Cn December 29, 1982 and January 25, 1983, visits were nade to the above location in response to a request for exemption from requirements of Chapter ul21:l-5 for guarding of several machines. Don Mullins and Dan Hodge of the Columbus Office of the Division participated in the second visit. Kr. 'ark P. Waite, Protective Services Specialist, was contacted. 3. Cn December 29, it had been thought that a safety recommendation had referred to lack of grounding of a Tektronix Model 1*75 oscilloscope used for electrical testing in the Facilities Instrument Shop. It was said that grounding the case of the instrument would nullify t03t results. It was suggested that they contact tha manufacturer of the instrument for informatics on means of grounding or providing equivalent safety If there is a hazard. They planned to do that. It was found on January 25 that the grounding recommendation had referred to a Erookfield Visconeter, #A1369, in Building 70, Room 132. Grounding of it had been provided. 1*. Items l-10 were located in the Weaver Tarns Laboratory in Building 22. At the right side of a Draper loom were a chain drive and a variable pitch V-belt drivo. The company plans to construct and install guards on these. 5. On the #1757 tape loom were three round-section belt drives which operate with low tension. They plan to provide guarding for these. 6. It vculd be possible for jaws of a lathe chuck to protrude radially from the chuck when machining large diameter stock. They plan to guard the chuck. 7. At the right side of the 76II7O Kidds warper wa3 a flat drive belt, about 1\J> wide, near the floor. They plan to guard the pinch point at the lower pulley with a sheet metal extension of the present sheet metal box or by similar means. 3o 2 8. On loom #17 > termed a cut-down loom, there were two adjacent roller chain drives. They plan to guard these. An enclosure resting on the floor and secured to the machine or floor could be used. Thi3 could be a box-like structure. Possible materials include sheet metal, wire mesh, expanded metal, and rigid plastic shedt. 9. There was no V-belt drive seen on the Iwer Rapier loom. It has a roller chain drive for which they plan to provide a guard. 10. The circular knitter was driven only by a hand wheel, actuated by the operator, presenting no apparent hazard. 11. Items 11 - 13 were located in Building 70. On the large braiding machines, is was suggested that a guard made from a flat sheet of rigid transparent plastic be provided to guard the operator from the rotating spool magazine. 12 On the inside portion of the present V-belt guards of the same machines, it was suggested that additional sheet metal be added to provide guarding at the pinch points. 13. Cn the small braider, it v/as suggested that a transparent plastic buard of box configuration be profided to enclose the upper spur gears. lii. With provision of the guards listed above, exemption is not needed, with the one possible exception of the Tektronix oscilloscope mentioned in Item 3 above. Respectfully submitted. Robert W.
