Hazards & Safety

 Crush Hazard (feet).  Any number of things in the woodshop can seriously injure your feet if you drop something on them. Wear eye protection (ANSI Z87 preferred) at all times in the woodshop.

Moving Parts. Many of our power tools have rotating parts, gears, belts, blades, pulleys, gantries, etc.  You should always make sure you have secured loose hair/clothing/accessories at all times in the woodshop.  Additionally, do not wear any kind of gloves when using mechanical equipment, due to snagging risks.

  Wear closed-toe shoes at all times in the woodshop.
 Sharp Implements.  There are many things in the woodshop that can puncture and cut skin.  Many of our tools make louder than normal noises, so wear hearing protection as needed.
 Fume/Ventilation Hazard.  Fine sawdust/particulate, fumes from paint, stains, and other chemicals, and fumes from other areas (such as the metalworking area) may be present.  Always use the available dust collection and ventilation systems.  Wear breathing protection where fumes or fine particulate dust is present.
