Do not place a propane cylinder in household trash or curbside recycling. Keep the valve closed, store and transport it upright away from heat, and ask a propane supplier or local HHW program whether it accepts that cylinder size and condition.
Choose the route by condition
| What you have | Best first call |
|---|---|
| Refillable cylinder in date | A propane supplier may inspect and refill or exchange it. |
| Exchange-brand grill cylinder | Use the brand or retailer's exchange instructions. |
| Small disposable cylinder | Ask HHW; do not assume an exchange cage accepts it. |
| Rusted, leaking, or fire-damaged | Keep away from ignition and contact emergency or hazardous-waste staff. |
Prepare it before you load
- Read the cylinder markings without altering the tank.
- Close the valve and install a protective cap if designed for one.
- Keep it upright and ventilated during transport.
- Tell staff about damage or suspected leakage before unloading.
“Empty” is not a safe visual judgment
A cylinder can retain vapor and pressure after an appliance stops operating. Puncturing, drilling, cutting, or deliberately venting it can create a fire, explosion, and exposure hazard. Scrap yards often require proof that a cylinder was professionally depressurized and prepared.
Never leave a cylinder in a hot vehicle or place it where it can roll and damage the valve. If you smell gas, hear leaking, or see severe corrosion, avoid switches, flames, and vehicles; move away and contact the fire department or supplier for location-specific instructions.

Common mistakes
- Drilling or shooting a cylinder
- Putting it in a metal-recycling bin
- Leaving it in a closed hot vehicle
- Assuming rust or age means it has no pressure
Questions to ask before the trip
- Do you accept refillable and disposable cylinders?
- What sizes and quantity limits apply?
- Will you accept a damaged or leaking cylinder?
- Is an appointment or proof of residency required?
