Lithium-ion batteries have become so prevalent in our lives that it’s almost hard to imagine life before they came along. From electrical vehicles to hand tools to our ubiquitous mobile phones, lithium-ion batteries are everywhere, every day. But while this technology offers numerous benefits, it also poses several significant hazards that vessel operators, industrial facilities and boat yards must address proactively.
It will come as no surprise that there are multiple hazards related to li ion batteries that can cause all manner of damage and injury. Thermal runaway is the most significant but there are also electrical, chemical and other physical hazards galore. It is imperative that operators on shore and on the water have plans in place for the various ‘what ifs’ that could happen.
Much like other potentially hazardous materials on board or in the yard, clear SOPs and ongoing training are the key to a successful risk mitigation strategy. Best practices include conducting thorough risk assessments to identify where lithium-ion batteries are used, stored, charged and disposed of; evaluation of potential hazards associated with each stage; designation of areas for charging and storing batteries, away from flammable materials, high-traffic zones and sensitive equipment and procedures for regularly inspecting batteries and devices for signs of damage, such as swelling, leaks, cracks or unusual odors. Damaged batteries should be immediately removed from service and quarantined for safe disposal. Put together a plan for the safe disposal and recycling of batteries according to local regulations and emphasize that damaged or end-of-life batteries should be handled as hazardous waste. Perhaps most importantly, follow proper charging guidelines (the user manual or manufacturer’s instructions are your friends here) and do not leave chargers plugged in and unattended overnight: A simple outlet or power strip timer that automatically shuts off at the end of shift or other designated time can literally be a life saver.
The marine environment can be particularly hard on lithium-ion batteries. Water, salt and the propensity for vessels and yards to sometimes encounter rugged conditions that can damage batteries during every day operations. Onboard, ensure that lithium-ion battery installations on boats are done by qualified professionals and adhere to marine-specific safety standards and regulations. Additionally, implement safe storage practices for batteries removed from vessels during maintenance or off-season storage, considering temperature fluctuations and potential for damage. Set up strict protocols for charging batteries onboard, ensuring proper ventilation, using approved chargers and avoiding unattended charging, especially overnight. Finally, be aware of employee, crew and guest devices: recently we narrowly avoided a significant claim on a vessel due to a crew member’s rechargeable vape pen overheating thanks to a captain’s vigilance.
By implementing comprehensive mitigation strategies, you can significantly reduce the risks associated with lithium-ion batteries and ensure a safer working environment, a much lower risk of a potentially business ending incident and the health and lives of your team. You’ll look like a star in the eyes of your insurance company, too!
