Nine Mile also uses booties and gloves for inspections and observations under the following conditions: 400-25,000 dpm/100cm2, dry work only, and no climbing, kneeling, or sitting. For the most part this dressout is used for supervisor walkdowns or to check on crews, RP surveys, OPS walkdowns or to hang clearances or security walk throughs. Usually if the activity involves "work" then it goes to a single set.
