SINGAPORE - A fire blazed through two double-storey factory units at Toa Payoh Industrial Park early Friday (Jan 29) morning.

The Singapore Civil Defence Force (SCDF) was alerted to the fire at 11 Toa Payoh Industrial Park at about 2.25am, which involved laundry and paper products, including cartons of boxes.

According to the SCDF Facebook page, two fire engines, three Red Rhinos, eight support vehicles and an ambulance were dispatched to the location.

About 60 firefighters were involved in the firefighting operation.

Upon arrival, the firefighters used five water jets to contain the fire, and at the height of the operation, up to seven jets were used.

Foam was also used in the firefighting, and an Unmanned Firefighting Machine and aerial appliance were also deployed.

The fire was brought under control within 90 minutes and extinguished at about 6.30am.

There were no injuries reported, and the cause of fire is still under investigation, said a SCDF spokesman.

SCDF is currently carrying out damping down operations to prevent any potential rekindle of fire from the hot burnt surfaces.

An employee of California Laundry, who gave her name as Cindy, told The Straits Times on Friday morning that she heard the fire started from a neighbouring shophouse that does printing and box packaging.

"Heard there was a fire last night, with mention of laundry and paper. Then it turned out to be where I work."

Another California Laundry employee Madam Saroja Devi, 68, said: "I came to work but saw all my friends standing outside. We were very shocked to see the SCDF and the smoke."

As of 10am on Friday morning (Jan 29), at least one small fire could be seen burning inside one of the shophouses while the SCDF continued their damping down operations.

The fire swept through both printing and paper packaging company Jetwind Printing and Packaging, and California Laundry services.

Employees said they did not know what had happened.

"I arrived here for work and saw the cordon and the smoke, and was quite shocked," said Jetwind salesman Mr James Tan, 35.

The fire caused quite a stir at the residential blocks across the road from the industrial area.

Madam Jessie Hung, who is in her 70s, said she heard "many voices" at 5am, and that there was quite a bit of commotion.

"You know there's something wrong when there's noise and a crowd so early in the morning," said the retired cleaner.

Another resident, Ms Adeline C, 40, said she was awoken by crackling noises and the reflection of siren lights on her bedroom wall.

"There were no explosions or loud noises, but a sort of crackling," said Ms C, who works in sales.

"I went outside to see, and the smoke was quite high. There were other neighbours who came out to the corridor too, and we stayed and looked until 6am," she said.
