Learn MoreLithium-ion batteries used to power equipment such as e-bikes and electric vehicles are increasingly linked to serious fires in workplaces and residential buildings, so it's essential those in charge of such environments assess and control the risks. Lithium-ion batteries are now firmly part of daily life, both at home and in the workplace.
Over the past four years, insurance companies have changed the status of Lithium-ion batteries and the devices which contain them, from being an emerging fire risk to a recognised risk, therefore those responsible for fire safety in workplaces and public spaces need a much better understanding of this risk, and how best to mitigate it.
Whether manufacturing or using lithium-ion batteries, anticipating and designing out workplace hazards early in a process adoption or a process change is one of the best ways to prevent injuries and illnesses.
Some of these electrolytes are flammable liquids and requirements within OSHA's Process Safety Management standard may apply to quantities exceeding 10,000 lb. Many of the chemicals used in lithium-ion battery manufacturing have been introduced relatively recently.
Due to the self-sustaining process of thermal runaway, Lithium-ion battery fires are also difficult to quell. Bigger batteries such as those used in electric vehicles may reignite hours or even days after the event, even after being cooled. Source: Firechief® Global
Do not overcharge batteries. Do not leave batteries connected to chargers after charging is complete. Proper lithium-ion battery storage is critical for maintaining optimum battery performance and reducing the fire and explosion risk.
