Agree ,Old space heaters or new ones that have lost their ability to shut off when tipped over ,Ive got one that needs to be fixed or thrown away and wont use it .My guess is alot of unfixed ones get sold to unexpecting buyers who never check them out.Its like lighting a continious match in an open room of flammable material.Mostly smaller homes without central air and heat are the fire prone buildings.People leave them on in the coldest days of the winter to try to keep up with the rooms temp and onced heated dont want to shut them off ,this combined with being at floor level ,dont get checked on , covers and clothes get put around,all the hazards are their to continue the threat of fire.I think one safety tool would be a cage of wire as a basket surround should be given with the purchase of these heaters ,save lives and property.
