🚨

CARCINOGEN WARNING

Ethylene Oxide is a proven human carcinogen causing cancer, birth defects, and genetic damage. EPA studies show elevated cancer risks near ETO facilities—immediate detection at sub-ppb levels is critical for worker and community protection.

  • OSHA Standard: 1 ppm 8-hour TWA, 5 ppm 15-minute STEL
  • Group 1 Carcinogen: Sufficient evidence in humans (IARC)
  • Reproductive Toxin: Causes birth defects and miscarriages
  • No Safe Threshold: EPA cancer risk at 0.02 ppb

The ETO Health Crisis

Ethylene oxide's proven cancer-causing properties and ubiquitous healthcare use create an urgent need for ultra-sensitive detection.

Cancer-Causing Sterilant Gas

Ethylene oxide is extensively used to sterilize medical devices and equipment that cannot withstand high-temperature sterilization. However, this life-saving application comes with serious health risks that have made ETO one of the most regulated industrial chemicals.

Recent EPA studies have identified communities near ETO facilities with elevated cancer risks, leading to increased regulatory scrutiny and the urgent need for precise, continuous monitoring to protect both workers and surrounding populations.

Critical Health Impacts

  • Group 1 Carcinogen: Proven human carcinogen (IARC)
  • No Safe Threshold: EPA cancer risk at 0.02 ppb
  • Reproductive Toxin: Birth defects and genetic damage
  • Community Risk: Elevated cancer rates near facilities
  • Worker Exposure: Healthcare and industrial workers at risk
