The Occupational Safety and Health Administration (OSHA) has issued two new educational resources to help protect workers from mercury exposure while crushing and recycling fluorescent bulbs. Compact fluorescent bulbs are more efficient than incandescent bulbs, but the shift to energy-saving fluorescents, which contain mercury, calls for more attention to workers who handle, dispose of, and recycle used fluorescent bulbs.
The OSHA fact sheet explains how workers may be exposed, what kinds of engineering controls and personal protective equipment they need, and how to use these controls and equipment properly. In addition, a new OSHA Quick Card alerts employers and workers to the hazards of mercury and provides information on how to properly clean up accidentally broken fluorescent bulbs to minimize workers’ exposures to mercury.
Fluorescent bulbs can release mercury and may expose workers when they are broken accidentally or crushed as part of the routine disposal or recycling process. Depending on the duration and level of exposure, mercury can cause nervous system disorders such as tremors, kidney problems, and damage to unborn children.
Under the Occupational Safety and Health Act of 1970, employers are responsible for providing safe and healthful workplaces for their employees. OSHA’s role is to ensure these conditions for America’s working men and women by setting and enforcing standards, and providing training, education and assistance.

Consumers and companies alike are becoming “confused” and “overwhelmed” by eco-labeling, according to a survey of more than 1,000 international companies including Hewlett-Packard, Nestlé, Canon, Sara Lee and E.On.
The joint study by the International Institute for Management Development and the Ecole Polytechnique de Lausanne concludes that eco-labeling has nearly reached the saturation point with companies and consumers increasingly concerned about the practice’s over-proliferation and credibility.

Are heatwaves more common than they used to be? That is the question addressed by James Hansen and his colleagues in a paper just published in the Proceedings of the National Academy of Sciences. Their conclusion is that they are—and the data they draw on do not even include the current scorcher that is drying up much of North America and threatening its harvest. The team’s method of presentation, however, has caused a stir among those who feel that scientific papers should be dispassionate in their delivery of the evidence. For the paper, interesting though the evidence it delivers is, is far from dispassionate.

Abstract: “Climate dice,” describing the chance of unusually warm or cool seasons, have become more and more “loaded” in the past 30 y, coincident with rapid global warming. The distribution of seasonal mean temperature anomalies has shifted toward higher temperatures and the range of anomalies has increased. An important change is the emergence of a category of summertime extremely hot outliers, more than three standard deviations (3σ) warmer than the climatology of the 1951–1980 base period. This hot extreme, which covered much less than 1% of Earth’s surface during the base period, now typically covers about 10% of the land area. It follows that we can state, with a high degree of confidence, that extreme anomalies such as those in Texas and Oklahoma in 2011 and Moscow in 2010 were a consequence of global warming because their likelihood in the absence of global warming was exceedingly small. We discuss practical implications of this substantial, growing, climate change.
