Disclaimer
Anything that launches a projectile through combustion is inherently dangerous! Use common sense and basic safety rules. The same rules apply to potato cannons as to firearms – follow them, and stay safe:
1. Never point the potato cannon at something you’re not willing to destroy
2. Treat the cannon as if it’s loaded at all times. Never look down the barrel!
3. Know what’s beyond your target!

Also remember that PVC/ABS pipe and PVC/ABS fittings are not approved by the manufacturer to be used for the purpose of constructing potato guns.
GENERAL SAFETY TIPS
Besides the obvious dangers of the spud gun where it relates to a projectile firing weapon, some other safety measures should be observed, since the construction of the spud gun has a few safety hazards to point out:
1. Be careful cutting the PVC or ABS pipe for the spud gun barrel and chamber.
2. Use caution with the PVC and ABS adhesives because they are inherently toxic, foul smelling, and flammable.
3. Remember that the fuels used in a combustion potato gun are inherently flammable, volatile, and can explode! That’s what we want, but we want it in a controlled environment! Propane, hairsprays, butane, and other flammable aerosols and fluids are perfectly dangerous all by themselves, so use common sense in their handling.
4. Treat the spud gun for what it is – a type of cannon. It’s not a toy, so don’t treat it like one! Adult supervision is ALWAYS required.
5. Don’t underestimate the force of the cannon. Yes, your bullets are potatoes, but a potato fired off at high speed is capable of causing anything from concussions to depressed skull fractures and even death. Don’t shoot people or animals with your spud gun!
6. If you have a misfire, don’t look down the barrel! Vent the combustion chamber for a few minutes and let the potato gun sit while pointed in a safe direction. Make sure the chamber doesn’t have any combustibles in it before attempting to extract the ammunition.
7. Don’t transport the potato gun loaded. Depending on the fuel used, even residual vapour left over from previous firings may be enough to launch the projectile, especially if the potato gun is stored in a car on a hot day. Keep the gun unloaded until ready to fire in a safe direction!
