Aseptic technique

Working practices that prevent micro-organisms from contaminating sterile materials. Examples include slow, deliberate movements in Grade A, never blocking first air over open containers, keeping hands below and away from critical sites, sanitising gloves frequently with sterile alcohol, using sterile tools rather than hands, and keeping the number of items in the workspace to a minimum. Aseptic technique is assessed during operator qualification and observed by inspectors on the shop floor.
