hazard for decades, the extent and variety of the symptoms have
only recently become appreciated by medical professionals. Even today, HAVS is known to be an incredibly complex condition that’s still not completely understood, although the symptoms are usually easily diagnosed once a patient’s work history is taken into consideration.
The exact underlying mechanism responsible for HAVS is generally believed to be a disruption in the flow of oxygenated blood through the body’s vascular system. This is particularly pro- nounced at the extremities most associated with HAVS symptoms.
Sustained exposure to vibrations can eventually damage the tissues themselves where the condition may become irreversible. As stated, some of the early onset HAVS symptoms include
tingling and numbness, which may or may not dissipate after a relatively short amount of time. With sustained vibration exposure, however, tingling and numbness can give way to more ominous symptoms. Visual manifestations can include a noticeable change in skin color, or whitening, of the extremities, which usually occurs in combination with a heightened sensitivity to hot and cold temperatures. In fact, HAVS is more likely to

even gangrene.
Now that you’re sufficiently terrified of the prospect of having
your gangrenous limbs dropping off because you ran your circular saw one time too many, there are steps you can take to decrease your chances of developing HAVS.
Assessing the Risk of Hand-Arm Vibration
Companies may perform an audit of their work environments to determine whether vibration equipment poses a risk to worker health and how significant that risk may be. Calculating those risks takes into account the level, or vibration amplitude, of various equipment that may contribute to HAVS.
The threshold vibration value is deemed the acceptable risk level workers can be exposed to with the least chance of developing HAVS. Many tool and equipment manufacturers disclose and provide vibration emission safety guidelines with their products, making it easier for businesses to research and calculate their associated risks.
In cases such as sustained jackhammer operation, for example, an individual may suffer a loss of grip strength and decreased
