MUMBAI, Nov. 18 -- A week after two sanitation workers died inside a sewage treatment plant (STP) tank in a Powai housing society, the National Commission for Safai Karamcharis (NCSK) has taken cognisance of the deaths and has asked the Mumbai Suburban Collector to file a detailed report on the incident and the action taken so far. The move follows a complaint by Pune-based lawyer Sagar Ratan Charan, who termed the incident a clear case of manual scavenging, a practice outlawed under the Prohibition of Employment as Manual Scavengers and Their Rehabilitation Act, 2013. The report must include, as per the NCSK's email, a copy of the FIR with a mention of the relevant sections of Manual Scavenging Act, 2013, assurance of a Rs.30 lakh compensation to the victims' families, over a Rs.10 lakh life insurance paid to the families. After the death of Akshay Mandal, 22, and Phulchand Kumar, 28, who went in to rescue an unconscious Mandal on Wednesday - Mandal died before reaching Hiranandani Hospital after they were rescued by the fire brigade, and Kumar later in the night at the hospital, the Powai police initially registered an ADR. On Friday, an FIR was filed against the deceased Kumar, the supervisor and owner of a private agency for not following proper safety precautions under the provisions of the Prevention of Manual Scavenging Act, 2013 on Friday. The Loktantrik Kamgar Union said both the families have been promised a compensation of Rs.15 lakh each and Rs.10 lakh from the employer, and Rs.5 lakh from the housing society, on the agreement that they would not press charges forward against either of the parties....
