Flashcards in BA 001: Intro to Respiratory Protective Equipment Deck (14):
What is the definition of respiration?
The transport of oxygen from the outside air to the cells in body tissues, and the reverse for carbon dioxide
How much oxygen and carbon dioxide is inhaled and exhaled?
Inhaled: 21% oxygen, 0.04% carbon dioxide
Exhaled: 16% oxygen, 4% carbon dioxide
Consumption rates are influenced by what factors?
How does the body dissipate any excess heat?
How much should BA wearers drink after stenuous use?
At least half a little within 30 minutes
Heat stress may cause firefighters to suffer from what effects?
What is the policy number for RPE and breathing apparatus in the LFB?
Respiratory hazards can be divided into what two categories, and what do they mean?
Immediate risk of injury if the RPE is removed
Longer term risk of injury if the RPE is removed
What RPE does the LFB provide to be used at incidents and training?
Standard duration breathing apparatus (SDBA)
Extended duration breathing apparatus (EDBA)
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?
Rotate crews, so BA teams can rest
Make sure the rest areas are in the shade
Make sure the BA wearers don't perform in any other duties
Cool hands, arms and wrists with water (radial cooling)
Have the attendance of the LAS
