Question
Hello,

How can I release the pressure from the can? By using up the sprays from the can doesnt mean that I have released the pressure, right?

I appreciate your responses. Thanks.

Thank you for your prompt reply.

I searched online but I couldnt find any information.

I thought the can would explode if I try to tamper with it and cut it open. Is it safe?

Hello,
I would like to know the average wall thickness of aluminum aerosol cans, particularly those containing oxygen or other gases.
I would really appreciate an answer. Thank you.

Unfortuantely I have no idea.  I would suggest either a web search, or if you have some cans available you could cut them open and take some measurements.  Sorry.

You need to be sure and release any pressure from inside the can prior to opening it.  Otherwise the can could explode when you puncture it, which I don't think you would enjoy.  If there's no internal pressure, there should be no issues with cutting it open.

Answer
If the cans have a push down button (like a spray paint can), then you can just hold it down until nothing comes out and all the pressure will have been released.  Even if you've exhausted the can contents, as long as you hear gas escaping keep leeting it out.  Do this in a well ventilated area, as fumes from aerosol cans can be toxic and/or flammable.
