Handwashes

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).

Hepatitis E is similar to hepatitis A in that the mode of transmission is via the fecal-oral route. Therefore, the most effective ways to prevent acquiring the virus are good personal hygiene and proper disposal of sanitary waste. Frequent handwashing and avoiding contaminated foods and vegetables decrease the risk of infection. 

The chlorpyrifos reference standard was used in conjunction with the analysis of coverall dosimeter sections (arms, legs, torso), air tubes, Gelman filters, head patches, and handwashes, while the 3,5,6-TCP was used as the reference standard during urine analysis. 

Field fortifications were prepared to check the field/storage stability of the dermal dosimeters, handwashes, and air filters. The field fortifications were prepared using the formulated product undiluted for "high" level spikes and diluted with water (-1 pg/mL chlorpyrifos) for the "low" level field spikes. Field fortification solutions for urine were prepared from a 3,5,6-TCP standard in acetonitrile utilizing an 1.2-pg/mL solution for the "high" field fortifications and an -0.01-ug/mL solution for the "low" level fortifications. 

Head, neck, and hand exposures were measured using methods outlined in the literature.4 Head patches were used to estimate dermal exposure to the neck and face of the worker. Handwashes were conducted using a 0.008% DSS solution and collected in 2-L Pyrex bowls. The handwash was repeated with distilled water, and the two handwash solutions were combined. The pooled handwash was then partitioned with ethyl acetate to remove the chlorpyrifos from the aqueous phase. An aliquot of the ethyl acetate was shipped to the analytical laboratory for analysis of chlorpyrifos. 

Add to this value the micrograms chlorpyrifos found in the handwash and head patches (corrected for surface area of the head and neck). This sum in terms of ug/kg body weight per day represents the total dermal exposure (TDE).

Table 4 presents the amounts of chlorpyrifos used to fortify the various substrates in this study. Chlorpyrifos "low" spike levels for coverall sections (arms, legs, and torso) as well as t-shirts and briefs, handwashes, and head patches ranged from 5.1 pg to 1198 pg. "High" spike levels of these substrates ranged form 1456 pg to 191,720 pg. Air tubes and Gelman filters were fortified with only "low" amounts of chlorpyrifos which ranged from 0.1 pg to 36 pg.

Research on the selective effects of antibiotic soaps on bacteria are not yet far advanced, but initial evidence suggests that they are used far too frequently, with the possible risk of producing infections resistant to the best available antibiotics.
