Nano Silver-Titanium Technology

Image of TubestationA recent article in the Evening Standard prompted concerns from some of our Chemical Sensitivity sufferers. Main line and Tube trains and stations could be sprayed with a powerful new anti-flu disinfectant, it revealed.

Nano Silver-Titanium Dioxide coating (NSTDC) is a non-toxic disinfectant, which has been certified as effective in killing a wide range of bacteria, viruses and mould including the H1N1 flu virus. This is being introduced on the Hong Kong metro rail system by the MTR Company. The special nano coating will be applied to all surfaces touched by its daily 2.5 million commuters in Hong Kong such as escalator handrails, the buttons on ticket issuing machines etc. and is now being considered for the underground trains in the UK. 

We asked our Chemical sensitivity expert John Collard for his views on the subject, this is his reply:-

"This is about the safest possible way of disinfecting; far safer than the bleaches etc that are used at the moment.  I think the risk of a chemical sensitivity sufferer being affected is very small; they are going to have much greater problems with the perfumes, formaldehyde etc present on the other passengers.

The only problem might be whatever solvent is used in the spray, but this will quickly disappear and as each train is only sprayed about once every 3 years you would be extremely unlucky to catch one that had been sprayed in the previous couple of days."

Good News!
