Gloves testing

The older technique for this purpose (Ref 8), variously referred to as the paraffin test, the paraffin-glove test, the dermal nitrate test, and the diphenylamine test, had been abundantly shown to be unreliable, was no longer accepted in most US courts, and was now seldom used by good crime investigation laboratories...

In the European Standard for protective gloves against chemicals and micro-organisms, one of the requirements is that the protective effect for a certain combination of protective glove/test chemical should be presented as protection index. Protection index is based on breakthrough time measured at constant contact with the test chemical (European Standard EN 374-1,1994) (Table 4).

The Dust Study, which is described elsewhere in the preamble, assessed the proposed work practices. As one component of the proposed work practices, the cleaning verification was evaluated in the Dust Study. It should be noted that the Dust Study was not designed specifically to evaluate the cleaning verification in isolation of the rest of the work practices. Unlike the earlier Disposable Cleaning Cloth Study that was intended to test the effectiveness of the use of the white glove test in isolation, the Dust Study was meant to evaluate the effectiveness of the proposed work practices, including cleaning verification. 

Note that various professional organizations have also developed standards which can be useful for glove testing. 

Experimentation with test animals and laboratory and plant experience indicate that the fluorophosphoric acids are less toxic and dangerous than hydrogen fluoride (58). However, they contain, or can hydrolyze to, hydrofluoric acid and must be treated with the same care as hydrofluoric acid. Rubber gloves and face shields are essential for all work with these acids, and full mbber dress is necessary for handling larger quantities. The fumes from these acids contain HF. 

Poly(tetramethylene ether) glycols were found to have low oral toxicity in animal tests. The approximate lethal oral dose, LD q, for Terathane 1000 has been found to be greater than 11,000 mg/kg (272). No adverse effects on inhalation have been observed. The polymer glycols are mild skin and eye irritants, and contact with skin, eyes, and clothing should be avoided. Goggles and gloves are recommended. In case of contact with the skin, wash thoroughly with water and soap. If swallowed, no specific intervention is indicated, because the compounds are not hazardous. However, a physician should be consulted (260). 

Unless specifically tested, all cyanocarbons should be considered as toxic as sodium cyanide or hydrogen cyanide (see Cyandes). They should be used only in a fume hood, and mbber gloves should be worn. 

A simple, quahtative method is the skin stripping technique (322) which strips off a sampling from the skin with ceUophane tape. Methods have been developed (330,331) in which organisms on the hands ate transferred to gloves and sampled. These methods assess both immediate and persistent effects of antiseptics. In aH tests with antiseptics, suitable neutralizing chemicals for the antiseptics employed are necessary so that surviving bacteria may be recovered and counted. Some of these are lecithin, Lubrol W, Polysorbate, and sodium thiosulfate (322). 

Tests have been developed that test different products for their effectiveness as a healthcare personnel handwash (327) evaluate hand disinfectants for use in surgery (333) determine the effectiveness of a surgical hand scmb, ie, the glove juice test (311,329) evaluate antiseptics for the oral cavity to be used in mouthwashes (334,335) and test antiseptics for the periurethral area and appHcation to catheters (336,337). A method used for a test comparing four antiseptic products was adopted as recommended practice by the Association of Practitioners of Infection Control (338).

It is important to emphasize that often — but not always — the performance of a product with a chemical depends heavily on the manufacturer and a specific product model. A model that performs well with one chemical may perform poorly with another chemical, even when the chemicals are in the same chemical class. This is illustrated by the Edmont Model 37-165 glove which was tested against all five acids. This glove shows good protective properties with hydrochloric, perchloric, and phosphoric acids, but exhibits degradation in nitric and sulfuric acids.
