These indicators test the true effectiveness of a sterilization cycle by challenging it with highly resistant bacterial spores. But what happens when it's not the test BI that fails, but the control BI?
While a failed test BI raises red flags for a potential sterilization breach, a failed control BI introduces an entirely different set of concerns. This article breaks down what a control BI is, what its failure means, and the exact steps your office should take to investigate and correct the issue.
What is a Control BI?
A Control BI is a self-contained biological indicator that is not exposed to the sterilization process. Its job is to serve as a positive control to prove that the spores

One of the most advanced and trusted materials in the field is SMMS, short for Spunbond-Meltblown-Meltblown-Spunbond. This multi-layered nonwoven fabric plays a critical role in keeping sterilized instruments safe until use.
So, what exactly is SMMS, and why does it outperform traditional single-ply wraps?
SMMS: A Four-Layer Engineered Barrier
SMMS is a composite structure made of:
- Two outer spunbond layers
- Two inner meltblown layers
Each layer serves a distinct and essential purpose:
- Spunbond Layers (Outer

When used correctly, it creates a critical barrier that protects sterile instruments from contamination until point of use. But what happens when your SMMS wrap starts melting in the autoclave? It’s more than frustrating, it’s a red flag. This guide walks you through common causes and solutions when your sterilization wrap doesn’t perform as expected.
Understanding the Material: What Is SMMS Wrap?
SMMS (Spunbond-Meltblown-Meltblown-Spunbond) is a four-layer nonwoven material commonly used in sterilization wrap. It's engineered to resist microbial penetration and mechanical wear while allowing steam to pass through during sterilization. When SMMS wrap melts, the problem usually isn’t the wrap itself, it’s the processing conditions.
Troubleshooting: Where Things Go Wrong
Here’s a practical breakdown of what to investigate if your SMMS wrap is melting or distorti

"This is literally a human body part... how is this NOT biohazard waste?" You're not alone. One of the most misunderstood areas in dental Infection Prevention and Control (IPAC) is biomedical waste classification, especially when it comes to extracted teeth. Let's clear it up.
First: What Is Biomedical Waste?
According to the Centre for Disease Control and dental regulatory bodies, biomedical waste is classified as hazardous waste and must:
- Be stored in colour-coded containers with the universal biohazard symbol
- Be released to an approved biomedical waste carrier
However, that does NOT include all waste.
Biomedical waste falls into two categories:
1. Anatomical Waste (Human Tissue)
