a Aldehydes: (Formaldehyde, Paraformaldehyde, Glutaraldehyde)

1. Chemical Disinfectant Groups a. Aldehydes: (Formaldehyde, Paraformaldehyde, Glutaraldehyde) Formaldehyde – and its polymerized solid paraformaldehyde have broad-spectrum biocidal activity and are both effective for surface and space decontamination. As a liquid (5% concentration), formaldehyde is an effective liquid decontaminant.

Alcohol-Based Hand Sanitizers
Alcohol-Based Hand Sanitizers

Non-alcohol-based hand sanitizers may 1) not work equally well for all classes of germs (for example, Gram-positive vs. Gram-negative bacteria, Cryptosporidium, norovirus); 2) cause germs to develop resistance to the sanitizing agent; 3) merely reduce the growth of germs rather than kill them outright, or 4) be more likely to irritate skin than alcohol-based hand sanitizers 1,2.

Baking Soda
Baking Soda

Although baking soda is often used a household cleaner, it is ineffective against most bacteria, including salmonella, E. coli. and staphylococcus. If you suspect there has been a contamination of any of these bacteria, ditch the baking soda in favor of a product registered as a disinfectant by the EPA.

Both bleach and iodophors should be made up in cold water in order to prevent breakdown of the disinfectant. c. Quaternary Ammonium Compounds: (Zephirin, CDQ, A-3) Quaternary ammonium compounds are generally odorless, colorless, nonirritating, and deodorizing. They also have some detergent action, and they are good disinfectants.

DRY HEAT
DRY HEAT

Heat is the most common physical agent used for the decontamination of pathogens. “Dry” heat, which is totally non-corrosive, is used to process many items of laboratory ware which can withstand temperatures of 160°C or higher for 2-4 hours.

e Acids/Alkalis:
e Acids/Alkalis:

Acids/Alkalis: Strong mineral acids and alkalis have disinfectant properties proportional to the extent of their dissociation in solution. Some hydroxides are more effective than would be predicted from their values. In general acids are better disinfectants than alkalis. Mode of action is attributed to an increase of H

What is water disinfection? Water disinfection means the removal, deactivation or killing of pathogenic microorganisms. Microorganisms are destroyed or deactivated, resulting in termination of growth and reproduction. When microorganisms are not removed from drinking water, drinking water usage will cause people to fall ill.

Disinfection does not necessarily kill all microorganisms, especially resistant bacterial spores; it is less effective than sterilization, which is an extreme physical and/or chemical process that kills all types of life.

Hydrogen Peroxide
Hydrogen Peroxide

Hydrogen peroxide can be used for cooling tower water disinfection, when it is combined with other disinfectants. Peracetic acid (CH 3 COOH, PAA) can also be used for cooling tower water disinfection.

Soap and Water
Soap and Water

So soap enables the water to remove dirt from your skin. It may remove bacteria from you, but it doesn't harm them. Disinfectant creates a chemical environment which is harmful to bacteria but, because you are so much larger, not to you. Disinfectant will not get dirt off your skin any better than water, but it will kill bacteria. In the absence of soap, bacteria can be protected by grease, so soap and disinfectant work together in an "I'll grab them, you hit them" way.

Is Vinegar a Disinfectant? Share With the rise of the green living movement, many moms have tried out “natural” household cleaning products promoted as effective as and healthier than chlorine bleach.

WET HEAT
WET HEAT

Dry heat is less effective than wet heat for sterilizing biohazardous materials. Dry heat requires more time (two to four hours) and a higher temperature (320–338°F or 160–170°C) to achieve sterilization. A Bacillus species biological indicator can verify dry heat sterilization.
