OSHA has cited Horizontal Well Drillers with three repeat and one serious safety violation for exposing workers to hazards at a drilling site in Jacksboro. The agency's Fort Worth Area Office opened an inspection on May 10 in response to a complaint alleging unsafe working conditions. Proposed penalties total $71,500.

The repeat violations include failing to provide an auxiliary escape line, ensure all guardrails are installed to prevent falls of more than 4 feet and ensure the usage of personal protective equipment such as flame-resistant clothing in the event of a flash fire.

The serious violation involves a failure to ground the shale shaker trailer.

Horizontal Well Drillers, headquartered in Purcell, Okla., is an oil and gas drilling company that employs about 450 workers. The company has 15 business days from receipt of its citations to comply, request an informal conference with OSHA's Fort Worth area director or contest the citations and proposed penalties before the independent Occupational Safety and Health Review Commission.
