Yes I wear a mask when I do labor that kicks up dust or other airborne particles. At first I was afraid my days of farm work were over and that was sad. But eventually I just started doing it again. But with attention paid to lung health. I keep a mask in my shirt pocket when I go outside just in case I end up doing something that kicks up the dust... like chain sawing firewood. When I remodeled an old out building and turned it into a tool shed I even bought a full faced mask with a shield and those canisters on the sides to really give me super duper protection against the fiber glass insulation I was installing. I built a woodshed. I built a composting outhouse and I built a porch for my cabin. I put the tin roofs on my cabin and on the garage and roofs on all the other outbuildings. I installed the plumbing and the electricity. I built the kitchen. I grow a garden and I forage for herbs and wild apples to feed myself year round. I do all of this myself. I'm aware that all of this makes me sound like a rugged man or something . I'm not. I'm definitely a female. I like to make and wear dresses. I also know that I am bragging. I'm bragging to show that a person can overcome illness and keep going. I survived breast cancer and the treatment of it. I survived MAC , and the treatment of it. Those things got me down.. yes they did and I battle depression but I manage to pull myself back up and keep going.
