Wet Methods - Water
Water is used to suppress the dust produced by pneumatic, hydraulic, or gasoline-powered saws. Water is normally applied to the blade through one or two nozzles. Water may be supplied from a portable pressurized tank or from a hose. A flow rate of 0.5 liters (17 ounces) of water per minute is recommended to suppress dust. Less water is not as effective, but more water will not increase dust control. Electric-powered saws with water attachments are also widely available.
