Unit Six

Chemical Protective Clothing and Equipment (CPC&E)


Objectives l.jpg

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 l.jpg

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 l.jpg

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 l.jpg

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 l.jpg

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 l.jpg

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 l.jpg

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 l.jpg

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


Performance requirements l.jpg

Performance Requirements

  • Chemical Resistance

  • Strength

  • Flexibility

  • Thermal Limits

  • Cleanability

  • Lifetime

  • Visibility

  • Cost

B461 Course


Chemical resistance terms l.jpg

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
