Lagos Fire Service: Conventional Methods Fail Against EV and CNG Fires

The Federal Fire Service (FFS) Lagos Command has issued a critical warning that electric vehicles (EVs) and compressed natural gas (CNG) vehicles require specialized firefighting techniques and equipment. Chief Superintendent of Fire Badmus Abdulsamad emphasized that conventional firefighting methods are inadequate for these emerging technologies, posing a significant risk to both responders and the public.

According to the FFS, the primary danger in electric vehicles stems from "thermal runaway," a self-sustaining chemical reaction within lithium-ion batteries. This process generates extreme heat that spreads rapidly between cells, making the fires exceptionally difficult to extinguish. Chief Superintendent Abdulsamad stated that firefighters must focus heavily on cooling the battery pack to prevent this thermal runaway from spreading.

Beyond the heat, EV battery fires release a cocktail of toxic and corrosive substances, including hydrogen cyanide, carbon monoxide, and hydrogen fluoride. Furthermore, these vehicles present a persistent hazard due to the risk of reignition; batteries can spontaneously burst back into flames hours or even days after the visible fire has been suppressed.

The Risks of CNG Transition

While EVs present chemical challenges, CNG vehicles introduce mechanical risks. These vehicles utilize high-pressure cylinders that can rupture and create powerful blasts if handled incorrectly during an emergency. Adding to the danger, CNG fires produce pale blue flames that are difficult to see, potentially leading responders to enter hazardous zones without realizing a fire is active.

Infrastructure Under Pressure

This warning comes as Nigeria accelerates its transition toward cleaner transportation to reduce emissions. However, the shift in vehicle technology has outpaced the evolution of emergency response infrastructure. The unique chemistry of lithium-ion batteries and the volatility of high-pressure gas mean that standard protocols are not only ineffective but can be dangerous.

Industry Implications

For the broader transport and insurance industry, these findings highlight a critical gap in safety management. Without specialized training and equipment, first responders face higher risks of toxic exposure and explosive accidents. Additionally, vehicle owners and towing facilities face prolonged hazards, as traditional storage methods may not be safe for a battery prone to delayed reignition.

Future Outlook

As the FFS continues to strengthen its capacity and pursue local and international training for its personnel, the focus remains on updating equipment to match the current energy transition. The agency continues to monitor the deployment of new intervention tools to ensure that the move toward cleaner energy does not come at the cost of public safety.
