High concentrations of sodium hypochlorite constitute a health risk: PGIMER
The use of a “disinfectant tunnel”, in which sodium hypochlorite is sprayed to prevent the spread of COVID-19, may give a false sense of security and cause harmful side effects, the Postgraduate Institute of Medical Education and Research (PGIMER).
The use of these tunnels may give a false sense of security and may have adverse health effects as sodium hypochlorite has a lot of harmful effects on the human body.
Although a 0.5% solution of hypochlorite, which is known as ‘Dakin solution’, is used for disinfecting areas contaminated with bodily fluids, including large blood spills, however, higher concentrations of sodium hypochlorite (5%) exposure may cause nasal and ocular irritation, sore throat and coughing.
Exposure to stronger concentration (10-15%) of hypochlorite can cause serious damage to multiple organs, including burning pain, redness, swelling and blisters, damage to the respiratory tract as well as the oesophagus, serious eye damage, stomach ache, a burning sensation, diarrhoea and vomiting.
