What do you mean? Can you give me more details?

I mean, can they be a fire hazard?
user
I don’t know about that.  Can you tell me more about the situation? Are you using the heater on a fireplace?  Do you have any other heater in the room?  What materials are in the room?  Do you feel any heat from the heater?  How are you touching the heater?
