SAFETY FIRST
1. Since no one is a "natural" when it comes to Doing It Yourself, ALWAYS read instructions and pay attention to advice given along with them.
2. When handling materials like wood, metal, or harmful chemicals ALWAYS wear gloves designed for handling them. For example, it may not be wise to handle muriatic acid with regular work gloves. Wear gloves according to instructions designed for that.
3. When using power tools on chop saws, jigsaws, "ripsaws," table saws, etc.. or hanging materials, you may want to wear safety glasses built and designed well enough to protect your eyes from "un-announced" flying particles of sawdust, splinters, and fragments of the material you are working with. Better to keep cleaning them than to risk something landing in your eyes or worse. Keep the lenses clean with professionally recommended hypoallergenic solutions (fluids which are unlikely cause harm to your eyes).
4. When working overhead installing drywall, light fixtures, or otherwise working with anything above your head, ALWAYS wear clean, professionally recommended safety glasses.
5. ALWAYS look for safety directions and other advice before using a power tool, materials, and other things you're not familiar with. Know the risks. Pay attention to the WARNING info.
BE SAFE!
