Two construction workers died, and two others were hospitalized on Thursday after reportedly inhaling toxic gas from a newly built septic tank in Bera upazila of Pabna district.
The deceased were identified as Sajibul Islam, 25, son of Abul Kalam and Mostakin, 30, son of Abdul Gafur of Hatigara of Bera municipality area.
Waliur Rahman, officer-in-charge of Bera Model Police Station said the septic tank was constructed in the house of Taher Uddin around two weeks ago.
On Thursday morning, four workers fell unconscious while opening the bamboo mold of the septic tank used during roof construction.
Hearing screams, local people rushed them to Bera Upazila Health Complex, where the on-duty doctors declared two of the workers dead. The surviving two workers – Rabiul Islam and Samrat Sheikh – were taken to Pabna General Hospital.
Doctors said lack of oxygen inside the septic tank might be the reason behind the death.
