The 0031h flag is NOT the "customer service"-only flag (referred to as the "radioactive" tag in the official EQ customer service handbook). A few of the non-gm/guide items have that flag, yet summoning them will cause no problems for non-gm's, and at the same time, many radioactive items (i.e. verdant plate) lack the 0031h flag, and yet WILL strike a player dead real fast
.
As to the TRUE location of that flag, I personally have no idea, and am not really interested enough at this point to go find out
