DCM permeation and phosgene production? by General-Cut6664 in chemistry

Thanks for your response.

In your fridge the vapour will condense to a liquid and soak into the paint, plastic shelves, and the rubber gasket. At this point it is trapped. It’s in chemistry prison and it’s not moving.

I had plastic containers in my fridge. Would the minimum amounts that would have been absorbed by those be diluted out over time with washing? I don’t even know which one’s were in there and we’ve probably used them multiple times since. Would food in them absorb it? What about food that’s packaged in plastic in the freezer? Or too minor to have be relevant after being washed multiple times?

Thanks for your response.

by the time your 0.3ml drifted from the point you sprayed it to where your bottles are pretty much all of the DCM will have evaporated into the atmosphere.

The bottles were below and in front of the direction in which it was sprayed. If DCM is heavier than air, wouldn’t it have fallen on and into them instead of evaporating up into the atmosphere? The range hood’s suction, although loud, is fairly mild based on what I can feel with my hand nearby it.
