Reversing the cancer trajectory: Fight or flight
Can we do more to prevent firefighter cancer?
August 31, 2020 By Larry Thomas, Chris Biantoro and Len Garis
A new cross-Canada study that shows firefighter cancer risk is still on the rise is calling into question the measures being taken to protect crews.
With the growing awareness that cancer is the leading killer of firefighters, fire departments across the country have been making greater efforts in recent years to decontaminate their members from the smoke, soot and tar that they inhale, swallow and absorb on the fireground.
However, is this enough? A study of firefighter insurance claims from across the country released in summer 2020 showed nearly nine out of 10 death claims in 2018 were due to cancer – up five per cent from 2015. This represents 738 Canadian firefighters’ lives lost to this disease from 2009 to 2018, or about 74 per year.
Published through the University of the Fraser Valley in British Columbia, Canadian Firefighter Fatality and Injury: Trend Analysis of AWCBC Fatality and Injury Claims 2006-2018 reported on 10 years of claims from the Association of Workers’ Compensation Boards of Canada – the latest in an annual series of AWCBC claims analysis – along with other relevant studies and literature. The authors bring a variety of on-the-job and academic expertise to the subject: City of Surrey, Surrey Fire Chief Larry Thomas, Surrey Fire Services strategic planning analyst Chris Biantoro, and Statistics Canada senior advisor and retired Surrey Fire Chief Len Garis.
“Each additional year of data paints a clearer picture of the risks facing Canadian firefighters,” noted Saverio Lattanzio, president of the Surrey Firefighters Association. “It’s alarming to see the numbers for cancer are still rising. This shows that what we are doing now to protect firefighters is not having the desired impact.”
Insurance claims show the trend
The new analysis compared claims from 2006-2015, 2008-2017 and 2009-2018 and showed, in essence, that cancer is responsible for a growing number of deaths while some of the other traditional killers of firefighters – such as traumatic injury and heart disease – are gradually declining. Mental health issues are also becoming more prominent, year over year.
Some of the key takeaways:
- Cancer caused 90 per cent of firefighter deaths in 2018, up from 85 per cent just three years prior. Cancer also caused 33 per cent more time-loss claims (e.g. for treatment) from 2015 to 2018.
- While traumatic injury continues to be the second top killer of firefighters, related deaths dropped 18 per cent from 2015, when it caused six per cent of deaths, to 2018, when they caused 4.9 per cent. While traumatic injuries continue to dominate time-loss claims – making up almost 87 per cent in 2018 – they are also declining over time.
- Circulatory system diseases, such as heart attacks or stroke, continue to be the third most common cause of firefighter deaths but they are also on the decline, causing 20 per cent fewer deaths in 2018 than in 2015.
- Respiratory system diseases, such as emphysema, are the fourth leading cause of firefighter death. While the numbers remain low, the incidence increased almost 18 per cent over the study period, from 1.7 per cent in 2015 to two per cent in 2018.
- Mental health issues continue to rise and are now the fifth top killer of firefighters. Related deaths increased six-fold from 2015 to 2018 (from 0.2 per cent of fatalities to 1.2 per cent), while mental health time-loss claims increased 131 per cent in the same period (from 1.6 per cent in 2015 to 3.7 per cent in 2018).
Reversing the cancer trajectory
As noted in WorkSafe Magazine – a publication of WorkSafe BC – best practices for decontamination procedures include:
- Either scrubbing and rinsing gear at the scene or sealing it in heavy-duty bags;
- Storing bags with dirty gear in the open air for the trip to the hall, with crews wearing full-body painter’s suits;
- Keeping dirty gear out of the hall and designating a separate machine for washing it; and
- Having firefighters wash any exposed skin at the fireground and then shower as soon they return to the hall.
These practices need to continue. However, they take a reactive rather than a proactive approach, and the continuing rise in cancer-related firefighter deaths indicates there is room for improvement.
The answer may lie with deployment strategies, based on the growing body of evidence pointing to exposure time as a significant risk factor.
For example, Robert Daniels et al. established a direct relationship between time spent on the fireground and lung cancer, and between fires attended and leukemia deaths, in their study of almost 20,000 career firefighters titled “Exposure-response Relationships for Select Cancer and Non-cancer Health Outcomes in a Cohort of US Firefighters from San Francisco, Chicago and Philadelphia (1950 to 2009),” published in 2015 in the journal Occupational and Environmental Medicine.
Similar results were found by a study of Ottawa firefighters from 2015 to 2016 by a team of University of Ottawa researchers working with Health Canada, the University of Toronto and the Institut national de santé publique du Québec. Tests of urine and skin wipe samples found firefighters had three to five times more polycyclic aromatic hydrocarbons – which cause cancer and DNA mutations – in their urine after fires than beforehand.
With this information at hand, it is incumbent upon fire services leaders to consider policy changes that would lessen firefighter exposure, for example by limiting the number of events they attend and the time they spend in toxic environments.
