An Eversource employee is being called a hero for preventing a carbon monoxide incident from turning much worse at a Marion home following last week’s wicked wind and rain storm.

Assessing damage after the storm which caused widespread outages, Eversource employee Ed Gonet noticed a generator running at a home that had power on Front Street in Marion.

“There were really bad fumes and I saw a cord going into the house,” Gonet said, per a post on Eversource’s LinkedIn. “The door was ajar and no one responded. … (I) just couldn’t leave without knowing if there was someone in there after smelling the fumes running into the home.”.

Gonet called 911, and Marion firefighters responded to the home around 9:20 p.m. last Tuesday, a day after roughly 300,000 Massachusetts households had lost power. By that evening, about 60,000 customers had remained in the dark.

Firefighters found a resident sleeping upstairs as they measured low levels of carbon monoxide inside the home but determined there was a potential for levels to rise during the night, according to authorities.

Responders shut down the generator, opening windows and doors to ventilate the home, while the resident was evaluated at the scene and declined to be taken to an area hospital.

“We are thankful that Mr. Gonet was in the right place at the right time this week and reacted quickly when he felt something wasn’t right,” Marion Fire Chief Brian Jackvony said in a release Thursday. “His actions ensured we could respond to and resolve a carbon monoxide incident before it became a tragedy.”

Officials say the incident provides a reminder that generators “should always be placed outdoors facing away from doors, windows and vents. Always follow the manufacturer’s instructions and learn how to use a generator safely before an outage.”

“We are grateful for our partnership with Eversource Energy,” Marion Town Administrator Geoffrey Gorman said in a statement, “and thank all of their team members, including Mr. Gonet, who work diligently during weather events to evaluate outages and ensure power is restored for our residents quickly and safely.”

Gonet hopes that sharing his story will lead to awareness around the “importance of using generators safely,” Eversource said in its LinkedIn post last week.

Colleagues and acquaintances commented on the post, complementing Gorman for his notable deed.

“Safety 1st! Hero! A perfect example of doing the right thing, even when no one is looking!,’ one comment states.
