On another public health front, we had only about 16 sinks for hand washing. These were in the four bathrooms that were in the shelter. Port-a-Pottys were outside, but they had no hand washing stations. We started an aggressive campaign of distribution of giant bottles of hand sanitizer. Hand sanitizing stations were...

In the last 30 years the types and forms of antimicrobial products have evolved and now include bar soaps, liquid soaps, lotions, hand dips, hand sanitizers, foams, and rub products. In the United States the importance and need for antimicrobial products was recognized by an expert panel convened by the Food and Drug Administration (FDA) in 1972, and in two Tentative Final Monographs... 

Alcohols have become ever more accepted as the primary skin antiseptic for healthcare personnel hand sanitizer applications in both North America and Europe [1,2], Additionally, alcohol-based hand sanitizers are well accepted for use in degerming the hands of food servers/handlers and consumers at large [3], Use of alcohols for sanitation is not new, and those containing 60-70% ethanol or isopropanol have been used for years as hand antiseptics in both the medical and food-handling environments. 

Additionally, in a survey overview on the effectiveness of handwashing and hand disinfection for the removal of nosocomial pathogens from heavily contaminated hands, 0.5% CHG in 70% isopropanol was most effective, followed by 70% ethanol and, to a lesser extent, 40% isopropanol [5], Comparison of the efficacy of 62% ethanol, 70% isopropanol, and benzylalkonium chloride-based hand sanitizers using the healthcare personnel handwash protocol indicated that all three had equivalent efficacy at greater than 2-log reduction after the first wash, whereas the benzylalkonium chloride hand sanitizer demonstrated residual efficacy. 

Immediate antimicrobial effectiveness depends upon the amount of the antimicrobial hand sanitizer used, the type used, the amount of time spent washing the hands, the mechanical pressure and friction exerted in the wash, and the temperature of the water. Even when a very effective handwash regimen has been developed, healthcare personnel must comply with the wash regimen for it to be successful. 

Ambidextrous disposable polyethylene gloves were used throughout the studies. Hand cleansing and sanitization were carried out using an antibacterial lotion soap and an alcohol (gel) hand sanitizer. Ground beef, buns, vegetables, and paper wrap were used in the simulated food handling. 

Test Configuration 8 (bare hands/hourly washing and sanitizing). Subjects washed their hands with the assigned antimicrobial soap followed by a hand sanitizer application immediately before beginning the simulated food service tasks (time 0), as well as hours 1, 2, and 3. A baseline (premarker bacteria exposure) sample of the hands as well as sampling at the end of the test period were conducted. 

The choice of and compliance with an effective regimen is essential for food protection. It is clear that a policy where gloves are employed to provide no bare-hand contact with ready-to-eat food is not a panacea and may only serve to provide a dangerous, false sense of security. Caution should be exercised in the selection of the most effective regimen for food protection. Additional studies should be conducted in food industry settings to validate the most effective regimen of hand sanitization for food protection. 

The type of product form to be evaluated in the HCPHWT can affect the outcome of the test. The HCPHWT was specifically designed to evaluate traditional rinse-off products for healthcare workers. This method may not be appropriate for other types of hand cleaners. Alternative products to soap and water such as hand sanitizers and towelettes are being marketed to consumers. These product forms are generally used when soap and water are not available. The appropriate way to evaluate the efficacy of leave-on alternative hand hygiene products is being debated. The European community is recommending the CEN... 

More research needs to be performed to better understand consumers typical intervention points after contact with the environment. Unlike the healthcare setting, in which healthcare workers contact contaminated sources such as a patients and should wash their hands, consumers generally wash their hands only when they perceive them as being dirty. Consumers need to be better educated about how they can contact bacteria and when they should wash their hands. Many consumers may not wash their hands frequently enough to significantly reduce risk of bacterial transfer or infection. Increased use of antimicrobial products with persistent activity could reduce risk of contamination especially in situations where frequent handwashing is not practical or the use of alternative forms such as hand sanitizers allow for washing away from sinks.

Topical antimicrobial handwashes and hand sanitization are very important in the food service industry. Important, also, is gloving. Chapter 19 addresses gloving and handwashing, and Chapter 20 provides research data from various studies. Chapter 21 discusses quality assurance issues, and Chapter 22 offers another perspective on the wash/glove controversy.

The active ingredient in hand sanitizer is usually em edcohol like isopropanol. This chemical is also used in antiseptic wipes and pads because of its ability to kill bacteria, fungi, and viruses. 

The patient assistive devices classification includes items such as walkers, bedpans, prosthetic limbs, canes, robotics, trapeze bars, wheelchair, orthot-ics (i.e., braces and shoes), patient transfer devices, and stand assist lifts. The six items belonging to the nurse protective devices classification are gloves, face masks, patient transfer devices, hand sanitizer dispensers, mechanical lifts, and gowns. The pahent protective devices classification includes items such as listed below [4] ... 

Alcohol-based hand sanitizers— A gel or rub that contains alcohol to reduce the number of viable microorganisms on the hands (60%-95% ethanol or isopropanol). 

In all I I establishments, all employees are required to wash their hands after using the toilet. Although using warm water removes most bacteria, use of soaps and especially antibacterial soaps ensure bacteria-free hands when they return to work. Liquid hand soaps currently used in I I establishments are regular hand soap, antimicrobial hand soaps, and hand sanitizer.

Environmental concerns and local regulations often dictate the use of specific sanitizers in a particular geographic location. Owing to safety concerns, the use of formaldehyde in USA has declined, in contrast to Europe, where formaldehyde and glyoxal are widely used in formulations for hard surface care products and hospital instrument disinfection. Alcohol sanitizers are primarily used in waterless hand wipes, and hand sanitizers and disinfectants. The antimicrobial action wears off when the volatile alcohol evaporates from hands or substrates. Alcohol sanitizers are not strong biocides. The most commonly used alcohol as a disinfectant is pine oil that is obtained from pitch soaking of pinewoodby steam distillation or solvent extraction. It consists mainly of isomeric tertiary and secondary, cyclic terpene alcohol, and has a turpentine-like odor. Pine sol is predominantly used in household consumer products.
