Safety lapses cited in deaths of two workers from toxic gas exposure
A workplace inspector has testified that two workers who died after inhaling hydrogen sulphide at a water treatment facility in May 2024 were not wearing proper respiratory protection and failed to follow established safety procedures.

The two workers, Mr Srinivasan Sivaraman and Mr Izzat Naqiuddin Dowod, succumbed to exposure to hydrogen sulphide, a hazardous by-product generated during water treatment operations. Evidence presented by the inspector revealed critical gaps in safety compliance at the facility where the incident occurred.
Testimony indicated that the workers lacked appropriate respirators at the time of exposure, a fundamental requirement for personnel working in environments where toxic gases may be present. Additionally, the inspector's account highlighted deviations from standard safety protocols that should have been in place to prevent such incidents.
The case underscores persistent concerns about workplace safety standards in industrial facilities across the region. Hydrogen sulphide is a highly toxic gas that can cause rapid incapacitation and death even in relatively low concentrations, making proper protective equipment and adherence to safety procedures essential for worker survival.
The findings suggest systemic failures in safety management at the facility, raising questions about oversight and enforcement of occupational health standards. Authorities are expected to determine whether additional measures or penalties are warranted in response to the lapses identified during the investigation.
