Special Precautions: Wear full protective gear including self-contained breathing apparatus, withdraw from fire area if conditions deteriorate
Advice for Firefighters: Use water spray to cool containers near fire, prevent runoff from entering water bodies or drains
Explosion Data: Not known to form explosive dust-air mixtures under normal conditions, monitor for pressurized container rupture
Personal Precautions: Wear chemical resistant gloves, goggles, lab coat, and, if necessary, a respirator to prevent inhalation
Environmental Precautions: Prevent chemical entry into drains, surface water, or soil; notify responsible authorities if environmental contamination is expected
