Office of the State Fire Marshal proposes carbon dioxide detectors be placed inside commercial buildings where pressurized CO2 systems are located

These proposed rule changes would require that carbon dioxide detectors be placed inside every commercial building where any portion of a pressurized carbon dioxide vessel system is located. The changes would also, for newly installed systems only, require that the exit points of boiler ventilation piping (both intake and exhaust) be located outside of an occupancy at least 36 inches above grade to prevent carbon monoxide buildup during times of high snowfall. Third, the changes would clarify the inspection cycle for a historical boiler in the event that one or more required inspections are not conducted by the owner or operator. If four consecutive years of inspections are not conducted, this rulemaking would require the owner to start a new cycle of regular inspections at 2-year intervals with an initial inspection that conducts ultrasonic testing (UT) of 100% of the surface of the object using certified UT testing personnel. These amendments would also update the national technical codes incorporated into these rules as required by Section 2 of the Boiler and Pressure Vessel Safety Act, 430 ILCS 75/2.
