Incident report: Remsen Hall, June 2013

A researcher was flame-sealing a glass tube using an oxy-gas torch. The tube had been dipped in liquid nitrogen to condense its contents before the sealing operation, so the researcher was using a lab wipe to handle the cold glass. The wipe ignited and fell into the laboratory waste box, which also ignited. The researcher extinguished the resulting fire using a dry-chemical extinguisher mounted in the hallway outside the lab. Neither the fire department nor Security was called, nor was the building fire alarm sounded.
