In several, migrant workers travelling to their home states, or their belongings, were sprayed with a disinfectant, apparently to sanitise them. The chemical in the spray was a sodium hypochlorite solution.
Sodium hypochlorite is commonly used as a bleaching agent, and also to sanitise swimming pools.
As a common bleaching agent, sodium hypochlorite is used for a variety of cleaning and disinfecting purposes. It releases chlorine, which is a disinfectant.
The concentration of the chemical in the solution varies according to the purpose it is meant for.
A normal household bleach (for disinfecting buildings and solid surfaces) usually is a 2-10% sodium hypochlorite solution.
At a much lower 0.25-0.5%, this chemical is used to treat skin wounds like cuts or scrapes.
An even weaker solution (0.05%) is sometimes used as a handwash.
The World Health Organization, and the US Centers for Disease Control and Prevention, recommend homemade bleach solutions of about 2-10% concentration to clean hard surfaces to clear them of any presence of the novel coronavirus.
Important Info :
Sodium hypochlorite is corrosive, and is meant largely to clean hard surfaces. It is not recommended to be used on human beings, certainly not as a spray or shower.
Large quantities of chlorine can be harmful. A 1% solution can cause damage to the skin of anyone who comes in contact with it. If it gets inside the body, it can cause serious harm to lungs.
