What this inspection record means

OSHA opens inspections for many reasons — routine scheduling under a national or local emphasis program, an employee complaint or referral, or a follow-up after a reported injury. Opening or conducting an inspection is not itself an allegation or a finding that this employer broke any rule; any findings appear as the citations listed below, and citations can be contested, reduced, or withdrawn.

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 in that employees were exposed to struck-by, fire, and explosion hazards associated with the unmanaged release of gas and pressure from an oil and gas well during plugging activities.   a. Located at API 34167665780000, Matamoras, Ohio 45767: On or about August 25, 2025, the employer was attempting to plug an orphan oil and gas well. The employer did not effectively manage and control the release of gas and pressure during plugging operations and thereby exposed employees to struck-by, fire, and explosion hazards. The employer attempted to plug the well with cement without maintaining continuous well control. Ignition sources were located in proximity to the well and had not been positioned based on an assessment of their distance from released gases and fumes. The employer did not monitor the release of gases and fumes during the operation. Each of these conditions increased the likelihood that a fire and/or explosion would occur.
