Hi, Thanks for posting in HCM. I am sorry to hear of your mishap. There is no cause for alarm, and that you have taken care of most issues. When polypropylene (plastic) melts, depending on the particular material, it may release plasticizers, stabilizers, and biocides. Most of these materials will have a very low vapor pressure, and hence will probably form aerosols. They can form a large number of organic compounds (oxidation and/or decomposition products). These will include some formaldehyde, an eye and respiratory irritant, as well as related compounds. If they are inhaled for a short duration, it would not affect in the long run. Hope the information provided is clear.
