China Pneumatic Corp. provides the world's most innovated air saw design available on the market with ergonomically enhanced design and extreme low vibration that helps to reduce the Hand arm vibration syndrome (HAVS) which caused by excessive, long-term exposure to working with tools that vibrate.
How does the tool vibration affect your health?
Excessive exposure to vibration can cause injuries to:
Blood vessels in your hands and fingers
Sensory nerves in your hands and fingers
Bones and joints in your hands, wrist and possibly elbow and shoulder
Muscles in your hand and forearm
Recovery of the damage after you stop any exposure is slow or may appear permanent.
What are the symptoms of HAVS?
HAVS causes problems with your blood circulatory system:
Periodic attack when fingers, or parts of them, turn white especially when exposed to cold. This is known as "vibration white finger" and indicates that the supply of blood to that area has been temporarily stopped. Those areas that turn white will lose any sensation.
Throbbing pain in fingers when the blood returns during recovery from an attack of "vibration white finger"
HAVS can also result in sensory nerve damage:
Tingling sensation and pins and needle in hand and fingers
Numbness in the hand and fingers
Your ability to detect touch and temperature is reduced in your fingers
You find it difficult to carry out delicate jobs with your hands
Other symptoms of HAVS include:
Damage to muscle, bone and joints
Loss of strength in your hand
Pain in the hand, wrist and arm
What tools can cause HAVS?
Tools usually associated with HAVS include:
Hammer drills, scrabblers, needle guns, chain saws, vibrating compactors, riveting and chipping hammer, bolsters tampers, road drills, concrete breakers, hand-held sanders, sanders, angle grinders, power hammers, chisels, powered lawnmowers, strimmers, brush cutters, nut runners, power screwdrivers.
