Proper dust collection and air filtration is important in any work space. Repeated exposure to wood dust can cause chronic bronchitis, emphysema, "flu-like" symptoms, and cancer. Wood dust also frequently contains chemicals and fungi, which can become airborne and lodge deeply in the lungs, causing illness and damage. [9] [10]
Wood-dust concentrations vary with type of dust extraction, amount of wood removed, and type of sander (Thorpe and Brown 1994). [2] For electric belt sanders used to sand dowels , total dust concentrations ranged from 0.22 mg/m with external dust extraction to 3.74 mg/m without extraction, and concentrations of respirable dust ranged from 0.003 ...
Sawdust (or wood dust) is a by-product or waste product of woodworking operations such as sawing, sanding, milling and routing. It is composed of very small chips of wood . These operations can be performed by woodworking machinery , portable power tools or by use of hand tools .
Apart from structural wood preservation measures, there are a number of different chemical preservatives and processes (also known as timber treatment, lumber treatment or pressure treatment) that can extend the life of wood, timber, and their associated products, including engineered wood. These generally increase the durability and resistance ...
Extremely fine wood dust is liberated when sanding wood. All wood dust is hazardous, can cause respiratory problems. For this reason, many woodburners wear quality dust masks/respirators while power carving, and use a good dust collection system to prevent indoor air pollution. There are serious risks associated with burning pressure-treated wood.
Reverse pulse-jet dust collectors can be operated continuously and cleaned without interruption of flow because the burst of compressed air is very small compared with the total volume of dusty air through the collector. On account of this continuous-cleaning feature, reverse-jet dust collectors are usually not compartmentalized.
