Cancers presumed to be caused by exposures in firefighting

Issue: BCMJ, vol. 53, No. 4, May 2011, Page 197 WorkSafeBC

Under the Workers Compensation Act, when a firefighter who was regularly exposed to the hazards of a fire scene contracts a prescribed occupational disease, the disease must be presumed to be due to the nature of the worker’s employment as a firefighter. 

The Firefighters’ Occupational Disease Regulation lists the following nine cancers as prescribed occupational diseases that are causally related to the occupation of firefighting: 

1. Primary leukemia
2. Primary non-Hodgkin’s lymphoma
3. Primary bladder cancer
4. Primary site brain cancer
5. Primary colorectal cancer
6. Primary kidney cancer
7. Primary lung cancer
8. Primary testicular cancer 
9. Primary ureter cancer

The Workers Compensation Act states that the presumption applies to a firefighter who:

a) Has worked as a firefighter for a minimum cumulative period prescribed for the disease—these periods are set out in the Regulation and are specific to each disease;
b) Throughout the period has been regularly exposed to the hazards of a fire scene, other than a forest fire scene; and
c) Is first disabled after 11 April 2005.

The minimum cumulative period prescribed for each of the nine cancers is set out below: 

1. 5 years for primary leukemia
2. 20 years for primary non-Hodgkin’s lymphoma
3. 15 years for primary site bladder cancer 
4. 10 years for primary site brain cancer
5. 20 years for primary site colorectal cancer
6. 20 years for primary site kidney cancer
7. 15 years for primary site lung cancer 
8. 20 years for primary site testicular cancer
9. 15 years for primary site ureter cancer

There are also minimum non-smoking periods prescribed for previous smokers who contract primary lung cancer. As a physician, if you have a patient who is a firefighter who is diagnosed with one of the prescribed occupational diseases, please advise your patient about the occupational disease presumption for firefighters in the Workers Compensation Act and the worker’s potential entitlement to workers’ compensation coverage. A representative at WorkSafeBC can be reached at 604 279-8158 if there are any questions. 

Please advise your patients to contact WorkSafeBC to see if they are eligible for benefits. Your patient can call the WorkSafeBC Teleclaim number to apply for WorkSafeBC benefits. Teleclaim may be reached at 1 888 WORKERS (1 888 967-5377) or #5377 for Telus, Rogers, and Bell Mobility customers.

Schedule B of the Act
Schedule B of the Act provides a presumption in favor of workers (not specific to firefighters) that a disease was caused by employment if the worker:

• Develops a disease listed in Schedule B; and
• At or immediately before the date of disablement was employed in the process or industry described opposite such disease.

The primary purpose of Schedule B is to avoid the effort of repeatedly producing and analyzing evidence of work-relatedness where WorkSafeBC has concluded, based on the scientific and medical evidence, that there is a substantially greater incidence of the disease in a particular industry or process than there is in the general population.

For example, if a worker contracts mesothelioma, and at or immediately before the date of the disablement was employed in an industry where there was exposure to airborne asbestos dust, the Schedule B presumption is that the mesothelioma was caused by the worker’s employment, unless the contrary is proven.

Similarly, the Schedule B presumption would apply where a worker contracts angiosarcoma of the liver where there is exposure to vinyl chloride monomer.

Above is the information needed to cite this article in your paper or presentation. The International Committee of Medical Journal Editors (ICMJE) recommends the following citation style, which is the now nearly universally accepted citation style for scientific papers:

About the ICMJE and citation styles

The ICMJE is small group of editors of general medical journals who first met informally in Vancouver, British Columbia, in 1978 to establish guidelines for the format of manuscripts submitted to their journals. The group became known as the Vancouver Group. Its requirements for manuscripts, including formats for bibliographic references developed by the U.S. National Library of Medicine (NLM), were first published in 1979. The Vancouver Group expanded and evolved into the International Committee of Medical Journal Editors (ICMJE), which meets annually. The ICMJE created the Recommendations for the Conduct, Reporting, Editing, and Publication of Scholarly Work in Medical Journals to help authors and editors create and distribute accurate, clear, easily accessible reports of biomedical studies.

An alternate version of ICMJE style is to additionally list the month an issue number, but since most journals use continuous pagination, the shorter form provides sufficient information to locate the reference. The NLM now lists all authors.

BCMJ standard citation style is a slight modification of the ICMJE/NLM style, as follows:

  • Only the first three authors are listed, followed by "et al."
  • There is no period after the journal name.
  • Page numbers are not abbreviated.
