My bad, as I hadn't gotten around to this... Please keep this in the
flammables storage cabinet. I believe that most all the personal
chemicals stored there in the bin are group L. Since this is a group D

bottle? This could be a slightly larger plastic box or beaker. Please
label the group on this container.
