Science can save your skin!
If you can feel heat through your gloves, whatever you’re holding is hot enough that you want to find a way to put it down right now. It’s just going to get hotter. You don’t want that on your hands. Literally.
I have to say I didn’t learn this the hard way (unlike a lot of these other tips). When I was a kid, I remember watching a documentary about effects people setting themselves on fire. One of them specifically said that once you feel the heat, you have to start being put out right then, because the cooling effect will take just as long to reach you through the insulation as the heating effect.
One day, I was handling a light and j-u-s-t started noticing my gloved hand getting warm. I immediately set the light down and then monitored my hand. Sure enough, it kept getting hot for a few seconds, then started cooling down.
Science for the win!
