Handling Precautions
Avoid dust formation and inhalation of vapors, mist, or gas. Prevent contact with skin and eyes. Use personal protective equipment (PPE), including gloves and protective eyewear. Ensure adequate ventilation in the workspace. Keep away from sources of ignition, as the product can form explosive dust/air mixtures.
Firefighting Measures
Use dry chemical, carbon dioxide, alcohol-resistant foam, or water fog to extinguish fires. Wear self-contained breathing apparatus and chemical-protective clothing during firefighting. Be aware of the potential for explosive dust/air mixtures.
Environmental Precautions
Prevent further spillage if safe to do so. Do not allow the chemical to enter drains or waterways. Dispose of in accordance with local environmental regulations.
Hazard Classification
According to ECHA, this substance is classified as harmful to aquatic life with long-lasting effects.
