This amendment was approved as modified per public comment by Michael O’Brian to provide further clarity.

Cost Impact: Will not increase the cost of construction. This is a change in terminology for clarity and will have not technical changes to the codes.

F274-16	IMC [F]502.16, [F]502.16.1 (New), [F]502.16.2 (New),
[F]502.16.1, [F]502.16.2, Chapter 15; IMC [FG] 304.5.1, [FG] 304.5.1.1, IMC [FG] 304.5.1.2, IMC [FG] 304.5.2, IMC [FG] 304.5.3	Modifies text of section [F] 502.16 “Repair garages for vehicles fueled by lighter-than-air fuels”, [F] 502.16.2.1 “Design”, [F] 502.16.2.2 “Operation”, 703.1 “Hydrogen-generating and refueling operations”. Adds new Section [F] 502.16.1 “Repair garages used for the repair of hydrogen-fueled vehicles”, [F] 502.16.2 “Exhaust ventilation system”. Adds new reference standard NFPA 2-2016 “Hydrogen Technologies Code”. Deletes entirety of Section 703.1.1 “Natural ventilation”, 703.1.2 “Mechanical ventilation”, 703.1.3 “Specially engineered installations”.  The exception language in 2311.7.2 (new numbering) was modified to match existing verbiage found in the IMC.

This proposal is a comprehensive fix of the exhaust ventilation requirements for repair garages for hydrogen fueled
vehicles and for exhaust ventilation requirements for the installation hydrogen-generating and refueling operations. The primary goal was consistency and correlation between the requirements found within the IFC, the IMC and the IFGC along with tighter correlation with the requirements of NFPA 2.

Cost Impact: Will not increase the cost of construction. This proposal will reduce the cost of installation by eliminating an internal conflict within the IMC, by correlating all of the ICC codes dealing with this topic, and by providing for tighter correlation with NFPA 2 which the I-Codes already refer to for these types of installations.
