Oxygen is colorless, odorless, and flammable.
3. Applications:
- Industrial: Shipbuilding, metallurgy, mechanical processing, industrial and civil construction, high-tech laser cutting, etc.
- Aquaculture: Oxygenation for fisheries.
- Food Industry: Preservation and packaging processes.
4. Quality Standards:
- Purity: ≥ 99.7%
- Impurities: ≤ 5000 ppm
- Moisture: ≤ 5 ppm
- Argon: ≤ 4000 ppm
5. Manufacturing Process:
- Produced and filled using high-quality liquid oxygen from large storage tanks.
- All gas cylinders are inspected (KCS) and meet current safety standards and legal regulations.
6. Safety Guidelines for Liquid Oxygen Use:
Liquid oxygen is stored at extremely low temperatures and under pressure controlled by safety valves. Only trained personnel should handle it.
- Combustion Risk: Oxygen intensifies combustion. Flammable substances in contact with liquid oxygen can explode upon ignition.
- Storage and Handling:
•
Keep away from oil, grease, and direct sunlight.
•
Store and use in well-ventilated areas.
•
Maintain a minimum distance of 5 meters from ignition sources smoking is prohibited.
- Contact Precautions:
•
Avoid skin, eye, or clothing contact with liquid oxygen to prevent frostbite and cold burns.
•
Always wear protective gear (e.g., face shields, gloves) when handling liquid oxygen.
- Cylinder Handling:
•
Do not tip, or roll the cylinder. Use appropriate transport equipment.
•
Open cylinder and regulator valves slowly during use. Close valves after use, leaving a minimum residual pressure of ≥ 5 bar.
- Cold Burn Treatment: In case of exposure to liquid oxygen causing cold burns, immediately seek medical attention.
7. Medical Usage Safety Guidelines:
- Operated only by trained personnel familiar with hypoxia treatment and resuscitation.
- For medical applications, oxygen must be prescribed and monitored by healthcare professionals.
- Continuous use of high-concentration oxygen requires careful monitoring of arterial blood oxygen levels to avoid potential harm.
- Ensure oxygen cylinders are upright and use vaporizer heat exchangers and pressure-reducing equipment designed specifically for oxygen.
- Never attempt to administer oxygen to a non-breathing patient unless using appropriate resuscitation equipment under a doctor’s guidance.
By adhering to these guidelines, liquid oxygen can be used safely in industrial and medical settings to maximize its benefits while minimizing risks.
