What is the average wait time for a bump test?

• A. 3 Minutes
• B. 5 Minutes
• C. 10 Minutes
• D. 15 Minutes

Answer: (B)

A bump test is a quick check to confirm a gas detector still responds to a known gas and activates its alarm within the expected time. The process is kept short on purpose so it doesn’t disrupt operations: you set up the device, expose it to a test gas for a brief moment, observe the alarm and readings, and then reset and record the result. Five minutes is a practical, commonly used average because it covers all steps—from setup to verification—without being overly long. Longer times, like ten or fifteen minutes, would slow routine checks; shorter times, such as three minutes, may not reliably accommodate all steps. If the detector doesn’t respond as expected within this window, it signals a potential issue that needs maintenance or recalibration rather than a successful bump test.
