Four answers
Standard duration breathing apparatus (SDBA)
Extended duration breathing apparatus (EDBA)
Respirators
Powered respiratory protective suits
What is the purpose of BA?
To reduce risk of respiratory injury to firefighters and provide safe working practices
Who is responsible for ensuring that RPE is work whenever personnel are committed to dangerous atmospheres?
The Incident Commander (IC)
What should be worn where the hazard involves airborne particulates and conditions are not expected to deteriorate?
A Dual-purpose facemask (DPFM) with a P3 particulate filter cartridge (FC)
Name some methods to limit heat build up and stress for BA crews?
Six answers
Rotate crews, so BA teams can rest
Make sure the rest areas are in the shade
