d. Create a sterile field using one of the two methods given below.
(1) Preferred method. The preferred method is to use a double-wrapped
sterile package. Do not let your hands pass over the sterile field or the wrapped sterile
object while you are establishing the field.
(a) Lay the package so that the flaps are on top (figure 3-1).
Figure 3-1. Flaps on top.
(b) Open the outer layer, usually a paper or plastic cover. This layer
forms a barrier between the work surface and the inner wrapper.
Open the inner wrapper.
1 Using one hand lift the distal flap up and away from the package
(figure 3-2). Let this flap drop gently.
