Monticello and Big Lake firefighters responded to a fire on the roof of Twin Cities Die Cast Saturday morning at 9:38 a.m.
Fire Chief Steve Joerg Wright said Wright County Sheriff’s Deputy Missie Meemken reported fire and smoke coming from the roof of the building.
Joerg requested Big Lake send its aerial truck with crew. Monticello fire crews went to the roof and found a exhaust unit burning, Joerg said Saturday afternoon. In the building below the fire was 1,700 pounds of molten magnesium.
Since any introduction of water into the magnesium would have caused an explosion, crews used fire extinguishers on the exhaust unit. Joerg reported the roof membrane had caught on fire. so crews used shovels to remove rock while carefully lifted the membrane.
Joerg sad fire crews carefully applied water to extinguish the fire, making sure to not get any water into the opening.
Weather conditions associated with a heat advisory made the firefighters’ task twice as hard, Joerg reported.
Built in 2000, Twin City Die Cast’s Monticello plant is one of the most modern magnesium die casting plants in the world, according to information posted on the company’s website.
The company machines components for the medical, automotive, hand tool, recreational vehicle, and heavy truck industries that require high quality, cosmetic finishes.
