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

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

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
