New Delhi, Jan 8: In yet another tragic incident, three sanitation workers died due to asphyxiation while cleaning a sewage treatment plant in Bengaluru. Preliminary report stated that an apartment association had hired a private contractor to clean the manhole after a blockage was reported.

The contractor had sent a team of workers to clean the manhole and during the cleaning process one worker entered the 10-ft deep manhole and slipped. Two more workers entered the manhole to rescue him but they too met with the same fate.

All the three workers reportedly struck by some poisonous gas inside the manhole and collapsed due to suffocation. Police and fire service officials reached the spot immediately and recovered the bodies of all three workers.

Expressing disappointment over the incident, Mayor R Sampath Raj said that despite so many equipments being available for the sewage treatment, people are still using labourers.
