Summary
This study examined acetone permeation through latex neoprene gloves. Thinner glove areas like the back and palm showed faster chemical breakthrough times, making them suitable for testing.
Area of Science:
- Materials Science
- Occupational Health
- Chemical Engineering
Background:
- Latex neoprene gloves are commonly used for chemical protection.
- Understanding chemical permeation is crucial for ensuring worker safety.
- Acetone is a widely used solvent with known permeation potential.
Purpose of the Study:
- To investigate the chemical permeation of acetone through latex neoprene gloves.
- To determine breakthrough times and steady-state concentrations at various glove sites.
- To identify optimal glove areas for permeation testing.
Main Methods:
- Monitoring of 23 specific sites on latex neoprene gloves.
- Measurement of breakthrough time for acetone permeation.
- Determination of challenge liquid concentration at steady-state.
Main Results:
- Thinner glove regions (backs, palms, finger interstices) had shorter breakthrough times.
- Thicker glove regions (fingertips) demonstrated longer breakthrough times.
- Higher steady-state concentrations were observed in thinner glove areas.
Conclusions:
- Glove thickness significantly impacts acetone permeation.
- The backs or palms of latex neoprene gloves are suitable for chemical permeation testing.
- Findings inform material selection and safety protocols for handling acetone.
