To help protect your wood projects from scratches during finishing, use carpet on one of your workbenches. Then make it a habit to keep all tools and fasteners off of the carpet. Carpeting can also be used in other places around the shop where finished work comes to rest.
Recessed light fixtures can poke into the attic insulation and create a pathway for air leaks. Caulk around them from below with high-temperature flexible caulk.
Never connect generators to your internal wiring. The reverse flow of electricity or "backflow" can injure an unsuspecting utility worker. For extra safety, install a transfer switch that cuts power to your home from the utility pole and switches it to your generator. Have an adequate supply of fuel for your generator and keep combustible materials like gasoline cans away from heat sources. Always fill the generator with fuel in a well-ventilated area while the generator is turned off. Never run your generator indoors or in a poorly ventilated area such as a garage. Generators, like all other engines, exhaust carbon monoxide gas, which can be deadly. Use the appropriate sized power cords to carry the electric load. Overloaded cords can overheat and cause fires. Never run generator cords under rugs or carpets where heat might build up or damage to a cord could go unnoticed.
Giving the power tool time to wind down after a cut is an often-overlooked safety mistake. Even without power, the spinning blade can still do a lot of damage.
