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

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 DHS/NTC B461 Course

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 DHS/NTC B461 Course

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 DHS/NTC B461 Course

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 DHS/NTC B461 Course

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 DHS/NTC B461 Course

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

Level C Protection Same skin protection as level B NECP Suit 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 DHS/NTC B461 Course

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 DHS/NTC B461 Course

Performance Requirements Chemical Resistance Strength Flexibility Thermal Limits Cleanability Lifetime Visibility Cost DHS/NTC B461 Course

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 DHS/NTC B461 Course

Permeation Contact of Chemical at Outside Surface Diffusion of Chemical Through Material Chemical Passes Through to the Inside Surface Chemical Outer Surface Inside Surface Material or Fabric DHS/NTC B461 Course
