UCLA Lab Fire: December 29, 2008
Sheri Sangji （ using plastic syringe to
transfer tert‐butyllithium）
The latex gloves she was wearing
were not resistant to methyl
mercury – it passed through the
glove, through her skin, entered
her blood system and resulted in
her
death
weeks
after
the
exposure.
She was wearing nitrile gloves but no
lab coat.
The students assisting her did not
remember to put her under the safety
shower.
Sheri died January 16, 2009 of severe
burns

Know the risks.
Wear gloves and lab coat.
Remember where safety shower and other emergency
equipment is – you may need to be the one who needs to be
ready to act when your lab mate is unable to help
himself/herself.
