Nasty Situation in Vancouver, Canada.  Trichloroisocyanuric acid burning at Port Metro Vancouver.  Only dry power can effectively fight this fire

Fire began at Port Metro Vancouver Wednesday afternoon

The substance burning at Port Metro Vancouver is a highly reactive chemical called trichloroisocyanuric acid, confirmed Vancouver Coastal Health.


It is a white, sand-like powder used to kill bacteria. It's not combustible, but is described as a "dangerous explosion hazard" when it reacts with other substances, or is heated.

The acid "gives off irritating or toxic fumes (or gases) in a fire," including chlorine gas, according to safety information posted by the Centres for Disease Control and Prevention in the U.S.

A material safety datasheet for the acid said it is harmful if inhaled, and could cause damage to the kidneys, liver, respiratory, eyes and skin.

Cover eyes and mouth to reduce exposure

People living in Vancouver east of Main Street and north of East 1st Avenue are told to close their windows and remain inside, said Vancouver police in a statement.

A spokesperson for Vancouver Coastal Health described the acid as a "respiratory irritant," that irritates eyes and lungs, but is only dangerous in large amounts.

"If you need to go outside, cover your eyes and mouth with a wet cloth," said Viola Kaminski of Vancouver Coastal Health.




WHAT IS TRICHLOROISOCYANURIC ACID?

Trichloroisocyanuric acid is a bleaching agent and industrial disinfectant. It is also a possible eye and skin irritant. May intensify fire; oxidizer.  When the substance burns it is going to release a hydrogen chloride gas.
