👉 Ec fumes, or ethylene oxide emissions, are volatile organic compounds released when ethylene oxide (EtO) is used as a sterilant in medical equipment and other applications. These fumes can be harmful to human health, causing respiratory irritation, eye and skin damage, and potentially leading to more severe effects like cancer with prolonged exposure. Ethylene oxide is highly flammable and has a strong odor, but it is also toxic and carcinogenic. Proper ventilation and safety protocols are essential to minimize exposure in environments where EtO is used.
