Canadian (CATSA) law on carry-on SCUBA tanks

[BEM]

FYI.

The Canadain Air Transport Security Authority (CATSA) does not permit carry-on SCUBA tanks, but allows them in checked baggage.

The US TSA allows tanks in carry-on (open tanks)
TSA: Compressed Gas Cylinders

So, they could be confiscated in Canada. Air Canada states that it follows the CATSA rules and ALL sporting equipment (including SCUBA) must be "pre-registered"

Anyone done this? We've never been asked for this form.

I've carried one in my checked luggage. I got called to security so that they could check it out. I made sure the valve wasn't in, so that they could check the inside of the tank.

Just pure nuttiness in the form of the written word.

This gets yammered about endlessly, but few take heed of the very specific words shown on the USA TSA rules:

"Compressed gas cylinders are allowed in checked baggage or as a carry-on ONLY if the regulator valve is completely disconnected from the cylinder and the cylinder is no longer sealed (i.e. the cylinder has an open end). The cylinder must have an opening to allow for a visual inspection inside.

Our Security Officers will NOT remove the seal or regulator valve from the cylinder at the checkpoint. If the cylinder is sealed (in example, if the regulator valve is still attached), the cylinder is prohibited and not permitted through the security checkpoint, regardless of the reading on the pressure gauge indicator. Our Security Officers must visibly ensure that the cylinder is completely empty and that there are no prohibited items inside."

Open means open. If you have it taped or in any manner covered and not open to the air, you might be losing a tank.

The Canadian rules went into great detail about removing valves on CO2 tanks, and having them reinstalled by a professional. Okay, so if you re-install your SCUBA tank after it was at -40° and then dumped on the luggage cart in paradise at 94° and 85%rh, who was going to do that required VIP and when?

Rules, rules, rules. If you follow one, you're breaking another.

I have never flew with Air Canada, but have never had to pre-register my gear with Skyservice. You can't pack your regulator's in carry on with Skyservice. I would check because Skyservice is a charter airline and their rules could be different. Better safe than sorry.
