Update-3 Injured in Explosion at Hutchinson 3M Plant 13 Apr 18

HUTCHINSON, Minn. (AP) — Authorities say an explosion at the 3M Co. plant in Hutchinson injured three people, one of them seriously.

Hutchinson Police Chief Daniel Hatten says a piece of equipment malfunctioned about 1:30 p.m. Thursday. Hatten says one person was seriously hurt while the other two suffered minor injuries.

All three victims were taken to hospitals.

A 3M representative says the employee with serious injuries was taken to HCMC for treatment of non-life threatening injuries. The other two were treated and released.

The spokesperson says equipment became “upset in the cooling process,” and a small part of the plant remains closed while the incident is being investigated.
