Lithium Battery Incident

Updated June 09, 2016

Incident or near miss – On 4/19/16 at ~6 pm, an undergraduate (hereafter referred to as “student”) and his girlfriend (not an MIT student) were in a professor’s office working on student’s UROP project, a robotic exoskeleton designed to increase vertical leap distance for the user.  The student had been told that he was only to test the project with the assistance of a graduate student or postdoctoral researcher, but no one from the lab group was available that day.  The thesis project was due very soon and the student needed data, so his girlfriend

Animal/Mouse Bite

Updated July 15, 2015

Incident or near miss –

On May 21, 2015 a research assistant was restraining a mouse for the purpose of subcutaneously injecting a medication. They were wearing appropriate personal protective equipment (PPE), including gloves on both hands. However, one particular mouse turned its head during the restraint and bit the middle finger of his left hand.

Incident or near miss – Brief description

Researcher passing through a campus building hallway on a Saturday afternoon smelled a burning odor coming from a lab.  After knocking on the door and getting no answer, he proceeded to leave building, activating fire alarm.  When the fire department arrived, they found a hot plate/stirrer with a scorched beaker on top out on an open lab bench.  They turned off the hot plate and allowed people back into the building, but not into the lab until EHS verified it was safe.
