BENCH AND STAND GRINDERS DRESSING 1 Wear a face shield over your safety glasses for protection against heavy particles 2 Use a dressing tool approved for the job Never use a lathe cutting tool 3 Inspect star dressers for loose shaft and worn disks 4 Round off the wheel edges with a hand stone before and after dressing to prevent the edges from chipping 5 Use the work rest to support and guide the tool Use a tool holder if one is available 6 Apply moderate pressure slowly and evenly 7 Always apply diamond dressers at the cen ter or slightly below the center, never above Fic 31-25 --Major safety measures to be taken in a wheel dressing operation cedures should be followed Stones of un known composition or manufacture should never be run more than 2500 sfpm and ordi narily not more than 2000 sfpm The size and weight of grmdstones require a stand that is rigidly constructed, that is heavy enough to hold the stone securely, and that is mounted on a solid foundation to with stand vibration Since grindstones are run wet, all possible precautions should be taken to prevent slip ping accidents near the stones Rough con crete or other nonslad floor material is recom mended Grindstones should be carefully inspected for cracks and other defects as soon as they are received from the manufacturer Those not to be used at once should be stored m a dry, uniformly heated room In storage they should be placed so that they will not be damaged Many grindstone failures result from faulty handling and from incorrect methods of mounting Gnndstones should not be left partially submerged in water This practice causes an unbalanced stone that may break when rotated Wooden wedges should not be used on power-driven stones Often, such wedges are dnven excessively tight or become wet and swell In either case, cracks start m the comers of a square center hole, radiate outward, and so weaken the stone that rup tures occur at normal speed After the stone has been centered, the cen tral space about the arbor should be filled with lead or cement Double thicknesses of leather or rubber gaskets, rather than wood washers, should be used wherever possible If wood washers are used between the flanges and the stone, the washers should be J- to 1-m thick and the flanges should be clamped in place by heavy nuts Work rests should comply with the same conditions as those for grinding wheels For dressing or operating power-dnven gnndstones (either wet or dry), exhaust sys tems should be provided to remove dust and wet spray or mist Polishing and buffing wheels Polishing wheels are either wood wheels faced with leather or wheels made of disks of canvas or similar matenal stitched together, with a coat of emery or other abrasive glued to the periphery of the wheels Buffing wheels are made of disks of felt, linen, or canvas, and the periphery is given a Fic 31-26 --Guarding and exhaust provisions for a surface grinding operation 853

Nor is EPA's interpretation of law, as the Court's decision in Loper Brighi makes clear. [06 When EPA's overly expansive interpretation of LEAN leads it to impose unnecessary and ill-informed MACT floor limits on an industry (heat/non-recovery cokcmaking) that EPA recognizes adequately control HAP emissions, its decision is arbitrary and capricious.

This false sense of security can easily lead a worker and/or supervisor to follow work practices which can cause harmful exposures, since they are not aware that disease may develop later.

Chest X-rays were , ,r not, in general, recommended for mass screening purposes, although the possibility that an increased frequency of chest X-ray screening might lead to a reduced case fatality rate was believed to be worth further investigation.

Further, "the literal meaning of a statute need not be followed where the precise terms lead to absurd or futile results, or where failure to allow a de minimis exception is contrary to the primary legislative goal."

Double and Double Triple and Double Fic 25-23 --Reeving tackle blocks Lead line and becket line should come off a middle sheave when blocks contain more than two sheaves The upper and lower blocks then will be at right angles to each other This eliminates tipping and the accompanying losses in efficiency the required breaking strength of the rope New mamla rope of S-inch diameter has a breaking strength of 7700 pounds and, there fore, is the proper size for the load (Syn thetic fibers would have greater tensile strength See Table 26-A ) The safe working load for two double blocks made for rope of 5-inch diameter, as given by a prominent manufacturer for one senes of its standard blocks (regular mortise, inside iron strapped blocks, with loose side hooks, in tended for use with manila rope), is 2000 pounds--the equivalent of the total load m the example The rope should be attached to the block with a thimble and a proper eye splice A mousing of yam or small rope should be placed on the upper hook of a set of falls as a precaution against its accidental detachment Blocks should be inspected thoroughly and frequently, with particular attention to all parts subject to wear Fig 25-23 shows how tackle blocks should be reeved If the sheave holes in blocks are too small to permit sufficient clearance, excessive sur face wear of the rope will occur Likewise, excessive internal fnctional wear on the fibers will occur if the diameter of the sheave is too small for the rope When men are using block and tackle in confined spaces, the pulley block must be guarded so that their hands cannot be caught between the pulley and the rope When blocks and falls are used to lift heavy materials or to hold heavy loads in suspension, as on heavy duty scaffolds, wire rope is more serviceable than fiber rope Portable floor cranes or hoists Portable floor cranes or hoists are hoists mounted on wheels They can be moved from place to place, either by hand power or under their own power They can raise and lower loads in a vertical line, but cannot rotate around a fixed point Portable floor hoists are useful where over head construction, belting, or shafting pre vents the use of overhead hoists or cranes and where more expensive equipment is not justi fied because of infrequent use These hoists are handy for placing work on machines, loading heavy material on trucks, and trans porting material from one location in the shop to another Portable floor hoists usually are operated by hand or by electric power The lifting mechanism ordinarily is either a winch with wire rope and block or a cham hoist Hoists operated by electric power should be effectively grounded to prevent shock m case of short circuit A special ground wire can be used One end is fixed permanently to the frame of the hoist, and the other end is equipped with a device that can be attached to a grounded building column, water line, or other direct-to-ground connection Where conditions permit, it may be ad visable to install sweep guards on the truck wheels to prevent foot injuries when the hoist is moved Truck handles on hoists should be designed 695
