What type of gases must be monitored carefully during torch operations to prevent hazardous conditions?

Monitoring oxidizing gases during torch operations is crucial due to their potential to enhance the combustion process and support fire or explosions. Oxidizing gases, such as oxygen, can significantly increase the intensity of a flame and potentially lead to uncontrollable fires if not properly managed. Ensuring the levels of these gases are within safe parameters helps minimize risks and maintain a safe working environment.

Inert gases, on the other hand, do not support combustion, so they are less of a concern in terms of fire hazards during torch operations, while radioactive gases are typically not encountered in standard torch activities. Understanding the behaviors of various gases in relation to fire safety is essential for effective risk management during these operations.
