Power Tool Safety in Science Labs
The use of power tools, such as table saws, drill presses, and miter saws, is becoming more common in science and STEM laboratories. All power tools have special mechanical and non-mechanical safety hazards that can result in injuries, including abrasions, burns, and fractures. This blog post describes machine-guarding safety protocols that schools need to develop to minimize such safety hazards.
