在無菌技術中，無菌區域的邊緣（通常為外圍 1 英寸或 2.5 公分）被視為已污染，因為邊緣可能接觸到非無菌區域或被觸碰。其他選項均違反原則：跨越無菌區、將無菌物置於腰部以下、背對無菌區，皆會導致無菌視野失效。
In sterile technique, the outer 1 to 2 inches of a sterile field are considered contaminated because they may come into contact with non-sterile surfaces. Maintaining awareness of this boundary prevents inadvertent contamination of sterile instruments and supplies.
