Hazard Overview

What is machine guarding?

Machine guarding is the use of barriers that are designed to prevent the contact of an employee's hands or fingers with a hazard created by a moving machinery part. Examples of such hazards are those created by the nip points of an unguarded moving belt, shaft, chain or gears.

What are the hazards associated with machine guarding?

Lack of machine guarding can result in serious physical injury (e.g., broken bones and amputation of fingers), and even death, to employees.

What can I do to protect myself?

Never reach into the pinch points of a moving belt, chain or gears to retrieve an item. Be sure to follow lockout/tagout procedures when it becomes necessary to clear a jam or to remove machine guards to perform repair or maintenance. Be sure not to wear loose clothing when working in close proximity to moving machinery parts.

What resources are available to assist employers?

The machinery and machine guarding presentation can be used to assist employers to train their employees about machine guarding. The presentation should be customized to suit the workplace hazards and conditions.

Additional resource information can be found on the A-Z topics pages for PPElockout/tagout, noise, and respiratory protection.

Lastly, the NCDOL Library offers free safety and health videos and related research assistance on consensus standards (i.e., ANSI, NFPA, NEC). The education, training and technical assistance bureau provides free online safety and health training and outreach services (i.e., speaker's bureau requests, safety booths) upon request.
