Organized chaos. That's how the fire scene is often described. T he adrenaline charged atmosphere feels like a battleground. B ut in this war zone there's no time to develop a battle plan. For the firefight to be successful, action must be immediate. Firefighters have only a few precious minutes to defeat their opponent.
Back in the day, Firefighting was all about racing to the scene, donning a tin helmet and aiming the nozzle at the flames and smoke. And that's pretty much how the general public still perceives the job. But times have changed, and today there’s an art, not to mention a science, to fighting fires.
In terms of extinguishing blazes, today’s firefighters are trained to go face-to-face with the beast, inside the burning building for an "offensive attack." Some fire training experts say that the trick is to tame the fire before extinguishing it, and there are dozens of tactics for doing so. But these strategies often come with extreme risk. Bottom line -- firefighters must make crucial life and death decisions quickly.
For the past 30 years, annual civilian fire deaths have been reduced by 50%. During that same period the number of active firefighters has dropped, some say by 30%. But deaths among firefighters remain the same as they did in 1970, with 112 being lost in the line of duty last year alone.
Even more disturbing are OSHA and the National Fire Protection Association’s predic-tions that fully one-third of the current firefighting force of 1,100,000 will be injured on the job during they year 2007. Of those who will be injured, it is estimated that over half do not have adequate insurance coverage to attend their needs. Is this any way to treat the Bravest?
Maybe Michael Moore's next film should examine how the fire-rescue services do business.

Back in 1993, the US Coast Guard conducted a study dealing with the effects of interior firefighting on the human body. The results of the study are posted in the Coast Guard's Firefighting Initiative, but in short, researchers noted that our body core temperature (even for short exposures), often reaches 104 degrees (F) during the firefight.
(1) Primary Mission:
The primary mission for fire command is to identify, examine and evaluate the physical and mental status of fire-rescue personnel who have been working during the emergency incident or a training exercise. Following a proper survey (see below), it should be determined what additional treatment, if any, may be required.
According to FEMA, "Any activity/incident that is large in size, long in duration, and/or labor intensive will rapidly deplete the energy and strength of personnel and there merits consideration for rehabilitation."
2. Launching The Rehab Operation
(3) Locating the Rehab Sector:
It is crucial for Command to establish The Rehab Sector away from any environmental hazards, or by-products of the fire, such as smoke, gases or fumes. During hot months, the ideal location might include a shady, cool area distant from the incident. In winter, a warm, dry area is preferred.
Regardless of the season, the area should be readily accessible to EMS-Rescue personnel and their equipment, so they may restock the sector with supplies, or in the event that emergency transport is required.
Rehab sites can also be established in the lobbies of nearby buildings, parking facilities, or even inside municipal buses.Misting/cooling systems, heating systems, SCBA refilling and canteen service should be stationed in or around this area as well. During large-scale incidents, like multi-alarm fires, Command should consider establishing Multiple Rehab Areas as the situation warrants.
(4) Coordination and Manning:
Command of the Rehab Area should be assigned to a chief or company level officer, who is designated as the Rehab Officer under most Incident Command structures. The incident itself will determine just how many people you'll need to do the job, however a minimum of two trained EMS personnel should initially be assigned to monitor and assist firefighters in the Rehab Sector. Utilize volunteer canteen or auxiliary members to assist EMS personnel in making "working" members as comfortable as possible.
It is important for command and company level officers to continually monitor personnel for telltale signs of exhaustion, stress, and or physical injury. Individual members are encouraged to report to the Rehab Sector at any time that he or she feels the need to do so. Symptoms may include weakness, dizziness, chest pain, muscle cramps, nausea, altered mental status, difficulty breathing, and others.
Regardless of physical well being, all fireground personnel should report to the Rehab Sector immediately following:
- Strenuous Activity - Forcible Entry, Advancing Hoselines, Ventilation, etc
- The use and depletion of two SCBA bottles
- Thirty (30) minutes of operation within a hazardous/dangerous environment
- Failure of SCBA
(6) Examination of Arriving Personnel
Arriving personnel should be examined by qualified EMS, who should check and evaluate vital signs, and make proper disposition, i.e. return to duty, continued rehabilitation, or transport to medical facility for treatment. The workup should include:.
- Scoring for Glasgow coma trauma scale.
- Checking Pupils
- Checking Vital Signs, such as blood pressure, pulse, breathing rate
- Checking lung sounds
- Administration of a 2-lead EKG, when chest pain or irregular heartbeat is presented
- Skin condition and color
- Body core temperature
- The firefighter should rehydrate
- Oral rehydration and nutrition is recommended in the form of 1-2 quarts of fluids
- Body core temperature should be reduced by cooling the body
- Cool body temperatures gradually using misting systems, fans, etc
- Individuals should be offered Oxygen therapy via nasal canulla or O2 mask. (humidified or Nebulized).
- Standing rest before reporting for further assignment
- The firefighter will only report to manpower staging when presentation is deemed normal by the attending EMS personnel.Note: According to FEMA, Water is the best rehydration agent, however some agencies suggest a rehydration solution of 50 / 50 mixture of water and a commercially prepared activity beverage administered at about 40F. Avoid cooling the body using ice packs or hosestreams. Cooling should be gradual, limiting further shock to the body.
In the event that presentation appears abnormal, the Firefighter should immediately receive additional treatment, especially if conditions persist following fifteen minutes of rest. As is appropriate in most locales, those complaining of chest pain, difficulty breathing and altered mental status must receive immediate ALS treatment and transport to definitive health care. Follow your local jurisdiction's ALS protocols in this event.
