CO2 fire extinguisher

This is why people advise against pneumatics unless you know what you're doing. It's dead easy to get hurt.

Hello Dave,

I'm not sure if that is a general comment or for me specifically, but I do not think I have done anything that is not safe.

I am a mechanical design engineer, and design pneumatic handling assistors as a profession. Where this has lead me to areas outside my expertise I have the sought the support of experts.
I am concerned that I have done something not in line with the rules.

I'm literally on here asking for advice from people with more knowledge than me.
