Failure To Segregate Waste Streams Mixes Nitric Acid And Organic Solvent, Causes Waste Bottle To Explode From Pressure Buildup; Written Procedures Did Not Reflect Current Procedures - February 2015
What happened?
On February 2, 2015 in a chemistry teaching lab three undergraduate students and a graduate teaching assistant (TA) were injured and required medical attention when a glass waste bottle exploded. The bottle exploded while a student tried opening the container to add waste during the course of the planned experiment. The lab was evacuated and the Texas Tech Police Department and the Lubbock Fire Department responded to secure the lab and transport the injured to the hospital.
All students and personnel were wearing appropriate personal protective equipment including lab coats, safety goggles and gloves.
