- Buyer's Guide
A worker steps up to an abrasive wheel grinder and places a piece of metal against the wheel’s spinning surface. But because the machine was not adjusted correctly, the metal catches in the grinder. A split-second later, the grinding wheel explodes, sending stony chunks, as deadly as shrapnel, shooting through the shop. The worker drops lifeless to the floor.
Tragic scenarios like that have been known to happen in workplaces across the country. An Occupational Safety and Health Administration (OSHA) examination of 27 grinder wheel accidents in an eight-year period revealed that 26 percent of those accidents resulted in employee deaths.
“Because abrasive wheel grinders are everyday equipment in workplaces nationwide, many workers become complacent about their hazards,” said Benjamin W. Mangan, founder and president of MANCOMM, a company which develops and publishes regulatory compliance products. “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.”
To help America’s workers stay safe, MANCOMM developed and released the Grinder Safety Training CD. This CD can help workers to improve safety and minimize risk by focusing on a personal protection system for pedestal and bench grinders. Topics covered include personal protective equipment, grinder and grinding wheel RPM compatibility, ring tests, grinding wheel installation, guard adjustment, and aluminum oxide grinding wheels. The Grinder Safety Training CD is the first release in MANCOMM’s new Safety Interactive Training Experience (SITE) product line. SITE products use multimedia presentations which actively engage trainees in user-based interactions.
A Grinder Safety Awareness Quiz
How familiar are you with abrasive wheel grinders and their safe operation? Take this quiz and find out. These questions were derived from the audio portion of the MANCOMM Grinder Safety Training CD.
This quiz offers an answer selection for each question. The skill checks on the actual Grinder Safety Training CD are not “multiple guess”, but multimedia demonstrations. Once the employee passes the CD’s interactive skill checks, you will know they can operate a pedestal and bench grinder safely.
1. Why should eye protection be used when operating a grinder?
2. Which of these are forms of personal protective equipment you may need while using a grinder?
3. Why shouldn’t you wear jewelry while operating a grinder?
4. Why would you want to tap a grinding wheel with the non-metallic handle of a screwdriver?
5. When gauging the compatibility between a grinder’s RPM and a grinding wheel’s RPM, remember:
6. When you need to put a new wheel on your grinder, what should you do with the wheel first?
7. How much of a gap should there be between the work rest and the face of the grinding wheel?
8. If your grinder requires repairs, what kind of replacement parts should you use?
9. The wheel hole diameter and the grinder arbor size are not the same. What can you do to make the wheel workable?
10. What kind of material can you grind with aluminum oxide grinding wheels?
How many wrong answers are permissible? In the workplace, it is zero. Whenever workers operate an abrasive wheel grinder incorrectly, such incidents raise the possibility of accidents, injuries or death, which in turn can lead to workers’ compensation expenses, raised insurance premiums, lost productivity, lowered employee morale, and OSHA penalties.
“In the workplace, knowledge is power,” Mangan said, “and we want all workers to have the power to work safely and with skilled confidence. A knowledgeable worker is a happy, productive worker.”
