I did it again. I made a mistake in my answer to yesterday’s posting, which asked the question if signs are required on doors to storage rooms where there is less than 300 cubic feet of oxidizing gases stored. Initially I said yes, citing NFPA 99-2012, sections 220.127.116.11 and 18.104.22.168 which identifies the need for signs on doors to rooms that store oxidizing gases.
But, thanks to my good friend Marge McFarlane of Superior Performance, LLC, she spotted the error and sent me an email identifying it.
If you want the details… here is where I made my mistake: Sections 22.214.171.124 and 126.96.36.199 of NFPA 99-2012 are under the heading of 11.3 “Cylinder and Container Storage Requirements”. Only rooms that store 300 cubic feet of gas or more are required to meet requirements for storage rooms. Since sections 188.8.131.52 and 184.108.40.206 are sub-sections of 11.3, they only apply to conditions identified under 11.3.
So, I took sections 220.127.116.11 and 18.104.22.168 out of context and thought it applied to all rooms storing oxidizing gases, which was incorrect. It only applies to rooms storing oxidizing gases in quantities of 300 cubic feet or more.
I’ve corrected the posting so the mistake is gone, but if you read it and thought you need to add signs on all the doors where oxygen cylinders are stored, please understand the signs are only required if the room contains 300 cubic feet or more.
Sorry… I apologize to my readers. I hope you will forgive me. I strive to be accurate and not make mistakes, but as you can see, understanding and interpreting the standards can be tricky.
