I have a couple of really excessive fears that I never managed to find the name of so I'm asking here.

1 - High pressure containers or just generally anything under pressure. I just fear they will blow up. It gets to the point where I hold spray cans and decoderant cans carefully to make sure they don't drop because I fear they will explode. I've had friends hurt by them before. Also propane tanks and any such things scare the shit out of me and I feel stressed every second I'm near one.

2 - objects under high tension. Metal wires under high tension just scare me, anything from ship lines to an overturned guitar string, I'm just scared it'll snap and give me lasserations or something even though I know they are safe.

3 - massive moving objects. This isn't megalaphobia. I don't have a fear of massive objects. I look at tall towers in awe and massive ships, but as soon as those ships move, or a turbine spins they terrify me. Even if they are far away, just the idea of several tonnes just spinning at that speed is just terrifying and stresses me out. I noticed this with a spinning Arial at an airport and it just scared me.

4 - high floors on buildings. Even if I'm inside, just being on a high story of a building makes me anxious. I don't know if it's just heights but I don't fear airplanes at all so I'm just confused if this is shared or has a name.
