As a gift for new users, we suggest the starter kit, which includes everything they need ($49.99 on Amazon). They can play Minecraft, use it to run holiday lights, or make their own photo booth. The amazing Raspberry Pi is a tiny computer that is ready to do just about anything teachers might want. Teachers can use it with conductive paint to create music or measure distance, rate, and time for great science lessons ($49.95 at Amazon). This little device turns everyday objects like bananas into touchpads (above) and connects them to the internet, making it a must for artists, engineers, and makers-and anyone with a sense of whimsy. Simple to use, Makey Makey is great for newbie nerds. And for extra pizzazz, you can get creative with the presentation. You have a little more creative freedom with art or science teachers, but there are some school supplies that are universally appreciated. We also heard that school supplies are always a welcome gift, for teachers of any subject or grade level. And if you include a handwritten note of appreciation and/or a piece of handmade art from your child, so much the better. Whether you go with something mainstream like Amazon, Target, Starbucks, or iTunes, or something more personalized like a local restaurant or gift shop, gift cards are the educators’ jam-anything you do to help boost their spending power is going to be a hit. Okay then, what is a well-meaning parent to do? For Anyone on Your ListĪccording to our (very) informal survey, there is one sure-fire holiday gift idea: gift cards. “I have no room, and, after 20 years of teaching, these go straight to Goodwill.” “Or holiday gnomes, ornaments, or snow globes,” chimed in another. While the tables represent only a small fraction of the total number of companies in their respective industries, the results can provide insight into where workplace Cr(VI) exposure is occurring in the United States.“Please, please no more coffee mugs,” begged one elementary teacher. The industry profile tables in this website are based on Cr(VI) air samples taken during OSHA inspections from 2006 to 2009. This data provides a snapshot of industry sectors and business subcategories where levels of airborne Cr(VI) have been found. This database does not include worksite inspection sample results from many of the 26 States that operated OSHA-approved State Plans or OSHA consultation visits. OSHA provides a publicly available Chemical Exposure Health Database which includes industrial hygiene sample results from OSHA inspections. Industrial processes that involve chromium can result in worker exposure to toxic hexavalent chromium. Where is exposure to hexavalent chromium occurring? Use of pigments, spray paints and coatings.Welding and other types of "hot work" on stainless steel and other metals that contain chromium.Workplace exposures occur mainly in the following areas: Many workers in a variety of occupations are potentially exposed to Cr(VI) in the United States. The Cr(VI) compound chromic acid is used to electroplate chromium onto metal parts to provide a decorative or protective coating. It also may be used as an anticorrosive agent added to paints, primers, and other surface coatings. Cr(VI) compounds may be used as pigments in dyes, paints, inks, and plastics. A major source of worker exposure to Cr(VI) occurs during "hot work" such as welding on stainless steel and other alloy steels containing chromium metal. Chromium metal is added to alloy steel to increase hardenability and corrosion resistance. In addition, it targets the respiratory system, kidneys, liver, skin and eyes. It is usually produced by an industrial process. Hexavalent chromium is one of the valence states (+6) of the element chromium.
