vibrations and noise can have devastating long-term consequences for an operator. For example, prolonged exposure to vibrations can lead
to hand-arm vibration syndrome (HAVS) which can result in a loss of sensation in the hand. At the same time, extremely loud noises or
continued exposure to loud noises can result in loss of hearing.
The tool’s vibration level and the length of exposure time are the two key factors that indicate whether an operator will be at risk from
HAVS. Vibration and noise can both be minimized by choosing tools with low levels, evaluating the work pattern and wearing appropriate PPE,
such as ear protectors.
2. Check that the tools have appropriate safety features:
Grinders – Key safety features on these tools are overspeed shut-off functions, autobalancers and guards. The first – overspeed
shut off –
prevents a grinding wheel from speeding faster that it should, and therefore it reduces the risk of disc burst which would ultimately injure
the user. Secondly, autobalancers stabilize
a tool, greatly reducing vibration. Finally, guards protect the operator from any shrapnel in case the disc breaks apart.
Impact wrenches – An important feature to consider is the torque limited function which enables torque level control,
mainly on tightening applications where torque control is essential, such as tire changing or shipyards. Tools
whose torque is limited by
an air flow modification have lower vibration than those with a mechanical modification.
3. Perform regular maintenance
servicing is vital when ensuring the safety of equipment as a tool that is well looked after and properly maintained will have less risk
of failing. Maintenance
should be carried out according to the tool’s manual,
for example, components that wear most frequently and therefore need maintaining in grinders are the blades and bevel gears. Blades should
be inspected every 500 hours, and the interval for bevel gears is every 1,000 – 2,000 hours depending on the tool.
4. Know how to use the tools safely
follow manufacturers’ recommendations and best practice on tool usage. Ensure operators are fully trained to use equipment safely and to
follow the company’s agreed safety procedures. Furthermore, make sure you are using the right tool and abrasive for the job.
5. Wear appropriate PPE
protection equipment (PPE) helps to shield the operator against potential hazards. It is critical that operators always use all
recommended safety equipment when operating pneumatic tools, including sturdy gloves to protect hands from the elements, helmets and
safety goggles in case of any debris, and ear protectors for noise.
6. Make sure the environment is safe
the environment surrounding the job and ensure you take appropriate precautions. For example, is it a confined space, or is the job at
height? Grinding can create fine dust particles, which if inhaled can cause health and safety issues for the operator. Therefore, always
grind in a well-ventilated space. Also, always ensure that the workpiece is secure, and you have a stable operating position.
7. Ensure you have a good air line set up
Think about the whole tool system including the air line. All pneumatic tools require clean, lubricated air and a dynamic pressure of 90 PSI
(6.3 bar) to work safely. If the pressure is any higher than this, it could negatively affect the tools’ lifespan and risk operator’s
safety. Air pressure can be adjusted with an FRL (filter, regulator, lubricator) so it is important to include one in the air system near
By considering these seven points you will improve safety associated with using tools in the workplace, therefore protecting operators. An
additional benefit to these responsible practices is that you will improve efficiency too!

reputation for quality and reliability.We look after all things compressed air for your business!
Reciprocating, Screw, air compressors
An extensive line of air treatment components
Ash Air's range of Chicago Pneumatic, Alup, Pneumatech, and Quincy compressors are used extensively around the world in industries
ranging from oil and gas to food, automotive and farming, and we bring you these world class compressors here in the land of the long white
cloud.Our technicians are compressed air equipment experts and are dedicated to addressing customer needs. Supported by a 13 locations
nationwide, Ash Air offers one of the widest selections of compressed air equipment and parts available today in New Zealand.
Reliability and Efficiency
With Ash Air compressors, you can count on reliability and high performance for even the most demanding applications. We focus our
efforts on the following:
Air is always contaminated with solid particles such as dust, sand, soot, salt crystals and water as it leaves the compressor. An effective
compressed air treatment system lowers the dew point of the air and takes out the elements that may harm equipment downstream of the
compressor and dryer
The ambient temperature in an air compressor’s environment can greatly affect your air compressor’s performance. All air compressors will
generate some amount of water, but depending on inlet air conditions some can produce large amounts of water.
