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

29 CFR OSH ACT of 1970 Section (5)(a)(1): The employer did not furnish employment and a place of employment which was free from recognized hazards that were causing or likely to cause death or serious physical harm to employees performing hoisting operations with a foundation drilling rig, thereby exposing employees to struck-by hazards while using an auxiliary winch as a lifting mechanism for hoisting large diameter steel pipes: (a) Jobsite located at 3149-3169 Convention Ave, Philadelphia PA on or about July 6, 2021: The employer failed to protect employees against struck-by hazards in that a Mait HR260 drilling rig, serial number HR2605EF0024, exceeded its capacity in the configuration used while moving a large diameter steel pipe from the deck of a flatbed trailer to ground level. (b) Jobsite located at 3149-3169 Convention Ave, Philadelphia PA on or about July 2, 2021: The employer failed to protect employees against struck-by hazards in that a Mait HR260 drilling rig, serial number HR2605EF0024, was not placed in the required configuration while performing hoisting operations. The machine's drilling tool, articulation and mast base were not in the correct operating condition during use of the auxiliary winch, subjecting the machine to a loss of rig stability and potential overturning moment in the direction of the suspended load. (c) Jobsite located at 3149-3169 Convention Ave, Philadelphia PA on or about July 1, 2021: The employer failed to protect employees against struck-by hazards in that a Mait HR260 drilling rig, serial number HR2605EF0024, was not placed in the required configuration while performing hoisting operations. The machine's drilling tool and mast base were not in the correct operating condition during use of the auxiliary winch, subjecting the machine to a loss of rig stability and potential overturning moment in the direction of the suspended load. Among other methods, feasible and acceptable means of hazard abatement include following the national consensus standard requirements of the American National Standards Institute (ANSI) A10.23-2019 for Safety Requirements for the Installation of Drilled Shafts: Section 6.3: The drilled shaft contractor shall establish a restricted access zone around the drilling and/or hoisting areas to prevent access by persons not directly involved in such operations. The restricted access zone shall be supervised by a drilled shaft contractor designated competent person. Section 9.1: 'The drilled shaft contractor shall comply with the manufacturer's specifications and limitations applicable to the operation of drill rigs, cranes, forklifts, front-end loaders, boom trucks and other mechanized equipment used to install drilled shafts or handle material.' Section 9.2: Only rigging and equipment of adequate capacity and configuration shall be used to handle material. Section 10.2: 'All power equipment shall be operated in accordance with its manufacturer's specifications and safety requirements for use.' Section 12.1: 'The drilled shaft installation equipment manufacturer's recommendations for assembly, disassembly, inspection, maintenance, stability and operation shall be followed. The equipment operator must be familiar with the equipment's configuration and its safe operating procedures and limitations per the manufacturer's specifications. Modifications to such equipment shall be subject to the equipment manufacturer's approval.' Section 12.11: 'The use of an auxiliary winch on drilled shaft installation equipment shall be within the limits established by the equipment manufacturer.' Section 12.11.1: 'A hoist or lift plan should be completed by the drilled shaft contractor prior to hoisting loads with the auxiliary winch.' Among other methods, feasible and acceptable means of hazard abatement include following the manufacturer's instructions in the "MAIT HR260 Manuale Dell'Operatore E Della Sicurezza Operator's and Safety Manual": Page 1.54: 'Do not use the machine beyond its capacity. Do not exceed the nominal values of speed, force, torque, pressure and delivery indicated by the manufacturer.' Page 3.28: 'WARNING! The winches supplied with the rig must be used exclusively for drilling. It is absolutely forbidden to use the winches as cranes or lifting mechanisms.' Page 4.40: 'WARNING! To carry out the rotation of the apparatus, the mast must be in a vertical position, the crawler track must be widened and the counterweight assembled. It is absolutely forbidden to carry out this operation in different conditions. You risk the turnover of the drill rig.'
