Brothers and Sisters,
I am reaching out to fire departments internationally to learn more about current policies, procedures, and health and safety guidelines relating to lithium-ion battery fires, with a particular focus on decontamination practices and occupational exposure risks.
My department is a medium-sized, full-time fire service in Canada with HazMat and CBRN techs. We are currently assisting a government agency with research into lithium-ion battery fire suppression methods, specifically LiNiCoAlO₂ batteries. Our firefighters have been directly involved in controlled testing, applying various suppression agents to lithium-ion batteries undergoing thermal runaway.
The objective of the experiment is to evaluate the effectiveness of various suppression products (water having demonstrated the most effectiveness to date). The research also involves characterizing the chemical composition of smoke and gaseous emissions produced during battery failure and fire events, as well as collecting and analyzing suppression water and runoff to assess potential contamination and environmental impacts.
Until recently, our personnel were conducting technical decontamination on scene following testing and operational activities, with contaminated PPE sent for water-based extraction.
However, following new information provided to us from the IAFF and scientists working in this field, we have put a stop to the research while we gather additional occupational health and safety information. Although the expected contamination levels associated with our activities were considered extremely low, we believe a precautionary approach is warranted given the remaining uncertainties surrounding exposure risks, contaminant persistence, and the effectiveness of current decontamination methods as shown in research bellow.
We are interested in information supported by peer-reviewed scientific literature, validated research, occupational exposure assessments, or documented operational experience.
Specifically, we would appreciate information regarding:
Personnel decontamination procedures and PPE cleaning or extraction methods.
Procedures for cleaning and testing contaminated SCBAs, tools, and other firefighting equipment.
Exposure monitoring programs(Ex. Blood testing)
Validated cleaning methods, post-cleaning assessment, and criteria for returning PPE and equipment to service.
As we are located in the eastern part of Canada and are familiar with policies in the North East, we are interested in hearing from departments and research organizations located in central and west coast of North America, as well as those in Australia, New Zealand, Asia, and Europe, where techniques and policies may vary.
Two relevant resources we have identified so far are from TEEX – Lithium-Ion Battery Fires and Emissions Characterization and Recent research published in Fire Safety Journal.
If your department has relevant policies, training materials, research findings, or documented decontamination procedures that you are able to share, we would greatly appreciate your input.
Thank you and Stay safe!
