Self-Contained Breathing Apparatus

This training skill will enable participants to safely and effectively use a self-contained breathing apparatus during normal occupational assignments and emergency operations.

The learner will possess the fundamental knowledge and skills to ensure that respiratory protection is not intentionally compromised and hazardous areas are exited prior to air depletion.

Content:

• Physiology of respiration
  • Functions of normal human respiration with reference to the flow of air through the respiratory tract.
  • Functions of normal human respiration with reference to the flow of air through the respiratory tract.
  • Physiological signs of reduced oxygen in the atmosphere.
• Explain the nature and characteristics of common hazardous atmospheres
  • Common hazardous atmospheres
  • Conditions occurring in each of these hazardous atmospheres
  • Most common gases found during fires
• Limitations of a self-contained breathing apparatus 
  • Limitations of the equipment of a self-contained breathing apparatus.
  • Impact on the wearer’s performance
  • The limitations of the air supply in a self-contained breathing apparatus.
• Components of a self-contained breathing apparatus and their functions  
  • Open and closed-circuit types.
  • Functions of all components of a self-contained breathing apparatus in the context of emergency services operations.
  • The flow of air through a self-contained breathing apparatus, with reference to the consequences of correct or incorrect usage.
• Maintaining a self-contained breathing apparatus in a state of readiness
  • Routine inspection of a self-contained breathing apparatus
