2) A student asked me if there were any chemicals for which you would NOT want to use water in case of chemical exposure. I did a quick search and the Canadian CCOHS (their OSHA) advises "...Note that the manufacturer/supplier .. may recommend an alternative agent in exceptional cases if water is clearly inappropriate." I have read plenty of SDS's in my time but have never seen an SDS state anything other than using water as the first step. Has anyone ever encountered any other initial instructions for dermal or eye exposure? (Of course there may be additional steps AFTER water flushing, like use of calcium gluconate gel, etc)...

From Toxnet; also discussed in "Prudent Practices":

0.4.5 DERMAL EXPOSURE
    A)  OVERVIEW
     1)  Remove phenol with undiluted polyethylene glycol 300 to
         400 or isopropyl alcohol prior to washing, if readily
         available. Wash exposed areas twice or for at least 10
         minutes with large quantities of SOAPY water. Water
         alone may be harmful. A physician may need to examine
         the exposed area if irritation or pain persist after
         the area is washed.

So...two questions for Friday...

1) If you found a large stack of lead sheets...sitting in a storage area for some time (who knows how long!?)...would you be concerned about lead dust in the immediate area, say the surrounding floor? I understand that grinding, sanding, filing, etc creates lead dust but this situation doesn't fit any of those...I cannot find any references so in case I'm imagining that just because it's soft, dust forms over time....I wanted to check...

MANY THANKS and happy Friday to all!
