Accident in Taiwan: a driver dies after colliding with an ammonia container - 19/11/2021

Fatal Road Accident but No Leak from the Liquid Ammonia Container

A Dramatic Driving Error Leads to a Collision with an Ammonia Container

The driver of the liquid ammonia container slowed down to stop at a red light. A gravel truck driver coming from behind did not brake and crashed into the container.

Due to the impact, the container tipped over. The gravel truck driver, aged 72, was trapped in the cabin, which immediately caught fire.

10 vehicles and 35 firefighters responded to the accident.

Despite the damage to the container, there was no leak or environmental pollution.

Liquid Ammonia Transportation

There are 4 UN codes for ammonia transport:

- Anhydrous ammonia: UN 1005: Toxic and corrosive gas.

- Aqueous ammonia solution, with a density < 0.88 and containing more than 50% ammonia: UN3318 - Non-toxic, corrosive gas (with potentially a flammability hazard in a confined space).

- Aqueous ammonia solution of density < 0.88 and containing between 35% and 50% ammonia: UN2073, non-flammable and non-toxic gas.

- Aqueous ammonia solution, with a density between 0.957 and .88, and containing between 10 and 50% ammonia: UN 2672, corrosive liquid.

Solutions containing no more than 10% ammonia are not subject to ADR regulation.

Based on the images, it is presumed to be UN2672.
