Narrative:
While recently deicing at the remote deicing pads in den; we idented a potential pitfall in our new procedures. Specifically; as it relates to the limitation against operating the radar near personnel. On the new deice card under step 2 for remote deicing; we are directed to 'accomplish normal flows and checklists up to and including before taxi checklists.' per the recent fom revision; we are now directed at all airports to turn the transponder on in the after start flow. In the classic aircraft; I am led to believe that the radar is energized any time the transponder is not in 'standby.' the pre-deice checklist does not direct you to turn the transponder to standby. This creates a potential radiation hazard for our employees in the bucket directly in front of the aircraft. In our case; we realized the potential and turned the transponder to standby. It is my opinion that this step should be included in the pre-deice checklist. Then as part of the normal after start procedures; the transponder will again be placed in TA/RA.

Title: REPORTER IS CONCERNED THAT THE LACK OF CHECKLIST DIRECTION TO TURN THE TRANSPONDER TO STANDBY PRIOR TO DEICING SUBJECTS THE DEICING CREWS TO RADIATION HAZARDS.
Narrative: WHILE RECENTLY DEICING AT THE REMOTE DEICING PADS IN DEN; WE IDENTED A POTENTIAL PITFALL IN OUR NEW PROCS. SPECIFICALLY; AS IT RELATES TO THE LIMITATION AGAINST OPERATING THE RADAR NEAR PERSONNEL. ON THE NEW DEICE CARD UNDER STEP 2 FOR REMOTE DEICING; WE ARE DIRECTED TO 'ACCOMPLISH NORMAL FLOWS AND CHKLISTS UP TO AND INCLUDING BEFORE TAXI CHKLISTS.' PER THE RECENT FOM REVISION; WE ARE NOW DIRECTED AT ALL ARPTS TO TURN THE XPONDER ON IN THE AFTER START FLOW. IN THE CLASSIC ACFT; I AM LED TO BELIEVE THAT THE RADAR IS ENERGIZED ANY TIME THE XPONDER IS NOT IN 'STANDBY.' THE PRE-DEICE CHKLIST DOES NOT DIRECT YOU TO TURN THE XPONDER TO STANDBY. THIS CREATES A POTENTIAL RADIATION HAZARD FOR OUR EMPLOYEES IN THE BUCKET DIRECTLY IN FRONT OF THE ACFT. IN OUR CASE; WE REALIZED THE POTENTIAL AND TURNED THE XPONDER TO STANDBY. IT IS MY OPINION THAT THIS STEP SHOULD BE INCLUDED IN THE PRE-DEICE CHKLIST. THEN AS PART OF THE NORMAL AFTER START PROCS; THE XPONDER WILL AGAIN BE PLACED IN TA/RA.
