Andersen Sterilizers’ Response to Proposed EPA Guidelines to Reduce EO Emissions
On April 13, the U.S. Environmental Protection Agency (EPA) published a risk assessment of ethylene oxide (EO or EtO) and proposed regulatory requirements which, if approved as written, would severely restrict the use of EO sterilization in all facilities.
The comment period is set to expire on June 27.
As you know, Andersen sterilizers use EO as sterilant. We wanted to reach out to our customers proactively to let you know our position, explain how this may impact you and ask for your help.
Please note: These are proposed regulations. A final decision on these proposals is expected March 2024, after-which, there will be a 18-month phase-in period for whichever of these proposals make it into law.
Proposals that may affect you
- Under the proposed EPA regulations, health care facilities (HCF) – including veterinarians and single practitioners like dentists and plastic surgeons – would no longer be exempt from burdensome EPA EO regulations.
- The document proposes several engineering changes to HCF buildings, such as a dedicated room for sterilization with negative pressure air-flow and abatement equipment. (p. 54)
- While the document is ambiguously worded, it seems clear the EPA intends to limit HCF workplace exposure levels to 10 ppb (p.12, 79). This level is so low, it is less than the exposure many individuals have in the natural world, from plant decay and made inside their own body for example, and would be unrealistic for businesses to comply with.
- The regulations ask about the feasibility of requiring HCF employees who operate sterilization equipment to wear “Self Contained Breathing Apparatus (SCBA) or supplied airline respirators” (p. 55) to reduce their exposure risk. The question implies an intention to require this PPE of HCF staff.

Not written for you
The proposed regulations are written to regulate a different industry — commercial sterilization facilities that have chambers large enough to drive a forklift into. These facilities can emit thousands of pounds of EO into the surrounding environment per year (in some instances, over three tons).
However, in drafting these new rules, the EPA does not differentiate between a commercial sterilization facility and the sterilizers we create — and you operate — that use just a small amount of EO per cycle, 17.6 grams or less. This is 90% less than any other “all in one” (p. 18) sterilizer on the market and thousands of pounds less than the commercial sterilization facilities.
As you may know, EO has been thoroughly evaluated and re-evaluated by scientists and regulatory bodies worldwide for over 70 years and was first approved for use by the U.S. government in 1950, and by the EPA in 1971 ― shortly after the agency was formed. In making its recommendations, the EPA disregarded this and other scientific and peer-reviewed data, including an assessment from the Texas Commission on Environmental Quality (TCEQ).
Andersen Sterilizers has actively joined the efforts of Ethylene Oxide Sterilization Association (EOSA), the Advanced Medical Technology Association (AdvaMed) and several other industry organizations in encouraging the EPA to consider all available and relevant peer-reviewed data as they make vital decisions to protect public health and worker safety ― while not disrupting medical device availability and negatively impacting patient care and safety.
We believe imposing draconian regulations on the health care providers, veterinarians and research facilities that use our sterilizers would needlessly negatively impact businesses like yours as well as the health and safety of patients.
Draft regulations like this often undergo a great deal of change before being enacted, and occasionally never go on the books at all. We feel that there is a good chance that the final version of these regulations will not apply to Andersen’s customers.
Regardless, we will keep you updated via these pages and social media.
