Koh, In my opinion, this is a totally unacceptable situation. Label or not, some of the units sold will eventually encounter a situation where the ventilation hole gets blocked. Since the design is nearly complete, your choices will be limited. I think that you must include an overtemperature shutdown device such as a bimetal, thermal fuse, or PTC thermistor. All coffemakers, portable hair dryers, and similar devices include them. If you do not, you run the risk of major lawsuits, especially in the U.S. market. If a child becomes injured the financial penalties could be massive.

Due to the current drawn is high and heat are dissipated. Therefore the encloseure need some ventilation hole. Unfortunately, till the very late stage of the design cycle, they found out if this ventilation hole was blocked, it will cause the plastic enclosure to melt. A question was asked, Is there a safety label/logo that we can affixed onto the plastic enclosure so that to tell user not to block this enclosure? (Or not to place it in a area where the ventilation will be blocked.) I've never seen such label or logo before. Has anyone out there seen such type of label/logo? Any advice from the group would be much appreciated.
