Final narrative
An employee was working in a research lab with a waste bottle containing 5% thiosulfate and trace amounts of other chemicals including silver nitrate, ammonium nitrate, and residual chemicals from earlier protocol steps. The bottle burst open from the bottom and its contents spilled out through the fume hood and via the partially open stash into the lab. The employee was standing right in front of the fume hood when this occurred, exposing her face, eyes, and neck to the spill. The employee was hospitalized due to chemical burns to her eyes, lips and tongue and to monitor her airway.
Hospitalized Other multiple ear(s), facial locations Multiple chemicals and hazardous materials
An employee was removing a hose from a chemical tank after filling the tank with hexamethylenediamine (HMD). He checked the line to ensure that the hose was clear, then disconnected the hose at the connection. Residual chemical sprayed onto his face, causing a second-degree burn. He was hospitalized.
A shipping/receiving operator was working on a loading rack, loading a railcar. A 2-inch discharge cap failed and released pressure along with sulfuric acid from the railcar. The acid sprayed onto the employee, who suffered burns to the chest and the lower facial area. The employee was hospitalized.
An employee was pressure washing truck scales when they were splashed with water and an unknown chemical on their leg and immediately experienced a burning sensation. The employee was hospitalized with a chemical burn and required surgery.
An employee was on a ladder disconnecting a 1-inch hose, known to have last carried acrylic acid that had been drained. When the hose was disconnected, residual acid dripped onto the employee's shoulder/arm area, causing a second-degree chemical burn.
Employees were removing scaffolding that was used to repair an ion exchange tank. The line was undergoing the regen process when a piece of scaffold struck a PVC pipe that transported hydrochloric acid (HCl). The injured employee was placing material inside a scaffold rack when he was sprayed in the face with HCl and sustained chemical burns to his eyes, face, chest, right arm, and left leg.
