TUCSON - Reports of "blue powder," later determined to be an ammonia-based fertilizer, closed the Avra Valley Road on-ramp at Interstate 10 for about two hours this morning as hazmat teams stabilized the chemical and cleared the roadway.
At about 9 a.m. this morning, crews from the Northwest Fire District's Hazmat team were called to the I-10 on-ramp at Avra Valley Road after there was a report of "blue powder" falling on the roadway from a truck, according to a NWFD news release.
Crews responded and as they were cleaning the scene, two members felt burning in their throats. A Hazmat team arrived and tested the chemical to determine that it was an ammonia-based fertilizer. The Hazmat team, in protective gear, stabilized the chemical and reopened the roadway within two hours of the call.
The ADOT members were assessed and released at the scene.
