Test Your Grinder Safety KnowledgeFebruary 1, 2011
Mancomm, Davenport, IA, a publisher of regulatory compliance
products, offers the Grinder Safety Training CD, developed to help fabricators improve safety and minimize risk by focusing on a personal protection system for pedestal and bench grinders. An Occupational Safety and Health Administration (OSHA) examination of 27 grinder-wheel accidents in an 8-yr. period revealed that 26 percent of those accidents resulted in employee deaths.
“Because abrasive-wheel grinders are everyday equipment in workplaces nationwide,” says Mancomm president and founder Benjamin W. Mangan, “many workers become complacent about their hazards. Improper use of a grinding wheel, or the use of one that is defective or damaged, can cause the wheel to break up. And those flying fragments can be deadly.”
The safety-training CD covers a range of topics, including personal protective equipment, grinder and grinding-wheel RPM compatibility, ring tests, grinding-wheel installation, guard adjustment and aluminum-oxide grinding wheels.
While you’re waiting for your CD to arrive, you might have your operators take this grinder-safety awareness quiz, derived from the audio portion of the CD. The answers appear at the bottom of this page.
