Portage, MI – Fire at Pfizer manufacturing facility doused by sprinkler system; No injuries

An “over-pressurization” event led to a fire Saturday that damaged equipment and a section of the Pfizer Inc. manufacturing complex on Portage Road, a Pfizer spokeswoman said Tuesday. Kim Bencker, head of communications for Pfizer Global Supply, previously said no one was injured in the incident, but she could not provide more details.

The incident occurred about 10 a.m. Saturday in Building No. 335. “There appears to have been an over-pressurization event and a fire. The fire was immediately extinguished by the sprinkler in the area,” Bencker said Tuesday in an email response to questions.

The fire damaged equipment and caused “limited building damage,” she said. “No employees were in the area of the building where the incident occurred.” “Most of the building is operating normally, and Pfizer is investigating the cause of the incident,” Bencker said.

Kameron Jordan, Kalamazoo district coordinator for the Department of Environmental Quality, said a small fire in Building No. 335 was reported to the DEQ.

“Because of the possibility that water used to suppress the fire could have resulted in runoff of manganese and/or acetone compounds, the retention pond was tested,” he said. “Neither substance was found to be in excess of background levels of those compounds. A final report will be prepared, and no further response is required.”

Tanya Baker, of the Michigan Department of Licensing and Regulatory Affairs, said the incident was not reported to the state, but such reporting is not required in incidents when no employees were injured.
