Sec.  56.6600  Loading practices.



    If extraneous electricity is suspected in an area where electric 

detonators are used, loading shall be suspended until tests determine 

that stray current does not exceed 0.05 amperes through a 1-ohm resister 

when measured at the location of the electric detonators. If greater 

levels of extraneous electricity are found, the source shall be 

determined and no loading shall take place until the condition is 

corrected.
