🔍 Key Concepts

• Positive pressure SCBA (self-contained breathing apparatus) safety limits • Normal full cylinder pressure range and what a small vs. large discrepancy means • Why matching readings on cylinder and regulator gages is important

💭 Think About

• Think about what size pressure difference would still be considered a minor indication of error or loss, versus what would show a serious problem with the system or the gages. • Compare each choice to a typical SCBA cylinder pressure (in PSI). Which options would indicate a dangerous percentage of loss or a clearly faulty gage? • Ask yourself: in an emergency, what maximum difference between two pressure readings would still give reasonable confidence that both the gage and the system are working properly?

✅ Before You Answer

• Estimate a typical SCBA cylinder pressure (often several thousand PSI) and compare each option as a percentage of that value. • Decide which options represent an unreasonably large discrepancy that would clearly signal equipment failure. • Confirm that the value you pick would be considered a small tolerance, not a major loss of air supply.
