How should old helium cylinders be disposed of?
Helium cylinders should be disposed of properly to avoid the risk of explosion or injury. Here are the steps to follow:
- Depressurize the cylinder: Open the cylinder valve slowly and allow all the helium to escape.
- Remove the regulator: Once the cylinder is depressurized, remove the regulator and any attached hoses.
- Check for leaks: Spray soapy water around the cylinder valve and regulator to check for leaks. If you see bubbles, tighten the valve or replace the regulator.
- Wrap the cylinder in plastic: Wrap the cylinder in plastic wrap or tape to secure the valve and prevent damage during transport.
- Dispose of the cylinder at a hazardous waste facility: Contact your local hazardous waste disposal facility to arrange for proper disposal.
