Chemical  Exposure  Mechanisms  •  Inhala:on            •  Absorp:on  (dermal)  •  Inges:on  •  Injec:on  

•  Inhala:on          Use  a  fume  hood      •  Absorp:on  (dermal)    Wear  gloves  and  a  lab  coat  •  Inges:on            Don’t  lick  the  lab  bench  •  Injec:on            Proper  needle  e:que=e  

Many  of  these  exposure  mechanisms  can  be  mi:gated  by  proper  use  of:    •  engineering  controls    •  Personal  protec:ve  equipment  (PPE)  

Things  not  to  touch  wearing  gloves  Things  you  will  touch  later  without  gloves    face  or  skin,  computers,  door  handles,  etc  

No  door  handles!!!!

Hazard  classes  •  Health  hazards  (acute  and  chronic)  •  Contact  hazards  (corrosives)  •  Flammable  and  Explosive  hazards  •  Reac:ve  hazards    

 (explosives,  oxidizers,  water  and  air  reac:ves)  

The  hazard  classifica:on  of  a  chemical  must  be  taken  into  account  when  using,  transpor:ng,  was:ng,  and  storing  chemicals.
