What led to the flash fire in the Tuas sewer manhole?

Question

Accepted Answer

The Cause of the Tuas Sewer Manhole Flash Fire Remains Under Investigation

The exact cause of the flash fire that injured two employees of Hong Hock Global at a sewer manhole in Tuas on the morning of July 10 is currently under investigation by the Ministry of Manpower (MOM). While the incident occurred as workers were hacking cement around the manhole, the specific source of ignition and the nature of any flammable gases present have not yet been determined. MOM has consequently ordered a suspension of all manhole-cover replacement works by the contractor.
Workers Sustained Injuries During Cement Hacking

Two employees of Hong Hock Global sustained burn injuries on July 10 while engaged in hacking cement around a sewer manhole located near the junction of Jalan Buroh and Pioneer Road. The flash fire erupted suddenly from within the manhole during these operations. One of the injured workers has since been discharged from Singapore General Hospital, while the other remains hospitalised for observation.
Contractual Works Have Been Suspended

Following the incident, the Ministry of Manpower has issued a directive for Hong Hock Global to halt all manhole-cover replacement works. This suspension will remain in effect until the ongoing investigations can ascertain the precise cause of the flash fire and ensure that adequate safety measures are in place.
Safety Protocols Under Review

As part of the ongoing investigation and remediation process, MOM has instructed Hong Hock Global to conduct a thorough review of its existing risk assessments. The company is also required to reinforce its safety protocols to prevent future occurrences before it is permitted to resume operations involving manhole work.
Potential for Flammable Gases Acknowledged

The Ministry of Manpower has highlighted that underground infrastructure, including sewerage and waste pipes, can generate flammable gases. This underscores the general industry requirement for employers to perform comprehensive risk assessments and implement robust controls to mitigate fire and explosion hazards for their workers. Proper briefing on hazards, safe work procedures, and adequate supervision are also considered essential.
