A chemical cloud rose from the truck because someone disposed of a can of muriadic acid. “The can leaked and formed a little cloud,” EMS Supervisor Craig O’Malley said.
Muriadic acid is used to clean concrete and stone, he said.
The truck was near the Woods Hole Fire Station on Woods Hole Road when the cloud formed and fire officials pulled the truck over to the station. A tier one haz mat team responded, which is the investigatory level of haz mat response.
The hazmat team worked with fire officials to remove the chemical.
The acid is, O’Malley said, “a very weak acid.” Once the cloud dissipated there were no other issues and there was no danger to the public, he said.
