Question
MSDS interpretation and information identification. What is the lower concentration limit (vol%) at which a mixture ofethanol in air can explode? What is the average air concentration (ppm) you can be legally exposed to over an eight- hour period? · . Could ethanol vapor collect in low spots? . Your lab partner urges you not to shake the bottle of anhydrous ethanol in your hand for fear it might explode. What information can you use to calm his fear? What is another name for ethanol:? What in the MSDS says it would be safe on a cold snowy day to strike a match even if there could be ethanol vapors present? What is the concentration of ethanol in air, in volume %, inside a 5 gallon carboy ofpure ethanol at 20 °C? .Explanation / Answer
1) Lower concentration limit at which ethanol in air can explode is 3.3 % Vol
& upper concentration limit for the same is 19 % Vol
2) Prefered average air concentration with contaminants exposure permissible limit is < 1 PPM
3) There are chances of ethanol vapor collect in lower spot
Ethanol has a boiling point (ard 78 C)
4)Lower concentration limit at which ethanol in air can explode is 3.3 % Vol & upper concentration limit for the same is 19 % Vol. If it is not in this range explosion will never happen.
5)Ethyl alcohol
6)The flash point of pure ethanol is 16.60 °C (61.88 °F), less than average room temperature.Less than 16.60 °C is safe
