👉 Casting fumes are a mixture of volatile organic compounds (VOCs) and particulate matter released during the casting process, particularly when molten metal is poured into molds. These fumes can include gases like benzene, toluene, and xylene, as well as fine particles that can irritate the respiratory system and cause health issues such as headaches, dizziness, and long-term damage to lung function. Proper ventilation and protective measures are essential to minimize exposure to these harmful substances in industrial settings.
