Ralph,

Since the highest I've seen go through our Chemical Stores is 30% I had to look at Fisher to see if 50% is even readily available (it is at ca $68/bottle). But, one also wonders if this is a mislabeled bottle (more likely 5.0%?).

As an example of mixed up labels, someone forwarded me nice labels they were making for their spray bottles (secondary containers). They dutifully listed the exact concentration from the primary containers (5% H2O2). The only problem is that the primary container was the concentrate, not Ready To Use (RTU). So the question was, are they putting the original concentrate in the sprayer, or are they putting the diluted solution, but writing the wrong concentration on the label? Or, were they just putting the decimal in the wrong place?

This showed up in today's headlines and seems like it might be immediately useful to DCHAS-L readers. I don't know if this is strictly a local error or more systemic, but having 50% H2O2 on the loose seems like something we should be aware of...

KFD warns of public distribution of 'dangerous' chemical this week

KNOXVILLE, Tennessee - The Knoxville Fire Department is warning about the inadvertent distribution of a dangerous chemical to the public that's not safe for households.

According to KFD, "multiple visitors" to the Fish Hospitality Pantry at 122 W. Scott Ave., in Northwest Knoxville picked up Tuesday one-gallon jugs of a hydrogen peroxide mix.

"The liquid mixture contains 50% hydrogen peroxide and is not intended for household or community use. The highly concentrated oxidizer poses a significant risk of first- and second-degree burns upon contact with skin," KFD said in a Wednesday release.

It appears 54 jugs went out and probably have ended up in the homes and vehicles of members of the public.
