👉 Nickel fumes are fine, toxic particles released when nickel-containing materials, such as alloys, batteries, or industrial metals, undergo high-temperature processes like welding, smelting, or corrosion. These particles are primarily composed of nickel oxides and other metallic compounds, which can become airborne and pose significant health risks upon inhalation. Exposure to nickel fumes can lead to respiratory issues, including irritation of the lungs and airways, as well as more severe conditions like nickel allergy or asthma. In occupational settings, prolonged exposure to these fumes can result in chronic health problems, making it crucial to implement proper ventilation and protective measures to safeguard workers' health.
