Factory automation, lithium batteries present new fire safety challenges

A dayslong fire at a Coupang logistics center in Incheon has highlighted growing fire safety challenges as factories and warehouses become increasingly automated and rely on lithium-ion battery-powered robots, with fire officials prioritizing prevention of flames spreading to a floor housing hundreds of such robots with combined battery capacity equivalent to about 20 electric vehicles. The fire, which broke out on Saturday, was brought under initial control after 61 hours and fully extinguished on Wednesday, raising concerns that existing safety standards may not keep pace with the spread of physical AI and autonomous mobile robots.

The dayslong fire at a Coupang logistics center in Incheon has highlighted growing fire safety challenges, as factories and warehouses become increasingly automated and rely on lithium-ion battery-powered robots, raising concerns that existing safety standards may not be keeping pace. Fire officials said one of their top priorities during efforts to contain the blaze at the site was preventing flames from spreading from the sixth floor, where the fire began, to the fifth floor, where hundreds of lithium-ion battery-powered warehouse robots were housed. They estimated the batteries had a combined capacity roughly equivalent to those used in about 20 electric vehicles. The fire, which broke out on Saturday, was brought under initial control after about 61 hours without spreading significantly to the fifth floor and was fully extinguished on Wednesday. The spread of physical artificial intelligence AI is expanding the deployment of autonomous mobile robots AMRs , automated guided vehicles AGVs and automated storage and retrieval systems ASRS across warehouses and factories, increasi
