But some officials today are saying the boilers are at risk of exploding, due to a new procedure adopted by Detroit Public School.
"The city has an ordinance, a longstanding ordinance, that says if you operate a boiler in the city of Detroit you have to have a licensed engineer on the premises," says Jim Arini, Operating Engineer.
But now DPS wants to have one engineer cover 5 buildings.
The engineers have filed a lawsuit challenging the proposal. But Are these boilers really that dangerous?
Mark Shrupp, COO of DPS says, "not true at all, all of our boilers have at least 9 safety features that all have to be in place and are currently in place as well."
Now DPS says that it will install new technology, a monitor on the low water cut off systems that will monitor the boiler and provide realtime conditions of the boilers to the engineers.
This plan, according to DPS officials, will save the school district about 3 million dollars.
