Safe handling requires appropriate personal protective equipment due to its Skin Sens. 1 classification. Wear protective gloves, safety goggles, and protective clothing to prevent skin contact. Ensure adequate ventilation when working with this compound. Avoid generating dust or aerosols. Wash hands thoroughly after handling and remove contaminated clothing immediately. Work in well-ventilated areas and consider using fume hoods for operations involving powder handling or weighing.

Store this compound in tightly sealed containers in a cool, dry, well-ventilated area away from incompatible materials. Keep containers closed when not in use and protect from moisture and heat. Due to its environmental hazard classification (Aquatic Acute 1, Aquatic Chronic 1), ensure secure storage to prevent environmental release. Store away from oxidizing agents and other reactive chemicals. Maintain proper labeling and inventory records according to chemical storage regulations.

In case of skin contact, immediately remove contaminated clothing and wash the affected area thoroughly with soap and water for at least 15 minutes due to its skin sensitization potential. For eye contact, flush immediately with clean water for 15 minutes. If inhaled, move to fresh air immediately. Seek medical attention if irritation persists or sensitization symptoms develop. Do not induce vomiting if accidentally ingested - seek immediate medical attention.

Disposal must comply with local, national, and international environmental regulations due to its Aquatic Acute 1 and Aquatic Chronic 1 classifications. Never discharge to sewers or waterways. Contact authorized hazardous waste disposal companies for proper treatment and disposal. Incineration at appropriate temperature in licensed facilities may be suitable. Empty containers should be triple-rinsed and disposed of according to local regulations. Maintain disposal records for regulatory compliance.

This compound is classified as ADR Class 9 (Miscellaneous dangerous goods), Packing Group III, indicating moderate transport hazard.
