As explosions tear through the chemical facility, large plumes of smoke and toxic gas rise skyward.
Anyone caught in the blast area would either be killed or seriously injured.
With fires that could burn at 2,000 deg C, firefighters could take hours trying to get it under control.
Sending rescuers into the disaster area would also mean they could end up as casualties.
That is why the Singapore Civil Defence Force (SCDF) will be using unmanned vehicles to help fight such fires.
At yesterday's Workplan Seminar, an annual platform for the SCDF to lay out plans for the year ahead, it unveiled several new types of equipment.
The SCDF recently bought four remote-controlled unmanned fire-fighting machines (UFM), which will be deployed at different stations.
One, already stationed at Jurong Fire Station, was brought in three weeks ago, said Major Ivan Kwok, project team leader for the UFM.
While it has not been deployed to fight any fires here yet, it is already operational.
The remaining three will arrive in July and will be deployed at Jurong Island, Yishun and Changi fire stations.
The Austria-made vehicles will likely be used in high fire load situations, such as industrial or petrochemical fires where there may be a lot of combustible material, Maj Kwok said.
He added that the four fire stations were chosen because of their proximity to high risk areas and because they can best cover the whole of Singapore.
