An increasing number of transport corporations are contemplating buying battery-electric vans. Nonetheless, the usage of lithium batteries in autos just isn’t with out danger. This was defined by André Bourassa, specialist in preventing fires and flammable vapors utilizing an encapsulation approach at Hazard Management Applied sciences, throughout a convention on the Through Prévention 2023 convention.

In his lecture entitled “Points and dangers associated to lithium batteries: find out how to shield your self?” André Bourassa reminds us that “lithium batteries are current in virtually all areas of our lives”.

Nonetheless, it’s potential for an accident to occur to the lithium battery. This will likely not end in a small electrical shock, however somewhat a violent hearth that may final for a very long time.

Issues typically come up from not understanding how a lithium battery works correctly. “One of many largest issues is the truth that folks both make particular modifications or, when their charger is flawed, they exchange it with an unsuitable one,” explains André Bourassa.

There are various causes of errors, equivalent to: B. Battery contamination and contamination, overcharging, brief circuit, electrical overload, bodily harm or extreme warmth.

A number of incidents of lithium battery combustion have prompted hundreds of {dollars} in damages. However along with fires, the battery also can launch poisonous fumes into the air and contaminate wastewater.

Nonetheless, there are a number of protecting measures, equivalent to: Comparable to correct packaging, dealing with and transportation of the battery, fuel, warmth and oxygen detection, the usage of automated sprinklers, moveable hearth extinguishers and prevention coaching.

André Bourassa specifies that straightforward, regular hearth extinguishers is not going to be sufficient to fully extinguish the battery hearth. In actual fact, the battery hearth is attributable to warmth inside {that a} easy powder hearth extinguisher can not extinguish. It’s due to this fact advisable to make use of hearth extinguishers manufactured in line with the UNI EN 3-7 customary and which offer rapid outcomes.

Battery storage additionally must be taken under consideration. André Bourassa recommends labeling batteries with a “spontaneous ignition” warning. He additionally talked about Propulsion Québec’s analysis report entitled “Calibration of finest practices for lithium-ion battery storage,” the conclusion of which highlights the effectiveness of the encapsulation approach.

Mr. Bourassa additionally promotes coaching on security rules associated to lithium batteries, danger prevention and the implementation of customized security techniques.

André Bourassa doesn’t neglect the ecological footprint of the battery, regardless of the risks related to it. Whereas he agrees that manufacturing just isn’t as carbon impartial as potential, he acknowledges that the lithium battery is recyclable, not like different “fuels”. “There are individuals who have some reluctance in the direction of lithium batteries, however not all of the oil we burn whereas touring will be recycled. Then again, the battery will be handled on the finish of its life.”
