Introduction
Ethylene oxide (EtO) is a versatile chemical that is widely used for sterilising medical equipment, manufacturing antifreeze, and producing other chemicals. However, prolonged exposure to this colourless, flammable gas in the workplace has raised significant health concerns, particularly its potential to cause cancer. In this blog, we will therefore explore whether ethylene oxide can cause cancer in a workplace setting, as well as how exposure happens and practical safety measures to mitigate risks.
What is Ethylene Oxide?
Ethylene oxide is a highly reactive compound that plays an important role in various industries. Most notably, it is recognised for its use as a sterilising agent for medical devices and laboratory equipment. However, despite its effectiveness, the safety risks associated with EtO cannot be overlooked.
Common Uses of Ethylene Oxide in the Workplace
- Sterilisation of medical equipment
- Production of ethylene glycol (antifreeze)
- Manufacturing of detergents and plastics
- As a fumigant in certain agricultural processes
Can Ethylene Oxide Cause Cancer?
The short answer is yes, ethylene oxide has been shown to pose a significant cancer risk. In fact, the International Agency for Research on Cancer (IARC) classifies ethylene oxide as a Group 1 carcinogen, which means that there is sufficient evidence to confirm its carcinogenicity in humans. This classification highlights the importance of strict safety measures and exposure control in workplaces where ethylene oxide is used.
Types of Cancer Linked to Ethylene Oxide
Several types of cancer have been linked to ethylene oxide exposure. One of the strongest associations is with leukaemia, a blood cancer that has been closely connected to prolonged contact with this chemical.
Additionally, non-Hodgkin lymphoma, which affects the lymphatic system, has also been linked to ethylene oxide exposure over time.
Breast cancer is another concern, particularly for women who have been exposed to this substance for extended periods. These connections highlight the serious health risks associated with ethylene oxide and the importance of minimising exposure whenever possible.
Detecting Ethylene Oxide
You can detect ethylene oxide with the MSA Ultra X5000.
The MSA ULTIMA X5000 Fixed Gas Detector represents the future of gas detection for oxygen and toxic gases. Equipped with MSA XCell® gas sensors featuring TruCal® technology, it offers calibration cycles of up to 24 months. Additionally, its advanced, multi-lingual OLED display is easy to read, while the unique touch-screen interface ensures simple navigation.
