CALIFORNIA EXPANDED METAL PRODUCTS CO. November 16, 2011 Technical Services Department 263 N. Covina Lane City of Industry, CA 91744 (800) 416-2278 RE: LEED INFORMATION AND REQUIREMENTS RECYCLED CONTENT OF COLD-FORMED STEEL California Expanded Metal Products Company is proud to be a member of the U.S. Green Building Council and is committed to supplying products that contribute to the improvement of sustainable design, environmental performance, and economic impact for LEED New Construction and Major Renovations. CEMCO products and accessories contribute towards LEED credits in the following areas: LEED Materials & Resources MR Credit 2.1/2.2 - Construction Waste Management (Up to 2 Points) Since cold-formed steel is 100% recyclable, CEMCO products can contribute to this credit if the construction waste on the project is properly diverted from the waste stream. The contribution to this credit will vary by project and must be determined by the general contractor and/or sustainable design team. MR Credit 4.1/4.2 - Recycled Content (2 Points) The U.S. Green Building Council has determined that a total recycled content of 32.7% may be utilized without documentation. A typical breakdown content of our material is: Post Consumer: 25.5%, Pre-Consumer: 6.8% Note: While some CEMCO locations have a higher average recycled content, the USGBC default percentages above are recommended for your project calculations. Project specific recycled content can be provided upon request. MR Credit 5.1/5.2 - Regional Materials (2 Points) CEMCO is committed to the goal of increasing demand for building materials that are sourced, manufactured and distributed within the specified region; thereby reducing the environmental impacts resulting from transportation. While CEMCO has 4 manufacturing facilities serving the Western United States and the steel coil material that we utilize to cold-form our products is typically sourced within a 500 mile radius of your project; the majority of raw materials used in the production of steel come from various global sources, and most likely will not be extracted within 500 miles of your project. Note: Project specific submittal information can be provided upon requires for the above Materials and Resources categories.

Covina Lane, City of Industry, CA 91744 Pittsburg, California 1001-A Pittsburg Antioch Highway, Pittsburg, CA 94565 Denver, Colorado 490 Osage Street, Denver, CO 80204 Forth Worth, Texas 8600 Will Rogers Boulevard, Forth Worth, TX 76140 SS Credit 1: Site Selection (1 Point) Cold-formed metal framing is a light-weight alternative to conventional concrete construction. In some cases, the light weight system can reduce foundation requirements, which can minimize the building footprint. EQ Credit 3.1: Construction Indoor Air Quality Management (1 Point) Cold-formed metal framing products are considered inert, so materials will not release terpenes (hydrocarbons) to the indoor air or provide a food source for mold, bacteria or insects. Potential Innovations in Design Contributions (1 Point) CEMCO s ViperStud framing system provides increased strength capacity from lighter material that contributes to a lighter building footprint and reduction in energy to produce steel. (1 Point) An additional point may be earned if the recycled content value of the materials used on the project reaches the next threshold of 30% total recycled content. (1 Point) According to the International Residential Code, using metal framing can help reduce or eliminate the need for chemical based termite control, reducing the impact on the site and air quality.

SECTION 3: FIRE AND EXPLOSION HAZARD Non Flammable; Welding arc and sparks can ignite combustibles and flammable products. See Z49.1 referenced in Section 6. Health: 2 Flammability: 0 Reactivity: 0 Special Hazards: 4-Extreme 3-High 2-Moderate 1-Slight 0-Insignificant *-See Text SECTION 4: HEALTH HAZARD DATA Threshold Limit Value: The ACGIH recommended general limit for Welding Fume NOC-(Not Otherwise Classified) is 5 mg/m 3. ACGIH-1999 preface states that the TLV-TWA should be used as guides in the control of health hazards and should not be used as fine lines between safe and dangerous concentrates. See Section V for specific fume constituents which may modify this TLV. Threshold Limit Values are figures published by the American Conference of Government Industrial Hygienists. Units are milligrams per cubic meter of air. Effects of Overexposure: Electric are welding may create one or more of the following hazards: Fumes and Gases can be dangerous to your health. Common entry is by inhalation. Other possible routes are skin contact and ingestion. Short-term (acute) overexposure to welding fumes may result in discomfort such as metal fume fever, dizziness, nausea, or dryness or irritation of nose, throat, or eyes. May aggravate pre-existing respiratory problems (e.g. asthma, emphysema). Long-term (chronic) overexposure to welding fumes can lead to siderosis (iron deposits in lung) and may affect pulmonary function. Manganese overexposure can affect the central nervous system, resulting in impaired speech and movement. Bronchitis and some lung fibrosis have been reported. WARNING: This product, when used for welding or cutting, produces fumes or gases which contain chemicals known to the State of California to cause birth defects and, in some cases, cancer. (California Health & Safety Code Section 25249.5 et seq). Arc Rays can injure eyes and burn skin. Skin cancer has been reported. Electric shock can kill. If welding must be performed in damp locations or with wet clothing, on metal structures or when in cramped positions such as sitting, kneeling or lying, or of there is a high risk of unavoidable or accidental contact with work piece, use the following equipment: Semiautomatic DC Welder, DC Manual (Stick) Welder, or AC Welder with Reduced Voltage Control. Emergency and First Aid Procedures: Call for medical aid. Employ first aid techniques recommended by the American Red Cross. If breathing is difficult, give oxygen. If not breathing, employ CPR (Cardiopulmonary Resuscitation) techniques. In case of electrical shock, turn off power and follow recommended treatment. In all cases call a physician. SECTION 5: REACTIVITY DATA Hazardous Decomposition Products: Welding fumes and gases cannot be classified simply. The composition and quantity of both are dependent upon the metal being welded, the process, procedure and electrodes used. Other conditions which also influence the composition and quantity of the fumes and gases to which workers may be exposed include: coatings on the metal being welded (such as paint, plating, or galvanizing), the number of welders and the volume of the worker area, the quality and amount of ventilation, the position of the welder s head with respect to the fume plume, as well as the presence of contaminants in the atmosphere (such as chlorinated hydrocarbon vapors from cleaning and degreasing activities.) When the electrode is consumed, the fume and gas decomposition products generated are different in percent and form from the ingredients listed in Section 2. Decomposition products of normal operation include those originating from the volatilization, reaction, or oxidation of the materials shown in Section 2, plus those from the base metal and coating, etc., as noted above. Reasonably expected fume constituents of this product would include: Primarily iron oxide; secondarily fluorides and fluorides and complex oxides of silicon, sodium and titanium. Maximum fume exposure guidelines for this product (based on manganese content) are 1.5 milligrams per cubic meter. Gaseous reaction products may include carbon monoxide and carbon dioxide. Ozone and nitrogen oxides may be formed by the radiation from the arc. Determine the composition and quantity of fumes and gases to which workers are exposed by taking an air sample from inside the welder s helmet if worn or in the worker s breathing zone. Improve ventilation if exposures are not below limits. See ANSI/AWS F1.1, F1.2, F1.3, F1.4, and F1.5, available from the American Welding Society, 550 N.W. LeJune Road, Miami, FL 33126.

Box 371954, Pittsburgh, PA 15250-7954 for more details on many of the following: Ventilation: Use enough ventilation, local exhaust at the arc, or both to keep the fumes and gases from the worker s breathing zone and the general area. Train the welder to keep his head out of the fumes. Keep exposure as low as possible. Respiratory Protection: Use respirable fume respirator or air supplied respirator when welding in confined space or general work area when local exhaust or ventilation does not keep exposure below TLV. Eye Protection: Wear helmet or use face shield with filer lens shade number 12* or darker. Shield others by providing screens and flash goggles. Protective Clothing: Wear hand, head, and body protection which help to prevent injury from radiation, sparks and electrical shock. See Z49.1. At a minimum this includes welder s gloves and a protective face shield, and may include arm protectors, aprons, hats, shoulder protection, as well as dark substantial clothing. Train the welder not to permit electrically live parts or electrodes to contact skin or clothing or gloves if they are wet. Insulate from work and ground.
