To be sure, the availability of hand sanitizer should be predicated on ease of use, such as putting dispensers where they will be recognized and used.

“Using soap and water is the most desirable aspect for hand washing, but we are not always around soap and water, and that’s why it’s important to have hand sanitizer as a supplement,” says Brian Sansoni, vice president of communications for the American Cleaning Institute, Washington D.C.

The decision for the placement of hand sanitizer dispensers should also take into account the kind of dirt to be washed off of hands.

“The CDC says that you use hand sanitizer when you don’t have any visible dirt on your hands,” says Beatrix Babcock, a partner for HCI Consulting Group LLC in Denver.

However, it can be challenging to find a location that maximizes occupant visibility while adhering to building safety codes.

“Hand sanitizers are alcohol-based and the [National Fire Protection Association 101] Life Safety Code prohibits some places you can put them,” says Babcock. “You can’t put them near electrical outlets, and most hospitals have taken them out of the hallways, especially in government hospitals, because of the high amount of alcohol in them.”

So where are some of the best places to position sanitizer dispensers?

“It’s wise to have it in places where there is high traffic depending on what kind of public setting you’re in,” says Sansoni. “Places where there are lots of meetings going on, office buildings, conference rooms or auditoriums, are great places to have hand sanitizer dispensers. Having them in a place where there’s lots of foot traffic is a great way to keep the hands clean.”

Hand sanitizer is also showing up more frequently in hospitals, schools, hotels, shopping plazas, and even grocery stores.

Many hospitals are now placing dispensers next to check-in desks, medication carts, nurse’s stations, outside patient rooms, and inside patient rooms next to soap dispensers.

Grocery stores, in particular, have been forward thinking when it comes to hand sanitizer availability for their customers. Retailers place them next to carts right as customers walk in, says Fletcher Ostrander, partner for E-Z Way Products LLP, a Waterbury, Conn.-based distributor. Hand sanitizer dispensers also pair well with wet wipes to clean off cart handles, he adds.

“Those dispensers certainly send a message that the retailer cares about its shoppers, customers, and employees, as well,” says Sansoni. “Hopefully the stores have enough sanitizer in back offices and food handling areas. Having these sanitizer dispensers available in grocery stores not only sends a positive message to shoppers, it’s an extra tool to enhance public health.”

In any facility, people may not properly wash their hands after using a restroom, so having hand sanitizer placed inside the restroom or just outside a restroom door may be a useful reminder, says Sansoni.

People exiting the restroom may also want to use hand sanitizer after touching the restroom door, says Sansoni. Even though users just washed their hands, touching the restroom door upon exiting could re-contaminate hands.
