Ensuring Clean Compressed Air for Safe Scuba Diving: A Guide by Aloha Diving in Phuket

When it comes to scuba diving, the quality of the air you breathe underwater is just as important as the beauty of the marine life you encounter. At Aloha Diving in Phuket, we prioritize your safety by ensuring the highest standards of compressed breathing air quality. This article will help you understand why clean air is crucial for scuba diving and how Aloha Diving adheres to the stringent DIN EN 12021:2014 standards.

Why Clean Compressed Air Matters for Scuba Divers

Breathing clean air underwater is vital for your health and safety. Contaminated air can cause serious health issues such as dizziness, headaches, and even more severe conditions. As a diver, you rely on the air in your tank to be pure and free from harmful contaminants. Here’s why clean air is essential:

  • Health and Safety: Ensuring that the air is free from toxins like carbon monoxide and oil mist prevents potential health risks.
  • Comfort and Performance: Clean air helps you breathe easily and comfortably, enhancing your diving experience.
  • Equipment Longevity: Pure air prevents damage to your diving equipment, ensuring it functions properly.

Understanding DIN EN 12021:2014 Standards

DIN EN 12021:2014 is an international standard that specifies the requirements for the quality of compressed breathing air. At Aloha Diving, we strictly adhere to these standards to guarantee the safety of our divers. Here’s a breakdown of the key requirements:

  1. Oxygen Content:
    • The air must contain 20% to 22% oxygen, similar to natural atmospheric air, ensuring it is safe to breathe.
  2. Carbon Dioxide (CO2):
    • CO2 levels must be below 500 ppm (parts per million) to avoid issues like dizziness and impaired judgment.
  3. Carbon Monoxide (CO):
    • CO must not exceed 5 ppm as it is a highly toxic gas, even in small amounts.
  4. Oil Mist:
    • The air should contain less than 0.1 mg/m³ of oil to prevent respiratory issues and equipment damage.
  5. Water Vapor:
    • The dew point, or the temperature at which water condenses, must be controlled to prevent moisture in the air tanks, which could cause equipment failure.
  6. Particulates:
    • The air must be free of harmful particulates, ensuring it is clean and safe to breathe.
