After successfully completing the assigned requirements of the program, participants should be able to:

1. Recognize Oil and Gas Hazards

   Identify common occupational, operational and process-related hazards associated with oil and gas workplaces.

2. Evaluate Workplace Risk

   Apply fundamental risk-assessment principles to evaluate exposure, potential consequences and existing controls.

3. Support Effective Risk Control

   Use the hierarchy of controls to evaluate and support appropriate preventive measures.

4. Recognize Process-Safety Concerns

   Explain the distinction between occupational and process safety and recognize conditions that may affect containment or critical safeguards.

5. Verify Workplace Controls

   Observe work conditions and evaluate whether assigned precautions and important controls are implemented in practice.

6. Support Incident Prevention and Investigation

   Identify unsafe conditions, report near misses and contribute relevant information to incident investigation and corrective-action processes.

7. Communicate Safety Information

   Communicate hazards, observations and control deficiencies clearly to workers, supervisors and other responsible personnel.

8. Escalate Significant Risk

   Recognize conditions that exceed the specialist’s authority or competence and refer them for appropriate technical, supervisory or management attention.

Safety specialists support the systematic identification and control of workplace risk. Their responsibilities can include inspections, hazard assessments, field observations, safety communication, documentation, incident reporting and verification of assigned precautions.

The specialist role requires both technical awareness and professional judgment. A specialist should be able to recognize when conditions are inconsistent with established requirements and when additional expertise or authority is necessary.

Hazard identification is the foundation of effective risk control. Oil and gas specialists should consider equipment, substances, energy sources, work activities, environmental conditions, personnel and interactions between simultaneous operations.

Hazards should be evaluated during routine and non-routine work, maintenance, startup, shutdown, construction and foreseeable abnormal conditions.

Field conditions can change rapidly, so hazard identification should continue throughout the work rather than being treated as a one-time activity.

Risk assessment considers how harm could occur, who may be exposed, the potential consequences and whether existing controls are adequate.

Risk ratings can help prioritize attention, but the numerical result should not replace professional evaluation of the actual hazard and control effectiveness.

Specialists should recognize situations requiring additional engineering, operational, supervisory or technical evaluation.

A structured process helps translate hazard recognition into practical preventive action.

1. Identify

   Recognize the hazard, exposed personnel and conditions capable of producing harm.

2. Evaluate

   Consider exposure, potential consequences and the effectiveness of existing controls.

3. Control

   Support selection of appropriate measures using the hierarchy of controls.

4. Communicate

   Ensure relevant personnel understand identified hazards and required precautions.

5. Verify

   Observe whether controls have actually been implemented in the workplace.

6. Document

   Record significant findings according to applicable organizational requirements.

7. Escalate

   Refer unresolved or significant risk to appropriate supervisory, management or technical personnel.

The hierarchy of controls helps specialists evaluate risk-reduction measures according to their potential effectiveness.

Elimination and substitution should be considered where feasible. Engineering controls isolate personnel from hazards or contain hazardous substances and energy. Administrative controls influence how work is organized and performed, while PPE provides an additional protective layer.

Higher-risk activities often require multiple complementary controls rather than reliance on a single precaution.

Task hazard analysis provides a systematic method for examining work before it begins.

The activity can be divided into logical steps so hazards and controls can be considered at each stage. Personnel familiar with the actual work should contribute where appropriate.

The assessment should be reviewed when equipment, personnel, location, operating conditions or the scope of work changes.

Oil and gas specialists need awareness of both occupational safety and process-safety risk.

Occupational safety commonly addresses hazards such as falls, electrical contact, equipment injuries and manual handling. Process safety focuses particularly on preventing significant releases of hazardous substances or energy capable of causing fire, explosion or toxic exposure.

Safety specialists should recognize indicators of weakened process safeguards and ensure significant concerns are appropriately communicated.

Some safeguards are particularly important because their failure can significantly increase the potential for a serious event.

Depending on the operation, these can include isolation, gas detection, alarms, shutdown systems, pressure protection, containment, barriers and exclusion zones.

Specialists should understand the importance of field verification and report critical controls that are absent, bypassed, damaged or otherwise ineffective.

Changes to equipment, process conditions, materials, procedures, staffing or work methods can introduce hazards or invalidate existing controls.

Safety specialists should be alert to temporary and permanent changes observed during field activities.

Where a change requires formal review, it should be referred through the applicable management-of-change process rather than accepted without appropriate evaluation.

Permit-to-work systems provide structured control for designated higher-risk and non-routine work.

Permits may address activities such as hot work, confined-space entry, electrical work, excavation and line breaking depending on the operation.

Safety specialists should understand how permits connect work authorization with hazard assessment, isolation, testing, communication and field verification.

Different work groups operating in the same area can introduce hazards through their interactions.

Production, maintenance, construction, lifting, hot work and vehicle activities can affect one another even when each task appears acceptable when evaluated separately.

Specialists should identify conflicting activities and communicate potential interfaces to responsible supervisory or operational personnel.

Drilling environments can involve rotating equipment, tubular handling, suspended loads, pressure, work at height, vehicles and hazardous gases or fluids.

Safety specialists should recognize the importance of exclusion zones, machine safeguards, safe access, housekeeping, communication and appropriate control of lifting and pressure hazards.

Specialized well-control responsibilities require technical competency beyond general occupational safety education.

Production and processing facilities can contain pressurized hydrocarbons, flammable materials, toxic substances, rotating machinery and equipment operating under elevated temperatures or pressures.

Specialists should remain alert to leakage, deterioration, damaged safeguards, abnormal conditions and unauthorized work on process equipment.

Potential integrity or process-safety concerns should be promptly referred through appropriate operational channels.

Hydrogen sulfide can present severe toxic exposure risk in some oil and gas environments.

Depending on the workplace, controls can include detection, alarms, ventilation, restricted access, respiratory protection and emergency arrangements.

Personnel should not rely on odor to determine whether an H2S atmosphere is safe.

Oil and gas operations require effective management of fuel sources, flammable atmospheres and ignition sources.

Controls can include containment, ventilation, suitable electrical and mechanical equipment, ignition-source restrictions, hot-work controls and atmospheric testing where applicable.

Specialists should recognize conditions capable of increasing fire or explosion risk and communicate them promptly.

Welding, cutting, grinding and other heat- or spark-producing activities can create ignition hazards where combustible materials or flammable atmospheres may be present.

Hot-work controls can include authorization, isolation, area preparation, atmospheric testing, fire prevention and monitoring according to workplace requirements.

Conditions should continue to be evaluated while the activity is in progress.

Confined spaces can contain hazardous atmospheres, stored energy, engulfment hazards and restricted access that complicates emergency response.

Controls may include isolation, atmospheric evaluation, authorization, ventilation, communication, attendant arrangements and rescue preparedness as applicable.

Specialized confined-space duties require appropriate role-specific competency and authorization.

Maintenance and servicing activities can expose personnel to electrical, mechanical, hydraulic, pneumatic, thermal, chemical and pressure energy.

Energy sources should be identified, isolated and appropriately controlled before work begins, with verification performed according to applicable procedures.

Safety specialists should recognize incomplete or questionable isolations and refer concerns before affected work proceeds.

Electrical hazards can include shock, burns, arc-related hazards, ignition and unexpected equipment energization.

Safety specialists should recognize unsafe equipment conditions, damaged electrical components, inappropriate temporary installations and work being performed without required controls.

Specialized electrical work should be performed only by personnel with the required competency and authorization.

Piping, vessels, hoses, valves, pumps, compressors and other equipment can expose personnel to pressure, stored energy, moving parts and hazardous substances.

Specialists should recognize leakage, damaged guarding, visible deterioration and other conditions that may indicate inadequate control.

Intrusive work should follow applicable isolation, depressurization and work-authorization requirements.

Cranes, hoists, lifting accessories and suspended loads are common across drilling, production, construction and maintenance operations.

Safety considerations include equipment condition, load characteristics, competent personnel, communication, environmental conditions and exclusion zones.

Complex or higher-risk lifts may require specialized planning and technical review beyond the safety specialist’s authority.

Personnel can be exposed to fall hazards while working on structures, platforms, scaffolds, ladders and elevated equipment.

Safe access and collective fall-prevention measures should be considered before reliance on personal fall-protection systems where feasible.

Where personal systems are required, appropriate equipment, anchorage, inspection, competency and rescue considerations should be addressed.

Scaffolds and temporary access systems require appropriate design, erection, inspection and use according to applicable workplace requirements.

Safety specialists should recognize visible deficiencies such as incomplete platforms, inadequate access, missing edge protection, unstable conditions or unauthorized modification.

Competent-person responsibilities for scaffolding require the qualifications and authority applicable to that role.

Excavation can expose personnel to collapse, underground utilities and pipelines, hazardous atmospheres, water and mobile equipment.

Ground-disturbance activities should be planned and authorized according to applicable site requirements.

Safety specialists should recognize changing excavation conditions and report deficiencies in access, protective systems or work controls.

Transportation risk can arise from vehicle condition, road conditions, fatigue, speed, weather, reversing and interaction between mobile equipment and pedestrians.

Oil and gas operations may also involve remote travel where journey planning and emergency considerations become particularly important.

Safety specialists should support compliance with applicable vehicle, traffic and journey-management controls.

Workers should have appropriate information about hazardous substances used or encountered during their work.

Hazard communication can include labels, Safety Data Sheets, handling precautions, storage requirements, PPE and emergency information.

Safety specialists can support effective communication by confirming that relevant information is accessible and understood by affected personnel.

Oil and gas workers can be exposed to hydrocarbon vapors, gases, chemicals, noise, heat, vibration, dust and ergonomic stressors.

Some exposures cannot be evaluated reliably through visual inspection or subjective judgment alone.

Safety specialists should recognize when industrial hygiene monitoring, occupational health evaluation or other technical expertise may be necessary.

Drilling rigs, compressors, pumps, generators and other industrial equipment can produce significant noise.

Controls may include quieter equipment, engineering measures, exposure management and appropriate hearing protection.

Where exposure levels are uncertain, appropriate measurement and technical evaluation may be required.

Outdoor operations, protective clothing and physically demanding work can increase heat-related risk.

Preventive arrangements can include hydration, acclimatization, work-rest planning, shade or cooling and recognition of heat-related symptoms.

Safety specialists should recognize changing environmental and workload conditions that may increase exposure.

Manual material handling, repetitive work, awkward postures and forceful exertion can contribute to musculoskeletal injury.

Specialists should consider mechanical assistance, work layout, load characteristics, task design and other controls rather than relying only on lifting technique.

PPE provides an important protective layer when hazards cannot otherwise be adequately controlled.

Effective use depends on appropriate selection, compatibility, fitting where applicable, inspection, maintenance and user understanding.

PPE should complement stronger preventive measures rather than automatically replacing feasible engineering or operational controls.

Contractors perform substantial portions of oil and gas construction, maintenance, drilling, transportation and specialist work.

Safety specialists can support contractor coordination by identifying interfaces, communicating site hazards, observing work conditions and reporting control deficiencies.

• Understand contractor and host responsibilities.
• Communicate relevant site hazards.
• Review applicable work controls.
• Observe contractor work conditions.
• Identify conflicting activities.
• Report significant deficiencies.
• Support corrective-action follow-up.

Safety information should be communicated clearly enough for personnel to understand how it affects their work.

Specialists may contribute to orientations, toolbox discussions, hazard briefings, inspection feedback and incident learning.

Effective communication includes listening to workers and confirming understanding rather than simply distributing information.

Inspections provide a structured method for identifying hazards, deteriorating conditions and weaknesses in control implementation.

Effective inspections should consider both visible physical conditions and whether important work controls are functioning in practice.

1. Prepare

   Understand the area, activities and relevant hazards before the inspection.

2. Observe

   Examine workplace conditions, behaviors, equipment and control implementation.

3. Discuss

   Engage relevant personnel to understand actual work conditions and concerns.

4. Record

   Document significant observations accurately.

5. Prioritize

   Distinguish significant risk from lower-priority deficiencies.

6. Follow Up

   Confirm that assigned corrective actions receive appropriate attention.

Oil and gas emergencies can include fire, explosion, toxic release, loss of containment, medical emergencies, severe weather and transportation incidents.

Safety specialists should understand relevant alarms, communications, evacuation or shelter arrangements, assembly points and assigned responsibilities.

Specialized emergency-response functions require the competency, equipment and authorization applicable to those duties.

Incidents, near misses and unsafe conditions provide important information about weaknesses in workplace controls.

Safety specialists should support timely and accurate reporting and recognize when an event requires immediate escalation.

Near misses should be evaluated according to their potential consequences rather than dismissed because no injury occurred.

Incident investigation seeks to understand how an event occurred and why existing controls did not prevent it.

Specialists can contribute by collecting information, documenting workplace conditions, interviewing personnel where assigned and supporting analysis of immediate and contributing factors.

1. Respond

   Address immediate safety needs and stabilize relevant conditions.

2. Preserve

   Protect relevant evidence and information where appropriate.

3. Gather

   Collect observations, records and witness information.

4. Analyze

   Consider immediate, contributing and underlying factors.

5. Correct

   Support actions that address identified causes and control weaknesses.

6. Verify

   Confirm that assigned improvements have been implemented where responsible.

Inspection and investigation findings provide little value when corrective actions are not implemented.

Safety specialists can support follow-up by recording findings, tracking assigned actions and verifying workplace conditions where appropriate.

Unresolved significant risk should be escalated rather than treated as complete solely because an administrative deadline has passed.

Accurate records support communication, accountability, trend analysis and organizational learning.

Depending on assigned responsibilities, specialists may work with inspection records, hazard reports, incident information, training records, corrective actions and other HSE documentation.

Records should accurately represent actual workplace conditions and activities rather than being completed merely to satisfy an administrative requirement.

Human performance can be affected by fatigue, workload, communication, equipment design, procedures, supervision and workplace pressures.

Specialists should consider these conditions when evaluating unsafe behavior or contributing factors rather than assuming individual carelessness is always the primary explanation.

Operational discipline is strengthened when procedures are practical, expectations are understood and personnel can report conditions that differ from the original plan.

Safety specialists should communicate observations accurately, respect the limits of their competence and avoid representing assumptions as verified facts.

Significant hazards, failed controls and conditions outside the specialist’s authority should be communicated to appropriate supervisory, technical or management personnel.

Professional practice requires objective reporting even when findings are inconvenient or require operational changes.

The program provides 155 learning hours integrating occupational safety and health with oil and gas hazard recognition, operational risk, process-safety awareness, field verification and incident prevention.
