PERMEATION TESTING OF NITRILE - COATED COTTON GLOVE (BEST NU-FANGLE #7&0/L760)
Permeation tests to compare protection against a mixture of carbon tetrachloride and perchloroethylene were conducted this month by the Louisiana Division Industrial Hygiene Group. The samples were tested by cutting a swatch from the palm of the glove so that no seams were involved, placing the samples in a test apparatus, covering the coated side of the material with 20/25 mis. of a 50:50 mixture of the solvents, and taking air samples from the chamber on the other side of the glove.

CONCLUSIONS
1. These gloves should not be considered as protection against chemicals because of their materials of construction and/or seams.
2. However, the nitrile-coated glove does offer some protection in the event of accidental chemical contact.
3. The wear characteristics and the greater suitability to a chemical plant atmosphere recommend the nitrile-impregnated glove as an excellent replacement for the cotton and vinyl-impregnated cotton gloves.
It is hoped that along with the new gloves, there will be new emphasis on proper use and choice of protective clothing.
