PART 85. THE CONTROL OF HAZARDOUS ENERGY SOURCES  
R 408.18501 Scope.  
Rule 8501. (1) These rules establish minimum requirements for the  
lockout/tagout of energy sources for the protection of employees, in, on, or around  
machines, equipment, or a process during repair, maintenance, and associated  
activities, from injury due to unexpected/unintended motion, energization, start-up, or  
release of stored energy from the machine, equipment, or process.  
(2) Except where the provisions of these rules conflict with specific requirements  
for the lockout/tagout of energy sources in any other general industry safety standard,  
the provisions of these rules and the requirements specified in any other general  
industry safety standard rule shall be deemed to have concurrent application. Where a  
specific general industry safety standard contains lockout/tagout requirements, the  
specific provisions set forth in the general industry safety standard shall prevail if  
there is a conflict with the requirements set forth in these rules.
