Work related hazards

Tool  operation  may  be  hazardous  to  operator's  hands,  e.g.  by
pinching, hitting, cutting, abrasion or burns. Wear appropriate gloves
for hand protection. Operator and maintenance personnel must be
physically fit to handle the weight and power of the tool. Hold the tool
correctly. Be prepared to counter-act against normal or unexpected
movements and always have both hands ready. It is recommended
to  use  support  arm  wherever  possible  in  all  cases,  when  reaction
torque  absorbing  measures  are  required.  However,  if  that  is  not
possible, use of side handles for straight tools and gun holder tools
is  recommended.  Reaction  rods  for  angle  screwdrivers  are
recommended. In all cases it is recommended to use measures to
absorb reaction torque above: 4 Nm for straight tools, 10 Nm for gun
handle tools, 60 Nm for angle screwdrivers. Release the pressure
on start/stop element in case of power outage. Use only lubricating
media recommended by the manufacturer. Fingers may get pinched
in screwdrivers with open grippers. Do not use the tools in restricted
areas  and  avoid  hand  pinching  between  the  tool  and  processed
piece, especially when undoing a thread.

Hazards related to repetitive movements

When using a pneumatic tool for operation that involves repetitive
moves,  the  operator  is  exposed  for  discomfort  of  hands,  arms,
shoulders, neck and other body parts. When using a pneumatic tool,
keep comfortable body posture that ensures the right feet position
and avoid uneasy or unbalanced body postures. Change your body
posture  when  working  for  a  long  time,  it  helps  to  avoid  discomfort
and  fatigue.  When  experiencing  constant  or  recurring  discomfort,
pain,  pulsating  pain,  tingling,  numbness,  burning  sensation  or
stiffness,  do  not  ignore  the  symptoms,  inform  your  employer  and
consult a doctor.

Accessory related hazards

Disconnect the tool from power supply before changing the working
tool or an accessory. Do not touch sockets and accessories when
operating  the  tool,  there  is  a  higher  risk  of  cuts,  burns  or  injuries
caused  by  vibrations.  Use  accessories  and  consumables  only  in
sizes  and  types  recommended  by  the  manufacturer.  Use  only
impact  sockets  in  good  technical  condition.  Bad  condition  or  non-
impact sockets used with impact tools may fall apart and turn into
projectile.

Workplace related hazards

Slipping, tripping and falling are the main reasons of injuries. Avoid
slippery surfaces when using the tool and tripping hazards caused
by  compressed  air  system.  Be  careful  in  unknown  environment.
There  may  be  hidden  dangers,  such  as  electricity  or  other  utility
systems.  The  pneumatic  tool  is  not  designed  for  use  in  explosion
hazardous areas and has no electric insulation. Make sure there are
no  electric  wires,  gas  pipes  etc.  that  may  be  dangerous  when
damaged with the tool.

Dusts and fumes related hazards

Dusts and fumes produced with the pneumatic tool may cause bad
health  condition  (e.g.  cancer,  congenital  defects,  asthma  and/or
dermatitis),  so  the  risk  assessment  is  necessary,  and
implementation  of  appropriate  control  measures  for  the  hazards.
The  risk  assessment  should  include  impact of  dust  produced  with
the  tool  and  possibility  to  stir  up  and  lift  existing  dust.  Air  outlet
should  be  directed  in  a  way  to  minimise  stirring  up  dust  in  dusty
environment. Wherever dust and fumes are produced, it is a priority
to  control  the  emission  at  the  source.  All  integrated  functions  and
equipment  used  for  collection,  extraction  and  reduction  of  dust  or
smoke should be used appropriately and maintained in accordance
with the manufacturer's guidelines. Use respiratory tract protection
in  accordance  with  the  employer  instructions,  as  well  as
occupational health and safety rules.

Noise hazards

Exposure to high noise without any protection may cause permanent
and  irreversible  hearing  loss and  other  problems,  such  as  tinnitus
(sensation of ringing, buzzing, whistling or humming in ears). Risk
assessment is necessary, and implementation of appropriate control
measures  related  to  the  hazards.  Appropriate  control  aiming  to
reduce  risks  can  include  measures  such  as  silencing  materials  to

prevent “ringing” of processed piece. Use hearing protection in

accordance with the employer instructions, as well as occupational
health and safety rules. Operate and maintain the pneumatic tool in
accordance with the instruction manual, which allows to prevent

unnecessary  increase  of  noise.  When  the  pneumatic  tool  is
equipped  with  a  muffler,  always  make  sure  it  is  installed  properly
when operating the tool. Select, maintain and replace worn out items
in  accordance  with  the  instruction  manual.  It  will  prevent
unnecessary increase of noise.

Vibration hazards

Exposition  to  vibrations  may  cause  permanent  injuries  of  nervous
and vascular systems in hands and arms. Keep hands away from
screwdriver  sockets.  Wear  warm  clothes  when  working  in  low
temperatures  and  keep  your  hands  warm  and  dry.  In  case  of
numbness, tingling, pain or whiteness of skin on fingers or hands,
stop using the pneumatic tool, inform your employer and consult a
doctor.  Operation  and  maintenance  of  the  pneumatic  tool  in
accordance  with  instruction  manual  allows  to  avoid  unnecessary
increase of vibrations. Do not use worn out or unfit sockets, because
they may cause significant increase of vibrations. Select, maintain
and  replace  worn  out  items  in  accordance  with  the  instruction
manual. It will prevent unnecessary increase of vibration level. Use
protective  installations  wherever  possible.  If  possible,  support  the
tool  weight  in  a  stand,  tensioner  or  with  a  balancer.  Vibration
hazards are usually  higher  with  stronger  hand  grip,  therefore  hold
the tool with light but firm grip, while considering reaction forces that
may appear.

Additional safety instructions regarding pneumatic tools

Pressurised air may cause serious injuries:
- Always cut off air supply, release air pressure from the hose and
disconnect the tool from air supply at all times, when the tool is not
in use, before changing accessories or before repairs;
- Never direct air stream at yourself or another person.
Hitting with a hose may cause serious injuries. Always inspect the
equipment for damaged or loose hose and connectors. Make sure
to direct cold air away from hands. Do not use quick coupler on inlet
of  an  impact  tool  or  pneumatic  and  hydraulic  tool.  Use  threaded
couplings made of hardened steel (or material of similar strength).
Each time when universal rotation joints are used (claw couplings),
use securing pins and securing fasteners that protect from damages
between  hoses  and  between  a  hose  and  the  tool.  Do  not  exceed
maximum air pressure specified for the tool. Air pressure is critical
for  safety  and  affects  efficiency  in  systems  with  adjustable  torque
and in continuously rotating tools. In this case observe requirements
for hose length and diameter. Never carry the tool when holding by
its hose.
