Coordinate workforce safety, pipeline-related findings, station inspections, and corrective actions across geographically dispersed assets.
Midstream operations move gas and liquids through gathering systems, transmission pipelines, compressor stations, pump stations, and associated facilities. Maintenance frequently takes place on equipment connected to operating systems, with field crews and control-room personnel sharing responsibility for the work sequence.
Dexur EHS organizes incidents, inspections, exposure concerns, and follow-up by pipeline segment, station, equipment, and activity. Give operations managers, integrity teams, maintenance supervisors, and EHS leaders visibility into unresolved conditions before excavation, line opening, pigging, or equipment restart.

A pipeline maintenance task can depend on conditions beyond the immediate worksite.
Isolation may involve remotely operated valves. Pressure can remain trapped between components. A control-room instruction may affect personnel working at a distant station. Excavation can expose a pipeline whose location or condition differs from available records.
Safety reviews must account for the asset configuration, transported product, operating status, and communication between teams.
Record the affected segment, station, equipment tag, product, and operating state.
A valve discrepancy may require confirmation of the isolation boundary before maintenance proceeds. A receiver-opening concern may require technical review of pressure verification and the work method. A washout may require assessment of pipeline support and safe access.
Dexur EHS preserves the relationship between the observation, operational restriction, assigned response, and verification evidence.
One unified platform
Capture personnel injuries, equipment events, pressure releases, excavation damage, gas alarms, and near misses.
Distinguish the workforce-safety outcome from the pipeline-operating consequence. A release without injury may still require a substantial investigation and a separate regulatory reporting assessment.
Midstream examples include:
Organize inspections around equipment, work scope, and local conditions.
Review:
Associate each finding with a recognizable asset reference, such as a station name, valve number, segment identifier, or milepost.
Bring together the documentation needed to support the assigned work:
Keep the distinction between completing training, demonstrating qualification for a covered task, and receiving authorization for a specific job.
Assign deficiencies to the appropriate operations, maintenance, integrity, engineering, or EHS owner.
Examples include:
Finding → Immediate Safeguard → Technical Assessment → Assigned Work → Verification → Return-to-Service Decision
Retain interim precautions while permanent repairs remain open. Administrative closure should reflect the required technical review rather than simply the completion of a work order.
Relevant categories include:
Record actual consequences and potential severity separately. A discrepancy identified before line opening can provide important information even when no release occurs.
Include:
Preserve timestamps so investigators can reconstruct the relationship between field activity and operating instructions.

Dexur EHS links investigation findings to the specific records, procedures, and equipment requiring attention.
Midstream compliance depends on the facility, product, activity, and jurisdiction.
PHMSA requirements address regulated pipeline transportation. OSHA applicability involves occupational working conditions and can be affected where another federal agency exercises authority over the same conditions. Neither framework should be treated as a blanket replacement for the other. OSHA: Pipeline Jurisdiction Interpretation

Gas gathering requirements differ by regulatory category. PHMSA identifies separate requirements for gathering-line types, including reporting obligations and safety provisions that vary with classification.
Do not assume that all gathering pipelines are unregulated or that every gathering segment must follow the same requirements as a transmission line. Preserve the classification and its supporting basis in the relevant compliance record. PHMSA: Gas Gathering Regulatory Overview
Under the applicable OQ rules, the operator establishes its covered-task list and qualification program.
A general course-completion certificate does not establish qualification for every task. Confirm the individual’s status against the operator’s requirements and the work assigned, including recognition and reaction to abnormal operating conditions. PHMSA: Operator Qualification Overview
For covered operations, control-room management requirements address defined program elements such as roles, procedures, alarm management, fatigue mitigation, and training.
Field investigations should retain relevant communications, equipment status, and the timing of instructions. An EHS action record can support follow-up without replacing the control-room system or its required operational records. PHMSA: Control Room Management
An event may require an OSHA recordability assessment, a pipeline incident or accident reporting determination, or both.
Use the criteria, deadlines, and responsible reviewers applicable to each obligation. A finding that an injury is not OSHA-recordable does not resolve whether a pipeline event is reportable.
| Record | Primary purpose | EHS relationship |
|---|---|---|
| Inline inspection assessment | Identify and evaluate relevant pipeline conditions. | Link field hazards and assigned safety follow-up to the technical finding. |
| Corrosion-control records | Support applicable corrosion-management requirements. | Track related deficiencies without replacing the technical program. |
| Pressure-test documentation | Establish evidence associated with the test and applicable requirements. | Preserve personnel-safety observations and corrective actions. |
| Operator qualification record | Demonstrate qualification under the operator’s covered-task program. | Support task readiness alongside site-specific preparation. |
| Work authorization or permit | Establish the conditions and approvals for a particular activity. | Retain restrictions, hazards, and required checks. |
| Incident investigation | Explain the event and identify preventive measures. | Coordinate actions across operations, engineering, integrity, and EHS. |
Examples include:
A maintenance crew may be ready while an isolation question remains open. An integrity excavation may reveal a condition requiring engineering review before the planned repair. A station restart may depend on restoring safeguards removed during the outage.
Review findings against the next operating step and the people who could be exposed.
Consider the transported material, stored energy, personnel position, equipment condition, and the potential consequences of a failure.
Separate the urgency of workforce protection from technical remediation priorities while keeping both visible to the responsible teams.

| KPI | What to measure | Midstream & Pipelines application |
|---|---|---|
| OSHA TRIR and DART Rate | Recordable cases and cases involving days away, restricted work, or job transfer, normalized by hours worked. | Compare station, pipeline-maintenance, and construction activities using consistent reporting boundaries. |
| Isolation and Line-Opening Events | Discrepancies, unexpected pressure, and related near misses. | Identify weaknesses in identification, procedures, verification, or equipment performance. |
| Pigging Safety Findings | Launcher and receiver defects, opening-related concerns, and unresolved actions. | Review readiness before recurring pigging activities. |
| Excavation and Damage-Prevention Events | Contacts, near misses, and location discrepancies. | Examine the relationship between available records, field verification, and actual excavation conditions. |
| Covered-Task Qualification Readiness | Assigned personnel meeting applicable OQ requirements before work. | Identify task-specific gaps rather than relying solely on training attendance. |
| Critical Inspection and Follow-Up Status | Required checks completed and significant deficiencies resolved. | Monitor station equipment, protective arrangements, and planned-work prerequisites. |
| Verified Corrective Action Closure | Timeliness, technical verification, overdue restrictions, and recurrence. | Determine whether the original condition was resolved before equipment reuse or restart. |
Where reliable activity data exist, review event rates against pig runs, line openings, excavations, or other relevant tasks.
Compare systems and regions while retaining differences in product, activity, and jurisdiction.

Follow-through
This hierarchy allows leadership to move from network-level trends to the exact location and activity requiring attention.
Pipeline safety work crosses geographic and organizational boundaries. A field observation may require action from maintenance, engineering, integrity, operations, or the control room.
Dexur EHS keeps the safety finding and its follow-up traceable as responsibility moves between those teams.
Associate records with segment numbers, station names, equipment tags, and location references that field and office teams recognize.
Retain the communications and equipment conditions needed to understand an event or work restriction.
Review covered-task qualification alongside the local hazards, procedure, equipment status, and authorization required for the assignment.
Separate occupational safety, pipeline reporting, technical assurance, and jurisdiction-specific obligations while coordinating related actions.
Show which unresolved findings affect line opening, maintenance, pigging, or return to service.
Use inspection results, repair documentation, engineering review, or other suitable verification to support closure.
Review whether a closure defect, valve-labeling discrepancy, or communication failure could recur at other stations or pipeline locations.
Bring station inspections, pipeline-work observations, qualification-related findings, incident investigations, and corrective actions into one safety record.
