What must be posted in areas where O2 is stored or in use?

1. Caution signs

2. Hazardous material signs

3. No Smoking signs

4. Oxygen in use signs

The correct answer is: No Smoking signs

Oxygen presents a serious fire hazard, so areas where it is stored or in use must be strictly monitored to minimize the risk of fire. Posting a "No Smoking" sign in these areas is necessary as it informs people that there is an increased fire hazard due to the presence of oxygen. Caution signs are used to warn of potential dangers or hazards, but in this specific situation, a "No Smoking" sign is more appropriate. "Hazardous material" signs are typically used for chemicals, not oxygen. While an "Oxygen in use" sign may seem like a logical answer, it does not explicitly convey the message to not smoke, making it less effective in preventing fires in oxygen storage areas.
