![]() ![]() Few compounds of aluminium are classified in Annex 1 of the European Economic Union Council (EEC) Directive 67/1548, with aluminium powder and sodium aluminium fluoride (cryolite) as examples of exceptions, as well as compounds in which the anion renders them reactive such as aluminium phosphide. Aluminium oxides, hydroxides and oxyhydroxides occur in numerous crystallographic forms, which exhibit different surface properties. Like Mg 2+ and Ca 2+ ions, Al 3+ in most situations seeks out complexing agents with oxygen-atom donor sites such as carboxylate and phosphate groups, including in biological systems. The solubility of aluminium salts is governed by pH, because the aluminium(III)-cation (Al 3+) has a strong affinity for the hydroxide ion, which promotes precipitation. Most aluminium compounds are solids exhibiting high melting points. on May 14, 2013, and covered a swatch nearly 10 miles long and 1.5 miles wide before being declared 100% contained on May 15 at 9 p.m.Ĭheck current fire danger, wildfire reports and burning restrictions on the DNR website.Identity, Physical and Chemical Properties, Analytical MethodsĪ compendium is provided of aluminium compounds used in industrial settings, and as pharmaceuticals, food additives, cosmetics and as other household products. An estimated 350 structures were saved due to fire control efforts. May 14 marked the 10-year anniversary of the Germann Road Fire in Douglas and Bayfield counties, which burned 7,499 acres and destroyed 104 structures, 23 of which were residences. Delay having campfires until the evening hours as fire conditions tend to improve keep them small and contained. Make sure they are completely extinguished before leaving them unattended.įire control officials are pre-positioning equipment for rapid response including two Wisconsin Army National Guard Black Hawk helicopters stationed in Rhinelander and two single engine air tankers in Solon Springs.Secure trailer chains to keep them from dragging.Operate equipment (chainsaws, off-road vehicles, lawn mowers, etc.) early in the morning or late in the day to avoid sparks at peak burn hours.Avoid outdoor burning until conditions improve. Burn permits for debris burning are currently suspended in numerous counties.The current fire danger in the southern half of the state is low as vegetation has greened up and the area has received periodic rain over the last few weeks. ![]() Warm temperatures, dry air and windy conditions in the forecast across the north will keep fire danger elevated throughout the week until a chance of rain moves in on Thursday night. Most of these were related to debris burning, which is the single largest cause of wildfires in Wisconsin. The DNR has responded to 281 wildfires burning more than 3,358 acres so far this year. Combined with very low humidity and the potential for winds, fires could spread out of control rapidly at this time.Īreas with VERY HIGH fire danger today include Ashland, Bayfield, Burnett, Douglas, Florence, Forest, Iron, Langlade, Lincoln, Marinette, Oconto, Oneida, Polk, Price, Sawyer, Vilas and Washburn counties.Īreas with HIGH fire danger include Barron, Chippewa, Marathon, Menominee, Rusk, Shawano and Taylor counties.Īll DNR issued annual burning permits for debris piles, burn barrels and prescribed burns are suspended today in 21 counties where the DNR has burning permit authority. Additionally tree growth in this part of the state is at a volatile stage. The sandy pines areas of northern Wisconsin are always the slowest to green up. A fire weather watch is in effect and the DNR and partners at the National Weather Service (NWS) are closely monitoring the situation. MADISON, Wis. – The Wisconsin Department of Natural Resources (DNR) is asking the public to avoid burning due to critical fire danger across northern Wisconsin.
