What items should never be placed in the dryer due to fire or explosion risk?

Do not dry articles that have been cleaned in, washed in, soaked in, or spotted with gasoline, dry-cleaning solvents, or other flammable or explosive substances. Do not dry items contaminated with cooking oils, as these may cause a chemical reaction that could cause a load to catch fire. Items containing foam rubber or similarly textured rubber-like materials should not be dried using heat. (Page 6)
