Method of Testing the Penetration of Acid Solutions Through Safety Gloves

Liwkowicz J., Kowalska J.

International Journal of Occupational Safety and Ergonomics

Vol. 6, No. 1

81--88

Because they cause burns that are difficult to heal, acids are dangerous, and steps should be taken to ensure that the human skin does not come into contact with them. For this purpose safety gloves are generally used by workers who have to handle acids. Such gloves need to be tested to ensure that they are acid resistant. Standard EN 374 (European Committee for Standardization [CEN], 1993c) specifies a method of testing the permeation of liquid chemicals, on a molecular level, through glove material, but it may be difficult to ensure the fitness of the joints of a 4wo-compartment cell, when gloves are lined with jersey. To deal with this a simple pH-meter method to test the permeation of acid and alkali solutions through safety gloves has been developed. The permeation of H2S 0 4, HCI, HN03, and CH3COOH through gloves made from neoprene, nitrile, and PVC was tested. This method seems to be simple and economical.
