III.  Safety Notice

Proper installation and start-up is essential to the safe and reliable operation of all valve 
products.  The  relevant  procedures  recommended  by  BHGE,  and  described  in  these 
instructions, are effective methods of performing the required tasks.

It  is  important  to  note  that  these  instructions  contain  various  “safety  messages” 
which should be carefully read in order to minimize the risk of personal injury, or the 
possibility that improper procedures will be followed which may damage the involved 
BHGE product, or render it unsafe. It is also important to understand that these “safety 
messages” are not exhaustive. BHGE can not possibly know, evaluate, and advise any 
customer of all of the conceivable ways in which tasks might be performed, or of the 
possible hazardous consequences of each way. Consequently, BHGE has not undertaken 
any such broad evaluation and, thus, anyone who uses a procedure and/or tool, which 
is  not  recommended  by  BHGE,  or  deviates  from  BHGE  recommendations,  must  be 
thoroughly satisfied that neither personal safety, nor valve safety, will be jeopardized by 
the method and/or tools selected. Contact your local Green Tag Center if there are any 
questions relative to tools/methods.

The installation and start-up of valves and/or valve products may involve proximity to 
fluids at extremely high pressure and/or temperature. Consequently, every precaution 
should be taken to prevent injury to personnel during the performance of any procedure. 
These precautions should consist of, but are not limited to, ear drum protection, eye 
protection,  and  the  use  of  protective  clothing,  (i.e.,  gloves,  etc.)  when  personnel  are 
in,  or  around,  a  valve  work  area.  Due  to  the  various  circumstances  and  conditions 
in  which  these  operations  may  be  performed  on  BHGE  products,  and  the  possible 
hazardous consequences of each way, BHGE can not possibly evaluate all conditions 
that might injure personnel or equipment. Nevertheless, BHGE does offer certain Safety 
Precautions, listed in Section II, for customer information only.

It is the responsibility of the purchaser or user of BHGE valves/equipment to adequately 
train all personnel who will be working with the involved valves/equipment. For more 
information on training schedules, please contact your local Green Tag Center. Further, 
prior to working with the involved valves/equipment, personnel who are to perform such 
work should become thoroughly familiar with the contents of these instructions.
