SINGAPORE – Experts have warned against the use of disinfectant tunnels that many countries, including Singapore, are setting up to spray on people as they enter certain premises.
The idea is for people to walk through these tunnels or chambers and be disinfected to reduce the risk of them spreading Covid-19.
However, the experts say these tunnels not only do not help to curb the spread of the coronavirus, but could also cause harm to people using them.
A report in the British-based Occupational Medicine journal warned: “A chemical may be safe when applied topically in liquid form, but extremely toxic when atomised and inhaled.”
It studied a range of nine disinfectants commonly used in such tunnels, and said: “Direct aerosol contact with the cornea can cause irritation and irreversible damage. Skin irritation and damage are also common.”
