WALTHAM, Mass. (WHDH) — The fire suppression system went off at a gas station in Waltham Wednesday, covering the gas station and cars in white powder.
The incident happened at the Gulf station on Trapelo Road. Firefighters said the system went off accidentally and the gas station owner told 7News he believes it may have been a malfunction.
“There was a huge truck there, I thought some concrete powder came off of the truck or something,” said Ema Hernandez, who drove by the gas station on the way to work.
The station is now closed as crews clean everything up and restore the system. Six people were evaluated when they were exposed to the substance but officials said the powder is non-toxic and similar to baking soda.
