Some chemical disinfectants are harmful to environmental surfaces, such that damage may render items uncleanable and shorten their life-span. Therefore, replacement costs need to be added to the cost of disinfectant usage. Some chemical disinfectants, including alcohols, are known to harden plastic and crack rubber.
Some of the chemical disinfectants are irritating to the skin, eyes, and respiratory system. The highly corrosive disinfectants could inflict serious damage if they come into contact with the skin or eyes. The airborne disinfectants would also cause respiratory problems if used in poorly ventilated areas.
Accidents or incorrect use of household chemical products may cause immediate health effects, such as skin or eye irritation or burns, or poisoning. There can also be longer-term health effects from chemicals.
Most chemical disinfectants readily inactivate vegetative bacteria (gram-positive, gram-negative) and enveloped viruses. Fungal spores and non-enveloped viruses are generally less susceptible.
Chemical Disinfection. Disinfection is a process that reduces the number of microorganisms present to a level at which they do not present a risk. Disinfection differs to sterilisation whereby the object is free of all viable microorganisms.
Disinfectants damage the environment
Some chemical disinfectants, including alcohols, are known to harden plastic and crack rubber. Chlorine can also damage the environment (Rutala and Weber, 2013a).
Hypochlorites, the most widely used of the chlorine disinfectants, are available as liquid (e.g., sodium hypochlorite) or solid (e.g., calcium hypochlorite).
When should disinfectants be used? Disinfectants are usually only necessary if a surface that has already been cleaned with detergent and water is suspected or known to have been contaminated by multi-resistant organisms and/or other potentially infectious material including blood and other bodily fluids.
There are several limitations with liquid chemical sterilization. Although the rinse water is treated to minimize any bioburden, it is not sterile. Because the rinse water is not sterile, devices rinsed with this water cannot be assured to be sterile.
The disadvantage of some disinfection techniques - possibly in combination – is that they produce toxic by-products. Extra measures must be taken to prevent these by-products from forming or to eliminate them. New techniques include ionising radiation (electron beam), plasma technology and “pulsed electric fields”.
a condition or situation that causes problems, especially one that causes something or someone to be less successful than other things or people: One disadvantage of living in the town is the lack of safe places for children to play.
Disadvantages of Chemical Control Methods:
Chemical pesticides are highly toxic and can cause health issues to any living organisms in contact with it. Chemical pesticides leave residue everywhere. In the case of plants, they may cause plant diseases or kill beneficial insects.
Chlorine is the universal disinfectant, active against all microorganisms. It is generally served in the form of sodium hypochlorite, with different concentrations of free chlorine. As a general disinfectant for all types of laboratory work, a concentration of 1 g/l (1000 ppm) of free chlorine is used.
We do not recommend directly breathing in Lysol products, which would likely happen if you spray Lysol on a face mask and do not wash it immediately after. Alternatively, you can use Lysol Laundry Sanitizer in pre-soak to disinfect your face mask.
VOCs and other chemicals released when using cleaning supplies contribute to chronic respiratory problems, allergic reactions and headaches.
These chemicals are all necessary for life on earth. Not all chemicals are good news, however. Some chemicals can be detrimental to the environment and human health. It all depends on the chemical's properties, uses, concentration, and interactions with other chemicals in its environment.
Sterilising with chemicals: chemical disinfection is a highly effective way of eliminating harmful germs and pathogenic micro-organisms, fungi or spores using specially formulated cleaning agents. This cleaning method is ideal for effectively and reliably disinfecting surfaces exposed to a high level of bacteria.
Clean the surface with soap and water first. Always read the label of disinfecting products to make sure the products can be used on the type of surface you are disinfecting (such as a hard or soft surface).
Wear protective gloves and other clothing when using disinfectants to reduce skin exposure. You may be familiar with the products you're using, but always check the label. You may need special eye, breathing, or skin protection.
The following disinfectants are likely to cause asth- ma: formaldehyde, glutaraldehyde, quaternary am- monium compounds, chlorhexidine and alkyla- mines. Cases of asthma often occur in workers performing disinfection tasks where the product is applied by spraying [4].
"Intermediate-level disinfection kills mycobacteria, most viruses, and bacteria with a chemical germicide registered as a 'tuberculocide' by the Environmental Protection Agency. Low-level disinfection kills some viruses and bacteria with a chemical germicide registered as a hospital disinfectant by the EPA."
The most commonly used chemicals as primary disinfectants are chlorine, chlorine dioxide, and ozone. Among them, Chlorine is the most widely used primary disinfectant throughout the world.
Contact time refers to the length of time an implement or surface must stay moist with disinfectant to be effective against pathogens (bacteria, virus, fungus) listed on the label. For BARBICIDE® and BARBICIDE® TB, the contact time is 10 minutes of moist contact to be effective.
