Answer :
Certainly! Let's analyze the safety guidelines concerning the working pressure of an oxygen cylinder step-by-step.
1. Understanding the Question:
- The question asks about the minimum working pressure of an oxygen cylinder that should never be allowed to drop below a certain point. This is crucial to ensure safe and effective use of the cylinder.
2. Reviewing the Choices:
- We have four options:
a. 0 psi
b. 500 psi
c. 25 psi
d. 10 psi
3. Eliminating Implausible Options:
- 0 psi: If the pressure drops to 0 psi, the cylinder is essentially empty, and no oxygen would be available. This is unsafe, especially in critical situations where a continuous supply of oxygen is required. Hence, 0 psi is not a viable option.
- 25 psi: While 25 psi may provide some residual oxygen, it is generally considered too low to ensure a reliable supply, especially as the cylinder's pressure can further drop quickly under usage.
- 10 psi: Similar to 25 psi, 10 psi is also dangerously low and might not provide an adequate supply of oxygen in emergencies or high-demand scenarios.
4. Considering the Best Practice:
- 500 psi: This is typically considered a safe and recommended minimum pressure level for oxygen cylinders. At 500 psi, there is a significant enough reserve to ensure that oxygen supply remains available for immediate needs and during emergencies. This pressure level acts as a buffer, ensuring that users are alerted to refill or replace the cylinder before it gets critically low.
5. Conclusion:
- Given the safety practices and common guidelines, the best practice is to ensure that the oxygen cylinder's working pressure does not drop below 500 psi. This ensures a safe, reliable supply of oxygen at all times.
Thus, the correct answer is:
b. 500 psi
