Compressed Gas Cylinders

Q: In healthcare, when calculating the 300 cubic feet of oxidizing gases like oxygen and nitrous oxide, do “air” tanks figure into the calculation?

A: Yes… According to 3.3.128 of NFPA 99-2012, an oxidizing gas is a gas that supports combustion. And, according to 11.1.1, the NFPA 99-2012 Health Care Facilities Code applies to all nonflammable medical gases. So, if the cylinders of compressed air are medical gases, then yes; they apply to the oxidizing gases rule.
