SUDBURY — The Sudbury Fire Department was working with a hazmat team to monitor air quality after a three-alarm fire Wednesday afternoon at Cavicchio Greenhouses Inc.

Fire Chief John Whalen said no one was injured in the three-alarm blaze, which was contained to a storage building at the 110 Codjer Lane facility. But due to the presence of fertilizer, a regional hazmat team will monitor the air to make sure it's safe.

"I want to assure residents in the area that we are monitoring air conditions as a precaution and will alert residents to take additional steps if conditions become a concern," Whalen said. "I also would like to thank all of our mutual aid partners, whose assistance was, and always is, invaluable to us."

Firefighters responded at about 2:40 p.m. to Cavicchio's after a 911 caller reported smoke in a storage building on the property. Whalen said he was the first to arrive and discovered a 60-by-100-foot storage building that was fully engulfed in the fire.

He said he called for a second and then a third alarm, which brought in about 70 firefighters.

Firefighters were at the scene for several hours, as the fire caused smoke to spread throughout town. Sudbury firefighters said they received several 911 calls from residents reporting additional fires, but the smoke they encountered had actually spread from the Cavicchio scene.

Several home smoke alarms were also set off, police reported.

The Fire District 3 Hazmat Team was expected to monitor air conditions for several hours and the Fire Department asked residents who live nearby to keep all windows and doors closed, Whalen said.

Cavicchio Greenhouses has been in business since 1910. Today, it cultivates and sustains more than 250 acres containing annuals, perennials and nursery stock, as well as a selection of soil mixes, stone and landscape supplies, according to the business' website. 

The cause of the fire is under investigation by the District 14 Fire Investigation Team and the Massachusetts State Police Fire and Explosion Investigation Unit assigned to the state Fire Marshal’s Office.
