Firefighters suffer more from certain serious diseases than other professions, and in our modern world, the risks are increasing rapidly. To stave off the threats, firefighters must minimize the danger by tackling one main occupational hazard: harmful contaminants that accumulate on clothes and equipment. Decontamination both on site and off may be the only effective solution.

Decontamination of personal protection equipment and clothing can often end up low down on the priority list. After all, your firefighting job has been completed, you've moved out of the hot zone, and the hazard is no longer a clear and present danger. What else is there to do but hop into the truck, go back to the station, get out of your protective gear and slip into something more comfortable?

But the real story is a different one. Proper decontamination is of utmost importance. Sure, you have been protected by your clothing and respiratory equipment in the hazard area – but the gear itself has been directly exposed to harmful substances for an extended period and may still carry on its surface the contaminants from the dangerous environment.

Nasty stuff

Our world gets fuller and fuller of potential and apparent risks in the form of synthetic materials, chemicals, pathogens, carcinogens, bio-hazards, and many other types of health risks. Everyone is exposed to such risks, both at home and at work, but firefighters work with fire, and combustion can generate and release many more substances and render them airborne and breathable and capable of entering your body through the skin.

Firefighting personnel routinely encounter burning plastics, hydrocarbons, combustion gases, acids, metals, aromatic compounds, benzene, styrene, dioxin, formaldehyde and countless other toxins, along with other harmful substances such as asbestos. All of these can cause severe health effects. And firefighters stand a significantly higher risk than others of contracting serious disease, such as testicular and prostate cancer, melanoma and non-Hodgkin lymphoma.

So, there you are, in your rugged, safe, high-quality, high-efficiency protective gear. ‘What have I got to worry about?’ you might ask. ‘I’m protected.’

Perhaps you are – until inevitably, the time comes when you take off your clothing and equipment. This is the critical moment. And not only for yourself: contaminated turnout gear, BA sets, respirators, hoses, and other items leave a long trail of hazards to a whole chain of people.

On-site action

Many firefighting authorities around the world recommend decontamination in the field, often called gross decontamination. Many prescribe dry (brush), wet (water spray) or air (blower) decontamination of the whole person while wearing full protection. Most sources agree that soap and water seem to be the most effective method. Then, after safe removal of the clothing and equipment, the firefighters (after having a shower on the site) are transported back to the fire station dressed in clean clothing with the soiled clothing and equipment in sealed bags, in isolated compartments or separate vehicles.

During the entire procedure, personnel should avoid smoking, eating, drinking, touching skin, or going to the toilet.

Naturally, this means longer periods between finishing the job and going back to the station (some calculate one hour extra). It also leads to the need for special decontamination equipment, such as brushes, tents, showers, air blowers, respirators, protective clothing for cleaners, and more.

This sounds like a great obstacle and a substantial cost for the organization – but what if it prevents personnel from getting seriously ill?

In any case, according to the so-called ‘Skellefteå Model’, the bottom line remains: firefighting personnel must not go back to the fire station in the cab of the fire truck wearing or carrying clothes and equipment contaminated by harmful materials.

Depending on the type and amount of hazards present, an on-site (that is, gross decontamination) checklist could include:

  • Firefighter keeps all clothing and equipment on including SCBA face piece.
  • Assistant hoses down entire person with water or soapy water (alternatively, firefighter uses portable decontamination shower).
  • Run-off water may have to be contained and collected in order to avoid seeping into the soil or remaining on the ground.
  • Firefighter strips off all clothing and equipment and has a shower, scrubbing down all body parts, and changes into clean clothes.
  • No eating, drinking, smoking, touching face or using toilet until after shower.
  • All clothing and equipment is placed in sealed plastic bags.
  • Transport back to base, people and bags in separate compartments.

Note: the above checklist is based on cases where the hazard is known or suspected to constitute a high health risk. Lesser measures can be taken in cases of only light hazards.

Gross decon-tamination on site in portable field shower – 1,000 litres of water per minute.

Back at base

If on-site decontamination is a crucial exercise, then what happens with clothing and equipment back at the fire station is another.

In some brigades, the clothes and equipment are sent off to a professional third-party facility for thorough decontamination. In others, the gear is cleaned at the fire station, either by the firefighters themselves, or by cleaning personnel.

Whichever method is used, it is important to have a strict and clear sequence of safe procedures in place. Otherwise you stand the risk of being contaminated by the decontamination!

While there are countless ways of handling soiled clothing and equipment, a general checklist might comprise:

  • Contaminated clothing and equipment to be cordoned off and isolated from access by unprotected personnel.
  • Personnel to avoid all contact with real, potential, or unknown hazards by wearing protective clothing and breathing protection.
  • All people in the premises to be aware of hazards and trained in appropriate handling and decontamination methods.

‘Round and ‘round it goes

While some fire stations around the world settle for simple soaking of turnout gear and others ignore decontamination altogether, other fire brigades have a bank of washing machines (often called ‘extractors’) for soaking, washing, rinsing and drying clothing and fabrics. But what about BA sets, helmets, visors, boots, masks, cylinders and harnesses?

Nowadays, there are specialized washing machines for those, too. Specially developed for use in fire stations, such devices subject the equipment to powerful water jets, scrubbing away every morsel of debris, dirt and grease from all angles. Some washers can decontaminate 20 breathing apparatus sets — complete with face-masks — in a single hour, or hundreds of helmets, gloves and boots in the same time. Five-minute cycles for BA sets; two-minute cycles for the rest.

Different strokes for different folks

Various fire brigades around the world have adopted widely differing philosophies, methods and equipment when it comes to on-site and off-site decontamination. Practices range from taking decontamination very lightly (virtually ignoring it) to implementing a strict cleaning program after every single firefighting operation. For example, it is not uncommon to have turnout gear cleaned only once or twice per year. Items are simply stored away for the next use, accumulating (and releasing) more and more hazardous materials. Nor is it unusual to do much more to keep firefighters as isolated and protected as possible from their own contaminated clothing and equipment after their job is finished.

Undeniably, though, professional firefighters really do make up a significantly larger group of disease sufferers than other sectors of workers. There is no excuse for ignoring the real risks firefighters are exposed to – apart from the fire itself.

Decon Procedures and Firefighter Health

Assessing the Skelleftea Model for the U.S. Fire Service

By Todd J. LeDuc
05/09/2018


Of late, the American fire service has been discussing and focusing on occupational cancer exposure and potential mitigation strategies. Such mitigation strategies and prevention approaches have included numerous occupational changes: exhaust extraction systems, enhanced personal protective gear cleaning, hood and glove exchange programs, more thorough and aggressive decontamination approaches, and early detection and medical screenings. A National Institute of Occupational Safety & Health (NIOSH) study of more than 30,000 Philadelphia, San Francisco, and Chicago firefighters found elevated rates of certain cancers over general population control. The American fire service certainly may benefit from reviewing global fire service cancer practices, particularly in light of their aggressive practices aimed at a “well” firefighter from the point of contamination forward.


Reducing the Impact of Heat Stress within the Fire Service Industry

Evaluating key factors contributing to, and exacerbating, the heat stress risks within the fire service industry, readers can explore important preventative protocols to help alleviate the hazard.



RELATED: How Can We Kill the 'Toxic Snake' of Cancer? | Goldfeder: I Am Really Uncomfortable

Sweden has adopted an approach to post-products of combustion exposure--very much like what has been common practice in the United States when it comes to decontamination of hazardous materials environments and exposure (see video below, "The Skelleftea Model.")The notion of hot, warm, and cold zones, and of gross and fine decontamination, are well-accepted in this operating environment. We know from continued research and evidenced-based data that exposure to products on combustion contaminate our personal protective equipment and, in many cases, our skin, being absorbed into our circulatory system.  As such, our approach to post-carcinogen exposure demands due diligence and accountability to ensure we remove as much of the carcinogenic product as early as possible.



This focus should be on the immediate brushing and, if possible, scrubbing of personal protective gear to remove decontamination. In addition, whenever possible, gross and fine decontamination on the fireground should be undertaken, including using body wipes. Firefighters should concentrate on areas of the body that have been demonstrated to have higher than normal rates of absorption, especially when overheated, thereby expand body pores. Areas of the body where large blood vessel are just below the surface--such as the carotids (neck), abdominal (thoracic) and femoral for the lower extremities--are areas that have large arterial blood supply and can absorb and circulate rapidly. Although awareness campaigns of “showering within the hour” have taken proactive steps towards decontamination, when logistically feasible aggressive measures should be taken as soon as possible to limit the amount of carcinogenic byproducts being absorbed into the bloodstream.

More thorough personal protective gear cleaning should be untaken as soon as possible, as well with extractors/gear washers and removal of any embedded carcinogenic products. Some departments have been swapping hood and gloves on scene to control contamination until they can receive appropriate cleaning, and issuing members clean replacements on-scene. Each department may have particular challenges when it comes to such an approach. The essence of this model is to control and remove as much carcinogenic exposure as soon as possible.

We all understand that firefighting has inherent risks associated with it. We also know  that we have occupational exposures to products of combustion that are linked to elevated rates of certain types of cancer when compared to general population controls. As such, it is incumbent on each of us to take proactive actions to decontaminate ourselves and our personal protective equipment. The early we can decontaminate thoroughly, the more we can mitigate our occupational cancer exposure and risks.

As evidence-based research continues to evolve, our understanding and response to further mitigation strategies will certainly continue to develop- in the meantime, take action to protect yourself!



Model Behavior - A simple way of minimizing firefighters’ exposure to hazardous chemicals on the job, after the job, and between jobs...

Into the unknown

As the Skellefteå Model focuses on unknown hazardous substances, the subject of combustion gases plays a major role in the program. Heat and flame may generate more than 400 different harmful substances, including benzene, dioxin, formaldehyde, polyaromatic hydrocarbons, and vinyl chloride – and that’s only from 7 common plastics. In a house fire, many more combustion gases are generated.

The firefighter may be exposed to these hazardous substances in three ways: inhalation, skin absorption, and swallowing.

  • Inhalation is simple to understand: if respiratory protection is not worn – even for a very short time – the firefighter will inevitably breathe in airborne materials.
  • Skin absorption can be deceptive. Not only is any opening in the turnout gear a possible entry point for contaminants, but just touching your skin with a dirty glove is a certain way of letting foreign materials reach the skin. This is particularly important when it comes to removing soiled clothing and equipment after the job. Add to this that chemicals commonly are absorbed more readily by warm and sweaty skin.
  • Swallowing hazardous materials can happen when not wearing any respiratory protection, or momentarily removing the respirator. Most ingestion happens after a job is finished, when the firefighter perhaps has some food to eat, enjoys a sweet or a bubble gum, takes a drink, or smokes. Bottles, dishes, packaging, and one’s own fingers may be contaminated. Furthermore, just swallowing saliva may ‘activate’ harmless substances into hazardous ones.

These three means of entry into the body are insidious. The absence of detectable characteristics in many hazards may lead to failure to wear personal protection when it is needed.

Some firefighters may resort to simple but largely ineffectual practices, such as breathing through the nose in the belief that the nose hairs will filter out airborne hazards (false), hold one’s breath or try to breathe less (counterproductive), or breathing into the elbow or collar (useless).

It’s in the mix

One problem in firefighting situations is that not only may there be unknown contaminants present, but often more than one. One chemical blending with another can cause far greater damage than each substance on its own. As mentioned, a contaminant may be harmless unmixed, but might become harmful when mixed with saliva. The combined effects of more than one chemical can be graded as follows:

  • No effect.
  • Added effect (each substance adds its own harmful effect).
  • Counteractive effect (the substances cancel each other out).
  • Synergistic effect (the combined effect is greater than that of each chemical).

Impact of Fire Suit Ensembles on Firefighter PAH Exposures as Assessed by Skin Deposition and Urinary Biomarkers
Håkan Wingfors Jenny Rattfelt Nyholm Roger Magnusson Cecilia Hammar Wijkmark

Abstract

Over the past 10 years, a number of safety measures for reducing firefighters’ exposure to combustion particles have been introduced in Sweden. The most important measure was the reduction in the time firefighters wear suits and handle contaminated equipment after turn-outs involving smoke diving. This study was divided into two parts, those being to investigate the level of protection obtained by multiple garment layers and to assess exposure during a standardized smoke diving exercise. First, realistic work protection factors (WPFs) were calculated by comparing air concentrations of the full suite of gaseous and particle-bound polycyclic aromatic hydrocarbons (PAHs) inside and outside structural ensembles, including jacket and thick base layer, during a tough fire extinguishing exercise using wood as the fuel. Second, during a standardized smoke diving exercise, exposure was assessed by measuring PAH skin deposition and levels of eight urinary PAH metabolites in 20 volunteer student firefighters before and after the exercise. The average WPF for the sum of 22 PAHs was 146 ± 33 suggesting a relatively high protective capacity but also indicating a substantial enrichment of contaminants with a risk of prolonged dermal exposure. Accordingly, in the second exercise, the median levels of skin-deposited Σ14-PAHs and urinary 1-hydroxypyrene significantly increased 5-fold (21 to 99 ng/wipe) and 8-fold (0.14 to 1.1 µmol mol−1 creatinine), respectively, post exposure. Among the PAH metabolites investigated, 1-hydroxypyrene proved to be the most useful indicator of exposure, with significantly elevated urinary levels at both 6 h and 20 h after the exercise and with the strongest correlation to dermal exposure. Metabolites from two-ring and three-ring PAHs were eliminated faster while levels of 3-hydroxy-benzo[a]pyrene did not meet the detection criteria. The results from correlation studies indicated that dermal uptake was a major route of exposure in accordance with previous findings. To summarize, this study shows that some of the newly adopted protective measures were correctly implemented, and should continue to be followed and be more widely adopted.



The Push For Clean PPE And Healthy Fire Fighters
In the past decades, firefighters have been glorified for their tough and dirty exteriors that demonstrate their heroic efforts to fight fires and save lives.Soot covered turn out gear often served as a badge of honor, illustrating how courageous these men and woman are in their day to day job.

Recent research, however, has suggested that the fire flames are not the only battles our fire fighters are fighting. One other unforeseen battle is cancer.

Combustion by-products are pollutants that firefighters are exposed to when encountering fires. These contaminants include benzene, formaldehyde and even asbestos, which are known or suspected to cause cancer. In 2013, the U.S. Fire Administration (USFA) and National Institute for Occupational Safety and Healthy (NIOSH) announced that their multi-year study of a group of 29,993 U.S. firefighters concluded that they are at higher risk of cancers of the digestive, oral, respiratory, and urinary systems when compared to the general population. Although many of these exposures are inevitable in this field, there are unnecessary exposures that can and should be eliminated to reduce the overall risk. One way to do this is through the proper washing and drying of personal protective equipment (PPE).

Turnout gear becomes heavily saturated with carcinogens after an encounter with fire. The contaminants are not only on the outside of the gear, they become embedded in the fibers of the material. Firefighters take extra precautions not to inhale harmful toxins during the line of duty, however, they overlook that these hazardous particles are left with them on their PPE to be absorbed through the skin or ingested.

Podab Inc., a commercial laundry manufacturer based in Sweden, has exclusively partnered with the organization ‘Healthy Firefighters’ to aid in the prevention of carcinogenic exposures through proper washing, drying, and handling of contaminated gear. Stefan Magnusson, the founder of ‘Healthy Firefighters’ and a firefighter himself, has developed a method of disposing dirty PPE through properly extracting and containing it immediately after an exposure so that it can be washed and dried promptly upon arrival to the station. He emphasizes that for this procedure to be effective, washing and drying must be done with equipment that can clean and dry it quickly enough so that it can be re-used again as soon as possible.

Stefan said, “The heavy duty turnout gear is absolutely essential to keep firefighters safe, however, it is important to realize that after attending an incident the PPE can also act as a potential danger. Soot and other particles can contaminate the garments, making them a health hazard for our firefighters. In order to prevent this contamination, PPE should be removed immediately after every operation and washed and dried in a timely manner.”

Podab presents a complete range of washing and drying equipment that has been developed in cooperation with Healthy Firefighters. It has developed the FC20 Protective Gear Drying Cabinet specifically to dry turnout gear. This cabinet was the first drying cabinet on the market with the unique ability to dry PPE from the inside and outside by directing hot air through its hangers, significantly cutting drying time.

The FC20 bears a crucial component to the decontamination of PPE. Fire stations across the globe will be more likely to wash their gear if they can have it dry and ready to re-use as soon as possible. Damp turnout gear can be just as dangerous as dirty gear. If gear isn’t fully dried, the moisture left can turn into steam during a fire and subject the firefighter to burns. Any moisture left in the gear can also mold or mildew. The FC20 cabinet is equipped with humidity tracking system (HTS) that measures the level of humidity every second to determine exactly when textiles are dry, eliminating any risk of dampness.

These cabinets are a predominant feature in fire stations across Sweden. By spreading awareness about the importance of clean PPE, Podab and ‘Healthy Firefighters’ hope to aid in the prevention of cancer in our firefighters worldwide. Our mission is to help protect the men and women who protect us.
