Question 1

Why should bioaccumulation of disinfectants matter to frontline staff?

David Hagelthorn · Accepted Answer

Bioaccumulation means the gradual accumulation of substances (eg disinfectant chemiclas, heavy metals) in an organism, typically vital organs for humans. It can happen through skin, inhalation and digestion, which in turn can cause reproductive issues, asthma, allergies, skin irritations and so on. Front line clinical staff who use disinfectants several times per day need to be aware of the issue. Further reading:

Question 2

Why should ‘reproductive toxicity’ in disinfectants matter to frontline staff?

David Hagelthorn · Accepted Answer

Reproductive toxicity means having an effect on any of the components of reproduction (eggs, sperm) as well as the pregnancy process itself. The US government’s CDC states: ‘Working with chemical disinfectants and sterilants…during pregnancy could increase your chances of having a miscarriage or preterm birth.’ CHL’s range of products do not affect any of the components of reproduction, yet are highly effective at killing pathogens. All of this info should be available on the SDS (safety data sheet) of a reputable product. Further reading:

Question 3

Why should ‘mutagenicity’ in disinfectants matter to frontline staff?

David Hagelthorn · Accepted Answer

Mutagenicity means changing the DNA of a living cell. Most traditional disinfectants will affect the DNA of the cells in your body. By contrast, CHL’s range of products will not affect the DNA in your cells (even when undiluted) , yet are highly effective at killing pathogens. All of this info should be available on the SDS (safety data sheet) of a reputable product Further reading: Mutagenicity in a molecule- Hsu et al. PLoS one ‘16

Question 4

Why should ‘cytotoxicity’ in disinfectants matter to frontline staff?

David Hagelthorn · Accepted Answer

Cytotoxicity means poisonous to cells. Most traditional disinfectants are poisonous to all loving organisms, including human cells. By contrast, CHL’s range of productrs are NOT toxic to human cells (even when undiluted), yet are highly effective at killing pathogens (bacteria, viruses etc). All of this info should be available on the SDS (safety data sheet) of a reputable product. Further reading:

Question 5

Why do I need to test for bacteria in my RO purified water?

David Hagelthorn · Accepted Answer

All purified water (inc RO water) is susceptible to bacterial growth. As the purified water is used in dental chair waterlines, this needs to be bacteria free to avoid further microbiological issues further downstream. CHL has developed a unique system to monitor and mitigate for bacteria in your RO water, so as to prevent microbiological issues manifesting in your waterlines. In addition, CQC inspections can ask what systems you have in place to monitor purified water in your dental practice- the Eau Flow RO can help you keep compliant with that request. Further reading:
