🔍 Key Concepts

• Function of the bypass (emergency) valve on a self-contained breathing apparatus (SCBA) • Normal air path: bottle → regulator → face piece • What happens when the regulator fails or demand valve doesn’t open

💭 Think About

• Think about why a bypass valve exists: what problem is it meant to solve if the regulator or demand valve is not working? • In an emergency, do you want to go through all normal control components, or provide an alternate route for air flow? • Which single component must absolutely receive air for you to keep breathing, even if other parts fail?

✅ Before You Answer

• Identify the normal route of air flow during standard operation (without bypass). • Decide whether the bypass is meant to send air to a control device or straight to the user’s breathing interface. • Make sure the option you choose does not describe air simply being dumped/wasted to the atmosphere, but instead supports continued breathing.
