Does OSHA require lathes to have a guard or shield?
OSHA requires all rotary equipment to have guards or shields. Most eye injuries in dental labs seem to occur in the model department. Remember that you don’t want to create a greater hazard by installing a shield, for instance, on the model trimmer if it impairs the worker from seeing well enough to perform the task. If you decide not to install the guard, then you need to have the workers wear close fitting safety eyewear or goggles.
