Common Causes of Injury in the Oil and Gas Industry – Struck-By, Caught-In, or Caught-Between Incidents

Print a Sign-In SheetSpanish Version Coming Soon

According to OSHA’s statics, struck-by, caught-in, and caught-between hazards are the number one cause of fatalities at well sites. There are multiple sources in which employees can be exposed, including moving vehicles or equipment, falling objects, and high-pressure lines.

Visibility for equipment operators can be very limited at times. Therefore, employees should never place themselves near or in the possible path of moving equipment.

  • Never assume the equipment operator knows you are there or can see you. Assumptions are the recipe for disaster.
  • Wear reflective, high-visibility clothing that can be seen by drivers.
  • Never place yourself in a position where oncoming equipment could strike you.
  • Always communicate directly with the equipment operator when approaching the area.
  • Never stand near a piece of equipment while it is in operation.
  • Avoid being under heavy equipment. For example, ensure that floor hands are aware of the condition of wire ropes, slings, blocks, and other parts that could result in falling heavy equipment and tools above them.
  • Secure pressurized lines that could whip when loose.
  • Establish work zones during high-operating-pressure activities and keep other-than-essential personnel out of these zones.

Machinery can also pose hazards, with many moving parts or rotating shafts. Never work on or reach into moving parts or machinery. Properly maintain and always use the guards provided on the equipment, they act as a barrier between the moving parts and your body. Turn machinery/equipment off and use lockout/tag-out procedures before adjusting, repairing or servicing.

Never place your body under or between two pieces of equipment or the equipment and a stationary object unless it is de-energized and blocked against motion.

Look for possible hazards before you start a task. Take the time to plan out your actions and decide the necessary steps to work safely. Give your work your full attention.

Take the time to learn the possible struck-by, caught-in, or between hazards in your work area so you don’t learn about the consequences first hand.
