Safety in Operation
The safety procedures for operating air tools are everyone's responsibility. The following lists several
aspects of air tool safety that should be considered during operation. Please be aware of the these
aspects and report any unsafe practice you see to a supervisor or safety officer immediately.
1) The inserted tool on heavy types of percussive, non-rotary power tools is exposed to heavy strains
and can, after long period of use, break due to fatigue.
2) Unexpected tool movement or breakage of inserted tool may cause injuries to the lower limbs, in
particular the feet.
3) Unsuitable postures may not allow counteracting of normal or unexpected movement of the power
tool. (A working position shall be adopted which remains stable in the event of a break up of the
inserted tool.)
4) Support the work piece properly.
5) Holding the inserted tool by the free hand can be a source of vibration damage.
6) If the tool jams, shut off the power and ease the chisel free. (Check the chisel for damage before
continuing operation.)
7) Ensure that sparks from the process do not create a hazard to eyes or will ignite the environment.
8) Percussive tools shall not be used in potentially explosive atmospheres.
9) Pneumatically driven tools are not generally insulated from coming into contact with electric
sources. Be sure to avoid contact with wires or other possible current carrying sources.
10) The operator must check that no bystanders are in the vicinity.
11) Disconnect the power supply before servicing and changing of inserted tooling.
12) Release control device in case of interruption of energy supply.
13) Always keep the tool in a clean, dry place when not in use.
14) Do not hold tool near body when operating.
15) Keep a firm grip on tool during operation.
16) Do not chisel toward your body.
17) If a quick disconnect hose fitting is used, insert a whip hose between coupling and the tool.
18) Never carry a tool by the hose.
19) Never yank the hose to disconnect it from the air supply.
20) Keep hoses away from heat, oil, sharp edges and in good repair - inspect regularly.
21) Check to see that tool is securely fastened to air hose.
22) In air hoses larger than ½ inch, a safety excess flow valve must be installed at the source of the
air supply to reduce pressure in case of hose failure.
23) Before operating the tool, see that the retainer is installed and working to prevent attachments
such as chisels, or other implements from being ejected from the tool when operated. Because
these retaining devices receive substantial abuse and wear, they should be inspected regularly and
replaced when damage or wear is noted.
24) Never leave a tool attached to supplied air unattended. Avoid accidental actuation.
25) Always disconnect the tool from the air supply or shut off and drain the air hose prior to changing
chisels, or other implements.
26) Never point or direct a tool toward another worker or yourself.
27) When working in close proximity to other workers, suitable barriers may need to be erected
around work areas to protect workers from possible tool ejections or flying pieces from the removal
process itself.
28) Be sure to wear the properly fitted personal protective equipment required to guard against
operator injury.
29) Stay alert. Do not use the tool while under the influence of alcohol, drugs or medication.
