Stay Safe
It is really important to bear in mind that your safety should still be the highest priority when you are working on a project of this magnitude (or any project in general). Many things, such as remodeling, could pose an unreasonable level of risk and could be harmful.
Caution
This is why you have to make sure that you wear clothing that is suitable for work and equipment that is best for your environment. Working at a building site exposes you to different particles of air, including dust, mold, and chemicals. Because of this, you have to wear a respirator.
