Environmental Considerations of Treated Wood National Park Service – Pacific West Region
Environmental Considerations of Treated Wood National Park Service – Pacific West Region Overview In support of the mission of the National Park Service, making wise decisions about using wood treatments will help protect the natural areas and biodiversity of our parks, and the health of our employees. Preservative-treated wood’s most important benefit is its resistance to water, fungal, and insect damage. Extending the life of wood products reduces the demands on forests for replacement lumber and reduces maintenance and replacement costs. Historic wooden structures that must be repaired with compatible materials or replaced with in-kind materials make durability even more important. Treated woods are nearly impervious to rot and insects, making them good for outdoor use. Wood treated with chromated copper arsenate (CCA) poses certain environmental and health risks, including the leaching of chemicals such as arsenic and chromium into the environment and workers’ risk of exposure to hazardous chemicals. Disposal of treated wood also proves to be an issue, particularly disposal by incineration. Due to these concerns, manufacturers of treated wood and the EPA reached an agreement to end the sale of CCA-treated wood for most lumber products, effective January 1, 2004. The following offers less-toxic alternatives to CCA, handling and use precautions, and other recommendations when considering using treated wood. Due to the toxicity and potential effects on health and the environment, the Presidio Trust implemented a policy on the use of pressure treated lumber. Standard operating procedure now prohibits the use of CCA, ACZA, CZC, ACC, and Pentachlorophenol. All dimensional lumber is now treated with ACQ as an alternative. -
Using Veneering Tools
Using veneer hand tools Veneer Tape Dispenser A gum tape dispenser that will take 3/4”wide gum tape is excellent for securing veneer seams together. A manual pull and tear machine which has a brush or sponge that will moisten tape (25 gram weight). It is indispensable for any shop that works with veneer. A sponge in a cup works well for moistening short lengths of tape for smaller projects. Veneer Gum Tape 25 to 30 gram (non-perforated) veneer tape that has water activated hide or vegetable glue is ideal for veneering. It is cut to length, moistened with a sponge or with the tape dispenser wetting system, placed over the veneer seam or joint, and smoothed or burnished down with a brush or rag to secure it firmly onto the veneer. It is used for final assembly of veneer joints in decorative veneering, in order to create a single skin or sheet of veneer. Ideally, after the gum tape is applied over the joints, the assembled veneer skin gets placed between two plattens to insure that the moisture from the gum tape does not warp the veneer until it dries. This complete skin will then be glued onto a foundation or core of smooth plywood or MDF, with the gum tape side exposed. After the veneer is glued to the core with a mechanical or vacuum type veneer press, the tape is removed by moistening and peeling it off with a sharpened flexible putty knife, or sanded off the veneer with a belt, stroke or random orbital sander. -

Hardwood Veneer Lesson Plan
Hardwood Veneer Lesson Plan Keywords: veneer, saw log, furniture, woodworking Lesson Plan Grade Level: 6th- 8th Total Time Required For Lesson: 50 minutes Setting: Classroom Subjects Covered: Science Topics: Wood Products, Manufacturing Goals For The Lesson: Students will be capable of identifying and discovering the uses of hardwood veneer. Students will gain an understanding of the process of manufacturing hardwood veneer. Materials Needed: Hardwood Veneer fliers (From The Woods Series) Hardwood Veneer Pretest Hardwood Veneer Posttest Paper Pencils Appendix 1 Ruler with millimeters (calipers will also work if available) Sample of veneer (contact furniture stores, wood makers, veneer mill etc. for samples) State Standards Addressed: E&E Standards: 4.2.7, 4.8.7 Teaching Model: Experiential Learning Model (Experience, Share, Process, Generalize, Apply) Methods: Preparation: Read through the entire lesson to ensure your understanding of the material and activity. After reading the lesson, walk through the school and identify products with hardwood veneer. Determine locations where the students will be permitted to walk through during class time. Doing The Activity: Introduction to the lesson: Demonstrate 0.6 millimeters to the students, on a ruler. Ask the students to describe objects/ products that may have the measurement (such as a thick piece of paper). Explain to the students that they will be learning about a material that can have a 0.6 millimeter measurement and yet still create beauty. Steps: (Experience and Share Stages 30 minutes) 1. Administer the pretest to the students; explain that the purpose of the pretest is test knowledge the students already have acquired on the subject. -
Sawdust Mulches for Larger Crops, Better Soils
C3DQ5/ Sawdust Mulches for Larger Crops, Better Soils Edited by J. L. Overholser Report No. G-5 July 1955 4- OREGON FOREST PRODUCTS LABORATORY State Board of Forestry and School of Forestry, Oregon State College, Cooperating Corvallis OREGON FOREST PRODUCTS LABORATORY was THEestablished by legislative action in 1941 as a result of active interest of the lumber industry and forestry- minded citizens. It is associated with the State Board of Forestry and the School of Forestry at Oregon State College. An Advisory Committee composed of men from representative interests guides the research program that is directly pointed toward the fuller utilization of Oregon's forest resources. The following men con- stitute the present membership of the Advisory Com- mittee: PAUL PATTERSON, Governor .Chairman ROBERT W. COWLIN Pacific Northwest Forest and Range Experiment Station CHARLES W.

Overholser Large-volume use of sawdust for a mulch on various crops may result in increased yields as shown in field tests at Corvallis during the last 6 years. The Departments of Horticulture, Soils and Bacteriology at Oregon State College have cooperated with the Oregon Forest Products Laboratory in comparing sawdust with straw, leaf mold, and hay as mulches and also where cultivated into the soil for growing strawberries, blueberries, cane fruits, and annuals such as corn, tomatoes, beans, and cabbage. -
