Q: Can you tell me what the rules are for oxygen usage around hair dryers might be?
A: As you can imagine, the codes and standards cannot have rules for every possible scenario. The NFPA codes and standards primarily deal with the storage of oxygen cylinders, and installation of piped oxygen systems. The NFPA codes and standards do not deal much with the use of oxygen… those standards would likely come from Respiratory Care regulations. To give you an idea, NFPA 99-2012, section 220.127.116.11.1.6 says indoor locations for oxygen shall not communicate with locations storing flammables, kitchens, and areas with open flames. Now, I presume there would not be any open flames around a hair dryer, but you get the idea that a heat source (i.e. a hair dryer) around oxygen is not a good idea. But, there is one standard in NFPA 99-2012 that could be of some help for you. Section 18.104.22.168.4 says: “Nonmedical appliances that have hot surfaces or sparking mechanisms shall not be permitted within oxygen delivery equipment or within the site of intentional expulsion.” Hair dryers are definitely ‘nonmedical’ and they do have hot surfaces, so you could use this section of NFPA 99-2012 to prohibit the use of medical oxygen therapy in close proximity to hair dryers.
