Text For Citation: 01 Item/Group: 001B Hazard:

OSH ACT of 1970 Section (5)(a)(1):The employer did not furnish employment and a place of employment which were free from recognized hazards that were causing or likely to cause death or serious physical harm to employees exposed to crushing hazards while using under-the-hook lifting devices not designed to meet criteria associated with ASME BTH-1 and ASME B30.20: (a)TM Industries, LLC at 24211 412th Avenue, Artesian, SD 57314: On or about and at times prior to April 4, 2024, the employer did not ensure the square lifting assembly used to set roofs on the walls of recreational vehicle trailer frames was designed by or under the direct supervision of a qualified person. The design shall be in accordance with ASME BTH-1 and shall consider the stresses resulting from the application of rated load plus the weight of the device to minimum design factor of three. The rigging system incorporated two overhead under-hung hoists in order to lift the roofs. One of the nylon straps used to hook to the roof assembly was frayed. The condition exposed employees using the rigging equipment to crushing hazards as a result of the lifting device failing. (b)TM Industries, LLC at 24211 412th Avenue, Artesian, SD 57314: On or about and at times prior to April 4, 2024, the employer did not ensure two swivel assemblies used to lift and rotate trailer frames were designed by or under the direct supervision of a qualified person. The design shall be in accordance with ASME BTH-1 and shall consider the stresses resulting from the application of rated load plus the weight of the device to include a safety factor. The two steel swivels used to lift the frames were attached to the hooks of two overhead under-hung hoists. The swivel lifting apparatuses allowed employees to rotate the frames of the recreational vehicles. The condition exposed employees using the swivels to crushing hazards as a result of the lifting device failing. (c)TM Industries, LLC at 24211 412th Avenue, Artesian, SD 57314: On or about and at times prior to April 4, 2024, the employer did not ensure the swivel assembly used to rotate trailer frames and the square roof lifting assembly used to place roofs on the recreational vehicles, were rated prior to initial use. Both under-the-hook lifting assemblies did not have the rated load capacity marked or identification affixed listing the manufacturer's name, address, serial number and lifting device weight. The condition exposed employees to crushing hazards as a result of the lifting device failing. Among other methods, one feasible and acceptable abatement method can be found in the American Society of Mechanical Engineers, ASME B30.20-1.2.2 Construction, "Structural and mechanical lifting devices shall be designed to ASME BTH-1 Design Category B (static strength criteria) selected for its number of load cycles, unless a qualified person representing the owner, purchaser, or user of the lifting device determines and can demonstrate that ASME BTH-1 Design Category A is appropriate. Design Category A shall only be designated when the magnitude and variation of loads applied to the lifter are predictable and do not exceed the rated capacity, where the loading and environmental conditions are accurately defined, service is not severe, and the anticipated load cycles do not exceed Service Class 0. Among other methods, one feasible and acceptable abatement method can be found in the American Society of Mechanical Engineers, ASME B30.20 Below-The-Hook Lifting Devices, section 20-1.2.1 Marking, Rated Load-All new structural and mechanical lifting devices shall be marked with, but not limited to, the following information: (1) manufacturer's name and address (2) serial number (3) lifter weight, if over 100 lbs. (4) rated voltage (when applicable) (5) rated load (6) ASME BTH-1 Design Category (7) ASME BTH-1 Service Class
