SEATTLE – A “mist” that overpowered a Waste Management worker and sparked a hazardous materials response near Green Lake has been identified as caustic concrete dust, officials said.
Police and a hazmat team were dispatched to the scene, near Green Lake Way and North 50th Street, at about 9:20 a.m. after receiving a report of a person overcome by an unidentified mist or aerosol from a trash container.
A Waste Management worker was found at the scene who had been overpowered by dust or vapor from a trash bin. The worker was taken to the hospital and is reported to be in stable condition.
Hazmat workers gathered samples of the material and tentatively identified it as concrete dust, said a Seattle Fire Department spokesperson. Concrete dust is mildly caustic, which explains the worker’s reaction to getting it in his eyes, the spokesperson said.
The northbound lanes of Green Lake Way near 50th Street are blocked for the incident. Motorists are advised to avoid the area.
