There are approximately 170 rubbermaid m40 mobile carts that are used in all areas of our institution.During the last 8 days, we have experience 3 fires associated with these devices.All fires were experienced in the critical care units.Upon opening the units after the fire, it appears that some of the components on the circuit board are getting really hot and catching on fire.At this time, we are not sure if the actual fire is a result of a faulty electrical component such as a capacitor/transistor or if it is the result of heat build up due to excessive lint in the power supply area.All failed units were manufactured in 2011.
