(2) through (4) of this appendix except that the burden of proof shall be on OSHA to demonstrate by a preponderance of the evidence that the recognition should be revoked because the validation organization either is not meeting the requirements for recognition, has not been performing the validation functions required by the PSDI standard and appendix A, or has misrepresented itself in its applications. Pulleys shall be kept in proper alignment to prevent belts from running off. [39 FR 23502, June 27, 1974, as amended at 43 FR 49750, Oct. 24, 1978; 43 FR 51760; Nov. 7, 1978; 49 FR 5323, Feb. 10, 1984; 61 FR 9227, March 7, 1996; 69 FR 31882, June 8, 2004], Occupational Safety & Health Administration. (D) The requirements for hand tools that may be used in the PSDI mode. 3 Slenderness ratio formula for short columns is L/d = 11, where L = length of timber in inches and d = least dimension in inches; this ratio should not exceed 11. 1910.133 Eye and face protection. Nor would it be necessary to repeat these tests in the case of modifications where determined by the manufacturer and validated by the third-party validation organization to be equivalent by similarity analysis. (d) Two hand trips shall be fixed in position so that only a supervisor or safety engineer is capable of relocating the controls. A controlled clearance between the wheel hole and the machine spindle (or wheel sleeves or adaptors) is essential to avoid excessive pressure from mounting and spindle expansion. The validation organization shall have a reasonable written procedure for acknowledging and processing appeals or complaints from program participants (manufacturers, producers, suppliers, vendors and employers) as well as other interested parties (employees or their representatives, safety personnel, government agencies, etc. (29) Manual feeding means feeding wherein the material or part being processed is handled by the operator on each stroke of the press. This type, however, differs from Type 5 in that the grinding is performed on the wall of the abrasive created by the difference between the diameter of the recess and the outside diameter of the wheel. (3) Each disk sanding machine shall have the exhaust hood, or other guard if no exhaust system is required, so arranged as to enclose the revolving disk, except for that portion of the disk above the table, if a table is used, which may be necessary for the application of the material to be finished.

A validation organization may not terminate its installation certification and recertification validation functions earlier than either one year from the date of the written notice, or the date on which another recognized validation organization is able to perform the validation of installation certification and recertification. If such a guard is constructed of sheet metal, the material used shall be not less than one-sixteenth inch in thickness; and if cast iron is used, it shall not be less than three-sixteenths inch in thickness. means the distance in feet any one abrasive grain on the peripheral surface of a grinding wheel travels in 1 minute. (vi) The presence sensing device location shall either be set at each tool change and set-up to provide at least the minimum safety distance, or fixed in location to provide a safety distance greater than or equal to the minimum safety distance for all tooling set-ups which are to be used on that press. This web site is designed for the current versions of Overhead chain and link belt drives are governed by the same rules as overhead horizontal belts and shall be guarded in the same manner as belts. The visual check shall include a determination that the spring housing or rod does not show damage sufficient to degrade the structural integrity of the unit, and the spring does not show any tendency to interleave. (3) Guarding vertical and inclined shafting.

It is recommended that old installations be changed to conform to this rule. (18) Die means the tooling used in a press for cutting or forming material. However,current OSHA regulations on the control of hazardous energy sources (lockout/tagout)[29 CFR 1910.147],and machine guarding [29 CFR Part 1910.212 ] are applicable to these types of equipment. General. 1910.268 Telecommunications. Where guard is exposed to contact with moving equipment, additional strength may be necessary.
