The Phoenix Fire Department responded to a call about hazardous materials Monday afternoon.
At around 4 p.m. Phoenix fire crews arrived in the area of 7th Street and Interstate 17 where they assisted a chemical cleanup by monitoring the air at a concrete manufacturing company.
According to Phoenix fire, the concrete manufacturers produce large concrete pipes by mixing two chemicals that combine to assist in the curing process. The chemicals were mixed too early in the process and began to give off gas from two 1,500-gallon containers.
The chemical cleanup company determined that the threat was increased levels of carbon dioxide and oxygen. Fire crews reported that unless a person was within a 10-foot radius to the mixture there was no threat to personnel or the environment.
The crew will wear Level B protective clothing while loading the products into totes and disposing of the waste according to regulations.
