THE IMPORTANCE OF GRINDING & CUT-OFF WHEEL SAFETY:
For some time, grinding wheel manufacturers have been involved in compliance with, and publishing information about, the safe use of these products. One of these basic documents is the American National Standards Institute ANSI B-7.1 1988 & Addendum entitled "Safety Requirements for the Use, Care & Protection of Abrasive Wheels". The safe use of abrasive wheels relies upon common sense, and recognition of these two factors: GRINDING WHEELS CAN BE BROKEN. ROTATING WHEELS DEVELOP STRESSES, WHICH CAN CAUSE THE WHEEL TO BREAK. Since wheels can be broken, they must be handled, stored and used with care. Because rotating wheels develop stresses, their safe operating speed must never be exceeded. Ultimately, the user assumes responsibility for carefully selecting, properly handling, and safely using any abrasive grinding or cutting wheel. RESPONSIBLE HANDLING OF ABRASIVE PRODUCTS: This is not intended to be a complete guide to the use, care and protection of abrasive wheels. All users should read and familiarize themselves with "American National Safety Standards" (ANSI B-7.1) for complete safety and use requirements. NEVER use a wheel that has been dropped. The impact may have caused cracks that will result in breakage. NEVER force a wheel onto the machine or alter the size of the arbor hole. Don’t use a wheel that fits the arbor too loosely. NEVER exceed maximum operating speed of the wheel. NEVER use dirty, nicked, warped or sprung mounting flanges. Don’t tighten mounting nut excessively. NEVER grind on the side of the wheel, unless the wheel is specifically designed for that purpose. NEVER start machine without safety guard in place. NEVER jam work into the wheel. Don’t cut or grind material for which the wheel was not designed. NEVER stand directly in wheel’s plane of rotation when machine is started. NEVER forget that cutting and grinding wheels are dangerous when misused or improperly handled. ALWAYS select the right wheel for the job. ALWAYS use the right equipment and machines. They should be maintained and checked regularly, and any substandard conditions should be corrected before use, for safety and efficiency. ALWAYS inspect, handle and store wheels in a careful manner. Wheels should be stored horizontally on flat surfaces. Do not lean wheels against equipment, or roll wheels on the floor. ALWAYS use wheel guards or protective hoods. Certain small sizes, and cones & plugs (type 16, 17, & 18) are exceptions. Refer to ANSI B-7.1 for details. ALWAYS use proper mounting procedures for wheels, particularly for cones and plugs. ALWAYS wear safety glasses or other suitable eye protection equipment. ALWAYS check maximum wheel operating speed against rated speed of equipment. Do not over-speed wheels. ALWAYS determine that mounting flanges are at least the minimum diameter specified in ANSI B-7.1 (section 5). ALWAYS run machine at operating speed for at least one minute (with guard in place) before cutting or grinding. YOUR SAFETY IS OUR CONCERN Magnum Abrasives products are manufactured under strict quality controls and specifications. We use only the highest quality grains, bond systems, and reinforcement fabrics available, all designed for optimal performance, with operator safety in mind. Users of abrasive products should familiarize themselves with ANSI B7.1 and OSHA published standards concerning the proper use, handling and storage of abrasive wheels. SAFETY GUIDE & TIPS SPEEDS - Do not exceed the maximum operating speed established for the wheel. Overspeed is a common cause of wheel breakage. Routine machine speed readings should be made with a tachometer on a weekly basis, or every time a new wheel is mounted. PORTABLE GRINDING - Inspect portable grinders at routine intervals. Flanges should be in good condition, of proper size and shape. Speed governing unit should be operating properly, and DO inspect the grinder to be sure that no damage has occurred as a result of careless or abusive handling. SAFETY GUARDS - Machine guards should always be in place and should conform to requirements in ANSI B-7.1 (section 4). FLANGES - Type 1 cut-off wheels should be mounted between properly relieved flanges with matching bearing surfaces, and be at least the minimum diameter specified in ANSI B-7.1 (section 5). Flanges must be kept in good repair and routinely checked for flatness, burrs or wear. PROTECTIVE EYE WEAR AND CLOTHING - Always wear impact resistant safety goggles. Always wear protective clothing. This guide is not intended as a substitute for a full knowledge of ANSI B-7.1 (American National Standards Institute) and OSHA (Occupational Safety and Health Administration) standards. It is the obligation of the user to be knowledgeable about the safety considerations of the products and tools being used. |
