[DIYbio] Re: Hacking Stink Bugs

Gents,

 

Thanks again for the great leads and advice.  BUGSS looks like an awesome space.  Too bad you have to be 18 to participate.  My daughter is just 12.  And this one is for her.  Still, we'll contact them as in community.

 

As to chloroform I have some numbers for consideration.  What volume of chloroform exceeds exposure limits when left to completely evaporate in a sealed 8x8x10 room?

 

(A)  The absolute max permissible exposure limit according to OSHA is 240mg /m3.  So that would require 3.3mL.

 

(B)  The recommended threshold limit value according to ACGIH is 50mg /m3 in an 8 hour workday and 40 hours per week..  Here 0.78mL are required.

 

(C)  Finally NIOSH has established 10mg /m3 as a recommended exposure limit over 1 hour.  Just 0.148mL are required.

 

Good stuff yes.  But it's use clearly demands caution, a chemical fume hood and proper disposal.  So we'll be reading Mr. McCorkle's paper with interest.
