What industries are most at risk of plastic fume exposure?

Plastic fume exposure is most common in industries where plastics are heated, moulded, or machined. This includes plastic manufacturing, recycling, injection moulding, 3D printing, and fabrication workshops. Workers in automotive, electronics, and packaging sectors may also be at risk - especially where PVC, nylon, polystyrene, or acrylics are used. Even short-term exposure can irritate the lungs, so it's not just about long hours - it's about the type of plastic and process used.
