(12)  Wash  hands  thoroughly  after  handling  filter  paper. 
2-5.  Operation  Under  EAtreme  Conditions: 
a.  If  dust  storms  or  heavy  burning  occur  in  the  area  of  the  GFU,  papers  may  be  changed  at 
12  or  24  hour  intervals  (as  required)  to  prevent  contaminant  buildup  on  the  papers. 
b.  The  GFU  should  be  turned  off  during  severe  local  storms  if,  in  the  opinion  of  local 
personnel,  the  filter  paper  might  become  clogged,  the  vacuum  relief  valve  might  open  in  less 
than  6  hours  of  operation,  or  the  unit  might  sustain  damage.  After  the  storm  subsides,  the 
blower  will  be  restarted  and  the  paper  changed  according  to  the  following  rules: 
(1)  If  the  original  paper  had  a  run  time  of  at  least  24  hours,  change  the  paper  and 
adjust  the  date  for  the  next  paper  change  so  it  has  a  run  time  of  at  least  24  hours  but  not 
more  than  48  hours. 
(2)  If  the  original  paper  had  a  run  time  of  less  than  24  hours,  restart  with  the  same 
paper  and  make  the  next  paper  change  at  the  normal  scheduled  time. 
(3)  If  the  vacuum  relief  valve  opens,  change  the  paper  and  schedule  the  following 
paper  change  to  give  an  exposure  of  between  24  and  48  hours. 
c.  These  procedures  are  to  be  used  only  during  extreme  conditions  and  will  be  fully 
explained  on  the  inner  envelope.  Special  permission  is  not  required.
