Precautions for using high-purity helium cylinders

Helium, high-purity helium

The pressure is generally 15MPa. In use, YQY-12 or 152IN-125 pressure reducers should be used after pressure reduction. Before use, the gas pipeline should be checked for leaks using soapy water to ensure that there are no leaks.

2. Ensure that there are no leaks of high-purity helium gas and that the workplace is well ventilated.

3. The packaging tube should indicate the production date, including the service life. All expired gas cylinders must be sent to the department for safety inspection before they can be reused.

4. When using exhaust gas in each high-purity helium gas cylinder, the residual pressure inside the cylinder should be maintained at 0.5 MPa and not less than 0.25 MPa. The bottle valve should be closed to ensure gas quality and safe use.

Bottled high-purity helium gas should be classified and stacked during transportation, storage, and use.

6. Do not approach open flames and heat sources. Do not approach fire, do not touch oil or wax, do not expose to direct sunlight, do not throw again, do not collide, do not collide or form an arc on the cylinder.

7. Random loading and unloading are strictly prohibited. High purity helium cylinders are transported short distances using specialized cylindrical carts, while they are transported long distances using dangerous goods transport vehicles.

The temperature of liquid helium is -268.9 ℃, and contact with the skin can cause severe frostbite.
