  1. Unit Six Chemical Protective Clothing and Equipment (CPC&E)

  2. Objectives • Identify classification components of Chemical Protective Clothing and Equipment (CPC&E) • Discuss the factors that contribute to the selection CPC&E • Discuss the four levels of protection • Cite basic steps in donning and doffing a level C chemical protective clothing • State basic steps in donning and doffing an air-purifying respirator • List key procedures involved in the inspection of CPC&E B461 Course

  3. Chemical Protective Clothing & Equipment (CPC&E) • Chemical Protective Clothing and Equipment (CPC&E) is worn to prevent harmful chemicals or agents from contacting: • Skin and eyes, and • Respiratory System • Provides a barrier between the body and chemical • Chemicals can have detrimental effects on skin and respiratory system during contact • Chemicals can affect target organs or organ systems B461 Course

  4. Classification Components • CPC Classified by: Style, Protective Materials; and Single-use • Styles: • Fully Encapsulating Chemical Protective (FECP) Suit • Non-encapsulating Chemical Protective (NECP) Suit • Protective Materials: • Elastomers (plastic-like) materials, stretches, etc. • Non-elastomers, non-stretchable fabrics • Single-use: Disposable garments, inexpensive B461 Course

  5. EPA Levels of Protection • Four levels of protection: A, B, C, and D • Selection is based upon required protection needed • Disposal chemical protective clothing is • First choice and better alternative • Types of chemical protective gloves are: • Neoprene, Nitrile, PVC, and Rubber • OSHA regulations require employee training before use B461 Course

  6. Level A Protection • Level A - Highest level of respiratory protection: • SCBA; or • Air line with an escape provision • Highest level of skin protection • FECP (vapor tight) suit B461 Course

  7. Level B Protection • Level B - Highest level of respiratory protection: • SCBA; or • Air line with escape provision • Lessor skin protection • NECP suit B461 Course

  8. Level C Protection • Level C - Lesser level of respirator protection • Air-purifying respirator, • PAPR • With appropriate cartridges or filter elements • Same skin protection as level B • NECP Suit B461 Course

  9. Level D Protection • Level D: • No respiratory or skin protection • Designed to be worn in the clean area • Scrub suit, cap, gown, mask, eye protection, gloves, and rubber shoe covering, where applicable B461 Course

  10. Performance Requirements • Chemical Resistance • Strength • Flexibility • Thermal Limits • Cleanability • Lifetime • Visibility • Cost B461 Course

  11. Chemical Resistance Terms • Degradation --- Results from Chemical Reaction • Penetration --- Leakage Due to Design Faults • Permeation --- A Chemical Liquid or vapor has Moved Through the Protective Materials on a Molecular Level B461 Course

  12. Chemical Chemical Inside Surface Outer Surface Permeation • Contact of Chemical at Outside Surface • Diffusion of Chemical Through Material • Chemical Passes Through to the Inside Surface Material or Fabric B461 Course
