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.
ASTM: develop standard practice
ISEA Hand Protection Group: update
ICS Laboratories Inc: contractor
IPP Inc.: reviewed proposal
ISEA and manufacturers
Protective clothing users
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.
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).
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).
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.
