Storing chemicals on the floor is not acceptable, period and probably 
violates fire/NFPA codes.   Would you let someone store bottles of 
toluene on the floor?  Carbon tetrachloride?

We always stored our base baths on the lab bench next to the sink 
where the glassware is rinsed.  I have also seen people store the 
entire base bath in the sink, which goes against housekeeping 
principles, but is enormously practical and reduces spills, splashes 
and accidental eye/skin exposure.

I have never seen anyone use secondary containment in those scenarios 
and have never heard of an incident where it would have been needed. 
In contrast, a secondary tray is a must for acid baths, especially 
because they eat away at soapstone countertops.  Something along 
these lines:
