Reference Manual on Scientific Evidence: Third Edition This s o r t a says it all These limits generally are based on assessments of health risk and calculations of concentrations that are associated with what the regulators believe to be negligibly small risks. The calculations are made after first identifying the total dose of a chemical that is safe (poses a negligible risk) and then determining the concentration of that chemical in the medium of concern that should not be exceeded if exposed individuals (typically those at the high end of media contact) are not to incur a dose greater than the safe one. So OSHA standards are what is the guideline for what is acceptable ''SAFE LEVELS'' OSHA SAFE LEVELS All this is in a small sealed room 9x20 and must occur in ONE HOUR. For B e n z o [a]p y r e n e, 222,000 cigarettes. "For Acetone, 118,000 cigarettes. "Toluene would require 50,000 packs of simultaneously smoldering cigarettes. Acetaldehyde or Hydrazine, more than 14,000 smokers would need to light up. "For Hydroquinone, "only" 1250 cigarettes. For arsenic 2 million 500,000 smokers at one time. The same number of cigarettes required for the other so called chemicals in s h s / e t s will have the same outcomes. So, OSHA finally makes a statement on s h s / e t s : Field studies of environmental tobacco smoke indicate that under normal conditions, the components in tobacco smoke are diluted below existing Permissible Exposure Levels (PELS.) as referenced in the Air Contaminant Standard (29 CFR 1910.1000)...It would be very rare to find a workplace with so much smoking that any individual PEL would be exceeded." -Letter From Greg Watchman, Acting S e c y, OSHA. Why are their any smoking bans at all they have absolutely no validity to the courts or to science! This pretty well destroys the Myth of second hand smoke: Lungs from pack-a-day smokers safe for transplant, study finds. Using lung transplants from heavy smokers may sound like a cruel joke, but a new study finds that organs taken from people who puffed a pack a day for more than 20 years are likely safe. What's more, the analysis of lung transplant data from the U.S. between 2005 and 2011 confirms what transplant experts say they already know: For some patients on a crowded organ waiting list, lungs from smokers are better than none. "I think people are grateful just to have a shot at getting lungs," said D r S h a r v e n Ta g h a v a cardiovascular surgical resident at Temple University Hospital in Philadelphia, who led the new study........................... I've done the math here and this is how it works out with second hand smoke and people inhaling it! The 16 cities study conducted by the U.S. DEPT OF ENERGY and later by Oakridge National laboratories discovered: Cigarette smoke, bartenders annual exposure to smoke rises, at most, to the equivalent of 6 cigarettes/year. 146,000 CIGARETTES SMOKED IN 20 YEARS AT 1 PACK A DAY. A bartender would have to work in second hand smoke for 2433 years to get an equivalent dose. Then the average non-smoker in a ventilated restaurant for an hour would have to go back and forth each day for 119,000 years to get an equivalent 20 years of smoking a pack a day! Pretty well impossible !
