Instrument, Electrical & Analytical Work meeting all the following criteria:
Red tags are not required (Energy Control Measures Not Required)
Work is not potentially spark producing in an electrically classified area
Equipment is not contaminated with process chemicals
Work that does not require process line and/or equipment opening
No work on bare conductors greater than 50 volts
No possibility of changing operating process control parameters
Activities in a non-process area:
* Tasks as a minimum require signing the Visitor Log
