Frequently Asked Questions (FAQs)



The Purpose for Machine Guarding


Unguarded machinery claims far too many limbs and lives from workers around the world. Such tragedies can be avoided by better training for machine operators, and most importantly, by making machines in the workplace safer.

This course examines dozens of possible ways to safeguard machinery.

This course has been prepared as an aid to employers, employees, machine manufacturers, machine guard designers and fabricators, and all others with an interest in protecting workers against the hazards of moving machine parts. It identifies the major mechanical motions and the general principles of safeguarding them.

Current applications of each technique are shown in accompanying illustrations of specific operations and machines. The methods described here may be transferred, with due care, to different machines with similar hazards. To determine whether or not safeguarding meets the requirements of the standard, any mechanical motion that threatens a worker's safety should not remain unguarded.

The approaches to machine safeguarding discussed in this course are not the only solutions which meet the requirements of the OSHA Machine Guarding standard. Why? Because practical solutions to safeguarding moving machine parts are as numerous as the people working on them. No course or publication could keep pace with all of these solutions or attempt to depict them all.

In machine safeguarding, as in other regulated areas of the American workplace, to a certain extent OSHA standards govern function and practice. This course, however, is not a substitute for the standards. It provides basic technical information and workable ideas which the employer may use as a guide to achieve compliance. It offers an overview of the machine safeguarding problem in the industrial setting, an assortment of solutions in popular use, and a challenge to all whose work involves machines.

Special thanks go out to the U.S. Dept. of Labor, OSHA, for the content and images within this course.
