The two workers went down inside the septic tank installed recently at a residential house in Nababganj, but as is so often the case in their line of work, they didn't have the proper equipment with them to avoid inhaling the toxic gases found in these tanks.

Eventually they fell unconscious. Locals later rescued and took them to upazila health complex where the doctor announced them dead.
