EMS 3.7.2

Summary: Actions for Safe Storage

Workers must adhere to written safe work procedures when temporarily storing electric vehicles. These procedures may include the following actions:

Activity Procedure
Vehicle Identification: • Clearly label vehicles as hybrid, plug-in hybrid, or battery electric using visible indicators or signage, especially for after-hours deliveries.
Remote Key Storage • Store keys in a designated location away from the vehicle.
• Use lockout and tagging procedures to prevent accidental activation.
Record Keeping • Maintain detailed records of vehicle condition, location, and handling procedures.
• Track lockout tags and access logs for accountability.
Parking Damaged EVs • Park damaged EVs at a safe distance from buildings or combustibles.
• Severely damaged EVs require at least 15 meters (50 feet) of clearance from other vehicles.
Fire Hazard Precautions • Follow NFPA guidelines for storing post-fire or damaged vehicles outdoors with sufficient clearance.
• Notify employees of the presence of damaged EVs and restrict access unless authorized.
Ongoing Monitoring • Regularly inspect stored EVs for signs of thermal runaway, smoke, or sparks.
• Use thermal imaging tools in conjunction with physical monitoring to detect hidden heat sources.
Battery Damage Response • Refer to manufacturer guides for neutralizing leaked electrolytes.
• Be vigilant for signs of battery failure, such as fluid leakage, bubbling sounds, or toxic fumes.
Emergency Response for Fires • Consult fire departments for removal of ejected high-voltage components.
• Allow fires in high-voltage batteries to self-extinguish unless trained firefighters are available.
Post-Fire Removal • Do not park fire-affected EVs in enclosed areas, as hidden fires may persist.
Environmental Considerations • Mitigate environmental impacts from battery leakage or fire-extinguishing runoff.
• Use impermeable surfaces (concrete or asphalt pads) or containment systems to prevent soil or groundwater contamination.
