A truck carrying nitric acid overturned near the Bang Bua Thong interchange, emitting hazardous vapours and prompting an emergency response.

 

The six-wheeled chemical transport truck driver, lost control and overturned on the Western Ring Road, along the elevated Highway 345, while heading towards Pathum Thani on the morning of 21st February. The crash resulted in a leak of nitric acid, releasing thick orange fumes and a sharp, pungent odour that spread across the roadway.

 

Emergency services were alerted at approximately 09:45 and dispatched firefighters from Lahan Municipality along with specialist rescue teams to contain the spill. Concerned motorists reported the fumes seeping into their vehicles, prompting authorities to close the affected section of the road to prevent further exposure.

 

The overturned vehicle, a Hino box truck registered in Nakhon Pathom, had been transporting four 1,000-litre containers of nitric acid from Samut Sakhon to Pathum Thani. The impact of the crash caused one of the containers to rupture, with the acid corroding the truck’s metal frame and releasing the orange vapours.

Firefighters used water spray to suppress the vapours and prevent further hazards before removing the damaged truck and its remaining chemical cargo. The operation was completed without any reported injuries.

 

Authorities are now investigating the cause of the crash and reviewing safety measures for the transportation of hazardous materials.

My initial thoughts are should hazardous substances be transported in vehicles that are clearly in a state of disrepair and without proper hazardous goods markings?

 

Answers on a postcard.

Looks like fallen over in curve i.e too high speed.

 

Driver probably assumed gravity does not apply to whatever he thought he was transporting. 

 

Or never heard of gravity in the first place.
