Electric vehicle fire risks and safety protocols addressed

Recent reports and guidance address common misconceptions and safety protocols regarding electric vehicle (EV) fires. Data from the UK’s Department for Transport indicates there is no evidence that EVs are more likely to catch fire than petrol or diesel vehicles, though battery fires present unique challenges.

In the maritime sector, CHIRP Maritime has issued guidance for passenger ferries regarding the carriage of EVs. While EV fire incidents on roll-on/roll-off ferries are considered low-frequency, they are classified as high-consequence events due to the nature of lithium-ion battery failure.

A primary concern is thermal runaway, an uncontrolled chemical reaction that can lead to temperatures exceeding 1,000°C and the release of flammable gases. In enclosed spaces, these gases can accumulate and potentially lead to vapor cloud explosions. Experts emphasize that while the likelihood of an EV fire may not be higher than conventional vehicles, the specific behavior of battery fires requires specialized response and consequence management.
