Here is a very different question for the group.


One of our UF researchers at NASA is using dry samples of perchlorates under UV lights to simulate the perchlorates found in Mars soils by the remote sampling devices on the rovers. 


He is concerned about flammability or explosions of the pure reagent grade perchlorate compounds.  The “soils” mixture in the growth chamber will simulate the Mars atmosphere.  It will be under UV irradiation at temperatures between -80 to +20 oC.  The growth chamber is kept at a low pressure (7 mbar) versus Earth sea level pressure (1015 mbar), and it  will be under a nearly pure CO2 atmosphere. 


Any thoughts on if the low pressure and low oxygen atmosphere render the experiments safe?  Any other thoughts?


As always- a grateful thank you any replies.
