Correct storage procedures for tanks of HFO-1234yf include:

1. All of the answers are true

2. Mixing with other gases

3. Using within 60 days

4. Storing in direct sunlight

The correct answer is: All of the answers are true

The correct answer encompasses the idea that proper storage procedures for tanks of HFO-1234yf are critical for safety and compliance with regulations. When assessing the procedures for storing this refrigerant, it's essential to recognize that safe practices include ensuring that tanks are not mixed with other gases, as this can lead to reactions that may be hazardous. Moreover, the recommendation to use HFO-1234yf within a specific timeframe, such as 60 days, suggests that refrigerants have a shelf life, and using them promptly ensures their efficacy and safety. This also helps prevent degradation or change in properties that can occur if left unused for extended periods. Additionally, storing refrigerants in direct sunlight can lead to increased temperatures, which may elevate pressures and potentially cause safety hazards, making it a prohibited practice. Thus, none of the distinct storage procedures conflict with the concept of safe handling and storage of HFO-1234yf, validating the choice that all pertinent practices listed under the options provided are indeed true. In summary, recognizing that no single option contradicts the principles of safe and effective storage practices contributes to understanding why the statement that all provided answers are true is indeed accurate.
