Medical-Surgical/WAGD combination legend can be abbreviated to read "Med-Surg/WAGD"
What color should the new Medical-Surgical/WAGD Combination Legend be?
One half of the legend should read "Medical-Surgical” or the abbreviated "Med-Surg" and be white with black text, while the other half should read WAGD and be purple with white text. See image the below image for an example of both a Med-Surg/WAGD label and Medical Gas Valve Tag.
