Three men are in critical condition after suffering severe burns from a house explosion.
A neighbor called the Lansing Fire Department at 12:30 this morning after seeing an explosion on the 900 block of Clark Street in Lansing.
The Lansing Fire Department says there was an explosion at the house. They believe it was caused by a flammable cylinder that exploded. Firefighters are not sure what the cylinder was filled with, or why it was in the house.
They say the house was not being used as a meth lab, but something was being manufactured there. At this time, firefighters are unsure what was being made there.
Firefighters say the house suffered extensive damage and is a total loss.
Two victims were flighted to The University of Michigan's Trauma Burn Center in Ann Harbor, the other victim was taken to the Grand Rapids burn department.
Firefighters say one person suffered burns on over 70 percent of their body. Two victims were burned with second degree burns over 50 percent of their bodies.
The fire department will not confirm the ages of the three victims, but say all three lived at the house. When the fire department arrived on scene, the men were out of the house and being helped by neighbors.
The siding to an adjacent house was damaged, but no other structures were affected by the fire.
It took firefighters about 45 minutes to put the fire out. The fire department is still investigating the cause of the explosion.
