Legislator Wants Cancer Warnings For Cell Phones
Cytalk writes "A Maine legislator wants to make the state the first to require cell phones to carry warnings that they can cause brain cancer, although there is no consensus among scientists that they do and industry leaders dispute the claim. The now-ubiquitous devices carry such warnings in some countries, though no US states require them, according to the National Conference of State Legislators. A similar effort is afoot in San Francisco, where Mayor Gavin Newsom wants his city to be the nation’s first to require the warnings."
Ironically, those LN2 tanks DO present a danger that is worth warning about. But the warning isn't that "nitrogen may be present," obviously. The issue is that a leaky LN2 tank in an enclosed space may wind up making nitrogen the ONLY gas present, which is extremely hazardous. You can pass out without feeling anything abnormal in advance, and then quickly suffocate. Nitrogen asphyxiation has been advocated as an execution method for this very reason, in fact. Two people died in a nitrogen asphyxiation accident at NASA some time ago. The second tried to rescue the first without first understanding what went wrong, and then succumbed himself (if I am remembering the story properly).
