What should be done to minimize the risk of frostbite when working with liquid oxygen?

1. Wear insulated gloves.

2. Keep skin dry at all times.

3. Limit exposure duration.

4. All of the above.

The correct answer is: All of the above.

Minimizing the risk of frostbite when working with liquid oxygen involves several important safety practices. Wearing insulated gloves is crucial because they provide a protective barrier against the extremely low temperatures of liquid oxygen, preventing direct contact that can lead to frostbite on the skin. Keeping the skin dry is also essential, as moisture can freeze quickly in the presence of liquid oxygen, increasing the chances of skin damage. Furthermore, limiting exposure duration helps reduce the overall risk by minimizing the time spent in contact with the cold substance, allowing for safer handling practices. By incorporating all of these practices—wearing insulated gloves, maintaining dry skin, and limiting exposure duration—you create a comprehensive approach to safety when dealing with liquid oxygen. Each method addresses a different aspect of the risk, making them collectively effective in reducing the likelihood of frostbite.
