Aam Aadmi Party (AAP) MLA Raghav Chadha said the hi-tech Japanese machines were used to sanitise Rajinder Nagar area today.
"These machines from Japan are very flexible as its length is adjustable, and therefore, can easily enter narrow lanes. Ppm sodium hypochlorite solution has been used for the sanitisation drive," the Rajinder Nagar MLA was quoted by news agency ANI as saying.
According to the World Health Organisation's (WHO) sanitisation guideline, sodium hypochlorite at 0.5% (equivalent to 5000 ppm) is recommended for disinfecting surfaces. The guideline says that effective inactivation of the highly contagious coronavirus could be achieved within a minute using sodium hypochlorite, a common disinfectant.
