Ammonia tanker stuck up under flyover, valve damage, 5 deaths, 140 injured near Ludhiana

In an incident of liquefied ammonia tanker driver trying to go through under a flyover, at 11.00 PM, the lid and the valves at the top got damaged, causing release of ammonia affecting several persons nearby.

5 persons died and 156 got injured in the incident.

It appears that there are no warning signs or no height barriers to prevent overheight vehicles going under the flyover.

The tanker was carrying 22 T of anhydrous ammonia.

Police and fire brigade officials reached the spot to control the situation. 

Some of the affected had breathlessness, eye irritation, choked voice, etc. Few had bleeding from mouth and nose.

A senior police official and others controlling the situation were also affected in the incident as per the reports.

Tanker was moved to a vacant plot.  

Ammonia solubility in water is very high and is instantaneous at temperatures below atmospheric. Water was used to absorb leaking ammonia.

The odour was present for more than eight hours. The affected areas was about four kilometer radius around.

Dead animals/birds and vegetation/plants were seen.

Heavy rain later subsided ammonia in the environment by absorbing and washing.

A case was registered under Sec 304 of IPC (culpable homicide not amounting to murder) on the absconding driver.

Ammonia reactor blast - 10 persons injured

As per news reports, a brine unit chiller with ammonia exploded on Saturday i.e 28.06.2014, leading to ammonia leak, injuring 10 persons with burns. As per some other reports, 11 persons got injured in the incident. Persons suffered suffocation, breathlessness and giddiness.
To clear the choking of brine in the chilling unit, steam was admitted which led to expansion of ammonia (anhydrous?) and pressure rise that causing explosion.
As per reports in some other news papers, use of steam instead of hot water led pressure rise. Hot water use limits the temperature compared to steam and may be this is one of the reasons for the incident.
Reports indicating fire extinguished rise questions of whether it is ammonia fire or any other fire.
