Two technicians deicing a plane at Milwaukee General Mitchell International Airport in winter. They are applying Type I aircraft deicer (which is orange) to the plane. Type I deicer is typically applied hot (hence the steam) and it is used to remove existing ice and snow. This will then usually be followed with Type IV (which is green) to prevent new ice.
