13. What is confined space safety in oil and gas?

Answer: Confined spaces (tanks, vessels) can trap toxic gases, have low oxygen, or risk engulfment. Proper ventilation, gas testing, and rescue planning are required.

14. What is a gas test, and why is it important?

Answer: A gas test measures oxygen levels, toxic gases, and explosive gases before entry into confined spaces or hazardous areas.

15. What is PPE in the oil and gas industry?

Answer: Personal Protective Equipment includes:

• Flame-resistant clothing (FRC)
• Hard hats and safety boots
• Respiratory protection (masks, SCBA)

16. What is Lockout/Tagout (LOTO)?

Answer: LOTO ensures energy sources (electrical, mechanical) are isolated before maintenance to prevent accidental activation.

17. What is the difference between a hazard and a risk?

Answer:

• Hazard: A potential source of harm
• Risk: The probability of the hazard causing harm

18. What are the types of oil spill response methods?

Answer:

• Booms and skimmers
• Chemical dispersants
• Bioremediation

19. What is an emergency evacuation plan?

Answer: A structured procedure to safely exit a facility in case of fire, explosion, or toxic gas release.

20. How do you control static electricity in oil and gas operations?

Answer:

• Use grounding and bonding
• Avoid synthetic clothing
• Control humidity levels

21. What are the dangers of working at height in oil and gas?

Answer: Falls can occur from platforms, derricks, or scaffolding, leading to severe injuries or fatalities.

22. How do you prevent falls in oil and gas facilities?

Answer:

• Use harnesses and lifelines
• Ensure guardrails and handrails

23. What is a blowout preventer (BOP)?

Answer: A BOP is a safety device that controls uncontrolled well blowouts by sealing the well.

24. What are common drilling hazards?

Answer:

• Kickbacks and blowouts
• Pipe handling injuries

25. What is Process Safety Management (PSM)?

Answer: A system to prevent releases of hazardous substances by managing process safety elements.

26. What is a near miss?

Answer: An unplanned event that could have resulted in an accident but was avoided.

27. How do you ensure crane safety in oil and gas?

Answer:

• Conduct pre-use inspections
• Use certified operators

28. What is a JSA (Job Safety Analysis)?

Answer: A method to identify hazards in a specific job task and implement control measures.

29. What is a blowout in drilling operations?

Answer: An uncontrolled release of oil or gas due to pressure imbalance.

30. How do you control blowouts?

Answer: By using blowout preventers (BOPs) and proper well control procedures.

31. What is an MSDS, and why is it important?

Answer: A Material Safety Data Sheet provides safety information on hazardous chemicals.

32. What are the dangers of benzene exposure?

Answer: Long-term exposure can cause cancer, dizziness, and respiratory issues.

33. What are the different types of offshore safety hazards?

Answer:

• High waves and extreme weather
• Helicopter transport risks

34. How do you ensure offshore helicopter safety?

Answer:

• Proper pre-flight safety checks
• Wearing Helicopter Underwater Escape Training (HUET) gear

35. What is a fire triangle?

Answer: The three elements needed for fire:

• Fuel
• Oxygen
• Heat
