"Company fined S$220,000 after three workers hurt in underground tank accident", 14 August 2019 

A company called Environmental Landscape was fined S$220,000 on Wednesday (Aug 14) after an explosion in an underground storage tank left three workers with burn injuries, said the Ministry of Manpower (MOM)...

MOM's investigations revealed that Environmental Landscape had failed to conduct any risk assessment for the activities related to the cleaning of the confined space.

Critical hazards such as the presence of toxic or flammable gases were neither identified nor addressed before the workers entered the space to carry out work. 

MOM added that all four workers were not trained to work within a confined space and neither were they informed of the risks involved, such as oxygen deficiency and the build-up of flammable or toxic gases... 

The company had also failed to inform the workers of the safety precautions that should have been taken, and did not develop and implement procedures for dealing with emergencies that might arise while its employees were at work in a confined space.

In connection with the incident, Hossan was also charged for instructing the workers to perform the cleaning works without ensuring that it was safe to do so.
