👉 Annex fumes refer to noxious, often toxic gases released from industrial processes or chemical reactions within facilities that house such operations. These fumes can contain a variety of harmful substances, including volatile organic compounds (VOCs), sulfur dioxide, nitrogen oxides, and heavy metals, depending on the specific activities taking place. Exposure to annex fumes can lead to serious health issues, ranging from respiratory problems and irritation of the eyes and skin to more severe conditions like organ damage or even death, particularly in enclosed or poorly ventilated areas. Proper monitoring and safety measures are essential to mitigate these risks and protect workers and nearby communities.
