Regulatory Suspension and Safety Review
Following the flash fire, MOM has mandated that Hong Hock Global halt all similar operations.

MOM has emphasized that employers are responsible for protecting workers against fire and explosion hazards when working on underground infrastructure. Regulations require that contractors conduct comprehensive risk assessments before any work commences. Furthermore, firms must ensure that workers are adequately briefed on the hazards and safe-work procedures, while maintaining the necessary supervision.
