Your carbonating cylinder is a 100% safe addition to your home but we think it's important to highlight some basic safety guidelines and extreme use scenarios that you should avoid. Sparkle safety first! Always store your carbonating cylinder in a cool and dry environment. The carbonating cylinder must not be exposed to sources of heat (such as prolonged travel in the trunk of a car) or placed right next to a heat source such as an oven, stove or fireplace. Every carbonating cylinder is fitted with a unique safety valve which will safely release the gas in the unlikely event the pressure in the carbonating cylinder rises.
