TM 9-243 Section II.  SAFETY RULES (POWER TOOLS) Safety is a very important factor in the use of power tools and   cannot   be   overemphasized.      By   observing   the following   safety   guidelines,   you   can   assure   maximum benefits from the tools you use and minimize chances of serious injury. 1. Never   operate   power   equipment   unless   you   are completely familiar with its controls and features. 2. Inspect  all  portable  power  tools  before  using  them. See that they are clean and in good condition. 3. Make  sure  the  work  area  has  plenty  of  light.    Never work   with   power   tools   in   dark   areas   where   you cannot see clearly. 4. Be   sure   the   tool   switch   is   in   the   "OFF"   position before connecting a power tool to a power source. 5. When operating a power tool, give it your FULL and UNDIVIDED ATTENTION. 6. DO  NOT  DISTRACT  OR  IN  ANY  WAY  DISTURB another   person   while   they   are   operating   a   power tool. 7. Never  try  to  clear  a  jammed  power  tool  until  it  is disconnected from the power source. 8. After    using    a    power    tool,    turn    off    the    power, disconnect  the  power  source,  wait  for  all  movement of  the  tool  to  stop,  and  then  remove  all  waste  and scraps   from   the   work   area.      Store   the   tool   in   its proper place. 9. Never plug the power cord of a portable electric tool into   a   power   source   before   making   sure   that   the source  has  the  correct  voltage  and  type  of  current called for on the nameplate of the tool. 10.   Do   not   allow   power   cords   to   kink   or   to   come   in contact with sharp objects, oil, grease, hot surfaces, or chemicals. 11.   Never use a damaged cord.  Replace it immediately. 12.   Check   electrical   cables   and   cords   frequently   for overheating.      If   extension   cords   are   needed,   use only approved cords. 13.   See    that    all    cables    and    cords    are    positioned carefully    so    that    they    do    not    become    tripping hazards. 14.   Treat  electricity  with  respect.    If  water  is  present  in the   area   of   electrical   tool   operation,   be   extremely cautious and disconnect the power tool if necessary. 15.   Wear  safety  glasses  when  soldering  or  using  power tools. Section III.  SAFETY EQUIPMENT Safety  equipment  is  for  you.    it  will  protect  you  from injury   and   could   save   your   life.      Some   of   the   more common  types  of  safety  equipment  are  illustrated  and described in this section. Safety  shoes  protect  and  prevent  injury  of  loss  of toes.    Some  safety  shoes  are  designed  to  limit  damage to your toes from falling objects. A steel plate is placed in the toe area of such shoes so  that  your  toes  are  not  crushed  if  an  object  falls  on them.    Other  safety  shoes  are  designed  for  use  where danger  from  sparking  could  cause  an  explosion.    Such danger  is  minimized  by  elimination  of  all  metallic  nails and eyelets and the use of soles that do not cause static electricity. Proper  eye  protection  is  of  the  highest  importance  for everyone.  It is necessary because of hazards caused by infrared   and   ultraviolet   radiation,   or   by   flying   objects such  as  sparks,  globules  of  molten  metal,  or  chipped concrete   and   wood,   etc.      These   hazards   are   always present during welding, cutting, Change 3  2-3
