Safety rules for handling argon cylinders:

 Here are some safety rules for handling argon cylinders:

Handling

Only a competent person should handle the cylinder. Use a hand truck to move the cylinder, and never drop, roll, or slide it. 

Storage

Store the cylinder in a shed that's isolated, well-ventilated, and protected from direct sunlight. Keep it away from exits, damp areas, and sources of heat, fumes, or corrosive chemicals. Store full and empty cylinders separately, and keep incompatible cylinders at least 3 meters apart. 

Use

Keep the cylinder upright when filling, storing, transporting, and using it. Close the valve after use, and keep the cylinder away from electricity. Don't use the cylinder as a roller or packing support. 

Personal protection

Wear safety glasses with side shields, and gloves if necessary. 

Other precautions

Don't change the color of the cylinder, or tamper with the markings on it. Don't use oil or grease on the cylinder, as it can cause an explosion. Use a valve protection guard on the cylinder. 

Environmental protection

Check that emissions from ventilation or work process equipment comply with environmental protection legislation.

Argon can be hazardous because it can cause suffocation if it mixes with oxygen in the air. Symptoms include headache, rapid breathing, dizziness, confusion, tremors, loss of coordination and judgment, and lightheadedness
