It’s almost hard to imagine life before lithium-ion batteries. From electric vehicles to hand tools to our ubiquitous mobile phones, they are everywhere, every day. But while this technology offers numerous benefits, it also poses several significant hazards that vessel operators, industrial facilities, and boatyards must address proactively.
It’s no surprise that Li-ion batteries pose multiple hazards, including thermal runaway — the most serious — as well as electrical, chemical, and physical risks. Whether on land or on the water, operators must prepare for a range of potential “what-if” scenarios.
As with other hazardous materials on board or in the yard, clear standard operating procedures and ongoing training are essential for effective risk mitigation. Best practices include conducting thorough risk assessments to identify where Li-ion batteries are used, stored, charged, and disposed of; evaluating hazards at each stage; designating charging and storage areas away from flammable materials, high-traffic zones, and sensitive equipment; and regularly inspecting batteries and devices for damage, including swelling, leaks, cracks, or unusual odors. Damaged batteries should be immediately taken out of service and quarantined for disposal.
Develop a plan for safely disposing and recycling batteries in accordance with local regulations, and emphasize that damaged or end-of-life batteries must be handled as hazardous waste. Perhaps most importantly, follow proper charging guidelines — the user manual and manufacturer’s instructions are your friends here — and never leave chargers plugged in and unattended overnight. A simple outlet or power strip timer that shuts off at the end of a shift or set time can literally be a lifesaver.
The marine environment can be especially hard on Li-ion batteries. Water, salt, and rugged conditions can cuase damage during routine operations. Onboard battery installations should be done by qualified professionals and comply with marine-specific safety standards and regulations. Store batteries safely during maintenance or offseason, accounting for temperature fluctuations and potential damage. Establish strict onboard charging protocols: ensure proper ventilation, use approved chargers, and avoid unattended charging — especially overnight.
Finally, be aware of employee, crew, and guest devices. We narrowly avoided a significant claim on a vessel resulting from a crewmember’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 protect the health and lives of your team. You’ll look like a star in the eyes of your insurance company, too.
