When you get to the construction phase of your home renovation project, you must be mindful of your personal safety as well as the safety of people and property that may be in proximity to your work. I wash my hands frequently while working because I come in contact with all kinds of things. I always have hand wipes available. Hard hats, gloves, and safety glasses offer the very basic personal protection. For certain tasks additional safety precautions need to be taken. For instance when working around live electricity, an electrician would need insulated tools and gloves rated for the voltages that he or she works on. Additionally it is important to conduct yourself in a safe manner during construction. Be mindful of heavy lifting or reaching in awkward positions. Use a ladder when working on the ceiling, or anything high for that matter. Chairs, buckets, milk crates, and anything else not made to be stood on, should not be stood on. One bad fall can change your life forever.
