Cotton glove liners
Chemically resistant laboratory gloves come in a variety of materials such as natural rubber or latex, butyl rubber, polychloroprene, nitrile, polyethylene, PVC etc. Sometimes in combination and in differing glove thickness and glove style. Each material protects well against certain chemicals but poorly against others. The choice of material and its thickness depends on its resistance to permeation taking into account the factors listed above: - commonly, manufacturers′ literature and performance tables have to be consulted to find this information.
Some Rules for Glove Use:
Select gloves which are resistant to the chemicals you may be exposed to. Consult the relevant Safety Data Sheet (SDS) that may recommend a particular glove material.
Select gloves of the correct size and fitting; gloves that are too small are uncomfortable and may tear whereas overlarge gloves may interfere with dexterity. In some cases, such as use of HF, it may be advisable to select gloves that can be removed very rapidly in an emergency.
Before use, check gloves for physical damage such as tears or pin- holes and for previous chemical damage: this is especially important when dealing with dangerous materials such as HF.
When working, it may be advisable to wash the external surface of the gloves frequently with water.
Some gloves, especially lightweight disposables, may be flammable: keep hands well away from naked flames or other high temperature heat sources. When removing gloves, do so in a way that avoids the contaminated exterior contacting the skin.
- Wash hands after removing gloves.
- Dispose of contaminated gloves properly.
- Do not attempt to re-use disposable gloves.
- Never wear possibly contaminated gloves outside of the laboratory or to handle telephones, computer keyboards, etc.
