Discontinued Operations and Disposal Groups [Abstract]
Discontinued Operations	DISCONTINUED OPERATIONSOn July 2, 2016, the Company completed the separation of its former Test & Measurement segment, Industrial Technologies segment (excluding the product identification businesses) and retail/commercial petroleum business by distributing to Danaher stockholders on a pro rata basis all of the issued and outstanding common stock of Fortive Corporation (“Fortive”), the entity the Company incorporated to hold such businesses. For the nine-month period ended October 1, 2021, the Company recorded an income tax benefit of $86 million related to the release of previously provided reserves associated with uncertain tax positions on certain of the Company’s tax returns which were jointly filed with Fortive entities. These reserves were released due to the expiration of statutes of limitations for those returns. This income tax benefit is included in earnings from discontinued operations, net of income taxes in the accompanying Consolidated Condensed Statements of Earnings.
