The cake pan I used in the lab to carry vol flasks and sampl

Hi

I am in a difficult situation about discarding this 8"x8" cake pan that I used in Chemistry lab to carry glassware, w/ or w/o chemicals and also sample vials. I didn't have time to wash it in the lab with the detergent there. I have washed it at home. If it is not safe, I don't want someone to pick it up and use it. if it is safe, I could still use it In toaster oven (not for making cake) even though there are some scratches inside bottom.

I can provide the chemical used but know that all chemicals used were either soluble in methanol or water. We did use hexane to do extraction during derivatization of fatty acid methyl ester. We basically rinsed the glassware with methanol to reuse them when there is no time to let them them. The glassware with hexane were washed but I did carry the vol flasks containing fatty acid methyl esters dissolved in hexane in this cake pan.

Is it safe to use it after washing with hand dish washing detergent?

My personal practice: if it is used in the lab, it does not get used later to hold anything for human consumption. Overly cautious? Perhaps. But it prevents accidental exposure to some other nasty chemical that someone else has had in the lab.

The flip side to it is if it has only held things that you have held in your own ungloved hands, then it should be no worse that contact with your own ungloved hand. This may be true - but then again, you may be dealing with something where risk is the result of cumulative exposure.

There was a time when you could tell which GC I was using, because my coffee mug was likely to be sitting on top of the instrument. But I was younger and immortal then. These days I work in lab where we look in urine and find all kinds of things that we rub on the outside of our bodies - that suff we all (or many of us) assumed just stayed on the skin until we washed it off with soap and water.

An 8 by 8 pan is good for catching the drips while removing the P trap on your bathroom sink.

I once read a story about a man who worked as a gardener for a large country house. He had his own kettle and teapot for making tea in his large shed. One night someone broke into the shed looking for things to take. The thief could find nothing of value so out of spite he defecated into the gardeners teapot. The gardener was outraged and after emptying the contents onto the compost heap (nothing wasted) he cleaned out the teapot. He washed it out with water, followed by bleach and then boiled it through with water five times. He finaly sat down to drink tea made in the pot. He just couldn't bring himself to drink it, so he threw the teapot under a hedge where robins made a nest in it.

To cut a long story short...Throw it away!
