Prep, Packaging & StorageQuestion 79 of 100

A technician notices that a hinged instrument is stiff during inspection and asks which lubricant to apply before packaging. What is correct?

a.A petroleum-based penetrating oil applied to hinges
b.Silicone spray intended for industrial equipment
c.A water-soluble, steam-penetrable instrument lubricant applied per manufacturer instructions
d.No lubricant should ever be applied to instruments

Explanation

Instrument lubricant, sometimes called instrument milk, is water soluble so steam can penetrate it and reach the metal surface, and it protects hinges and box locks from stiffness and corrosion. Petroleum-based oils and industrial sprays form a barrier that blocks sterilant contact and can leave toxic residues. Lubrication is a normal step for hinged instruments when the manufacturer directs it.
