Incident on Dec 11, 2018: Employee fractures leg when struck by sledgehammer

At 9:30 a.m. on December 11, 2018, an employee was working as a laborer for a firm that manufactured concrete pipe. He had worked for the firm for about 11.5 years. The firm employed about 900 people, with some 13 employees working at a pipe plant. The incident occurred in a pit at the plant. The employee was using a 4 pound (1.8 kg) sledgehammer to clean concrete residue from around a broken bolt in a Turmac core base in preparation of replacing the bolt. His supervisor had instructed him to prepare the area around the bolt while the supervisor went to get a replacement bolt. The core base was at knee height. Although the supervisor considered that it would be safer working on the bolt with it at waist height, raising the equipment would have required undoing the lockout/tagout of the system. Thus the supervisor decided to leave the Turmac core base at the level it was at when the bolt was found. The employee had a choice of tools for removing the concrete residue, including the sledgehammer, a pneumatic needling gun, and a pneumatic chisel. The employee used an overstrike with the sledgehammer. The sledgehammer glanced off the concrete material on the core base and struck the employee's left shin. He suffered a fracture to his lower left leg. He was transported to a hospital. He was hospitalized for more than 24 hours. The incident occurred after the employer had launched an initiative to remove all unnecessary sledgehammers from its manufacturing facilities to reduce the injury rate. The employer had issued a directive that there was no need to use a sledgehammer in the pit, and that the use of a sledgehammer there required the plant manager's approval. The plant manager had conducted a survey to identify and remove unnecessary sledgehammers from the plant. The manager had not approved the use of a sledgehammer in the pit. The supervisor was aware of the survey and directive but chose not to turn in the pit sledgehammer, thinking it should stay for some tasks.

Incident on Jul 26, 1994: Employee's fingers partially amputated by machine shaft

Employees of the Hydro Conduit Corp. were attempting to dislodge the inner shaft on a drain pipe forming machine to replace a shaft bearing.

His fingers, which were under the shaft, struck against a 6 in. by 6 in. wood block held up by two steel saw horses. The tip of his left index finger and right little finger were partially amputated.

The rules behind these citations

Current text from the Code of Federal Regulations. Some citations were issued under older wording.

29 CFR 1910.212 · Machine guarding

29 CFR 1910.212(a)(1)

(a) Machine guarding—(1) Types of guarding. One or more methods of machine guarding shall be provided to protect the operator and other employees in the machine area from hazards such as those created by point of operation, ingoing nip points, rotating parts, flying chips and sparks. Examples of guarding methods are—barrier guards, two-hand tripping devices, electronic safety devices, etc.

29 CFR 1910.215 · Grinders and abrasive wheels

29 CFR 1910.215(a)(4)

(4) Work rests. On offhand grinding machines, work rests shall be used to support the work. They shall be of rigid construction and designed to be adjustable to compensate for wheel wear. Work rests shall be kept adjusted closely to the wheel with a maximum opening of one-eighth inch to prevent the work from being jammed between the wheel and the rest, which may cause wheel breakage. The work rest shall be securely clamped after each adjustment. The adjustment shall not be made with the wheel in motion.

29 CFR 1910.215(b)(9)

(9) Exposure adjustment. Safety guards of the types described in subparagraphs (3) and (4) of this paragraph, where the operator stands in front of the opening, shall be constructed so that the peripheral protecting member can be adjusted to the constantly decreasing diameter of the wheel. The maximum angular exposure above the horizontal plane of the wheel spindle as specified in paragraphs (b) (3) and (4) of this section shall never be exceeded, and the distance between the wheel periphery and the adjustable tongue or the end of the peripheral member at the top shall never exceed one-fourth inch. (See Figures O-18, O-19, O-20, O-21, O-22, and O-23.)
