  1. Unit 3.3 Personal Protective Equipment (Core)

  2. Objectives • Describe the principles of hazards based response • Identify protective measure considerations for life saving rescues • Determine appropriate PPE • Identify basic capabilities and limitations of various types of PPE Unit 3.3  2

  3. Hazard Based Response The process of developing personal protective measures designed to specifically address the hazards that are present at the scene in order to achieve an acceptable level of risk Unit 3.3  3

  4. Hazard Based Response • Acceptable risk • Step 1: Identify hazards • Step 2: Develop measures to reduce each hazard Unit 3.3  4

  5. Identify and Reduce Hazards • Thermal • Etiological • Asphyxiation • Mechanical/Electrical • Chemical • Psychological • Radiological Unit 3.3  5

  6. Personal Protection • Minimum level of protection for operations level responders Unit 3.3  6

  7. Respiratory Protection • Air Purifying Respirators (APRs) • Limitations and use criteria • 100:1 PF for full face • Supplied Air Breathing Apparatus (SABA) • Tethered air lines with escape capability • 10,000:1 PF for positive pressure • Positive Pressure SCBA • Highest level of protection, 10,000:1 PF Unit 3.3  7

  8. Dermal Protection • Support garments (NFPA 1993) • Specialized thermal • Splash protective • Vapor protective Unit 3.3  8

  9. Level “C” Protective Clothing • Respiratory: APR • Dermal: Splash • Limitations: • Must know contaminant • Must measure • Must have 19.5% O2 • Must have proper filter Unit 3.3  9

  10. Level “B” Protective Clothing • Respiratory: PP/SCBA or SABA • Dermal: Splash • Minimum for unknown • Limitations: • Not for IDLH skin • Excellent respiratory • Used for incidental splash only Unit 3.3  10

  11. Level “A” Protective Clothing • Respiratory: PP/SCBA • Dermal: Vapor protective • Limitations: • No thermal protection • High heat stress hazard • Good for repeated contact or high vapor concentrations Unit 3.3  11

  12. Summary Table of Levels Unit 3.3  12

  13. Summary • Hazards based response • Personal protective equipment Unit 3.3  13
