How does increased pressure at depth affect your body, and what measures do you take to mitigate these effects?
How to Answer
- 1
Explain how pressure increases affect gas solubility in the body.
- 2
Discuss potential physical effects like nitrogen narcosis and oxygen toxicity.
- 3
Mention the importance of descent and ascent rates to avoid decompression sickness.
- 4
Talk about the use of specialized equipment like dive computers.
- 5
Highlight the significance of training and following safety protocols.
Example Answers
Increased pressure causes gases, especially nitrogen, to dissolve more readily in body tissues, which can lead to nitrogen narcosis if not managed properly. I mitigate this by ascending slowly and ensuring I follow my dive computer's instructions to avoid decompression sickness.
What are the differences between underwater welding techniques and procedures compared to surface welding?
How to Answer
- 1
Emphasize the environmental challenges of underwater welding such as visibility and water pressure
- 2
Mention the specific welding techniques used underwater like wet welding and dry welding
- 3
Highlight the differences in safety measures due to the underwater environment
- 4
Discuss the impact of water on welding materials and methods
- 5
Note the equipment differences, such as the need for diving gear and underwater arc welding machines.
Example Answers
Underwater welding techniques differ primarily due to the challenging environment. For instance, while surface welding uses conventional methods, underwater welders often use wet welding or dry welding to cope with water pressure. Additionally, safety measures are more stringent because of the risks associated with diving and working in a submerged environment.
Can you explain the concept of decompression sickness and how you prevent it during commercial diving operations?
How to Answer
- 1
Define decompression sickness clearly as the formation of gas bubbles in the body due to rapid ascent.
- 2
Explain the mechanisms, including nitrogen absorption and off-gassing during dives.
- 3
Discuss preventive measures like controlled ascent rates and safety stops.
- 4
Mention the use of dive tables and computers to plan dives and manage nitrogen levels.
- 5
Emphasize the importance of hydration and physical health before diving.
Example Answers
Decompression sickness, or 'the bends', occurs when nitrogen bubbles form in the body due to rapid ascent. To prevent it, I always follow controlled ascent rates and perform safety stops at 5 meters for 3 minutes. I use dive tables to ensure I'm not exceeding my no-decompression limits and stay hydrated before and after dives.
Explain the techniques you use for maintaining buoyancy control during a hard hat dive.
How to Answer
- 1
Describe your pre-dive buoyancy checks with weights.
- 2
Explain the use of your buoyancy control device (BCD) for adjustments.
- 3
Discuss how you manage your breathing to aid buoyancy.
- 4
Mention the importance of water depth awareness while diving.
- 5
Include the role of neutral buoyancy in your diving technique.
Example Answers
I start with a pre-dive buoyancy check to adjust my weights correctly. Once underwater, I use my BCD to make fine adjustments. Controlled breathing also helps; I inhale deeply to rise and exhale to sink. I always keep track of the water depth to avoid buoyancy loss.
What is the purpose of a hyperbaric chamber, and when would it be used in diving operations?
How to Answer
