Straight answers on gas monitoring, for the people who have to keep the building compliant.

Carbon monoxide monitoring in an enclosed garage is a life safety system, and it is judged by paperwork as much as by hardware. These guides cover what code requires, how often sensors have to be calibrated, what a legitimate calibration looks like, and what to do when an inspector writes you up. Written for property managers, facilities directors, chief engineers and HOA boards who own the problem but do not work on gas detection every day.

Code and compliance

What the codes require, and how they get enforced.

Fire code requirements for parking garage CO monitoringEnclosed garages have to move air, and the code lets you do it with a CO detection system instead of running fans around the clock. Here is what California Fire Code §916.11, the IBC and Cal/OSHA actually require, and where inspectors focus.Read more →How often should garage CO sensors be calibrated?Code sets an annual floor for inspection and testing, but the sensor manufacturer sets the calibration interval, and it is often shorter than a year. How to find the interval that applies to your equipment.Read more →

Service and inspections

What good service looks like, and how to clear a correction notice.

What a real CO sensor calibration includesCertified span gas on every sensor, verified fan response at setpoint, and a documented before and after reading. If none of that happened, your system was checked, not calibrated, and the paperwork will not hold up.Read more →Failed a fire inspection on your garage CO system? What to doA correction notice is not a fine, it is a clock. How to read what the inspector wrote, what they need to see to clear it, and how to close it out before the re-inspection date.Read more →

Common problems

The things that make people call us: something beeping, fans that never stop, a wash-down, a smell.

Beeping or alarm in your parking garage? What it meansThe beeping is almost always the CO panel, and it is telling you one of three different things. How to read the panel, whether the fans responded, and what has to happen to clear it for good.Read more →Garage exhaust fans running constantly? Here is whyFans that never stop usually mean the CO system is not doing its job: a drifted sensor, a fault holding the fans on, or controls someone bypassed. It is the largest controllable electrical load in most garages.Read more →Power washing a garage? Protect the CO sensors firstWash-downs are one of the most reliable ways to kill a set of CO sensors. What to cover before the crew arrives, what to check after, and why a bagged sensor left in place is worse than a wet one.Read more →Exhaust smell in the parking garage? What it does and does not tell youYou cannot smell carbon monoxide. But if fumes are lingering, the air is not turning over, and that is worth acting on. What to check first and which failure mode is the quiet one.Read more →
