Tool and Machine Safety

Machine shops are an integral part of the Cornell University campus.  These shops support the University's infrastructure, advance research operations, and are a focus for many student courses and elective activities.  Machine shops can pose a myriad of hazards that must be taken seriously.  Many of the most frequently cited OSHA safety standards pertain to machine safeguarding.  Nearly 45,000 machinery accidents occur each year in industry, causing severe injuries and fatalities.

Basic Shop Safety Rules

  • Users must receive instruction on each piece of equipment prior to using it for the first time.
