Cheshire is considering banning outdoor wood furnaces. If it does, it will become the 10th state town to do so. Each outdoor wood furnace emits smoke equivalent to 22 indoor wood stoves, and they emit it 24 hours a day, seven days a week. The smoke plume can travel up to a half-mile, causing neighboring houses to fill with smoke and cause illness among neighboring families. Because of their basic design, it is possible that the furnaces can never be made safe. Their emissions problems are complicated because they cycle between oxygen-deficient and oxygen-rich burning. The smoke that leaves the stack, no matter the height, lacks the heat necessary to rise or be diffused. The smoke falls to the ground.

This final rule announces updated requirements that the National Institute for Occupational Safety and Health (NIOSH or Agency), located within the Centers for Disease Control and Prevention (CDC) in the Department of Health and Human Services (HHS or Department), will employ to test and approve closed-circuit respirators used for escaping atmospheres considered to be immediately dangerous to life and health, including such respirators required by the Mine Safety and Health Administration (MSHA) for use in underground coal mines. NIOSH and MSHA jointly review and approve this type of respirator used for mine emergencies under regulations concerning approval of respiratory protective devices. NIOSH also approves these respirators for use in other work environments where escape equipment ...

SANTA CLARA, Calif., Aug. 24, 2011 /PRNewswire/ -- Picarro, the world's leading provider of instruments for carbon and water cycle measurements, announced today the L2130-i, a new water isotope analyzer that advances measurement precision to a new level enabling scientists unprecedented capability to measure fine scale changes in the global water cycle or extractions from a milligram of tissue. With typical instrument precision of 11 per meg for oxygen and 38 per meg for hydrogen in water, the performance is up to an order of magnitude better than that typically produced by isotope ratio mass spectrometers. Low isotope concentrations have historically been expressed as 'per mil' , which is the ratio between two samples multiplied by a factor 1000. A 'per meg' is 1000 times more precise ...
