👉 Core fumes refer to the primary, often toxic vapors released by a substance during its vaporization or decomposition. These fumes typically contain a complex mixture of chemicals, including volatile organic compounds (VOCs), heavy metals, and other hazardous substances, depending on the material. Common core fumes can include carbon monoxide, formaldehyde, benzene, and various particulates, which pose significant health risks if inhaled over long periods. The composition of these fumes can vary widely based on factors like temperature, pressure, and the specific chemical properties of the substance. Understanding and controlling core fumes is crucial in industrial settings to protect worker health and comply with environmental regulations.
