Abrasive Wheels

Hazard Overview

What is an abrasive wheel?

A cutting tool consisting of abrasive grains held together by organic or inorganic bonds. Diamond and reinforced wheels are included. Abrasive wheels are commonly found in bench grinders.

What are the hazards associated with abrasive wheels?

Damaged or improperly maintained abrasive wheels can shatter when run at high or excessive speeds resulting in serious injury or death to workers. In addition, improperly guarded or unguarded abrasive wheels can cause serious injury to employee hands and fingers.

Solutions

What can I do to protect myself?

Conduct a ring test before mounting and beginning to use an abrasive wheel to determine if it has been damaged and is, therefore, unsafe to use. Make sure that work and tongue guards are properly adjusted and wheel guards are in place. Be sure to wear appropriate personal protective equipment, especially eye and face protection and sturdy gloves, when using abrasive wheel equipment.

What resources are available to assist employers?

This job hazard assessment program can be downloaded and customized to fit an individual workplace. Employers are required to perform a workplace hazard analysis to determine what personal protective equipment is necessary to protect employees from continued exposure to identified hazards.

The machinery and machine guarding presentation can be downloaded and modified to address site-specific conditions and hazards.

The A-Z topics page on machinery and machine guarding can provide additional resource information and the Which OSHA Standards Apply webpage can also help identify other standards that may be applicable to your worksite.

In addition, 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. Lastly, the consultative services bureau provides free and confidential onsite consultation regarding worksite safety and health hazards.
