An Oil & Gas Safety Manual provides written occupational safety and health programs, procedures, and responsibilities for companies involved in oil and gas drilling, well servicing, workover, completion, production, and related oilfield operations.
Oil and gas employees may work around drilling rigs, service rigs, wellheads, pressure equipment, tanks, pumps, compressors, mobile equipment, vehicles, chemicals, flammable gases and vapors, hydrogen sulfide, and other potentially serious hazards.
An effective Oilfield Safety Manual should address the company’s actual operations, equipment, employee duties, chemicals, work locations, contractor relationships, and occupational exposures rather than relying on a generic industrial safety program.
Depending on operations, applicable programs may address vehicle safety, struck-by and caught-between hazards, fire and explosion prevention, hydrogen sulfide, high-pressure equipment, hazardous energy, machine guarding, confined spaces, fall protection, chemical exposure, silica, noise, respiratory protection, heat stress, fatigue, emergency response, and other oilfield hazards.
The contents of an Oil & Gas Safety Manual should reflect the work actually performed.
Depending on company operations, the manual may address:
Programs should be selected according to actual oilfield operations and employee exposures.
An effective Oil & Gas Safety Program establishes responsibilities and procedures for identifying hazards, controlling employee exposures, preventing injuries and illnesses, and coordinating work at drilling, servicing, production, and other oilfield locations.
Management should provide the equipment, engineering controls, PPE, training, supervision, communication systems, and other resources necessary for employees to perform assigned work safely.
Managers, supervisors, and designated safety personnel should:
Employees should follow established procedures, participate in JSAs and pre-job planning, inspect equipment, use required PPE, and promptly report unsafe conditions, equipment defects, injuries, exposures, spills, releases, and other hazards.
Oil and gas worksites frequently involve multiple employers performing specialized operations at the same location.
Before work begins, employers should determine:
Employees should receive information necessary to understand hazards created by other operations that may affect their work.
Job Safety Analysis is particularly important in oil and gas operations because hazards can change according to the activity, equipment, well condition, weather, contractors, and simultaneous operations.
A JSA/JHA should identify:
Employees performing the work should participate in the JSA process when appropriate.
Before higher-risk or non-routine operations begin, affected employees should review:
The plan should be revised when conditions change significantly.
Employees should understand their authority and responsibility to stop or suspend work when they identify an imminent danger, uncontrolled hazard, unexpected condition, or significant deviation from the work plan.
Work should not resume until the condition has been evaluated and appropriate controls have been established.
Employees should not be discouraged from exercising legitimate stop-work authority.
Inspections should reflect the equipment and activities present at the worksite.
Potential inspection areas include:

Manual tank gauging, sampling, or opening tank hatches can expose employees to concentrated hydrocarbon gases and vapors.
Where these tasks are performed, procedures should address:
Employees should avoid placing their head or upper body directly over an open hatch.
Operations involving movement of flammable liquids, gases, or materials may generate static electricity.
Bonding, grounding, equipment selection, and work practices should be used where required to control ignition hazards.
Welding, cutting, brazing, grinding, and other spark- or flame-producing work should be controlled around oil and gas operations.
Before hot work begins, employees should evaluate:

Oil and gas wells and production operations can release hydrogen sulfide.
H2S can present severe health hazards and may rapidly create life-threatening conditions.
The company’s H2S procedures should reflect the potential exposure at its worksites.
Before work begins in locations where H2S may be present, employers should evaluate:

Depending on operations, training may address:
Task-specific training should be provided before employees independently perform higher-hazard work.
Companies using a Short Service Employee program may identify employees who are new to the company, industry, position, or task and require additional supervision or mentoring.
The program may address:
Contractor safety is particularly important where multiple companies perform simultaneous operations.
Coordination should address:

A useful Oil & Gas Safety Manual should reflect the company’s actual position within the oil and gas industry.
A drilling contractor may require extensive procedures for rigging up, drilling, tripping pipe, casing, well control, derricks, and rig-floor operations.
A well-servicing company may place greater emphasis on workover rigs, rods, tubing, pressure equipment, pumping units, and specialized services.
A hydraulic-fracturing contractor may require extensive controls for silica, pressure pumping, chemical handling, mobile equipment, flowback, and simultaneous operations.
A production company may focus more heavily on wellheads, tanks, production equipment, H2S, hydrocarbon gases and vapors, gauging, sampling, maintenance, and contractor coordination.
The applicable programs should therefore be selected according to the work actually performed rather than automatically assigning every oilfield program to every company.
An Oil & Gas Safety Manual can be developed around the company’s drilling, well servicing, completion, production, hydraulic fracturing, equipment, chemicals, vehicles, contractors, client requirements, and other occupational hazards.
The finished manual may incorporate applicable programs for H2S, High-Pressure Systems, Fire Prevention, Lockout/Tagout, Confined Space, Fall Protection, Rigging, Mobile Equipment, Hazard Communication, Respiratory Protection, Silica, PPE, Heat Stress, Fatigue Management, Emergency Response, Contractor Safety, JSA/JHA, and other hazards present within the operation.
This provides drilling contractors, well-service companies, oilfield service companies, producers, and other oil and gas employers with a practical safety manual organized around the work their employees actually perform.
