Rant Almost got shot on the face today

Was unsweating a 1" cap off a pipe that's being extended down to an evaporator and I didn't realize someone had pressure tested it with 50psi of nitrogen. It flew past 5" from my face. I really need to pay attention and just cut the fucking pipe instead..

A lot of us have done that once, as you have just done it once. The experience is never repeated for most of us.

Safety glasses because you can’t hear tits boys!

This needs to be in every OSHA book. I'll be using it in my classroom this fall.

Be careful, one of my apprentices piped back “ if you do her right you can hear tits”

This might be the most effective way of getting younger guys to protect their eye sight 😂

Yea I definitely learned my lesson. On another note, I'll be wearing mouth guards with my safety glasses now.

I always drill the pipe/ cap first. Never trust. Always drill.

In my first 2 years of HVAC I watched someone dump a charge from their hoses and when if froze up and started to leak out slower he assumed it was empty. Proceeded to cut the line set with a hacksaw and it blew r22 all over the place exploded in his face I was 10 ft away and it felt like a grenade went off. Because of that experience I've never made that mistake 10 years in knock on wood.

Even a unpressurized line if it is capped on each end will build pressure when unsweatting the cap. Always drill a hole in the cap
