I have one to add.
Against my better judgement I cut through the springs that hold open a chest freezer lid. (Instead of unbolting it like I had on a previous freezer) I knew it had tension on it, but I kept my legs to the side and the lid was partly open to relieve some tension. I was on the grass, it had rained recently so I figured when it rocketed out, it would hit the soft ground and be done.
No, that thing rocketed out, bounced off the ground and slammed into my shin. It hurt like a m*^&$%$%
Might not apply to many here. I merely was cutting the lid off so I could use the freezer as scrap bin.
