What is the purpose of the harness assembly in the SCBA?

• To connect the SCBA to the rapid intervention crew universal air connection

• To provide a platform for all the SCBA components to attach to the user

• To regulate the flow of air to the facemask

• To store the low pressure line for emergency breathing support

What is the function of the regulator in the SCBA?

• To attach the low-pressure hose to the facemask

• To provide breathable air at a lower pressure

• To bypass the regulator assembly and provide continuous air

• To vibrate when the cylinder pressure reaches one quarter of its capacity

What is the purpose of the donning and doffing button on the regulator?

• To lower the high pressure of the air in the cylinder to a breathable lower pressure

• To bypass the regulator assembly and provide continuous air

• To vibrate the regulator when the cylinder pressure reaches one quarter of its capacity

• To temporarily stop the flow of air while donning or doffing the regulator

What is the function of the purge valve on the regulator?

• To temporarily stop the flow of air while donning or doffing the regulator

• To vibrate the regulator when the cylinder pressure reaches one quarter of its capacity

• To bypass the regulator assembly and provide continuous air

• To release excess air from the regulator assembly

What is the purpose of the control console assembly in the SCBA?

• To provide a platform for all the SCBA components to attach to the user

• To connect the SCBA to the rapid intervention crew universal air connection

• To house the remote pressure gauge, manual pass alarm button, and pass alarm reset button

• To lower the high pressure of the air in the cylinder to a breathable lower pressure

What is the function of the pressure reducer in the SCBA?

• To vibrate when the cylinder pressure reaches one quarter of its capacity

• To bypass the regulator assembly and provide continuous air

• To provide breathable air at a lower pressure

• To attach the low-pressure hose to the facemask

What is the purpose of the rapid intervention crew universal air connection?

• To fill a cylinder from the RIC pack in an emergency

• To bypass the regulator assembly and provide continuous air

• To vibrate the regulator when the cylinder pressure reaches one quarter of its capacity

• To temporarily stop the flow of air while donning or doffing the regulator
