Is It Dangerous to Carry a Battery in an Elevator?
Does Carrying Large Rechargeable Batteries in a Lift Pose a Risk?
A viral video shows a man carrying a lithium-ion battery that suddenly explodes in his face after he closes the lift door. The horrific incident occurred near Guangzhou, China, on Friday, October 8, 2021. Sadly, the 28-year-old man, Chen, succumbed to his injuries and passed away 28 days later in the hospital.
The footage shows a person placing a battery in an elevator, after which the battery explodes. The video’s claim suggests that placing a battery in an elevator can cause an explosion due to static charge. However, this claim is entirely false.
It is a Myth
A battery does not explode simply because it is placed in an elevator. The most likely reason for such an explosion is an internal defect in the battery, which may lead to an internal short circuit, where the positive and negative terminals come into contact.
This short circuit can cause a large current flow within the battery, generating excessive heat and potentially leading to an explosion. However, such incidents are rare in high-quality batteries.
To minimize risks, always purchase high-quality batteries. That said, there is no danger in carrying a battery inside an elevator.
Batteries in Confined Spaces
Carrying a battery in an elevator, confined or open space can be potentially dangerous, depending on the type, size, and condition of the battery.
Damaged or defective lithium-ion batteries have been known to catch fire or explode. If a battery (especially lithium-ion) is not properly insulated, its terminals could accidentally short-circuit against metal objects, leading to overheating and even fire hazard.
Some batteries may also release toxic fumes if damaged. Lead-acid batteries (such as those used in cars) can release hydrogen gas, which is highly flammable. If not handled properly, accumulated gas could pose an explosion risk in a confined space like an elevator.
In addition, spilled battery acid (from lead-acid batteries) can cause burns or corrosion. Moreover, large industrial or car batteries are heavy, and improper handling could lead to injury if dropped.
Precautions:
Small consumer batteries (AA, AAA, phone, or laptop batteries) are generally safe in confined spaces and elevators. However, large or damaged batteries, especially lead-acid and lithium-ion types, can pose risks if not handled or disposaled properly. Always follow proper safety measures to prevent accidents.
- Proper Insulation: Always cover battery terminals with electrical tape or place them in a protective case to prevent short circuits.
- Check for Damage: Do not transport a damaged, leaking, or swollen battery in an enclosed space.
- Avoid Overheating: Do not carry batteries near sources of heat, and avoid carrying large numbers of lithium-ion batteries together.
- Proper Ventilation: If transporting a lead-acid battery, ensure the area is ventilated to prevent gas buildup.
- Battery Banks: If carrying heavy batteries (e.g., car batteries), place them in a sturdy container to prevent spills or tipping.
