While working on some tombstones this last halloween. I read the can of great stuff foam. It says to wear gloves and safety glasses. I am a safety manager by trade but I will admit I normally do not wear safety glasses when working with the spray foam. I do usually wear gloves as I hate my fingers sticking and having to peel of skin to remove the foam.
That being said, I got a batch of foam cans which were not playing nice. The tops on them broke off when I attahed the spray nozzle or straw however you look at it. I thought hey, I can just used pliers to push the top to the side and still use the foam. Well that broke off the next plastic piece.
Below is a video showing the aftermath of what happens when the remaining plastic piece inside disconnects from the top of the can and turns sideways internally allowing pressure to release.

Great stuff explosion
I hope the video comes through. I tried it two ways as I searched and couldn't figure out how to add it properly.
Here are some afterthoughts.
...The can managed to release all of it's contents in under 2 seconds. Luckily I had it pointed away from me when I broke the second piece of plastic.
... In that time frame I could not have pointed it away quick enough had it been aimed at me. Kind of like looking down the barrel of a gun. It hit the wall over 8 feet away.
... Had it hit me in the face, I wouldn't be seeing to well right now. Fortunately for me, I did in fact have safety glasses on as I was just finishing up sanding a foam piece. So if it had hit me I may have had a chance.
... If the top breaks off, even though you spent $3.50 on the can, do not try to use it.
... Finally, I will from now on wear safety glasses when using spray foam, as you should too.
