What is a risk associated with improper handling of oxygen in oxyfuel cutting?

• A. It can cool the cutting process significantly.
• B. It may cause an unexpected increase in flame size.
• C. It can create an explosive hazard when combined with flammable substances.
• D. It decreases the overall cutting quality.

Answer: (C)

The handling of oxygen in oxyfuel cutting is critical because oxygen supports combustion. When oxygen is improperly handled or stored, and if it comes into contact with flammable materials or contaminants, it can enhance combustion to the point of creating a fire or even an explosion. This risk arises because oxygen accelerates the burning of flammable materials, significantly raising the potential for hazards in the work environment. In contrast, while improper handling might lead to other issues, such as those related to flame size or cutting quality, the unique property of oxygen as a fuel enhancer makes its improper handling especially dangerous. Oxygen does not burn itself but increases the intensity of any fire it fuels, creating an explosive risk in combination with flammable substances. This is why safety precautions around oxygen handling are paramount in oxyfuel cutting operations.
