(McKown v. Wal-Mart Stores Inc. (2002) 27 Cal.4th 219 did not create a separate exception to Privette v. Superior Court (1993) 5 Cal.4th 689 immunity for cases in which the hirer supplies unsafe equipment for use by a contractor or subcontractor. Instead McKown is a particular application of the Hooker v. Dept. of Transportation (2002) 27 Cal.4th 198 exception for cases in which the hirer retains and exercises control over safety of the work done in a manner that affirmatively contributes to the worker’s injuries. Passively allowing unsafe conditions to occur is not enough to impose liability on the hirer; instead, it must be shown that the hirer directed that the contractor perform its work in a certain way or interfered with the means and methods by which the work was to be accomplished. Here, summary judgment was properly granted to the hirer which merely allowed (but did not require) the contractor to use a ladder and scaffold on the site which was erected for use by the hirer’s workers, not the contractor.)
