Personal Protective Equipment (PPE) in Standard Precautions for Sterile Processing

The realm of healthcare is intrinsically associated with various risks, with infections being a primary concern. Sterile processing departments (SPD) in hospitals play a crucial role in ensuring the sterility and safety of surgical instruments and devices. Integral to this mission is the use of Personal Protective Equipment (PPE). Within the framework of Standard Precautions, PPE is paramount to protect both the staff and the sterile equipment. This article will explore the importance, types, and best practices associated with PPE in sterile processing.

The Rationale Behind PPE in Sterile Processing

Sterile processing departments are ground zero for the battle against (HAI). The instruments and devices that pass through these departments come into direct contact with patients’ internal tissues, making the margin for error negligible. The role of PPE here is twofold:

  • Protection for Workers: Sterile processing staff are exposed to contaminated instruments that carry blood, tissue remnants, and other potentially infectious materials. PPE serves as a barrier, protecting them from this exposure.
  • Protection for Instruments: Workers can be carriers of infectious agents. PPE ensures that these agents don’t get transferred to the sterilized instruments, thus maintaining their sterility.

Key PPE Components in Sterile Processing


Gloves offer direct protection against contact with contaminated instruments and chemicals. They should be durable, especially when handling sharp instruments, and should resist puncture. It’s essential to ensure gloves are of the right fit, as those too tight might constrict, while loose ones can impair dexterity.


Fluid-resistant gowns or aprons protect the worker’s clothing and skin from splashes of contaminated fluids or chemicals. These should be appropriately sized and should cover the individual’s front and arms.

Face Shields and Masks

These protect the face, mouth, nose, and eyes from splashes or sprays of potentially infectious materials. Masks additionally serve to prevent the wearer from contaminating sterile equipment through respiratory droplets.


Goggles offer eye protection, especially when chemicals are in use, ensuring that no splashes harm the eyes.

Shoe Covers

In environments where the floor might get contaminated, shoe covers act as a barrier, preventing the spread of contaminants outside the SPD.

Best Practices for Using PPE in Sterile Processing

Understanding the Right Equipment for the Task

Not all tasks in the SPD demand the same level of protection. For instance, while inspecting an instrument might require gloves, decontaminating it might necessitate the full ensemble of PPE. Staff should be trained to assess and employ the right level of protection for each task.

Donning and Doffing

The process of putting on (donning) and taking off (doffing) PPE is as vital as wearing it. Incorrect methods can lead to contamination. It’s crucial to follow a systematic approach: typically, the PPE that got contaminated first gets removed first.

Regular Inspection and Replacement

PPE is not invincible. Gloves can get punctured, gowns can tear, and masks can lose their integrity. Regular inspection ensures that compromised PPE is identified and replaced promptly.

Education and Training

Continuous education and training sessions can reinforce the importance of PPE and keep the staff updated on any changes or advancements in PPE protocols.

Challenges and Considerations

Despite its clear advantages, the implementation of PPE isn’t without challenges. There are concerns related to comfort, especially when worn for extended periods, which can sometimes lead to non-compliance. The availability and cost of quality PPE can also be a constraint, especially in low-resource settings. Addressing these challenges requires a combination of administrative commitment, staff involvement, and innovative solutions.


In the high-stakes environment of sterile processing, the role of Personal Protective Equipment is undeniable. It stands as a robust defense against the spread of infections, safeguarding both the staff and the patients. As healthcare continues to evolve, the principles of safety and prevention remain constant, with PPE at the forefront of this ever-important mission.
