  Dear Mr. Funcheon: 
                    This is in further response to your 
                    undated letter that we received on May 24, in which you asked 
                    if the Occupational Safety and Health Administration (OSHA) 
                    requires point of operation guards and/or lockouts to be in 
                    place during the cleanup and sanitizing of machinery and equipment 
                    in the meat packing industry. 
                    The answer to your first question 
                    is yes; OSHA requires that effective safeguards be in place 
                    for the protection of the employees engaged in both the operation, 
                    as well as cleanup and sanitizing, of machinery and equipment 
                    in the meat packing industry. Section 29 CFR 1910.147, the 
                    Control of Hazardous Energy (Lockout/Tagout) standard, covers 
                    the servicing and maintenance of machines and equipment in 
                    which the unexpected energization or start up of the machines 
                    or equipment, or release of stored energy, could cause injury 
                    to employees. Normal production operations are not covered 
                    by this standard unless during the servicing and/or maintenance, 
                    which takes place during normal production operations, the 
                    employee performing the servicing may be subjected to hazards 
                    that are not encountered as part of the production operation 
                    itself. This situation would occur if the employee must either 
                    remove or bypass machine guards or other safety devices, resulting 
                    in exposure to hazards at the point of operation, if the employee 
                    is required to place any part of his or her body in contact 
                    with the point of operation of the operational machine or 
                    piece of equipment, or finally, if the employee is required 
                    to place any part of his or her body into a danger zone associated 
                    with a machine operating cycle. If any of the above mentioned 
                    situations exist, then the provisions of the lockout/tagout 
                    standard would apply. 
                    A note to paragraph (a)(2)(ii)(B) 
                    of the standard does provide a limited exception for minor 
                    servicing activities which take place during normal production 
                    operations, but only if these activities are routine, repetitive, 
                    and integral to the use of the equipment for production, and 
                    provided that the work is performed using alternative measures 
                    which provide effective protection. 
                    In response to your second question, 
                    the participation or degree of support given by Mr. Barry 
                    White in the development of the lockout/tagout standard was 
                    a part of the deliberative process that takes place during 
                    the formulation of all standards. We have no record of and 
                    are unable to characterize at this time the extent or nature 
                    of his support for the standard. 
                    If you should need additional assistance, 
                    please contact us again. 
                    Sincerely, 
                    Patricia K. Clark, DirectorDirectorate of Compliance Programs
