The effect of an alternate environment as a collection medium on the permeation characteristics of solid organics through protective glove materials.

American Industrial Hygiene Association journal·1994

Area of Science:

  • Materials Science
  • Analytical Chemistry
  • Occupational Safety

Background:

  • Glove materials are critical barriers against chemical exposure.
  • Assessing permeation characteristics of glove materials by organic solids is essential for safety.
  • Existing methods may lack precision or efficiency in evaluating solid-to-glove permeation.

Purpose of the Study:

  • To develop and validate a novel method for determining the permeation characteristics of glove materials exposed to organic solids.
  • To establish a reliable system for quantifying permeation kinetics, including breakthrough and steady-state rates.
  • To provide data for informed selection of protective glove materials.

Main Methods:

  • Utilized a stainless steel exposure cell for controlled contact between solid organic materials (disks or powders) and glove samples.
  • Employed a gas chromatograph with a flame ionization detector for sensitive detection of permeating organic solids.
  • Implemented an automated system for instrument control and data acquisition to determine key permeation parameters.

Main Results:

  • The developed method allows rapid and uniform contact, minimizing membrane bowing.
  • Achieved sensitive detection limits for organic solids ranging from 0.9 to 1.2 ng.
  • Successfully determined breakthrough times, steady-state times, and steady-state permeation rates for five glove materials against nine organic solids.

Conclusions:

  • The new method provides a robust and efficient means to evaluate glove material performance against organic solids.
  • The quantitative data generated are vital for enhancing personal protective equipment selection and chemical safety protocols.
  • This approach facilitates a better understanding of solid-to-glove permeation dynamics.
