Fuel gas and oxygen are essential to soldering operations and, though they can be extremely dangerous, when you know how to store and use them with unwavering attention to safety steps, they can be very safe. Follow all precautions to ensure your operation is as safe and dependable as it can be.

If you use your torch with compressed air, dedicate that torch for ONLY compressed air and fuel, and NEVER switch it back to oxygen and fuel operation.

NEVER use an oxygen regulator for compressed air. Oxygen must never be allowed to contact grease, oil or other petroleum-based substances. In the presence of oxygen, these substances become highly explosive and can ignite and burn violently. Once your designated torch has been used with compressed air, it should not be used again with oxygen unless the oxygen hose is replaced with a new one and the correct oxygen regulator is installed.

Store all fuel and oxygen tanks safely in an appropriate carrier or securely chain them to a wall to reduce the risk of valve damage that could potentially cause a dangerous release of compressed gas.

Always engage the main tank shut-off after every use.

Purge all fuel and oxygen lines before each use to ensure no mixed gases remain in the torch system.

Always check all connections for any possible leaks whenever you're setting up tank and torch systems and whenever you're changing tanks.

Always wear safety equipment when soldering, brazing or welding.

Always use flashback arrestors and check-valves in lines to prevent a hose fire from reaching the tank.
