Gen set placement

[Fordean]

Ok, new issue Had to inspect issue A client had a 300 am event
At 300 in morning 4 fire trucks and ambulances showed onsite for a central station monitoting alarm (Co2)
I'm guessing they called ( monitoring station) and no answer. Which prompted emergency response. ( note Not many residences have monitoring stations) Upon
Arrival resident answered to there amazement of the large EM response.
Fire department used a sniffer device and followed the Co2 gases from genset 12 feet along foundation then to corner of house went up 8 feet and entered thru soffit vent holes Unit was placed more than five feet from windows and openings as it seems is basis on designs I'm stating this should be 10 feet from any house Why is this being let slide?

Sounds like the house has negative pressure. Do they have a radon removal system? High efficiency gas appliances with power exhaust?
That’s quite a ways for the exhaust gas to travel.

This happened to a family down the street from me in 2021. They cancelled a dinner with parents stating they were all very sick. Parents decided to go check on them that night, realized what was happening and called 911.

The gas was leaking from a tankless water heater on an exterior wall.

I assume you mean CO (carbon monoxide), not CO2 (carbon dioxide).
