Regulated industry sector: Elevating devices - Elevator
A fire started at the variable frequency drive unit, which spread to the adjacent regenerative drive unit. Both the VFD and the regenerative drive unit sustained catastrophic failure. Based on the amount of heat damage contained in the vicinity of the VFD and regenerative drive unit, it is plausible that these units were the original source of the fire, possibly due to age or manufacturer defect.
