Hand-arm vibration syndrome is damage to the nerves and blood vessels of the hands and arms from regular use of vibrating tools. Tingling in the fingers is an early sign. For someone who uses a power tool now and then it passes, but for a worker who runs one for long hours it can last. Caught early, the damage can still reverse. Left to progress, it brings lasting numbness, fingers that turn white in the cold, and a weaker grip.
Who is at risk
A worker who regularly runs a vibrating tool, such as a grinder, sander or saw, for more than a few hours a day is at risk. So is one who runs an impact tool, such as a jackhammer, rivet gun or rotary hammer, for more than 15 minutes a day. Guiding a chisel, a socket, a bucking bar or a metal workpiece with a bare hand puts the vibration straight into the hand. Cold, wet hands, a tight grip and nicotine all add to the risk.
Cutting it at the source
Reducing the vibration and the time on the tool works best. Buy low-vibration tools when you replace old ones, and keep the tools on a regular maintenance schedule. Rotate workers off vibrating tasks so nobody runs the same tool all day. Look for another way to do the job, or a tool that vibrates less.
Hands, grip and gloves
Grip the tool as lightly as you safely can. Keep hands warm and dry, wear gloves in the cold, and warm the tool handles where you can.
Vibration-reducing gloves cut only part of the vibration. In lab tests reported in 2015, they cut the vibration reaching the palm by 5 to 20 percent with grinders and saws. With low-frequency tools, such as pavement tampers, some cut it slightly and some made it slightly worse. Treat gloves as an extra, never as the main control.
Watching for symptoms
Teach the crew the early signs, and ask anyone with tingling, numbness or white fingers to say so right away. Early disease can reverse, and the later stages don't.

FAQ
What are the first signs of vibration damage in the hands?
Tingling and numbness in the fingers. Later, the fingers can turn white in the cold and the grip weakens.
Do anti-vibration gloves work?
In lab tests reported in 2015, they cut the vibration reaching the palm by 5 to 20 percent with grinders and saws, and with low-frequency tools some made it slightly worse.
How long on a vibrating tool is too long?
More than a few hours a day on a vibrating tool, or more than 15 minutes a day on an impact tool.
