The State Fire Marshal's Office reminds all centers of the fire risks associated with charging lithium-powered devices, especially wheelchairs and scooters, in resident rooms. No lithium-powered wheelchairs should be charged in a resident's room. This video demonstrates the potential dangers.
While lithium-ion batteries are efficient and long-lasting, they can overheat, catch fire, or explode if damaged, improperly charged, or exposed to extreme temperatures. Charging in confined spaces, using incompatible chargers, or overcharging increases the risk of thermal runaway, a dangerous chain reaction that can lead to battery failure and fire. These fires spread quickly and are difficult to extinguish, creating a severe safety hazard.
To reduce risks, first and foremost, always follow manufacturer guidelines. The Fire Marshall office also suggests avoid overcharging or overheating, keep them dry, and store them in a cool, well-ventilated area, away from heat sources and flammable materials. 
Here's a more detailed breakdown of lithium battery safety precautions:
 
General Handling and Storage:
Follow Manufacturer Instructions: Always adhere to the manufacturer's guidelines for charging, storage, and disposal. 
Store in a Cool, Dry Place: Keep batteries in a cool, dry, and well-ventilated area, away from direct sunlight or heat sources. 
Avoid Extreme Temperatures: Store batteries at room temperature to prevent degradation and potential hazards. 
Protect from Physical Damage: Handle batteries with care, avoid dropping/ puncturing them. 
Keep Away from Flammable Materials: Don't store batteries near flammable materials or ignition sources. 
Prevent Short Circuits: Ensure that battery terminals are not exposed to metal objects that could cause a short circuit. 
Ventilate Storage Areas: Ensure that storage areas are well-ventilated, especially when storing multiple batteries. 
Leak Containment: If a battery leaks, contain the leak and dispose of the battery and any contaminated materials properly. 
Use Protective Clothing: When handling potentially damaged batteries, wear appropriate protective clothing, such as gloves and eye protection. 
 
Charging:
Use the Correct Charger: Always use the charger specifically designed for the type of lithium battery you are using. 
Avoid Overcharging: Don't leave batteries plugged in after they are fully charged, as overcharging can lead to overheating and damage. 
Charge in a Safe Location: Charge batteries on a stable, non-combustible surface, away from flammable materials. 
Monitor Charging Process: Keep an eye on the charging process and ensure that the battery doesn't overheat. 
Don't Leave Charging Batteries Unattended: Never leave charging batteries unattended. 
Use Reputable Chargers: Use chargers from reputable brands to ensure quality and safety.
