Have a stupid debate going on about when 30 minute/4500 psi SCBA cylinders should be refilled. Can't find the NFPA standard, but I was taught to refill/change when cylinder is below 90% of rated capacity, which would be 4000 psi.
In the debate, some are saying 2000 psi is "plenty" and leave the cylinder on a pack in service if it is 3000 psi and above. Have seen studies and observed that it is rare for anyone to get 30 minutes from 30 minute cylinder when working, and average working time on a 30 minute cylinder is between 12 and 25 minutes. 3000 or less is insane and/or dangerous, in my opinion.
Anyone have any video/charts or anything else to show people that cylinders should be refilled when they are below 4000 psi?
