Mysterious white powder found at Post Office



A mysterious white powder, which was later identified to be Sodium Bicarbonate, or Baking Soda, temporarily closed the Barrigada Post Office

Around 11 am, Guam Fire Department units were dispatched to the Barrigada Post Office after employees reported a white powdery substance on the floor.

The building was then evacuated and GFD’s Hazardous Materials Team and CST were dispatched to assist.

GFD says that testing was conducted on-site to identify the substance.

Local and military agencies were able to identify the substance, which was sodium bicarbonate or baking soda.

An All-clear sign was given at 1:45.

The Guam Fire Department would like to remind the community to always notify the proper authorities when encountering a suspicious substance that may be dangerous or harmful.
