A JOINT chemical release emergency response exercise will take place at the Second Crossing at Tuas on Wednesday to test the operational effectiveness of the plan.

The exercise will be held from 9am to 1pm, during which only one lane on each side of the crossing will be open to normal traffic from both sides of the checkpoints.

It is the sixth exercise to be conducted to test the Emergency Response Plan, which was jointly developed by the Singapore's National Environment Agency (NEA) and the Johor's Department of Environment, under the Malaysia-Singapore Joint Committee on the Environment.

It deals with potential accidents involving the transportation of hazardous chemicals on the Second Crossing at Tuas.

NEA advised motorists not to be alarmed and to follow the Traffic Police directions at the site.

As traffic flow may be affected, motorists are advised to stay clear of the Tuas checkpoint from 9am to 1pm, to avoid any inconvenience caused by traffic congestion.
