Degradation and Decontamination Efficacy of Chemical Protective Clothing (CPC)-FY06

NOTE: This page is archived for historical purposes and is no longer being maintained or updated.
Current Information can be found at: Degradation and Decontamination Efficacy of Chemical Protective Clothing (CPC)-FY07

Objective

  • To develop suitable methods and procedures for decontaminating and extending the useful life of CPC
  • To develop test criteria for evaluating decontamination efficacy of CPC
  • To provide users with guidelines for reuse, retirement, and disposal of protective clothing.

Applicable Standards

  • ASTM F23.30
  • ANSI/ISEA 105-2000

Key Partners

  • ASTM: develop standard practice
  • ISEA Hand Protection Group: update project progress
  • ICS Laboratories Inc: contractor
  • IPP Inc.: reviewed proposal

Stakeholders

  • ASTM
  • ISEA and manufacturers
  • Protective clothing users
Presentation meeting

Project Scope

  • Conduct permeation testing of 7 commonly used CPC materials against 12 ASTM-selected liquid chemicals (ASTM F 1001-99a), resulting in 26 combinations.
  • Investigate changes in each permeation parameter after repeated cycles of exposure/decontaminations for the 26 combinations through a contract with ICS.
  • Conduct stakeholder review, NIOSH internal review, and prepare external peer-review for "Permeation Calculator" software.

Milestones

  • Completed investigating changes in each permeation parameter for 14 of the 26 combinations (10/05 - 4/06).
  • Registered ASTM work item for the permeation calculator in F23.30: "Standard Practice for Permeation Testing Data Analysis by Use of a Computer Program" (10/3/05).
  • Submit a research proposal for determination of changes in tensile properties of the 26 combinations (09/30/06).

Outputs

  • Published 2 peer-reviewed papers, another in press
  • Developed "Guideline for the Decontamination of Chemical Protective Clothing and Equipment" published by AIHA Press
  • A provisional patent application has been filed by CDC for the "Permeation Calculator" software (7/22/05) and the invention is available for commercial licensing (Federal Register 3/08/06).
  • ASTM-approved the prospectus of the standard practice for permeation testing data analysis by use of the computer program (work item # 9186).

Outcomes

  • The health of American workers that rely on the CPC and gloves will be improved by having the decontamination guideline to ensure user safety;
  • A total of 59 copies of the decontamination guideline has been sold since it was published five months ago.
  • ASTM intended to propose cumulative permeation to be a new end-point instead of breakthrough time. It faces a technical barrier in calculating the cumulative permeation since the calculations involve an integration the permeation curve. The "Permeation Calculator" makes this possible.
