First, you go to the site's procedures. There should be ones covering both job coverage and RWP writing.
Failing that, you might consider writing such a procedure. Just seems like a good idea to me. It ought to cover at least the obvious situations like:
Potential to release radioactive material from the RCA
Potential to exceed administrative dose guidelines or RWP limits
Potential to expose other workers (those not on the RWP or unmonitored personnel) to dose rates, contamination levels, or airborne concentrations which exceed those specified by their RWP's
Potential to create an unmonitored concentration of airborne activity above the DAC
Potential to cause skin contamination or external exposure to a level which would result in a measurable SDE or CDE
Potential to create radiation, contamination, or airborne levels which exceed the posting levels for the area
Entry into an area with unknown radiation levels
Breach of systems with high or unknown internal radiation or contamination levels
Manipulation or removal of temporary or permanent shielding
Handling irradiated fuel or highly irradiated components in the reactor cavity or spent fuel pool
Removal of equipment from the cavity or SFP
Work involving non-radiological safety and health hazards which may interfere with radiation protection or compound the hazards of radiation exposure
Entry into the Containment Building or Drywell when the reactor is critical
Emergency response operations inside the RCA (firefighting, EMS, response to a plant or system failure, etc.)
Entry into the RCA by workers not qualified as Radiation Workers
Removal of material or equipment from a RCA
Transfer of radioactive material from one RCA to another
Gee, it's funny what a guy can remember after eight years of not swinging a meter
If you do write that procedure, I wouldn't refuse a consultation fee should you wish to offer one.
