away from your body and take care that you do not  injure  others  with  it. When working near other people, carry your range poles or level rods vertically against your body  so  that  another  person’s  head  or  eyes  will not be injured if you turn suddenly. Do not hold a stake or bull-point with your hand around the shank while another person is driving it with a sledgehammer.  Do  not  let  a  tape  or  plumb  bob cord  slide  fast  through  your  hands. Always  use  tools  correctly  and  for  the  purpose for which they are intended. For example, when cutting  brush  near  the  ground  with  a  machete, swing it away from your legs and feet. Never cut at short range from your body. Be sure that the radius of your swing is clear of obstructions, such as vines or twigs, that might deflect the intended direction of the swing. Use your full arm’s length to get a safe-swing radius. Always work at least 10  ft  away  from  the  nearest  person.  If  it  is necessary to use an ax to clear an area, you can prevent painful blisters by wearing a pair of thin gloves. Above all, use common sense and consider the  possible  results  of  your  actions. To  climb  poles  and  trees  safely,  it  is  best  to use authorized climbing equipment. A lineman’s pole climbers are made of steel and have a strap loop  and  short  spur.  Tree  climbers  have  straps, pads for protection against friction, and a longer spur  for  penetrating  bark.  To  avoid  falling,  use both  belt  and  straps.  Except  in  an  emergency, never  work  in  or  on  trees  during  a  high  wind. Watch out for power lines that may be in contact with  the  tree  you  are  climbing. Burning  operations  should  always  be  con- ducted in the clear, where the fire will not ignite tree leaves or limbs, dry wooded areas, or nearby buildings.  Remember  that  it  is  imperative  that  all burning  or  smoldering  material  be  completely extinguished  before  it  is  left  unattended. When   practicable,   use   only   nonflammable solvents  for  cleaning  instruments.  Do  not  leave the  caps  off  or  the  stoppers  out  of  flammable liquid  containers.  Use  solvents  only  in  a  well- ventilated  location. All of the above could be boiled down to this: ALWAYS   USE   GOOD   JUDGMENT   AND COMMON  SENSE. FOLLOWING  SAFETY  PROCEDURES IN TRAFFIC A party working on a highway where vehicular traffic  is  proceeding  is  in  great  danger  of  being struck. Every motion made by a member of such a  party  must  be  made  with  a  continuing,  full awareness  that  vehicular  traffic  is,  in  fact, proceeding as usual. The dangers of the situation should be minimized as much as possible by the following  measures  as  well  as  by  others  that  some situations may require. Work  should  be  scheduled  as  much  as  possible to  take  place  during  those  hours  when  traffic is   slack.   Work   during   “rush   hour”   on   a metropolitan  highway,  for  instance,  could  be  so dangerous  as  not  to  be  a  practical  endeavor. Adequate   traffic   warning   signs,   such   as “Men   Working,”   “Drive   Slowly,”   “Single   Lane Ahead,”  and  the  like,  should  be  placed  where  they will be most effective in warning drivers and, if possible, in detouring traffic away from the field party. If detouring requires two-way traffic on a single  lane,  a  flagman  has  to  be  posted  at  each end  of  the  lane. Signs,  barriers,  and  equipment  in  use,  such  as instruments, targets, and the like, should be made as conspicuous as possible by the attachment of bright-colored   bunting.   Personnel   should   also make  themselves  as  conspicuous  as  possible  by wearing  orange-colored  shirts,  vests,  or  jackets. One last word of advice may seem inconsistent with  your  standards  about  what  constitutes proper  performance  of  duty.  Suppose  you  are functioning as an instrumentman with a party on a highway, and you suddenly observe that a car out of control is bearing down on the instrument at high speed. You will have a strong impulse to attempt  to  rescue  the  instrument.  Do  NOT  do  this if  it  could  result  in  death  or  injury  to  yourself. ADDITIONAL  DUTIES  OF A  SURVEY  CREW Other  tasks  that  you  might  perform  as  a survey crew member include the maintenance of various   surveying   equipment   and   accessories, preparation  of  the  field  party’s  essential  needs, field  sanitation,  and  the  conducting  of  prestart checks  and  operator’s  maintenance  of  government survey vehicles. MAINTAINING   SURVEYING EQUIPMENT Generally,  the  maintenance  of  surveying equipment and accessories involves proper clean- ing and stowage. For example, steel tapes, brush hooks,  axes,  chain  saws,  and  so  forth,  must  be cleaned and dried and, if necessary, a thin coat 12-31
