Text For Citation: 01 Item/Group: 002 Hazard:

29 CFR 1910.147(d): Application of control. The established procedures for the application of energy control (the lockout or tagout procedures) shall cover the following elements and actions and shall be done in the following sequence as required by 29 CFR 1910.147(d)(1) through (d)(6): a. The employer did not ensure that employees implemented energy control procedures prior to engaging in servicing and maintenance activities on equipment such as, but not limited to resistance welding machines, wire cutting machines, wire drawing machines, cold forming machines, wire bending machines, and wire mesh manufacturing machines. On or about February 24, 2017, an employee operating the Ideal 11 resistance welder machine entered the point of operation to unjam and retrieve a wire mesh panel. The machine was not isolated from energy sources prior to engaging in this servicing and maintenance activity. An unexpected release of stored pneumatic energy occurred resulting in the operators left thumb being caught between the mesh panel and weld head coppers. As a result, the remaining applicable energy control elements, involving machine isolation [1910.147(d)(3)], lock-out/tag-out device application [1910.147(d)(4)], dissipation of residual energy [1910.147(d)(5)(i)], and verification of isolation [1910.147(d)(6)], were not implemented to protect employees from machine servicing hazards such as removing jams from the point of operation.
