Unit Six

Chemical Protective Clothing and Equipment (CPC&E)

objectives
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

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

classification components
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

epa levels of protection
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

level a protection
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

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

B461 Course

level c protection
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

level d protection
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

performance requirements
Performance Requirements
  • Chemical Resistance
  • Strength
  • Flexibility
  • Thermal Limits
  • Cleanability
  • Lifetime
  • Visibility
  • Cost

B461 Course

chemical resistance terms
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
