...were warned of the danger but did nothing. In the U.S. those who had the power to take action instead engaged in self-delusion: the Reagan Administration at first dismissed the ozone threat as a nonissue, while Du Pont and other manufacturers underestimated future sales of CFCs, making the hazard seem minimal...
...numerous diseases often carried in feces made these specimens a health hazard, and many workers, University mail employees and U.S. Postal deliverers were not aware of the contents of the envelopes they were handling, the former employee said...
...thrills of a more perilous kind: avalanches, known to mountaineers as the "white death." Avalanches have already claimed 19 lives in the U.S. this winter. And last week five Coloradans, who lost their way in a subzero Aspen blizzard, were almost added to that number, raising awareness of the hazard...
...poker chips. This dangerous situation commonly occurs in Colorado, where temperatures are very cold (snow crystals bond most readily close to their melting point). The shape of the crystals is important too. A layer of graupel -- soft hailstones that behave like miniature ball bearings -- substantially increases the avalanche hazard. In essence, graupel provides a high-speed conveyor belt for the layers of snow deposited on top. Another kind of trouble comes in the guise of sugar snow -- coarse grains created when water vapor freezes and refreezes. In Colorado a layer of sugar snow formed early in the season...
...skiers who stick to groomed runs, avalanches pose little hazard. Most major ski resorts operate military-style control programs that rely on explosive charges to trigger slides on avalanche-prone slopes before skiers head for the lifts. But increasingly, skiers are stepping beyond the boundaries set by resorts -- prompted in part by long lift lines and the high cost of lift tickets as well as the thirst for adventure. "What they don't realize," says Dale Atkins, who forecasts avalanches for the state of Colorado, "is that once they cross under that quarter-inch rope, they've gone from...
