Firefighter attitudes, norms, beliefs, barriers, and behaviors toward post-fire decontamination processes in an era of increased cancer risk
Firefighters' are exposed to carcinogens such as volatile organic compounds (VOCs) and polycyclic aromatic hydrocarbons (PAHs) during fires and from their personal protective equipment (PPE). Recent research has shown that decontamination processes can reduce contamination on both gear and skin. While firefighter cultures that honor dirty gear are changing, little is known about current attitudes and behaviors toward decontamination in the fire service. Four hundred eighty-five firefighters from four departments completed surveys about their attitudes, beliefs, perceived norms, barriers, and...

NIOSH Firefighter Body Dimension Data Supports Design Changes and Safety
We have come to rely on, and expect firefighters to rush into burning buildings, put out flames, and save lives. Yet, each year many firefighters die in the line of duty and thousands more sustain injuries. For these reasons, researchers at the National Institute for Occupational Safety and Health (NIOSH) recorded and developed the first database of firefighter body measurements (also known as anthropometric information) to improve the design, and ultimately the safety, of fire apparatus and equipment that firefighters depend on to help protect themselves on the job.

Skin sites to predict deep-body temperature while wearing firefighters' personal protective clothing during periodical changes in air temperature
The aim of this study was to investigate stable and valid measurement sites of skin temperatures as a non-invasive variable to predict deep-body temperature while wearing firefighters' personal protective equipment (PPE) during air temperature changes. Eight male firefighters participated in an experiment which consisted of 60-min exercise and 10-min recovery while wearing PPE without self-contained breathing apparatus (7.75 kg in total PPE mass). Air temperature was periodically fluctuated from 29.5 to 35.5°C with an amplitude of 6°C. Rectal temperature was chosen as a deep-body temperature...
The influence of arc-flash and fire resistant clothing on thermoregulation during exercise in the heat
PURPOSE: We evaluated the effect of arc-flash and fire resistant (AFR) clothing ensembles (CE) on whole-body heat dissipation during work in the heat. METHODS: On 10 occasions, seven males performed four 15-min cycling bouts at a fixed rate of metabolic heat production (400W) in the heat (35°C), each separated by 15-min of recovery. Whole-body heat loss and metabolic heat production were measured by direct and indirect calorimetry, respectively. Body heat storage was calculated as the temporal summation of heat production and heat loss. Responses were compared in a semi-nude state and while...
The European, Japanese and US protective helmet, gloves and boots for firefighters
Thermoregulatory and psychological évaluations The purpose of this study was to investigate the physiological and subjective responses of the European, Japanese (JPN) and US firefighters' helmet, gloves and boots for international standardisation. Three experimental conditions were evaluated (clothing mass: 9.4, 8.2 and 10.1 kg for the three conditions, respectively) at the air temperature of 32°C and 60% relative humidity. The results showed that there was no significant difference among the three conditions in oxygen consumption, heart rate, total sweat rate, rectal temperature...
Review of standards for thermal protection PPE in the explosives industry
The suitability of PPE for use against different thermal challenges is often described by way of compliance with British, European or Internationally agreed standards. The review compared the range of test standards currently used for flame protective PPE for both general industrial use and specialist PPE for motor racing and fire fighting tasks with the thermal challenge expected from a range of explosive events. Disparity has been found between the levels of challenge required to pass the test standards and the level displayed by the burning explosive materials – these practical challenges...
Modeling acoustic propagation in a compartment fire
Firefighters unable to move and in need of rescue use an audible alarm to signal for help. Rescue teams can then follow this sound to the firefighter. This alarm is governed by NFPA 1982 : Standard on Personal Alert Safety System (PASS). Introduced in 1983, the PASS has saved many firefighter lives. However, a number of incidents have occurred where the PASS is less effective. There have been incidents where the PASS was heard sporadically on the fireground, or where localization of the alarm was difficult, leading to injury and loss of life. We hypothesized that the temperature field created by...
The effect of firefighter personal protective equipment on auditory thresholds
Communication on a fire scene is essential to the safety of firefighters. Not only to be able to hear and understand radio chatter, but also alarm signals used on the fireground. One such alarm is the Personal Alert Safety System (PASS) device. This device is used to help locate a downed firefighter. One part of this complex problem is the effect of the protective equipment (helmet, eye protection, hood, coat) on hearing. Previous findings have shown the effect of this protective equipment on head related transfer functions using a KEMAR. [Suits et al. (2013, June). Paper presented at the International...
Measuring the acoustic response of a compartment fire
Rescue teams have a small window of time to locate a downed firefighter. Their task is made more difficult due to low visibility, smoke, toxic gases, and high temperatures. In the United States, most firefighters are equipped with a Personal Alarm Safety System (PASS) device that emits an alarm sound, when the firefighter becomes incapacitated. Rescue teams can then follow this sound to the source to locate the downed firefighter. While the PASS device has been enormously successful, anecdotal evidence has shown it fails in some interesting scenarios. For example, cases have been recorded where...
The critical differentiator for the safety of flame resistant garment should be "Proven" vs. "Unproven"
What should be critically important to the ultimate end user is that the garments are flame resistant (FR) for the life of the garment. The FR protection shouldn't wash out, wear out, or fall off, and it should be there every time the garment is taken out of a locker or drawer and worn to work. It is also critically important to look for proven products. The fabric properties most important to wearers of flame resistant apparel are protection, comfort, and overall value. There are large differences among otherwise compliant FR fabrics, including those that at first glance appear quite similar...
Exposure to high temperature environments can result in the thermal degradation or melting of a Self- Contained Breathing Apparatus facepiece lens
During the investigation of firefighter fatalities that occurred from 2002 to 2011, the National Institute for Occupational Safety and Health (NIOSH) found evidence of thermal degradation of facepiece lenses that may have been a contributing factor in three fatalities. In the fatality cases, the firefighters were likely still “on air” at the time they were overrun by extreme thermal conditions; all had their Self- Contained Breathing Apparatus ( SCBA) facepiece still in place; all had SCBA facepieces that displayed extensive damage consistent with thermal conditions that likely exceeded...
Assessment of Factors Affecting the Continuing Performance of Firefighters' Protective Clothing: A Literature Review
There has been some research into the level of damage and changes to important properties of firefighters' protective clothing after exposure to conditions such as elevated temperature and ultra violet radiation. However, at this time, the results are not comprehensive enough to develop a standard procedure to estimate the remaining useful life of firefighters' protective clothing. There is also a need to develop non-destructive techniques to evaluate clothing, for most tests used to evaluate properties of clothing are destructive, and visual cues cannot completely assess the level of deterioration...
