Active versus passive cooling during work in warm environments while wearing firefighting protective clothing
This study examined whether active or passive cooling during intermittent work reduced the heat strain associated with wearing firefighting protective clothing (FPC) and self-contained breathing apparatus (SCBA) in the heat (35°C, 50% relative humidity). Fifteen male Toronto firefighters participated in the study. Subjects walked at 4.5km/h with 0% elevation on an intermittent work (50min) and rest (30min) schedule. Work continued until rectal temperature reached 39.5°C or heart rate (HR) reached 95% of maximum or exhaustion. One of three cooling strategies, forearm submersion in water, mister, and passive cooling were employed during the rest phases. Findings suggest that there is a definite advantage when utilizing forearm submersion compared with other methods of active or passive cooling while wearing FPC and SCBA in the heat.

Development of a method for the determination of on-site ignition probabilities
The estimation of probability of ignition is a key step in the assessment of risk for premises where flammable liquids or gases are stored. Currently, simple models tend to be used, which assume that ignition probability is a function only of release rate, or cloud size, and do not consider location, density or type of ignition source. Ignition sources on hazardous installation plants tend to be better controlled than off-site sources. However, these measures are mainly designed to prevent the ignition of small releases within defined hazardous areas. This report describes an ignition probability model that has been developed to consider larger, catastrophic, releases that may come into contact with on-site ignition sources within non-hazardous areas and buildings.

Evaluation of CFD to predict smoke movement in complex enclosed spaces - Application to three real scenarios: An underground station, an offshore accommodation module and a building under construction
Computational Fluid Dynamics (CFD) is increasingly used as a predictive tool to demonstrate the effectiveness of modern building designs and emergency ventilation systems to control the movement of smoke in the event of a fire. The objective of this study was to investigate the capabilities and limitations of CFD for predicting the transport of smoke in complex enclosed spaces. Calculations relating to three examples of enclosed spaces were carried out: an underground station, an accommodation module on an offshore platform and a high-rise building under construction. It is concluded that while CFD modelling provides some insight as to smoke generation in the event of a fire, further work focusing on high-sensitivity parameters is still necessary.

A preliminary investigation of post-traumatic stress symptoms among firefighters
This preliminary study investigated symptoms of post-traumatic stress disorder (PTDS) among firefighters in relation to their experience of traumatic events and the availability of social support. Thirty-one UK fire service workers completed an adapted version of the Post-traumatic Diagnostic Scale (PDS) questionnaire. They were also individually interviewed. Rumination and sleep disturbance were the most commonly reported PTDS symptoms. Participants reported having benefited from high levels of social support from within the service and outside. The results suggest that fire service personnel are at risk of developing some symptoms of PTDS; however most had not experienced severe enough symptoms for PTDS to be diagnosed. High levels of social support may play a role in buffering firefighters from the development of PTDS.

Assessment of benefits of fire compartmentation in chemical warehouses
This report concerns the fire protection measures that can be applied in non-pesticide chemical warehouses. Specific advice for the design of such warehousing is lacking, particularly with regard to the minimization of off-site hazards by taking into account the effects of dispersion of smoke. The report discusses the benefit of various compartment wall options in mitigating fire hazards, and describes the development of a model for comparing the risk reduction resulting from the installation of different fire protection measures within a chemical warehouse site. The model considers the relative benefit of fire protection measures in limiting fire spread. The report also discusses potential areas for model improvement.

Cause, type and workers' compensation costs of injury to firefighters
Work-related injury rates in firefighting exceed those for most other industries. However, little is known about the cost of injury to firefighters. In this study, 1,343 claims collected from workers' compensation records collected in northeastern Illinois (United States) between 1992-1999 were analysed in detail. Regression analysis enabled summary statistics to be presented by cause, nature and cost of injury to firefighters. Overexertion accounted for over one third of all injuries to firefighters, typically involving injuries to the back, and was associated with significantly higher costs than other types of injuries. The per-claim average workers' compensation cost of injury to firefighters was USD 5,168 and the average for injuries caused by overexertion was USD 9,715. Overexertion is a costly source of injury to firefighters, although it can probably be reduced through policy intervention.

Comparative analysis of the main methods for evaluating fire hazards
Análisis comparativo de los principales métodos de evaluación del riesgo de incendio [in Spanish]
This article summarizes the characteristics of eight methods for evaluating fire hazards (K coefficient and ALPHA factors method, Edwin E. Smith and G.A. Herpol method, intrinsic risk method, Meseri method, Gustav Purt method, Gretener method, ERIC method, FRAM method), and discusses the conclusions drawn from applying six of these methods to a real case. It turns out that it is difficult make global, unique and definite evaluations of the fire hazard, which is why different methods are available. The choice of one or another of the methods should be made according to the specified requirements and the objectives defined.

Effects of flashfires on building occupants
This report analyses the likelihood of secondary ignition of the interior of buildings, based on the incident heat from a fire event and the duration of exposure to the event. It incorporates evacuation behaviour, making an assessment of the proportion of occupants who do not escape from the secondary fire. Due to the lack of data on the evacuation behaviour relating to external fires, case studies are used to estimate particular behaviour patterns. The key finding of this study is the increased probability of fatalities of building occupants due to multi-point ignition events, as compared to that for a single ignition. The model was used to generate typical scenarios.

Lipid profile of firefighters over time: Opportunities for prevention
Heart disease is the primary cause of on-duty deaths in firefighters, but little is known about their lipid profile. In this study, the lipid profile was evaluated in relation to other cardiovascular disease risk factors in 321 firefighters at a baseline examination. Comparisons were performed for 285 of these firefighters four years later. The average cholesterol level declined from 224mg/dL to 214mg/dL. Conversely, both obesity (body mass index ≥30) and triglycerides (≥200mg/dL) increased over time. The proportion of firefighters taking lipid-lowering medications increased from 3% to 12%. Despite the declines in cholesterol levels and increases in treatment rates, a considerable number of firefighters had persistently elevated cholesterol, and only a minority were receiving adequate treatment.

Incident-level risk factors for firefighter injuries at structural fires
Firefighting is a demanding occupation, involving many hazardous exposures which can result in traumatic injuries. However, there is little epidemiological evidence quantifying these factors. An incident-level case-control study of National Fire Incident Reporting System data was conducted on the association between firefighter injury and incident characteristics. Risk factors included five or more alarms (odds ratio OR=3.85), number of stories (OR=2.49), and at least one civilian injury (OR=3.69). Risk of injury was reduced for fires originating 49 feet and higher (OR=0.57). This analysis suggests that fire site-specific situations such as the number of stories or a civilian injury increase the risk of firefighter injury.

Firefighting efforts may lead to massive fungal growth and exposure within one week: A case report
This article describes a case of extensive fungal growth that occurred in an apartment building as soon as eight days after a firefighting intervention. High concentrations of fungal spores, 107cfu/g, were found when material samples were analysed. Concentrations of airborne fungal spores (104 spores/m3) were also high and increased by two orders of magnitude during the demolition and evacuation of mouldy building materials. The results show that fast and extensive mould growth in a building may take place also in sub-arctic zones, at least during summer. High concentrations of fungal spores are released to the air during the demolition of mouldy building materials and the following clean-up. Therefore, personal protection is necessary during the demolition of contaminated building materials and their evacuation.

Occupational burns from oxygen resuscitator fires: The hazard of aluminum regulators
There were more than 30 incidents of oxygen resuscitator fires in the United States during the period 1996-2002, causing severe burns to fire fighters, ambulance workers, emergency medical service personnel, health care workers and patients. The National Institute for Occupational Safety and Health (NIOSH) was requested to investigate three such incidents. NIOSH conducted site investigations of the incidents, and the oxygen resuscitators were sent to a testing laboratory for analysis of the fire causes. The three investigated fires were associated with aluminium regulators from the same manufacturer, mounted on oxygen cylinders. It was found that the cause of the fires was an initial small ignition in the high-pressure area of the aluminum regulator, which then resulted in a massive burnout. Aluminium regulators used with compressed oxygen cylinders are subject to potentially catastrophic combustion during normal use. Replacement of such regulators as well as education and improved safety practices are needed to reduce this hazard.

Low-back pain and musculoskeletal injuries among fire fighters - Identification and analysis of hazardous situations during vehicle access and the handling of tools
Lombalgies et accidents musculosquelettiques chez les pompiers - Identification et analyse des situations à risque lors de l'accès aux véhicules et de la manutention d'outils [in French]
Due to the nature of their work, fire fighters are vulnerable to musculoskeletal disorders. Statistics show that sprains are among the most frequent lesions. The back is the main location of injury, followed by the feet and the ankles. Body movements, layouts of workplaces and vehicles are among the causes that are mentioned the most often. The purpose of this study was to identify hazardous tasks or situations in relation to fire fighting vehicles, to analyse the tasks and biomechanical constraints and to recommend ergonomic improvements. Various methods of acceding to vehicles were studied at two fire fighting stations. Practices with respect to the handling and use of tools and equipment were studied among 32 experienced fire fighters (28 men and four women) working at nine fire fighting stations. Several recommendations are made in the areas of vehicle access and the handling and storage of tools.

Occupational exposures and risk of hepatitis B virus infection among public safety workers
A questionnaire and seroprevalence survey was conducted to determine the frequency and type of occupational exposures (OEs) and the risk of hepatitis B virus (HBV) infection experienced by public safety workers (PSWs). Of the 2910 PSWs who completed the survey, 6.8% reported at least one OE in the previous 6 months, including needlestick (1.0%), being cut with a contaminated object (2.8%), mucous membrane exposure to blood (0.9%), and being bitten by a human (3.5%). The rate of OE varied by occupation with 2.7% of firefighters, 3.2% of sheriff officers, 6.6% of corrections officers, and 7.4% of police officers reporting ≥1 OE. The HBV infection prevalence was 8.6%, and after adjustment for age and race, it was comparable to the overall US prevalence and did not vary by occupation.

Hepatitis C in urban and rural public safety workers
A sample of 719 Oregon public safety personnel (police officers, firefighters and corrections officers) was tested for hepatitis C virus (HCV) antibody after completing a risk questionnaire. Seven of nine positive enzyme immunoassay tests (78%) were confirmed with recombinant immunoblot assay, yielding confirmed prevalence estimates of 1.2% among the 406 firefighters and emergency medical technicians, and 0.7% in 274 corrections personnel. No cases were observed in the 29 participating police officers. Self-reports of the number of workplace exposures to blood were not associated with HCV positivity, and the number of years of public safety employment seemed to be slightly less for HCV-positive subjects. Two of the seven (28.6%) HCV-positive individuals reported having at least one non-occupational risk factor (odds ratio, 4.3), suggesting the greater relative importance of non-occupational exposures.

Determination of firefighter exposure to polycyclic aromatic hydrocarbons and benzene during fire fighting using measurement of biological indicators
Exposure to polycyclic aromatic hydrocarbons (PAH) and benzene among firefighters was assessed by means of urinary measurements of 1-hydroxypyrene and trans,trans-muconic acid (TTMA), respectively. All urine samples were collected from 43 firefighters during a period extending for 20h following the end of exposure during a fire. A control sample was also obtained from each participant after at least four days without involvement in fire fighting activities. Following exposure to fire, the level of 1-hydroxypyrene exceeded 0.32µmol/mol creatinine value in 38% of the cases. 17 firefighters had measurable TTMA in the urine samples, among which only 6 had concentrations exceeding 1.1mmol/mol creatinine considered to correspond to a benzene concentration of approximately 1ppm. The low exposure evaluations could be due to either low concentrations of the contaminants during fire fighting or to the efficiency of protective equipment worn.

Fire in the tunnel of the A 86 motorway under construction
Incendie dans le tunnel en chantier de l'autoroute A 86 [in French]
This article describes the fire that occurred on 5 March 2002 during drilling work in a tunnel of the future Paris bypass motorway. 19 construction workers at the site were trapped for more than five hours, but were able to escape unharmed thanks to their discipline, training, familiarity with the site (which enabled an efficient rescue effort) and the high level of coordination between the persons responsible for the site and rescue workers. Four fire scenarios had been prepared. Even if none corresponded exactly to this incident, they no doubt helped manage the intervention efforts.

The emulsifier standard EN 1568
Norme émulseurs EN 1568 [in French]
These two articles discuss the contents of EN 1568, a new European standard on emulsifiers having come into effect in March 2001. The first article highlights progress that this standard represents, in particular the fact that fire testing takes place under conditions close to those of real interventions, and the more stringent requirements with respect to heat stability, viscosity measurements and the propensity to form a film. The second article highlights the weaknesses of the NF EN 1568 standards and discusses issues not addressed by these standards (miscibility, compatibility with other emulsifiers and extinguishing agents, ecotoxicity, biodegradability and corrosiveness.

The FRAME method for evaluating fire risk
El método FRAME de evaluación del riesgo de incendio [in Spanish]
This article presents the FRAME (Fire risk assessment method for engineering) method for evaluating the risk of fire in buildings as a function of three parameters: the value (building envelope and contents), the occupants and the activities carried out within the building. The calculations take into account the potential hazard, the admissible risk and the level or protection, together with a number of additional factors such as thermal load, propagation, geometry, floors, ventilation, access, activation, evacuation time, contents, reserves in water and fire resistance.

Work-related injuries among firefighters: Sites and circumstances of their occurrence
To determine the injury ratio, causes and duration of temporal work disability from on-duty injuries among firefighters, a sample of 1503 firefighters from 29 fire stations who were employed between 1994 and 1997 was studied. Data examined included the number of days and cases of work disability due to on-duty injury, personal data (age, work duration) and data on the circumstances of injury. The analysis revealed that the large proportion of injuries (40%) occurred during compulsory physical training, being responsible for 41% of post-injury absence at work. The workers employed for less than one year were at highest risk of injury. Injuries during emergency operations made 25% of all injuries and accounted for 24% of post-injury absence. The frequency of injuries was not significantly aged-dependent, however, the duration of work disability was found to increase by 20% with increasing age of workers.

Mathematical procedure to adjust for the healthy worker effect: The case of firefighting, diabetes and heart disease
This article describes a mathematical procedure to adjust for one component of the healthy worker effect (HWE), namely, the healthy hired effect, such that among firefighters, the exclusion of individuals with diabetes leads to lower-than-expected heart disease deaths. Three examples from real studies are provided to illustrate the application of the mathematical procedure. It can be applied to adjust for other components of the HWE, such as the exclusion of obese individuals and smokers at the time of hire.

Firefighters' hearing: A comparison with population databases from the International Standards Organization
This study investigated firefighters' hearing relative to general population. For five groups of male firefighters with increasing mean ages, their hearing thresholds at the 50th and 90th percentiles were compared with normative and age- and sex-matched hearing data from the standardized ISO and United States population databases (databases A and B, respectively). At the 50th percentile, from a mean age of 28 to a mean age of 53 years, relative to databases A and B, the firefighters lost an excess of 19 to 23dB, 20 to 23dB, and 16 to 19dB at 3000, 4000, and 6000Hz, respectively. At the 90th percentile, from a mean age of 28 to a mean age of 53 years, relative to databases A and B, the firefighters lost an excess of 12 to 20dB, 38 to 44dB, 41 to 45dB, and 22 to 28dB at 2000, 3000, 4000, and 6000Hz, respectively. The results are consistent with accelerated hearing loss in excess of age-expected loss among the firefighters, especially at or above the 90th percentile.

Municipal firefighter exposure groups, time spent at fires and use of self-contained-breathing-apparatus
The objective of this study was to develop better estimates of firefighter exposures for use in future epidemiological studies. The study population consisted of the 1883 firefighters of the fire department of the city of Montreal. The storage and distribution of self-contained-breathing-apparatus (SCBAs) were tracked for 12 months. Time spent at fires and use of SCBAs were calculated. Eight firefighter exposure groups were identified (based on job title, assignment to a fire district and time spent at fires), ranging from no exposures to 3,244min/year/firefighter. SCBAs appear to have been used for approximately 50% of the time at structural fires but for only 6% of the time at all fires. Failure of previous studies to identify homogeneous exposure groups may have resulted in misclassification and underestimates of health risks. The approach used in this study should facilitate the highlighting of exposure/response relationships in future epidemiological studies.
