 HAZARD  AND  RISK  ASSESSMENT  FORM  –  C1  

NAME:                 DATE:  5  May  2015  

WORKBOOK  AND  PAGE  REFERENCE:  10  

NOTES      1)  Assess  Risk  Class  for  each  reagent,  process  and  product  as  per  sections  4.3  &  4.4  of  the  Safety  Handbook.  Use  numbers  1-­‐4.    2)  Assess  Risk  rating:  how  likely  is  the  hazard  to  hurt  or  injure  someone  and  how  severely?  Use  one  abbreviation  from  each  group:                HL  =  Highly  Likely;  L  =  Likely;  U  =  Unlikely;  HU  =  Highly  Unlikely  AND  XS  =  Extremely  Severe;  S  =  Severe;  M  =  Moderate;  Sl  =  Slight.    3)   In  exceptional   circumstances   a  Modified   Risk   Class  may   be   provided.   A   reason  must   be   specified   and   explicitly   approved   by   your  supervisor.    4)  Procedure  Class  is  then  the  highest  risk  class/modified  risk  class  attributed  to  any  individual  reagent,  process  or  product.    5)  An  appropriate  Reaction  Label(s)  must  be  generated  for  and  physically  accompany  each  process  (except  class  0).    6)  If  a  Scheduled  Carcinogen  is  being  used,  the  University  Risk  Assessment  for  handling  such  chemicals  must  also  be  completed.

 HAZARD  CONTROL  AND  SPECIAL  STORAGE/WASTE  DISPOSAL  MEASURES:    Lab,  coat,  loves,  safety  classes  should  be  worn;  gloves  should  be  changed  to  reduce  chance  of  penetration  of  substances.    Waste  should  be  disposed  of  in  organic  halogenated  waste  container.    USER  DECLARATION:  I  understand  all  hazardous  aspects  of  this  process.  I  am  appropriately  trained  in  the  use  and  handling  of  all  reagents   and   equipment   identified   and   understand   necessary   precautions   to   take   in   the   event   of   an   adverse   incident.   I  acknowledge  that  I  am/am  not  handling  chemicals  belonging  to  a  Schedule  for  Restricted  or  Prohibited  Carcinogens;  if  I  am  using  such  a  chemical,  I  have  completed  an  additional  more  detailed  University  Risk  Assessment  for  handling  a  scheduled  carcinogen.  Name:_____________________________   Signature:  ___________________________________              Date:  _______________
