The Things To Avoid In VIBRATION.

The Things to Avoid in VIBRATION


Vibrations cause workplace health problems by using vibrating work tools. When using these tools, vibrations are transmitted to the worker's body, hands, and arms, causing arm and whole-body vibration (WBV).

Arm vibration is caused by vibration transmitted to workers' hands and arms when using hand-held power tools such as impact drills, chain saws or hand-guided tools such as grinders, hand, etc. . It can cause the syndrome of arm vibration and carpal tunnel syndrome.


The Things to Avoid in VIBRATION


Symptoms of Hand Arm Vibration Syndrome (HAVS):


* Intense pain in the hands and arms


* Disabling state that affects the nerves, blood vessels, muscles and joints.


* Tingling and numbness in the fingers


* Reduces grip strength and sense of touch


* Affects the blood circulation


Symptoms of Carpal tunnel Syndrome (CTS):


* You may feel tingling and numbness in your fingers or hand, especially the thumb and forefinger, middle finger or ring finger, but not your little finger.

* You may feel weakness in your hand and a tendency to drop objects.





Causes of HAV:

* Prolonged and regular exposure to vibration can damage nerve endings and affect blood circulation.

* The vibrations in the arms are seriously disabling and can affect your work and your social life.


Precautions for HAV:


* If you feel tingling in your hands, stop working and rest

* Always keep your hands warm, exposure to cold can accelerate arm-hand vibration syndrome

* Use anti-vibration gloves, it also keeps the hands warm

* Avoid working permanently on vibrating equipment

* Maintain and repair tools with manual guidance

* Take care not to grasp too much the tools

* Set up a rotation of tasks and time limits for activities highly exposed to vibrations







Whole body vibration (WBV) mainly affects drivers of off-road vehicles, such as dumpers, excavators, tractors, etc. as gantry cranes.

WBV is mainly associated with lower back pain. However, back pain can also be caused by other factors, such as manual manipulation and postural tension, while exposure to vibration and shock can be painful for people with back problems.

Causes of WBV:


* Wrong control design, which prevents the driver from easily using the machine or vehicle or seeing properly without twisting or stretching.

* Improper adjustment by the driver of the seat position and hand and foot controls, so that it is necessary to continuously twist, bend, bend and stretch to operate the machine.

* Sitting for long periods without being able to change position.

* Bad driving posture

* Excessive exposure to shocks and jolts.

* Ride or jump several times in a high cabin or where it is difficult to enter and exit.

* The risk increases when the driver or operator is exposed to two or more of these factors simultaneously.




Precautions for  WBV:

* Reduce continuous use on vibrating equipment by providing regular intervals.

* Use rubber mats and provide shoes with thick rubber soles

* Maintain pavement level, fill potholes and remove debris

* Maintain and repair machine and vehicle suspension systems, regularly check tire pressure and suspension seats to avoid excessive vibration.
