Equipment  repair  operations  and  the  use  of  POL products  and  55-gallon  fuel  drums  must  be  closely monitored  to  avoid  any  contaminating  spills. Lubricating  oil,  fuel,  hydraulic  fluids,  transmission fluids,  and  antifreeze  contain  hazardous  chemical properties. When these items are mishandled and spilled,  they  can  leak  into  the  groundwater  system  or into   the   human   food   chain. Mishandling   the “hurdy-gurdy” while dispensing fuel in vehicles or in fuel cans can cause excessive fuel spills that can be disastrous  to  the  environment. Fifty-five-gallon   fuel drums and POL products should be stored at least 50 feet away from any structure and located so vehicles and equipment  can  be  easily  topped  off  at  the  end  of  each day. Depending on your mission, the POL products and 55-gallon drums should be in a protected position (away from likely avenues of attack) that provides protection to the fuel storage area as well as to adjacent facilities. Fire extinguishers must be placed for easy accessibility and “No Smoking” signs must be posted in the POL products and fuel storage area. Embarked   with   limited   resources,   the maintenance field crew and field crew truck play a major role throughout the air det mission. The field crew  truck  is  loaded  with  the  necessary  tools  and consumable    supplies. These   tools   and   supplies support the reassembling of CESE, setting up light plants,  setting  up  camp  electrical  supply  (generators), repair of hand tools, and so forth. Additionally, the maintenance  field  crew  is  required  at  the  airfield during aircraft flight unloading operations in case a piece of CESE can not start or breaks down while on board the aircraft. Depending on the mission, the maintenance   field   crew   truck   can   be   used   for delivering fuel by loading and securing a 55-gallon drum of fuel in the back of the truck. This expidites fuel runs for equipment on construction projects or for the   camp   generators. The   requirements   for maintenance field crew support requires a radio for communications  with  the  maintenance  field  crew  and the air det camp. A field crew must be equipped with the  proper  communication  capability  to  respond  to mission  requirements  expeditiously. The  air  det  maintenance  supervisor  should  direct the  operations  of  the  maintenance  field  crew  and  also know the status of all CESE assigned to the air det. The  maintenance  supervisor  has  the  responsibility  to set  up  the  maintenance  shop  and  set  up  a  preventive maintenance   schedule   for   CESE   assigned. All maintenance peerformed that requires repair parts, lube   oils,   or   exceeds   one   man-hour   must   be documented. Depending on the duration of the mission, the air det normally schedules means for logistic support and communications  with  the  main  body.  Equipment repair  parts  not  covered  in  the  mod  96  or  mod  98 normally  can  be  acquired  through  this  logistic support.  The  air  det  maintenance  and  equipment management  program  should  mirror  that  of  the  main body.  The  management  guidelines  are  provided  in Equipment   Management,   COMSECOND/COM- THIRDNCBINST 11200.1 series. The success of the air det mission is primary, but should not be attained at the cost of destroyed CESE. Operator’s maintenance is mandatory and must be strongly  enforced  by  the  entire  air  det  chain  of command. CESE damaged by operator negligence or lack   of   operator   maintenance   is   unacceptable. Equipment failure can seriously jeopardize mission success. PROJECTS The primary purpose of the construction platoon is to perform construction operations for the air det with  the  support  of  the  equipment  and  support platoons. Construction tasking covers a large range of tasks that include disaster recovery operations, war damage  repairs,  rapid  runway  repairs,  humanitarian relief,   and   constructing   advance   base   functional components. The tailoring of ratings assigned to the air det is dependent upon the extent and variety of the assigned  tasking. The amount of time allotted to plan construction projects  depends  on  the  urgency  of  the  air  det  to embark  to  the  mission  site.  Urgent  situations  can cause the air det to embark and manage construction projects   with   just   the   basic   TA41   items.   The equipment  platoon  supervisor  has  to  plan  CESE support for the construction projects, and priorities should be set up as soon as possible due to the limited amount   of   CESE   embarked   with   the   air   det. Remember,   priorities   are   subject   to   change, depending  on  operational  conditions. AIR DET MOUNT-OUT/RETROGRADE At  the  completion  of  the  mission,  the  air  det receives orders from higher command to prepare to mount-out to relocate or to return to the main body site.  The  air  det  will  have  to  mount-out  itself  to include   the   weighing   and   balancing   of   CESE, building   pallets,   developing   load   plans,   and developing  convoy  procedures,  if  required.  The  air 2-16
