reinhardt and Ottmar, 2004] [Harrison, et al 1995]. Structural fires that occur during a wildland fire may generate additional hazardous contaminants from the many materials present in homes and buildings. For example, car batteries or mercury light bulbs present in homes and buildings, especially older buildings have a greater potential to contain asbestos and lead. Incident Commanders, Fire Managers and fire fighters should always be aware of the risk for smoke inhalation, the potential hazards associated with ash and the precautions that should be taken to prevent and reduce exposure.
Recommendations to Limit Exposure to Smoke, Ash and Debris:
- Utilize fire operations procedures that reduce smoke exposure, such as:
- rotating crews through areas of heavy smoke
- avoiding downwind fire fighting, whenever possible
- minimizing mop-up whenever possible
- using equipment rather than people in holding areas, when possible
- Locate camps and Incident Command Posts in areas that are upwind of the fire and not prone to inversions
- Use protective clothing and equipment to avoid skin contact with ash
- Thoroughly wet areas to reduce ash and dust generation
- Ensure fire fighters are trained on the risks of smoke inhalation and exposure to ash and how to reduce their risk of exposure
Fire fighters are also at risk for heart attacks, strokes and other cardiac related events while fighting wildland fires.
Recommendations to Reduce the Risk of a Cardiac-related Event:
- Ensure fire fighters maintain good physical fitness and aerobic and muscular endurance training
- Implement a pre-employment medical screening and medical examination program, including exercise stress tests following standard medical guidelines for all fire fighters
- Implement a comprehensive wellness and fitness program for fire fighters consistent with NFPA 1583, Standard on Health-Related Fitness Programs For Fire Fighters (see http://www.nfpa.org/aboutthecodes/AboutTheCodes.asp?DocNum=1583)
- Fire fighters should participate in pre-placement and annual medical examinations and physical performance (physical ability) evaluations before engaging in fire response activities
Wildland fire fighting can be a dangerous occupation. These men and women place themselves in harms way to protect the lives and property of those living in the affected areas. Following the recommendations above and using the additional resources below can help protect fire fighters from the hazards associated with wildland fire fighting. We would like to hear from those involved in wildland fire fighting. Have you experienced any of the issues we discuss in this blog? Are there any unique issues with the current fires?

Thanks for highlighting the hazards faced by these amazing public workers and the ways of making thier jobs safer!
This is an exhaustive list by the CDC. Thank you for that. Particularly fire fighters finding themselves in a stressful situation might find this helpful – however perhaps a little checklist for that might be even more helpful. (something to remember, maybe with e mnemonic device)
We have discussed additional ways to communicate this information. We welcome suggestions from fire fighters and managers as to what would be useful – fact sheet or poster for posting in break areas, tweets, pocket card, etc.
Great overview of the hazards that can be avoided. The public workers definiltey offer alot of value to us.
It all starts with the basics for wildland firefighters. The instructor can not stress enough the need to hydrate, especially BEFORE an incident. It continues with the safety officers that preach hydration daily at briefings. However, much like any other safety issue, the firefighter him/herself, much take the personal responsibility to hydrate, hydrate, hydrate!!!
I’ve often wondered why local fire departments don’t get more involved in heat stress awareness, both to the general public as well as to local businesses. It seems to me that more than anyone else, firefighters are all too aware of the dangers that heat stress imposes upon the human body.
Really big list! I think you have listed out almost all the points that needs to be taken care of. Appreciable effort!
You have share very big list of recommendation about how to Prevent and Reduce Heat Stress.I really like your recommendations and thanks for it.
Being in Singapore where the weather is burning hot year round, heat stress management is no joke!
Thanks for sharing this list of recommendation on how to prevent fire accidents and heat injuries. It reminds the general public how much those brave firefighters risk for the public good. They put their lives at risks so that others can live safer. This is one of the jobs that deserves the most respect from the community.
Thank you for such a throrough list. Having witnessed the wildfires in the Canary Islands recently, many of the recommendations you suggested would have been very welcome.
Firefighters work closely with the local community to increase their level of fire safety awareness in order to help prevent fires and accidents occurring in the first place. They promote fire safety and enforce fire safety standards in public and commercial premises by acting and advising on all matters relating to the protection of life and property from fire and other risks.For more information please visit [http://www.safedesign.com/]
Your information is very helpful. I think we could print some booklets and deliver them to people who live in forest or near forest. Thus, few people will be hurt by wildland fire.
Thank you for sharing this.
Firefighters used to face stress during the fire operation. Heat stress shows so many impacts on the human body. understand the heat stress. Drink lots of water, hydrate the body is the good option in reducing the heat stress.
10/10 for this page
You don’t need superpowers to become a real-life superhero. All it takes is unselfishness, courage, and determination. Kudos to our firefighters and soldiers.
Being prepared for a wildfire is incredibly important and something that many people fail to do. Great post!
This information was helpful – thank you!
thumbs up to the fire fighters!
their tasks are no joke.
I love this post too, thanks.
Its nice to have a blog from the governement about our niche . Its strange that we were not involving this in school syllabuses .Municipal Training Corporations trains people to become fire fighters of stealth and they are well experienced and educated and quick to make decisions . We’re proud to do it as this are situations where our experience helps to save lives and properties.
Drinking 1 cup of water every 15-20 minutes is a fantastic idea, however constant trips to the water fountain or carrying water bottles can be a pain. A great solution is getting a proper hydration system.
Always essential learning different kinds of fire safety and drills. It can be applied in homes and other places like buildings.
Great blog post. Is there still no formal data tracking system for non-fatality related injuries? Anything on musculoskeletal-related injuries?
I am a former hotshot crewmember and currently a physical therapy student. Injuries are something we need to start tracking and prevention is an area I am interested in getting involved in.
Learning on updated safety drills is a must. It’s a progressing thing that we should to know.
I am a former Helicopter crew member, Helicopter Manager, Red Team Member, Type I and Type II wild land fire fighter with over 36 years experience. Any health studies related to fire fighters working on Nuclear Plants, Nuclear Burial Sites and mines would help. I worked as an on call fire fighter and emergency crew member at the Savannah River Site and on fires with uranium mines in Washington State. I am currently working at a TVA Nuclear Plant exposed to wild land fire smoke daily. Thanks for your study.
here are some quick thoughts- because at this point if you are ordered to receive higher medical care and you have dehydration symptoms (i.e. vomiting, abdominal pain, etc.), OWCP classifies it as an “illness” not “traumatic injury”- and CA-16 (authorization for initial treatment) is not used on CA-2 (occupational illness). This typically leaves the firefighter responsible for the air or ground ambulance and other medical bills :
medical documentation regarding OWCP should be added to IRPG and more of an emphasis regarding documentation and financial responsibilities for using non agency medevac procedures. you order it, you pay for it. the most highly medically trained personnel should be delegated authority over medicals with NO INTERRUPTION from those higher in the typical operations ICS. Policy in Washington should stop making blanket policy for federal employees based on their “home unit/district” and formulate separate policy recognizing the unique, and often remote, location (in addition to environmental factors) influencing wildland forest service personell on their HUGE “home unit” or district. Every firefighter I have ever met has been impacted or knows AT LEAST one other wildland firefighter affected by the challenges of OWCP and medical situations arising while on an incident. AND WHEN IT HAPPENS, THIS INJURED OR ILL FIREFIGHTER IS NOT THE AUTHORITY FOR EVAC OR NEXT LEVEL OF CARE. crew boss/supervisor should not be the one responsible for ensuring paperwork is complete regarding authorizations- THEY ARE ON AN INCIDENT RESPONSIBLE FOR SUBORDINATES…. FOCUS ON THIS PLEEEEASE!! hospital liason is not a primary role on forests always, its often supplemental/additional duty. If you want to put firefighters FIRST, develop controls for the OWCP process and fight to change the prior authorization (CA-16) to be AUTOMATIC for WILDLAND FIRE PERSONNEL REGARDLESS OF CA-1 or CA-2 being recommended by ASC HRM.
why is it up to someone in Albuquerque?>?>?> FECA is a benefit that sounds great, but realistically should be personalized for wildland firefighters who RISK their LIVES every shift.
Your blog is very informative. Thanks for sharing this list of recommendation on how to prevent fire accidents.
I got to know a lot through this blog so that I can grow in my career. I find the information you have given here about safety and health more useful.
