Safety glasses clear and dark, gloves, steel toe boots, at all times for me. Even if your not creating sparks, picking up dirty stuff with wind blowing can get something lodged in your eye. I usually have at least a long sleeve cotton work shirt, hard hat, and hearing protection in the truck when I need it, a respirator at home for the jobs i know im gonna need it, and even if its not the best having a good first aid kit and fire extinguisher/water in the truck is generally a good idea. I used to have like a professional med kit in the truck but that stayed in a truck i sold down in texas. Now i just got cheaper ones and a turniqute? I got from the army. In colder months i also try to keep matches and warmer clothes in the truck as well. Usually you never need most of that stuff but when accidents happen if your preparred you can minimize the damage. If your unpreparred even minor accidents can turn disaterous real quick.
Also i never do anything inside my house. I'll retrieve things from the houses of others but try to take everything out in one piece and tear it apart outside. And if you see mouse poop wear respirator or dont mess with it.
