Lithium-ion batteries in educational settings

Lithium-ion batteries are safely used by millions of people every day, powering everything from laptops and tablets to e-bikes and portable chargers. When manufactured and used safely, these batteries aren’t dangerous. However, if lithium-ion devices are over-charged, short-circuited, or damaged, they present a significant fire risk, and it’s now recognised in the Regulatory Reform (Fire Safety) Order 2005 that lithium-ion batteries should be considered in all fire risk assessments in the UK. 

For educational institutions, where fires can have a devastating impact – not only on staff, students, and parents, but the whole community – it’s vital that those responsible for fire safety in schools and other academic premises consider the risks associated with lithium-ion devices.

Where can lithium-ion devices be found in educational premises? 

In schools, colleges, and universities, lithium-ion batteries are used in a wide range of devices, including laptops, tablets, and personal mobile phones. Thanks to their rechargeability and light weight, tablets and laptops are incredibly useful for accessible, flexible, and more enhanced learning experiences. However, it’s also important that schools implement strict safety measures surrounding the maintenance of such equipment, including proper charging practices (with certified chargers) and regular inspections.

E-bikes and e-scooters are also growing in popularity, conveniently aiding students in navigating campuses and surrounding areas. With the London Fire Brigade reporting a fire involving e-bikes and e-scooters every two days in 2023, educational institutions should also consider the fire risks associated with this equipment.

Understanding lithium-ion battery fire risks

Lithium-ion batteries used in educational devices can catch fire if they are overcharged, overheated, damaged, or subjected to manufacturing defects. These incidents can lead to thermal runaway: an uncontrollable, self-heating state that can only be stopped by removing chemicals or heat. Once a lithium-ion battery reaches 60°C or more, it releases toxic and flammable gases, which can ignite and cause rapid thermal runaway in otherwise undamaged cells. This explosive reaction can also lead to collateral fires that spread to surrounding areas.

How can educational premises prevent lithium-ion battery fires?

By preventing the chances of thermal runaway from occurring in the first place, it’s possible to mitigate the risk of lithium-ion battery fires altogether. Schools and educational services can improve fire hazards through strict management of lithium-ion battery procurement, charging, storage, and disposal facilities:

• Regularly inspect devices. Check devices for swollen batteries, cracks, or other damage frequently, replacing or repairing if needed.
• Avoid overcharging devices. At the end of the academic day, unplug devices once fully charged to prevent fires. Avoid charging overnight or for extended periods. 
• Keep an eye on temperature. Don’t expose devices to extreme heat or cold. When not in use, store in a cool, dry environment away from direct sunlight. 
• Prevent physical damage. When devices such as tablets are heavily used by students, the risk of damage can be mitigated by using protective cases.
• Dispose of batteries safely. Old or damaged lithium-ion batteries can be disposed of at recycling centres. Never bin or incinerate them.

• Educate staff and students. Make sure everyone is informed on the proper usage, charging, and storage of devices with lithium-ion batteries.

• Install lithium-ion battery fire extinguishers. Equip schools with fire extinguishers specifically designed to tackle lithium-ion battery fires.

How lithium-ion battery fire extinguishers help

To tackle the unique challenges posed by lithium-ion battery fires, specialised fire extinguishers such as the CommanderEDGE LFX lithium-ion battery fire extinguisher range are crucial for school fire safety. Discharging the water-based liquid inside as a foam-like substance, LFX’s extinguishing agent sticks to battery cells to rapidly put out flames, break down the chain reaction of thermal runaway, absorb heat, and protect from secondary Class A fires. Additionally, CommanderEDGE LFX is fluorine-free, aligning with environmental regulations and contributing to safer, greener schools.

With an NTA 8133 certification on the 6ltr and 9ltr extinguishers, the LFX range ensures robust reliability and effectiveness against lithium-ion battery fires, making it an essential addition to any educational institution’s fire safety equipment.

As lithium-ion battery fires become more common, it’s imperative schools, universities, colleges, and other educational settings prioritise fire safety. The CommanderEDGE LFX lithium-ion battery fire extinguisher offers a reliable solution to protect students, staff, and property from these dangers.
