Second Link Collision Near Tuas Sends Chemical Trailer Into Sea, No Leak Reported

Crash Near Malaysia-Singapore Border Involves Two Chemical Lorries

Two lorries collided on the Second Link bridge late Thursday, July 24, 2025, causing one chemical trailer to fall into the sea.

The crash happened at KM0.8 of the North-South Expressway’s Second Link stretch in Tanjung Kupang, near the Malaysian border checkpoint connecting to Tuas, Singapore.

The crash, reported by the New Straits Times, took place at approximately 5.41 pm and involved a red trailer loaded with propylene glycol and a white trailer transporting sodium hypochlorite.

The red trailer went over the bridge and into the sea, while the white one remained on the road and was not damaged.

Quick Response From Firefighters and Hazmat Team

Emergency teams from the Iskandar Puteri Fire and Rescue Station, together with a hazardous materials (hazmat) unit from Larkin, were sent to the scene.

They arrived within 16 minutes of being alerted.

The team, which included 13 firefighters and a Fire Rapid Tender vehicle, carried out inspections to check for any chemical leaks.

Visual checks found no leaks, foam, or bubbles on the water surface, which would have indicated a leak from the propylene glycol tank.

Both Chemical Containers Remained Sealed

Based on reports, both chemical tanks, one submerged and one still on the bridge, were intact.

Hazmat officers confirmed that there was no leakage from the submerged tank, and the sodium hypochlorite container on the white trailer was also secure.

Propylene glycol is commonly used in products like cosmetics, food additives, and pharmaceuticals. Although it is considered low in toxicity, a large spill could still harm the environment.
Sodium hypochlorite, often used as a disinfectant or bleach, must also be handled with caution. In this case, no chemical entered the sea.

One Driver Injured, Traffic Managed at the Scene

The driver of the red trailer, which plunged into the water, was later brought to the Gelang Patah Health Clinic for medical attention, while the other driver was not injured.

Traffic along the Second Link was congested following the crash but remained under control while authorities carried out their work to secure the area and monitor for any delayed chemical leakage.
