A study to estimate occupational exposure to inhalable wood dust by country, industry, the level of exposure and type of wood dust in 25 member states of the European Union (EU-25) found that in 2000–2003, about 3.6 million workers (2.0% of the employed EU-25 population) were occupationally exposed to inhalable wood dust.
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 ...
During the stages of wood processing, wood dust is generated.'Wood dust' is "any wood particle arising from the processing or handling of woods." [5] Sawing, routing, sanding, among other activities, form wood dust, which can then become airborne during the process of dust removal from furniture, maintenance, or equipment cleanup.
The Wood Machinery Manufacturers of America's Industrial Dust Task Force has been following the Occupational Safety and Health Administration on the new rules since October 2009. The goal is to ensure that companies follow proper dust collection procedures. Wood Machinery Manufacturers of America (WMMA) fully supports efforts to protect workers ...
A slab of pykrete Pykrete is made of 14% sawdust and 86% water by mass.. Pykrete (/ ˈ p aɪ k r iː t /, PIE-creet) [1] is a frozen ice composite, [2] originally made of approximately 14% sawdust or some other form of wood pulp (such as paper) and 86% ice by weight (6 to 1 by weight).
Dust is made of fine particles of solid matter. [1] On Earth, it generally consists of particles in the atmosphere that come from various sources such as soil lifted by wind (an aeolian process), volcanic eruptions, and pollution. Dust in homes is composed of about 20–50% dead skin cells. [2]
The dust produced when cutting or sanding wenge can cause dermatitis similar to the effects of poison ivy and is an irritant to the eyes. The dust also can cause respiratory problems and drowsiness. [citation needed] Splinters are septic, similar to those of greenheart (the wood of Chlorocardium rodiei).
When free hydroxyl groups are transformed to acetoxy groups, the ability of the wood to absorb water is greatly reduced, rendering the wood more dimensionally stable and, because it is no longer digestible, extremely durable. In general, softwoods naturally have an acetyl content from 0.5 to 1.5% and more durable hardwoods from 2 to 4.5%.
