Well Stimulation Hydraulic Fracturing Safety Inspection Checklist [FREE PDF]

Hydraulic fracturing operations involve high-pressure pumping systems, hazardous chemical additives, and complex wellhead configurations that create significant process safety risks governed by OSHA 29 CFR 1910.119 and API RP 14C. Operators and service companies must systematically verify equipment integrity, chemical handling compliance, and emergency response readiness before and during each frac stage. This checklist provides a structured inspection framework aligned with federal and industry

Industry: Oil & Gas
Frequency: Per Event
Estimated Time: 60-90 minutes
Role: Drilling Supervisor
Total Items: 39
Compliance: OSHA 29 CFR 1910.119 Process Safety Management of Highly Hazardous Chemicals, API RP 14C Recommended Practice for Analysis, Design, Installation and Testing of Safety Systems, BSEE 30 CFR 250 Subpart D Well Operations and Equipment, EPA 40 CFR 112 Spill Prevention Control and Countermeasure (SPCC), NFPA 30 Flammable and Combustible Liquids Code

Pre-Job Documentation and Permits

Confirm all required permits, well program documents, and regulatory notifications are complete and in place before operations begin.

Is the approved well stimulation work program and frac design document available on site and reviewed by the drilling supervisor?
Has the pre-job safety meeting (toolbox talk) been conducted with all personnel and attendance documented?
Is a valid hot work or safe work permit in place for all ignition-source activities in the frac equipment area?
Have regulatory notifications (state oil and gas commission, EPA) been submitted for the stimulation operation as required?
Has the SPCC plan been reviewed and secondary containment verified as adequate for frac chemical volumes on site?

Wellhead and Pressure Control Equipment

Inspect frac tree, wellhead connections, pressure relief devices, and all high-pressure fluid handling equipment for integrity and compliance.

Has the frac tree and wellhead equipment been pressure tested to the maximum anticipated treating pressure plus a safety factor per the well program?
Are all pressure relief valves (PRVs) installed, calibrated, and set to the correct relief pressure for each high-pressure component?
Is high-pressure iron (treating lines) of the correct pressure rating, visually inspected, and free of dents, corrosion, or weld repairs?
Are all hammer unions, wing valves, and swivel joints of the correct API pressure rating and installed with appropriate thread engagement?
Is a functioning kill line and bleed-off valve accessible and operational at the wellhead for emergency pressure release?
Record the maximum allowable treating pressure (MATP) specified in the well program.

Frac Pump and Support Equipment Inspection

Verify pumping units, blenders, sand handling equipment, and associated power systems are in safe operating condition.

Have all frac pump units been inspected for fluid leaks, mechanical integrity, and proper guarding of rotating components prior to job start?
Are pump unit hydraulic systems, high-pressure fluid ends, and packing assemblies free of active leaks or abnormal wear?
Is the blender unit hopper area guarded and proppant handling equipment (augers, conveyors) properly enclosed to prevent personnel contact?
Are combustion exhaust systems on diesel-powered pump units directed away from personnel work areas and chemical storage?
Has the data van / monitoring system been verified to display real-time treating pressure, rate, and wellhead pressure with functional high-pressure alarms?

Chemical Handling, Storage, and Spill Prevention

Inspect frac fluid chemical storage, SDS availability, containment systems, and spill response readiness in compliance with EPA SPCC and OSHA HazCom requirements.

Are Safety Data Sheets (SDS) for all frac chemicals on site accessible to all personnel at the job location?
Are frac chemical totes, tanks, and transfer lines placed within secondary containment sized to hold 110% of the largest single container volume?
Are all chemical container labels intact, legible, and consistent with SDS identity for each product on site?
Is spill response equipment (absorbents, spill kits, emergency response materials) staged and accessible within the chemical handling area?
Have flowback water storage tanks been inspected for integrity and are they within approved storage capacity limits under the SPCC plan?
Record the total volume of frac chemicals (in gallons) stored on site at time of inspection.

Crystalline Silica and Proppant Dust Control

Verify engineering controls, air monitoring, and PPE programs for respirable crystalline silica exposure from proppant handling during fracturing operations.

Are engineering controls (local exhaust ventilation, enclosed conveyor systems, or wet suppression) in place at proppant transfer and blender hopper areas?
Is real-time silica air monitoring being conducted at the breathing zone level for workers in proppant handling areas?
Are N95 or higher-rated respirators available and worn by all personnel in proppant dust exposure zones when engineering controls alone are insufficient?
Are proppant storage super-sacks or boxes staged to minimize manual handling and dust generation during loading operations?
Is a written exposure control plan for respirable crystalline silica available on site and acknowledged by the crew supervisor?

Emergency Response and Pressure Control Readiness

Confirm emergency shutdown systems, pressure kill procedures, and first response capabilities are in place before pumping operations commence.

Is an emergency shutdown (ESD) procedure posted in the data van with clearly assigned roles for pump shutdown, wellhead isolation, and personnel evacuation?
Do all pump operators and the data van engineer have clear communication (radio or hardline) verified functional prior to pumping?
Is a designated safety observer stationed with clear line-of-sight to all high-pressure iron and wellhead connections throughout pumping operations?
Are first aid kit, AED, and emergency eyewash/shower station accessible and within 10 seconds travel from the chemical handling area?
Has the well control kill weight fluid volume and density been calculated, staged, and verified available on site prior to pumping?
Record the kill fluid density staged on location.

Post-Job Inspection and Environmental Closeout

Verify safe depressurization, equipment removal, spill survey, and documentation completion following frac stage completion.

Has all surface treating pressure been bled off to zero and confirmed before disconnecting any high-pressure iron connections?
Has a post-job site walkdown been completed to identify spills, chemical releases, or equipment damage?
Were any chemical spills or releases to soil or water identified during or after the frac operation?
Has all frac chemical waste (empty containers, contaminated materials) been staged for disposal in accordance with the site waste management plan?
Has the completed inspection report been submitted to both the operator drilling supervisor and service company HSE representative?
Attach post-job inspection photographs showing wellhead condition, containment area, and equipment staging area.
