1.  General Safety Precautions 
 
 
  Do not attempt to use this product unless you have received training in the handling and 
use of oilfield explosive products. 
 
  Refer  to  and  apply  the  procedures  listed  in  the  Recommended  Practices  for  Oilfield 
Explosives Safety; API Recommended Practice 67 (RP67) before assembling or using 
this product. 
 
  Failure to follow the assembly instructions can result in extensive bodily injury and death. 
 
  Do not throw, slide, or roughly handle boxes of explosives. 
  The assembly and arming of the cutters should only take place at the job site where they 
are to be used and immediately prior to running the cutter into the pipe. If there is any 
delay the device should be disarmed and safely stored. 
 
  Load only in designated areas. Floors are to be covered with rubber mats. 
 
  No open flames, welding, or sparking devices are to be used in the loading area while 
handling explosives. 
 
  No smoking in the loading area while handling explosives. 
 
  No RF-transmitting devices such as cellular telephones, two-way pagers, or hand held 
radios are to be in the loading area. 
 
  Never strike, drop, force, heat, grind, drill, or hammer on any explosive item or explosive 
assembly. 
 
  Use only the tools designed to be used with or for explosive loading. 
 
  Do  not  attempt  to  alter  or  modify  any  part  of  the  assembly.  Use  only  manufacturer 
approved parts. 
 
  Use only the proper razor blades and cutting blocks to cut detonating cord. Never use 
side cutters, pocketknives, scissors, or a cap-crimpier to cut detonating cord. Aluminum 
covered detonating cord is cut using a small pipe cutter. 
 
  Always use approved methods and carriers for the transportation of explosives to the job 
site. 
  Do  not  handle  explosives  when  electric  storms  (thunder  and/or  lightening)  are  in  the 
immediate area. Do not handle explosives in a sandstorm or similar situation that can 
result in the build-up of static electric charges.
