The hirer of an independent contractor may, despite the Privette doctrine, be liable for injuries suffered by the contractor’s employees if the hirer furnishes faulty equipment and asks or requires the contractor or its employees to use that equipment.  But not so if the hirer merely allows the contractor or its employees to use the faulty equipment.  In the latter situation, the hirer doesn’t retain control over safety or performance of the work, and it is up to the contractor to inspect the equipment and take appropriate safety measures–such as locking a scaffold’s wheels in this case.  The plaintiff also failed to raise a triable issue as to the concealed danger exception to Privette.  The contractor could have detected the danger of unlocked scaffold wheels even if the room was dark, as plaintiff asserted.
