Actually, Russ, you need to watch the video again.  At 0:53 the post-doc uses phenol as a solution with which one can only wear safety glasses.  The grad student does later specify goggles as she is placing a bottle of crystalline phenol in the hood.

Actually, Kay, you need to watch the video again. At 1:28 in the video, they specifically say you should wear safety goggles when you work with Phenol. While you are right that much of the focus seems to be on safety glasses, the “disclaimer” in the beginning specifically indicates those are only for use with small quantities of lower hazard reagents where there is no splash hazard.

I’m sorry but I must disagree with all the praise for this video.  Yes, there are parts that are very good, but at the beginning the post-doc mentions phenol solution as one with which it is ok to just wear safety glasses.  No mention of the concentration of solution.  I know that phenol is an active ingredient in some throat sprays, but there the concentration is very low.  In lab the concentration can certainly be high enough to cause damage to the eye.   I was also disturbed by the fact that most of the glasses were open across the forehead.  There was no shielding.  In those cases where safety glasses are deemed sufficient I require said glasses to have a barrier on top.

P. S. I did like the dissolving head.  That was cool.

 

 

 

 

Awesomely done!  Another winner from Haim and you and the talented gang at UCSD!

 

Thanks so much for sharing.

Dear all,

 

I hope you are having a great week.

 

Here is an excellent PPE video that was produced by Professor Haim Weizman:  https://www.youtube.com/watch?v=RXmG8mjUviI

 

Be safe out there,
