Safety Hazards Associated With Oil And Gas Extraction Activities.docx

Safety Hazards Associated with Oil and Gas Extraction Activities Oil and gas well drilling and servicing activities involve many different types of equipment and materials. Recognizing and controlling hazards is critical to preventing injuries and deaths. Several of these hazards are highlighted below. See Standards and Enforcement for more information on evaluation and control requirements.

Vehicle Collisions Struck-By/ Caught-In/ Caught-Between Explosions and Fires Falls Confined Spaces Ergonomic Hazards High Pressure Lines and Equipment Electrical and Other Hazardous Energy Machine Hazards Planning and Prevention

Vehicle Collisions Workers and equipment are required to be transported to and from well sites. Wells are often located in remote areas, and require traveling long distances to get to the sites. Highway vehicle crashes are the leading cause of oil and gas extraction worker fatalities. Roughly 4 of every 10 workers killed on the job in this industry are killed as a result of a highway vehicle incident (Census of Fatal Occupational Injuries). The following OSHA and NIOSH documents provide guidance on recognizing and controlling vehicle-related hazards:

Struck-By/ Caught-In/ Caught-Between Three of every five on-site fatalities in the oil and gas extraction industry are the result of struck-by/caught -in/caught-between hazards (OSHA IMIS Database). Workers might be exposed to struck-by/caught-in/caught-between hazards from multiple sources, including moving vehicles or equipment, falling equipment, and high-pressure lines.

Explosions and Fires Workers in the oil and gas industries face the risk of fire and explosion due to ignition of flammable vapors or gases. Flammable gases, such as well gases, vapors, and hydrogen sulfide, can be released from wells, trucks, production equipment or surface equipment such as tanks and shale shakers. Ignition sources can include static, electrical energy sources, open flames, lightning, cigarettes, cutting and welding tools, hot surfaces, and frictional heat.

Planning and Prevention For process-specific and task-specific hazards and controls, see OSHA's Oil and Gas Well Drilling and Servicing eTool. The eTool identifies common hazards and possible solutions to reduce incidents that could lead to injuries or deaths. Each drilling and servicing company should have its own safety program:

 

  

Know the hazards. Evaluate the hazards at the worksite. Many companies within the oil and gas industry use the Job Safety Analysis Process (also referred to as a JSA, Job Hazard Analysis, or JHA) to identify hazards and find solutions. Establish ways to protect workers, including developing and implementing safe practices for: o Confined space; excavations o Chemical handling; exposure o Chemical storage o Electrical work o Emergency response o Equipment/machine hazards o Fall protection o Fire protection o Hot work, welding, flame cutting operations o Personal protective equipment use o Power sources (lockout/tagout provisions, safe distance from power lines) o Working in the heat, long shifts Provide personal protective equipment (PPE). When engineering controls alone cannot protect worker overexposure to chemicals, noise, or other hazards, the employer must provide PPE. Communicate the hazards, and train workers. Have a plan for contractor safety and training.
