PORTSMOUTH — A hotel maintenance worker was transported by ambulance to the hospital Thursday after inadvertently mixing cleaning chemicals which, when combined, created a chlorine vapor.

The accident occurred at 10:12 a.m. at the Motel 6 on Gosling Road, said Assistant Fire Chief Steve Achilles. The call was initially reported as a hazardous materials incident which created medical problems for the hotel worker, he said.

Firefighters found the worker on the first floor where he was experiencing “non life threatening respiratory irritation,” said Achilles. An odor of chlorine was detected by firefighters wearing protective clothing who checked for toxicity and ventilated the area, he said.
