Propane Cylinder Safety

Canada has strictly enforced safety regulations related to the safe use of propane. Thatís one reason why incidents involving propane tanks are rare.

  • All propane cylinders must have a decal identifying the contents as a flammable gas.
  • Only a qualified technician may fill your cylinder. It is illegal for an attendant to fill an outdated cylinder, or to fill a cylinder beyond 80% capacity.
  • All cylinders must be inspected and re-qualified or replaced every 10 years. A date stamp on the collar of the cylinder indicates when it was last qualified.
  • Just because a propane cylinder hasn't reached its 10-year limitation, doesn't mean it shouldn't be replaced. Check your tank closely. If it is rusty, damaged or you just aren't sure if it's reliable, don't take unnecessary risks. Replace it with a new one and be certain of your safety.
  • When you do get a new propane cylinder, make sure you turn the old one in so that it can be properly purged and recycled or disposed of.

As with any fuel, safety must come first whenever you transport, handle and store propane. Taking the extra few minutes to ensure you handle your cylinder properly and transport it safely minimizes risk and avoids potential incidents or harm. Please follow these guidelines:

When Transporting Cylinders

  • Always thread the special plug into the outlet of the service valve as soon as you disconnect the hose.
  • Always carry the cylinder in an upright position with the safety valve on top.
  • Never put a propane cylinder in a closed vehicle. If it is in the trunk, block the trunk lid open. It is preferable to transport it on the floor of the passenger compartment.
  • Secure the cylinder in the upright position so it can't tip over while you're driving.
  • When it is inside the passenger compartment have all the windows open.
  • Never leave a cylinder in a parked vehicle with the windows up. Heat builds up quickly and could cause an explosion.
  • When reconnecting the cylinder make sure it is secured in place on the barbecue.
  • After the hose is reconnected, check for leaks using the water and soap solution. If there are bubbles tighten the connection.
  • Never smoke while handling a propane cylinder.

When Cylinder is in Use

  • Keep cylinders upright on a firm footing
  • Place cylinder outside
  • Keep cylinder away from flame or heat and building exits
  • Cylinder valve must be fully opened
  • Use only with appliances approved for propane
  • After connection, check for leaks with soap suds (never use a flame)
  • Never smoke while handling a propane cylinder

When Cylinder is Not in Use

  • Keep cylinder upright on a firm footing
  • Store cylinder outside and off the ground on a base that will not burn
  • Close cylinder valve tightly, even when empty
  • Ensure cylinder valve is protected
  • Store away from flame or heat
  • When storing disconnected cylinders, plug or cap all cylinder outlets
