Why is it recommended to use all the contents of the Tundra Fire Extinguishing Spray can on the fire? Can I save the rest of the contents for later use?

When using on a fire, all the contents of the Tundra Fire Extinguishing Spray should be used to help prevent the flame from re-igniting. Since cleanup of the fire extinguishing discharge is so easy, use the entire product, just to be safe. Additionally, it is recommended that you should replace your Tundra™ once you have partially used it so that you can be sure to have enough fire extinguishing spray to protect your home in the future.
