- 1. Awareness-Level Lesson 4 Presentation HazardousMaterials for First Responders, 3rd Ed.
- 2. Awareness Level 4–2 Typical Componentsof PPE • Respiratory equipment • Protective clothing – Structural fire-fighting protective clothing – High-temperature protective clothing – Chemical protective clothing
- 3. Awareness Level 4–3 What AppropriatePPE Protects • Skin • Eyes • Face • Hands • Feet • Body • Head • Respiratory system (1 of 2)
- 4. Awareness Level 4–4 What AppropriatePPE Protects (2 of 2)
- 5. Awareness Level 4–5 PPE andHazardous Materials • Structural fire-fighting and high-temperature protective clothing — Offer limited protection against chemical hazards • Chemical-protective clothing — Offers protection against hazardous materials – Requires training above the first responder Awareness Level
- 6. Awareness Level 4–6 Requirements ofPPE • NFPA standards state requirements for personal protective equipment – Design – Certification – Testing
- 7. Awareness Level 4–7 Structural Fire-Fighting ProtectiveClothing • Provides protection from: – Heat – Moisture – Ordinary hazards associated with structural fire fighting
- 8. Awareness Level 4–8 Components ofStructural Fire- Fighting Protective Clothing • Helmet • Coat • Pants • Boots • Gloves • Personal alert safety system (PASS) device • Hood
- 9. Awareness Level 4–9 Limitations ofStructural Fire-Fighting Clothing • Limited protection against hazardous materials – Neither corrosive-resistant nor vapor-tight – Gaps occur in clothing – Chemicals can be absorbed into the equipment – Rubber or neoprene in boots, gloves, and SCBA facepieces can become permeated by chemicals and rendered unsafe for use
- 10. Awareness Level 4–10 Structural Fire-FightingProtective Clothing at Haz Mat Incidents • Structural fire-fighting protective clothing is commonly used at haz mat incidents when the following conditions are met: – Contact with splashes of extremely hazardous materials is unlikely – Total atmospheric concentrations do not contain high levels of chemicals that are toxic by way of skin contact – There is a chance of fire or there is a fire
- 11. Awareness Level 4–11 Purpose ofChemical-Protective Clothing and Equipment • To shield or isolate individuals from the chemical, physical, and biological hazards that may be encountered during haz mat operations
- 12. Awareness Level 4–12 Types ofCPC • Liquid-splash protective clothing • Vapor-protective clothing
- 13. Awareness Level 4–13 CPC Combinations •Single or multipiece garment • Encapsulating • Nonencapsulating
- 14. Awareness Level 4–14 Selection ofCPC • Depends on specific chemical and on specific tasks • Selection considerations: – Most CPC is impermeable to moisture – Garment’s permeation, degradation, and penetration abilities – Service life
- 15. Awareness Level 4–15 CPC Permeation •Permeation — Occurs when a chemical passes through the CPC fabric on a molecular level Chemical spill
- 16. Awareness Level 4–16 CPC Degradation •Degradation — Occurs when the characteristics of the material in use are altered through contact with chemical substances (1 of 2)
- 17. Awareness Level 4–17 CPC Degradation Anacid eating away the outer layers of structural fire-fighting protective clothing is an example of chemical degradation. (2 of 2)
- 18. Awareness Level 4–18 CPC Penetration •Penetration — Occurs when there is an opening or a puncture in the protective material (1 of 2)
- 19. Awareness Level 4–19 CPC Penetration Chemicalscan penetrate PPE through gaps, tears, punctures, or other openings. (2 of 2)
- 20. Awareness Level 4–20 CPC ServiceLife • Reusable • Limited use • Disposable
- 21. Awareness Level 4–21 CPC Written ManagementProgram • All emergency responders and organizations who routinely select and use CPC should establish a written CPC management program.
- 22. Awareness Level 4–22 Positive-Pressure SCBA Components •Facepiece • Pressure regulator • Compressed air cylinder • Harness assembly • End-of-service-time indicators
- 23. Awareness Level 4–23 Advantages of Positive-PressureSCBA • Maintains air pressure inside the facepiece slightly higher than normal atmospheric pressure outside • Independence • Maneuverability
- 24. Awareness Level 4–24 Disadvantages of Positive-PressureSCBA • Heavy weight of the units • Limited air supply duration • Change in profile that may hinder mobility • Limited vision caused by facepiece fogging • Limited communications if not equipped with a microphone or speaking diaphragm
- 25. Awareness Level 4–25 Level DEnsembles • Used for nuisance contamination and used only when no atmospheric hazards exist • Provide no respiratory protection and minimal skin protection • May not be worn in the hot zone
- 26. Awareness Level 4–26 Level DEnsemble Components • Consist of typical work uniforms, street clothing, or coveralls • Includes items such as: – Gloves – Safety glasses – Boots – Hardhats
- 27. Awareness Level 4–27 Level DEnsemble Use • Atmosphere contains no hazard • Work functions preclude splashes, immersion, or the potential for unexpected inhalation of or contact with hazardous levels of any chemicals
- 28. Awareness Level 4–28 PPE Careand Inspection • The user must take all steps to ensure that the protective ensemble performs as expected • All PPE and respiratory equipment must be inspected on a routine basis • Records must be kept of all inspection procedures
- 29. Awareness Level 4–29 Summary • Personalprotective equipment is essential in emergency response. The type of PPE used depends on the specific incident. Typical PPE consists of respiratory equipment and either structural fire-fighting, high-temperature, or chemical-protective clothing. • Structural fire-fighting clothing provides very limited protection against hazardous materials. (1 of 3)
- 30. Awareness Level 4–30 Summary • Chemical-protectiveclothing provides protection against hazardous materials. No one type of CPC protects against all hazards. • Positive-pressure SCBA is often used at incidents and has both advantages and disadvantages. (2 of 3)
- 31. Awareness Level 4–31 Summary • LevelD ensembles are typical work uniforms, street clothes, or coveralls and are only appropriate for nuisance contamination. • PPE care and inspection is an important component in ensuring that PPE is properly maintained and safe for the user. (3 of 3)
