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

2 DHS/NTCB461 Course2 Objectives Identify classification components of Chemical Protective Clothing and Equipment (CPC&E) Identify classification components of Chemical Protective Clothing and Equipment (CPC&E) Discuss the factors that contribute to the selection CPC&E Discuss the factors that contribute to the selection CPC&E Discuss the four levels of protection Discuss the four levels of protection Cite basic steps in donning and doffing a level C chemical protective clothing Cite basic steps in donning and doffing a level C chemical protective clothing State basic steps in donning and doffing an air- purifying respirator State basic steps in donning and doffing an air- purifying respirator List key procedures involved in the inspection of CPC&E List key procedures involved in the inspection of CPC&E

3 DHS/NTCB461 Course3 Chemical Protective Clothing & Equipment (CPC&E) Chemical Protective Clothing and Equipment (CPC&E) is worn to prevent harmful chemicals or agents from contacting: Chemical Protective Clothing and Equipment (CPC&E) is worn to prevent harmful chemicals or agents from contacting: Skin and eyes, and Skin and eyes, and Respiratory System Respiratory System Provides a barrier between the body and chemical Provides a barrier between the body and chemical Chemicals can have detrimental effects on skin and respiratory system during contact Chemicals can have detrimental effects on skin and respiratory system during contact Chemicals can affect target organs or organ systems Chemicals can affect target organs or organ systems

4 DHS/NTCB461 Course4 Classification Components CPC Classified by: Style, Protective Materials; and Single-use CPC Classified by: Style, Protective Materials; and Single-use Styles: Styles: Fully Encapsulating Chemical Protective (FECP) Suit Fully Encapsulating Chemical Protective (FECP) Suit Non-encapsulating Chemical Protective (NECP) Suit Non-encapsulating Chemical Protective (NECP) Suit Protective Materials: Protective Materials: Elastomers (plastic-like) materials, stretches, etc. Elastomers (plastic-like) materials, stretches, etc. Non-elastomers, non-stretchable fabrics Non-elastomers, non-stretchable fabrics Single-use: Disposable garments, inexpensive Single-use: Disposable garments, inexpensive

5 DHS/NTCB461 Course5 EPA Levels of Protection Four levels of protection: A, B, C, and D Four levels of protection: A, B, C, and D Selection is based upon required protection needed Selection is based upon required protection needed Disposal chemical protective clothing is Disposal chemical protective clothing is First choice and better alternative First choice and better alternative Types of chemical protective gloves are: Types of chemical protective gloves are: Neoprene, Nitrile, PVC, and Rubber Neoprene, Nitrile, PVC, and Rubber OSHA regulations require employee training before use OSHA regulations require employee training before use

6 DHS/NTCB461 Course6 Level A Protection Level A - Highest level of respiratory protection: Level A - Highest level of respiratory protection: SCBA; or SCBA; or Air line with an escape provision Air line with an escape provision Highest level of skin protection Highest level of skin protection FECP (vapor tight) suit FECP (vapor tight) suit

7 DHS/NTCB461 Course7 Level B Protection Level B - Highest level of respiratory protection: Level B - Highest level of respiratory protection: SCBA; or SCBA; or Air line with escape provision Air line with escape provision Lessor skin protection Lessor skin protection NECP suit NECP suit

8 DHS/NTCB461 Course8 Level C Protection Level C - Lesser level of respirator protection Level C - Lesser level of respirator protection Air-purifying respirator, Air-purifying respirator, PAPR PAPR With appropriate cartridges or filter elements With appropriate cartridges or filter elements Same skin protection as level B Same skin protection as level B NECP Suit NECP Suit

9 DHS/NTCB461 Course9 Level D Protection Level D: Level D: No respiratory or skin protection No respiratory or skin protection Designed to be worn in the clean area Designed to be worn in the clean area Scrub suit, cap, gown, mask, eye protection, gloves, and rubber shoe covering, where applicable Scrub suit, cap, gown, mask, eye protection, gloves, and rubber shoe covering, where applicable
