What is the first step in preventing contamination during sterile preparation?

The first step in preventing contamination during sterile preparation is ensuring proper hand hygiene. Hand hygiene is critical because it eliminates transient microorganisms that may be present on the hands, which can easily transfer to sterile products or surfaces during the compounding process. By thoroughly washing and sanitizing hands before beginning any preparation, a technician significantly reduces the risk of introducing harmful pathogens into the sterile environment.

Effective hand washing techniques involve using soap and water or, in some cases, alcohol-based hand rubs, and should be performed before donning gloves and after using the restroom, before eating, or anytime hands may become contaminated. This foundational practice is essential for maintaining a sterile environment, as even the cleanest surfaces and equipment cannot compensate for the presence of bacteria or viruses that may be transferred from unclean hands.
