Blood alcohol content BAC also called blood alcohol concentration or blood alcohol level is a measurement of alcohol intoxication used for legal or medical purposes. For example a BAC of 010 010 or one tenth of one percent means that there is 010 g of alcohol for every 100 ml of blood which is the same as 217 mmoll.

200 proof ethanol is commonly referred to as anhydrous Koptecs water specification is less than 01. Tax-paid ethanol prices include the federal excise tax on pure ethanol. To purchase tax-free ethanol customers must possess an Industrial Alcohol User Permit.
Human volunteers with some work experience in industrial environments reported that odor levels of 125 ppm were noticeable and that the intolerable odor level was higher then 255 ppm. Thus the warning properties should not be relied up on to prevent prolonged daily exposures to a concentration of vapors that could cause adverse affects. Safe use of protective clothing and equipment requires specific skills from training and experience.
Select this level when workers need the greatest level of skin respiratory and eye protection. This is the maximum protection for workers in danger of exposure to unknown chemical hazards or levels above the IDLH or.
