Emergency services including police, Fire and Rescue NSW, Rural Fire Service (RFS), the HAZMAT 280 unit from Dubbo, ambulance and RMS personnel attended the incident, four kilometres from Parkes.

A second spill was later detected in Dalton Street.

Police report that at approximately 4.20pm the driver of a pan-tech truck was travelling east when several 200 litre drums of chemicals including Creosote fell from the rear of the vehicle. 

The driver of the truck was attempting to clean the spill as Police arrived on the scene. 

When approaching the truck, the two officers detected a strong chemical smell and accompanied the driver from the immediate area. 

The Henry Parkes Way was closed between Parkes and Manildra with traffic control crews diverting traffic via Eugowra. 

Another Creosote chemical spill was detected about 5.45pm in Dalton Street and it is believed the same truck was responsible prior to the Orange Road incident.

Forbes Fire Brigade attended to this spill. 

Approximately 30 litres of chemical were  lost – the majority of which occurred during the second spill. 

The two police officers along with the driver of the truck were decontaminated by Fire and Rescue NSW before being transported to the Parkes Hospital as a precautionary measure. 

Police investigations are continuing as well as an investigation by the Environment Protection Authority.
