...nastiest microorganisms, though, are in BSL4. The entire lab is kept at negative air pressure, so if a leak somehow develops, air will flow in rather than out. Researchers generally work in pairs; if one is inadvertently exposed to a microbe, the other can take action. They wear airtight suits hooked directly to a source of clean air. There is no eating, drinking or even going to the bathroom anywhere within BSL4. On the way out, everyone takes a chemical decontamination shower inside the safety suit, followed by a conventional shower. All clothing used in the lab is incinerated...
...bomb, as might bored, poorly paid and poorly trained operators of X-ray machines. At some U.S. airports, including Kennedy, checked-in luggage for international flights is sniffed by specially trained dogs or scanned by electronic vapor-particle detectors that can locate explosives. But if the explosives are in airtight containers, they may be missed...
...nuclear plants, to find out how many have been moving fuel in violation of NRC standards. The results will be in by April, along with a menu of fuel-pool safety recommendations. (By using a technique called dry-cask storage, utilities could empty their pools and warehouse rods in airtight concrete containers, reducing risk. In the past, the NRC has ruled that the process isn't cost effective...
...Pacific area and Russia that are working together to advocate safe disposal of these hideous weapons. The Army has the capability today to eliminate the risk of continued storage of its aging, leaky M-55 rockets by draining the nerve agent from them and storing it in safe, airtight bulk containers. Unfortunately, the Army has been more interested in pushing forward its incineration program than in protecting the safety of our communities. I live near Richmond, Kentucky, the site of one of the Army's nine chemical-weapons stockpiles, and am therefore very concerned about their safe, prompt disposal. MELISSA...
When the hour of execution finally arrives, the killers will be transported from their bunkers in airtight, fire-resistant containers. At the death house, they will be loaded onto conveyor belts, stripped by remote-controlled machines, then plunged down a chute into a 2700-degree F inferno. Anything that comes into contact with these untouchables during their final transport--wraps, pallets, gloves--will be incinerated as well. Thus America will bid an unsentimental farewell to 30,600 tons of chemical weapons...
