No disinfectant is capable of killing all germs found on a hard surface. The absence of all germs is referred to as sterilization and is a process that surpasses the efficacy level achieved with any disinfectant solution. EPA-registered chemical sterilants are the only types of sanitation products that can make a claim to kill all pathogens on hard surfaces. Before deciding on which disinfectant is right for your specific purpose, be sure to read its label. Many excellent disinfectant solutions exist that meet the needs of most applications.
When choosing, consider a few key decision-making guidelines:. Surfaces to be disinfected: Some disinfectants are not recommended for all surfaces. One example is bleach, which can be damaging to stainless steel. Another is products with a high pH, which can damage floor finishes and fabrics.
Neutral pH solutions are better on floors than high pH solutions, however they may not have all of your required kill claims. Safety and user exposure: Building occupants, students, patients, residents, and janitorial staff may have skin or odor sensitivities to various disinfectant solutions. Bacteria, viruses, and other microorganisms can hide deep in these cracks, where an application of hand sanitizer might not be thorough enough to get them.
Part of the CDC's hand-washing guide which is a process you can follow when applying hand sanitizer as well, to be thorough with its application , is making sure you give soap or hand sanitizer plenty of time to work its way deep into these cracks. The fourth reason actually has something to do with what It's not actually a flat percentage; it's measuring something called the D-value, or the " decimal reduction time " for the cleaner.
It's based on a logarithmic scale, which is some complicated math you don't really need to know to understand the system. There will always be some leftover germs, whether it's hidden in deep crevasses beneath your nails or in wrinkles in the skin, or it's just microorganisms that aren't killed by alcohol. Other than the legal liability, all of those reasons indicate that hand sanitizer simply can't kill every germ on your hands.
So, is that okay? Is that fine, or is it something you should worry about? The fact is, it's fine in almost every case. Hand sanitizer is broadly used in hospital settings for a reason, and that reason is that it's generally sufficient to prevent the spread of most diseases between patients and healthcare workers.
The hand sanitizer you get for carrying around on your daily errands might not be the same kind of hand sanitizer a hospital is using, of course. Theirs tend to have foaming agents and soaps as well as alcohol. There are also plenty of hand sanitizers that don't actually contain alcohol , or that contain a low enough concentration that it's not effective.
As with any product, it's important to get the right kind of product for the job you want it to do. A hand sanitizer that doesn't have alcohol in it can work against many types of germs, and if you're generally concerned about things like the flu, they can be fine.
If you're concerned about the pandemic — which many of us are — you need a product with plenty of alcohol, full stop. Hand sanitizer also has one major drawback, and that's the fact that you aren't rinsing your hands after using it.
You may kill most of the germs on your hands, but some remain, and even if they're bound up in dirt and grime, they're still there. Using soap and water is particularly effective; not just because soap destroys bacteria and viruses, but because it also rinses away the bound but not killed microorganisms as well. Hand sanitizers also have one other limitation, which is that they only work on your hands. For germs you pick up on contact with surfaces, that's fine.
Not all disinfectants and medical fluids are created equal. Contrary to popular belief, disinfectant solutions may differ from each other in many different ways.
They may also have different efficacy claims and dilution ratios. The most common disinfectant solutions used for facility maintenance or deep germ kill action are composed of active ingredients like sodium hypochlorite bleach , quaternary ammonium quat , hydrogen peroxide, silver ions, alcohol or acids, iodine, etc. Perfect manscaping tips for millennial men.
