Question 3: If the answer is that we must implement a way to effectively lockout for gravity in situations described in question 2, how would you go about accounting for, developing, and training mechanics on such situations that are not routine and sometimes are created during a one-time servicing situation or during assembly or disassembly? Response: The employer shall consider all potential hazards from unexpected startup or release of stored energy, including the gravitational effects on loose equipment parts and take action necessary to eliminate or minimize such hazards. Question 2: Using the scenario in question 1, does changing out loader attachments, where the hazard potential is attachments falling once hydraulic parts are operated, require a lockout procedure? It would also be prudent to follow the pertinent sections of the manufacturer’s service manual when servicing the equipment. Response: Servicing mobile equipment in the manner described above would likely meet the requirements for control of any hazardous energy (including the hazards of servicing split-rim wheels). Question 1: Does servicing mobile equipment, such as front end loaders, with the electrical circuit locked and tagged out, tires blocked, and the lifting arms set on the ground to eliminate gravitational hazards meet the requirements of. 147, apply to lockout and tagout of vehicle-type mobile construction equipment, such as front end loaders, during maintenance. You requested that OSHA provide an interpretation of how the lockout/tagout requirements in.
