Sander dust

Wood-fired power boilers are generally found at the mills where wood products are manufactured. They are fired with waste materials from the process, such as "hogged wood," sander dust, sawdust, bark, or process trim. Little information is available on gaseous emissions from wood-fired boilers, but extensive tests of particulate matter emissions are reported (19). These emissions range from 0.057 to 1.626 gm per dry standard cubic meter, with an average of 0.343 reported for 135 tests. Collection devices for particulate matter from wood-fired boilers are shown in Table 30-21.

The filler is usually "furafil," (a ligno-cellulose by-product of furfural production of Quaker Oats Company), Douglas fir or alder bark, wood particleboard sander dust and/or attapulgite clay. A sulfite paper mill lignin is also used as a filler in the Northwest. Between 50,000 and 60,000 tons of filler were used in phenolic glue mixes per year. 

All of the products, with the possible exception of particleboard wood sander dust, yield varying degrees of thixotropic properties which permit easy application, yet fixed in a consistent pattern after application.

Wood residues currently burned in commercial units include plywood trim and sander dust, wood shavings, whole log chips, bark, and log yard wastes. Coal or agricultural residues can also be burned in the system either separately or in combination with other fuels.

Three kinds of processes have been invoked for forming chondrules melting of dust aggregates (generally considered to be the standard model), condensation of melts, or melts and crystals (Ebel and Grossman, 2000 Krot et al., 2001d), and impacts into solid or partly molten asteroids (e.g., Symes et al., 1998 Sanders, 1996). As discussed above, we believe that all three processes formed chondrules, and that the standard model cannot account for olivine-rich and pyroxene-rich chondrules.

When they had the home renovated, surfaces were restored by removing the paint down to the bare surface on floors and woodwork and recoating with new varnish. Ceilings were repaired, and wallpaper and paint were removedfrom a number of walls. Two workers used rotary power Sanders, hand sanders, scrapers, heat guns, and chemical paint strippers. The family left the house during most of the renovation work, but returned after it was only partially completed. There was dust throughout the house. 

Sanding should also be wet, to minimize the dust generated, except for work near electrical circuits. Electric sanders should not be used without HEPA vacuum filter attachments to catch and filter the dust that is created. Respirators are recommended. 

Sanding is the greatest source of lead dust. Electric sanders, grinders, or planes are sometimes used after scraping to remove any paint that scraping did not get off. Although this method is simple and inexpensive, it is not recommended because it creates large amounts of toxic lead dust, unless a vacuum attachment connected to a HEPA-vac is used with the Sander. 

Even when sanding is done WITH the recommended attachment, lead dust can escape if the Sander is not kept perfectly flush with the surface at all times. Sanding should only be done on totally flat surfaces. 

There are several different renovation methods that should be incorporated into the project to limit the amount of dust created. Power tools, such as sanders, grinders, or needle guns, should be equipped with high efficiency particulate air (HEPA) attachments to capture any dust from these operations.

Do not use a belt-sander, propane torch, heat gun, dry scraper, or dry sandpaper to remove lead-based paint. These actions create large amounts of lead dust and fumes. Lead dust can remain in your home long after the work is done. 

REMOVE THE OLD FINISH. Wipe down the piece with a damp rag to remove any accumulated dust and dirt. Follow the instructions in How to Strip Paint on page 240, and opt for a gel and not a liquid stripper (it is prone to drain off furniture before it can work properly). Use a putty knife and steel wool to remove as much paint or varnish as possible. If you don t want to use a chemical stripper, reach for the random orbital sander (or spend hours building muscle and character sanding by hand). 

Orbital sander. The genius of a random orbital sander is a sanding belt that moves so that any single grain on the belt never travels the same path twice. The result is a much smoother finish than a belt or disc sander, but it also means you can t remove as much material as quickly. A palm sander will handle most basic needs, and whatever model you choose, make sure it has dust control—either self-contained or with a hose connection to your wet/dry vac. 

A vacuum applied to such power tools as needle guns (Kurt, 1991) and others (Bloemke, 1991) eliminates most of the dust from the working environment when cleaning steel sfructures however, power tools (needle guns, brushes, sanders, and others) have difficulty with nonplanar surfaces, sueh as comers and edges, and wood is particularly vulnerable to harsh meehanieal treatment, so careful consideration should be given before using power tools.
