What happened: Student got MnO2, carbon black and isopropyl alcohol in their eye. Went to washroom to wash it out, lab manager got them to eyewash and got me, I called security and then while waiting outside to escort them to the lab, called the department safety guy, who called the university safety people (or security did?)
Then I printed it the MnO2 and carbon black SDS as they were having trouble finding them and made sure they would go along with him wherever he wound up.
