Sterilization gas lingers in packaging materials and outgasses during shipping, delivery, storage, and use—posing invisible risks to medical

workers.

A growing body of government data now shows that workers exposed to ethylene oxide (ETO)-a common gas used to sterilize medical equipment-may face severe cancer risks under outdated federal safety limits. As a result, Air by CCSquared Inc. has launched a new, ultra-sensitive ETO airtest to help workers and employers understand their exposure and take Action. 

According to the U.S. Environmental Protection Agency (EPA), the exposure to 0.01 ppb for a lifetime causes no more than 1 cancer in approximately 10,000 people, or 100,000 times lower than the current OSHA limit of 1000 ppb, a value accepted for decades as a safe concentration in the workplace. EPA modeling shows that chronic exposure to ETO at OSHA’s legal limit could increase lifetime cancer risk to greater than 1 in 10—a level which public health experts call unacceptable. 

With the ability to detect ETO concentrations as low as 2 parts per billion (ppb), the test provides an unprecedented layer of protection for workers, especially those in high-risk environments such as sterilization facilities, medical clinics, warehouses, and homes near industrial operations.

Key features of the Air by CCSquared ETO test include:

● High Sensitivity to 2 ppb – Offers early detection at levels far below conventional badge style monitors, enabling faster protective actions.

● ISO 17025:2017 Accreditation – Ensures all results are scientifically defensible, reproducible, and trusted for regulatory and legal contexts.

● Field-Ready Sampling Kits – Simple, flexible kits are designed for use in workplaces, clinics, warehouses, or residential settings.

● Expert Interpretation Support – Helps individuals and organizations understand their results and plan appropriate next steps.

“This test isn’t just about compliance—it’s about access, transparency, and protection,” said Dr. William Chapman, founder and CEO of Air by

CCSquared. “People have the right to know what’s in their air they breathe and how it could affect their health. With this tool, we’re giving them real data they can finally act on.”

How Community Risk Research Uncovered this Workplace Crisis

The EPA initially modeled ETO risk to assess ambient air levels in communities near sterilization and chemical manufacturing facilities. But those models revealed something even larger: the real danger may lie inside these facilities and throughout the medical supply chain all the way to the

customer, where exposure is frequent, direct, and currently unmonitored at high sensitivity.

The EPA finding has sparked dozens of lawsuits from medical professionals, warehouse workers, sterilization technicians, and others in the medical device supply chain who suffer from cancer after long-term ETO exposure on the job. “EPA’s community health studies inadvertently exposed a workplace safety gap that had gone unaddressed for decades,” said Dr. Chapman. “Our new test is designed to help close that gap and protect workers' lives.”
