Is there an actual permissible level to be used for tank testing in SCUBA diving?
I am setting up a portable Carbon Monoxide detector. It has low and high level alarms, as well as Time Weighted Average and Short Term Exposure Limit alarms.
"The U.S. National Ambient Air Quality Standards for (Carbon Monoxide in) outdoor air are 9 ppm for 8 hours, and 35 ppm for 1 hour."
My depth limit is 130 fsw since I am only a recreational diver.
Figuring on using four atmospheres for my partial pressures calculations I end up with 2.25ppm for my lower alarm limit and 8.75 for my upper alarm limit. Thus I could dive at 130fsw for 8 hours with a surface reading of 2.25, or I could dive at 130fsw for 1 hour with a surface reading of 8.75, and still be within the U.S. National Ambient Air Quality Standards limits.
Any thoughts?
