JAFFREY - Firefighters called in the Keene Fire Department HazMat Team during a response to Teleflex Incorporated on 50 Plantation Drive Saturday morning.

The special unit from Keene was brought in as a precaution, said Jaffrey Fire Chief David Chamberlain.

In the end a suspected hazardous liquid was determined not to be hazardous, he said.

Firefighters were first called at 6:30 a.m. Saturday for a report of a small amount of smoke coming from an oxidizer unit on the roof.

The unit cleans the exhaust air that comes off the manufacturing process, Chamberlain said.

Teleflex manufactures medical tubing and other tubing at the Jaffrey plant.

No manufacturing was taking place on Saturday, but some employees were at the plant to conduct maintenance.

When firefighters arrived they found the small amount of smoke coming from the machine as well as a small amount of a liquid substance oozing form the bottom of the machine.

No fire or smoke was found inside the building, but the Keene HAZMAT unit was called in just in case.

"It was a precaution for responders and employees at the facility to make sure it wasn't anything to be of any concern," he said.

Firefighters cleared at 12:48 p.m. after it was determined to be safe.

Teleflex will contact the manufacturer of the oxidizer unit for more information, Chamberlain said.

"We were not able to identify it completely what it was, but we were able to determine it wasn't a hazardous spill," he said.

No one was injured.
