Risks associated with the workplace
Slips, trips and falls are the main causes of injuries. Beware of slippery surfaces, caused by the use of tools, and threats of trip-
ping caused by the pneumatic system. Proceed with caution in an unknown environment. There may be hidden threats, such as
electricity or other utility lines. Pneumatic tool is not intended for use in potentially explosive atmospheres and is not isolated from
contact with electricity. Make sure, that there are no electric wires, gas pipes, etc., that can cause a threat in the event of their
damage by using the tool.
Hazards arising from vapors and dust
Dust and fumes caused by using a pneumatic tool can cause bad health condition (such as cancer, birth defects, asthma and/or
inflammation of the skin). There are necessary: a risk assessment and implementation of appropriate control measures in relation
to those risks. The risk assessment should include the effect of dust created by using tools and the possibility of excitation of the
existing dust. Operation and maintenance of the pneumatic tools should be carried out according to the recommendations of the
manual, This will minimize the emission of fumes and dust. The air outlet must be aimed to minimise generating dust in a dusty
environment. Where dust or fumes are created, priority should be to control them at the source of their emission. All integrated
functions and equipment for collection, extraction or reduction of dust or fume should be properly operated and maintained in
accordance with manufacturer's recommendations. You should select, maintain and exchange inserted tools according to the
manual, to prevent increase of and dust. Wear suitable respiratory protective equipment, in accordance with the instructions of an
employer and in accordance with the requirements of hygiene and safety. Working with certain materials causes emission of dust
and vapors, resulting in the formation of a potentially explosive atmosphere.
Noise hazard
Exposure, without any protection, for high noise levels can cause permanent and irreversible hearing loss and other problems,
such as tinnitus (ringing, buzz, whistling or humming in the ears). It is necessary to perform the risk assessment and implement
appropriate control measures in relation to those risks. The appropriate checks, performed in order to reduce the risk, may include
activities such as: application of insulation materials to prevent the "ringing" of the workpiece. Use hearing protection in accord-
ance with the instructions of employer and in accordance with the requirements of hygiene and safety. Service and maintenance
of the pneumatic tool should be carried out according to the recommendations of the manual, to avoid the unnecessary increase
of noise level. If the pneumatic tool has a muffler, you should always make sure that it is correctly mounted when you use the
tool. Select, maintain and replace worn inserted tools according to the recommendations of the manual. This will allow to avoid
the unnecessary increase in noise.
Risks of vibrations
Exposure to vibration may cause permanent damage to the nerves and blood supply to the hands and arms. You should wear
warm clothing when working at low temperatures and you should keep your hands warm and dry. If you experience numbness,
tingling, pain or skin whitening in the fingers and hands, you should discontinue the use of pneumatic tool, and then inform your
employer and seek medical advice. Operation and maintenance pneumatic tool according to the recommendations of the manual,
will allow to avoid the unnecessary increase of vibration. Do not allow the inserted tool to vibrate on the workpiece, as this may
cause a vibration build-up. You should select, maintain and exchange inserted tools in accordance with the recommendations
in the instruction manual, to prevent unnecessary increase in vibration. Support the weight of pneumatic tool by using bases,
tensioners or stabilizers if it is possible. Hold the tool, with light but a firm grip, taking into account the required reaction forces,
because the risk from vibration is ususally much larger, when the grip force is higher. Use paper dividers, if they have been pro-
vided with the welded abrasive tool.
Additional safety instructions for pneumatic tools
Air under pressure can cause serious injury:
- always shut off the air supply, drain hose of air pressure and detach tool from air supply, when it is not in use, before changing
accessories or performing repairs;
- never direct the air stream at yourself or anyone else.
Hose hitting can cause serious injury. You should always check for damaged or loose hoses and fittings. Every time when there
are used universal screwed connection (claw couplings), you should apply the protecting pins and connectors against the possibil-
ity of damage to the connections between the hoses and between the hose and tool. Do not exceed the maximum air pressure
specified for the tool. Never carry the tool, by holding it by the hose.
Warnings related to rebounding of the tool towards the operator
Rebound of the tool toward the operator is a sudden reaction to a blocked or clenched grinding wheel or other accessory. Block-
ing or clamping causes sudden stopping of the rotating accessory, which results in rotation of the tool in opposite direction to the
rotation of accessory. For example, if the grinding wheel is locked or clamped by a workpiece, grinding wheel edge, that enters
the clamping point, can dig into the surface of the material causing that the grinding wheel will get out or will be thrown out. The
grinding wheel may also get out towards or away from the operator, depending on the direction of movement of the grinding wheel
in the place of clamping. Grinding wheels may also break under these conditions. Rebound in the direction of operator is the
result of misuse and / or failure to follow instructions of this manual. This situation can be avoided by compliance to the following
