Is it safe to put dry ice in front of fan?

A: The direct way that you’re probably considering might be to simply leave the dry ice in a room, maybe with a fan blowing over it to circulate the cold gas. That’s a bad idea because as the dry ice (frozen CO2) evaporates, the CO2 gas concentration in the room will go up.

What happens when you put dry ice in a fan?

Turn the fan on so that the air blows over the top of the bowl of dry ice. The dry ice will transition or sublimate into very cold carbon dioxide gas. The gas will absorb the heat from the warm air pushed out of the fan. The cool air will then circulate around the room. Related Articles.
