What safety feature should be checked before using a gas cutting torch?

Checking the integrity of the hose and the connections is crucial before using a gas cutting torch. This safety feature helps to ensure that there are no leaks in the hoses that carry the flammable gases, such as oxygen and acetylene. If the hoses are damaged or improperly connected, there is a heightened risk of gas escaping, which can lead to fires or explosions. Ensuring that the hoses are securely attached and free from cracks or wear maintains a safe working environment and helps prevent accidents. Being proactive about these checks is a fundamental aspect of operating a gas cutting torch safely.
