NIMS Computer Numerical Control (CNC) Machining Practice Exam

Safety glasses should always be worn in a CNC machining environment to protect the eyes from flying debris, chips, and coolant. These hazards are common during machining operations, and without appropriate eye protection, workers are at risk of serious eye injuries, which can occur suddenly and without warning.

While other personal protective equipment, or PPE, such as hearing protection, gloves, or helmets can be important in certain contexts, safety glasses are universally recognized as essential gear in machining environments due to the high likelihood of eye-related incidents. Ensuring that safety glasses are worn not only helps prevent injury but also promotes a safety-conscious culture within the workshop.
