Carbon monoxide in our tanks .. I need to solve this problem

[Reisender]

Never go back to any place you get a bad fill from. Its a systemic problem with how the shop views its customers (profit over safety).

Unfortunately, refusing to go back to a shop because their fills contained CO would mean I can't dive at all. The only fills with zero CO from shops in Saudi Arabia came from the shop I asked to change their filters. Every other shop has been around 5 ppm. I'd like to see less, but 10 ppm is my cut off where I will refuse the tank. And don't even think of seeing tanks with a current hydro. Safety standards in third world countries don't have the same priority that they do elsewhere.

Sounds like it'd be foolish to dive any tanks there without testing for CO, but then I feel the same way for tanks from any provider - things can go wrong anywhere, even for the first time.

Sounds like a great place to buy your own compressor

Secondly he lives in Saudi Arabia where current daily high temperatures are over 40 C (104 F)

Not in January

I started carrying a CO analyzer about four years ago, and won't leave home without it. Threads like this one affirm my practice. If you don't have one, consider on as your next equipment purchase.

Aziz,

Get yourself a CO detector to test the air in your tanks every time.

There are a lot of threads here on scubaboard about this subject and CO detectors.

Good luck!

If I was going to be here long term I would definitely consider it. Not much time left on this contract, so I'm a short timer. In the mean time I make due with testing each tank.
