Check the tank’s labeling or documentation for any disposal instructions from the manufacturer.

• Take the tank to a well-ventilated outdoor area.
• Open the valve completely to ensure all helium is released.
• Check that the pressure is at zero by pressing down on the nozzle to verify
  no sound of gas is escaping when the valve is briefly opened.

Important: Helium is non-toxic but can displace oxygen—always vent outdoors.

• Clearly label the tank with “EMPTY” and “DO NOT REFILL” using a permanent marker or sticker.
• For added clarity, you can remove or disable the valve, or drill/punch a hole in the tank (if safe and legal to do so).

If you are not trained or equipped to do this, move to step 5 and have a facility handle it.

• Many U.S. scrap yards and metal recyclers accept empty steel gas cylinders, but policies vary.
• Call ahead to confirm they accept steel helium tanks and ask if they require the valve removed or tank punctured.
• You can find local recyclers via:

1. Earth911 Recycling Locator
2. Your city or county’s waste management department

• Ensure the tank is clearly marked as empty.
• Secure the tank upright during transport to avoid rolling or shifting.

• For commercial or fleet operations, log the tank’s serial number and disposal date.
• This helps with inventory control and compliance with OSHA or FAA standards if applicable.

• Do not throw the tank in household trash or dumpsters.
• Never dispose of pressurized or partially full tanks—this is a safety hazard
  and may violate local or federal regulations (e.g., DOT, EPA).
