On this week’s episode of Swarfcast, we’re talking about preventing fires inside of machinery. Our guest is Mike Campo, Midwest Regional Sales Manager with Firetrace International, makers of fire suppression systems and solutions. Fire suppression systems keep businesses, people and equipment safe by automatically detecting and suppressing fires in high-risk equipment, like CNC machines, vehicles and wind turbines.
Mike says that machine tools are most at risk for fires when running oil based coolant while unattended. Suppression systems aim to hold back the fire, helping to mitigate the damage and allowing time for emergency personnel to respond.

Mike shares his background. He has been in the fire protection field for 43 years. He began his career in the engineered fire systems business, protecting data centers and telecommunications centers. He eventually went on to work at Firetrace International, a fire suppression system manufacturer that specializes in protecting critical small environments like CNC machines and wind turbines. (2:50)
Mike talks more about the niche market of working with what he calls micro environments. He says that the Firetrace system is designed for small enclosures, not rooms or spaces where there are people, such as a residential structure. (3:40)
Mike says that sprinklers are a valuable type of fire suppression for structures and are often mandated by local fire codes. He says Firetrace works heavily with the wind energy business to help protect wind turbines, which have structures that do not lend themselves to using sprinkler systems. He says that though an insurance company or local ordinance may instruct a business to purchase a fire suppression system for specific equipment, there are generally no official laws requiring a machine shop to install fire protection systems on its machines.

Mike says the biggest risk for fires in machine shops occurs when machine tools are running unattended using oil based coolant rather than water soluble. (8:40)
Mike says that machine tools running oil create an oil mist that can ignite. Mist collectors can help evacuate some of the mist, but any kind of activity that would cause a spark in the oil mist such as a broken tool or failure of an oil pump, could lead to a violent fire. (10:50)
Mike says fires often occur when machining titanium, stainless steel, and aluminum because a lot of friction can occur, which can lead to broken tools. (12:10)
Mike explains that various Firetrace fire suppression systems correspond to different sizes of machine tools. Different volumes of space inside the machines require differen...
