6 FAQs about [The dangers of lithium battery packs]
Are lithium-ion batteries a fire risk?
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.
Are lithium-ion batteries dangerous?
Lithium-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.
What happens if a lithium-ion battery fails?
In addition to this, the way a lithium-ion battery produces power also generates heat as a by-product. In an uncontrolled failure of the battery, all that energy and heat increases the hazard risks in terms of fuelling a potential fire.
Can lithium ion batteries explode?
And even when a lithium-ion battery fire appears to have been extinguished, it can reignite hours – or sometimes even days – later. Lithium-ion batteries can also release highly toxic gases when they fail, and excessive heat can also cause them to explode.
How can lithium-ion batteries prevent workplace hazards?
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.
What happens if you fire a lithium ion battery?
Even after extinguishing a lithium-ion battery fire, there is a risk of reignition. This is the chain reaction of uncontrolled heating can lead to fire or explosion. Signs of damage or thermal runaway include: Mechanical damage such as cracking (from abuse or dropping/collision). Bulging. Popping/hissing. Visible gases venting. Rising temperature.
