Safe handling requires appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing due to its Skin Sens. 1 classification. Work in well-ventilated areas or under fume extraction to minimize inhalation exposure. Avoid direct skin contact and implement proper hygiene measures. Use non-sparking tools and ensure grounding of equipment. Train personnel on emergency procedures and maintain eyewash stations and safety showers in the work area.

Store the compound in a cool, dry, well-ventilated area away from heat sources, direct sunlight, and incompatible materials. Use tightly sealed original containers made of compatible materials. Maintain temperatures within manufacturer specifications and ensure proper segregation from oxidizing agents and strong acids. Implement appropriate fire prevention measures and ensure storage areas comply with local regulations for hazardous substances. Regular inspection of container integrity is recommended.

Immediate action involves removing contaminated clothing and washing affected skin thoroughly with soap and water for at least 15 minutes. For eye contact, flush immediately with clean water for 15-20 minutes while holding eyelids open. If inhaled, move to fresh air immediately. Seek medical attention promptly, especially for skin sensitization reactions. Never induce vomiting if ingested. Keep the safety data sheet available for medical personnel and contact poison control if necessary.

Disposal must comply with local, national, and EU waste regulations due to its environmental classification as Aquatic Chronic 2. Contact authorized waste management companies for proper disposal through licensed facilities. Do not discharge to sewers, waterways, or soil. Incineration at appropriate high-temperature facilities may be required. Maintain waste documentation and tracking records. Consult with regulatory authorities and waste disposal experts to ensure compliance with all applicable environmental protection laws.

Transport follows ADR classification as Class 9 (Miscellaneous dangerous goods), Packing Group III, indicating lower relative danger level. Use appropriate UN-specification packaging designed for Class 9 materials. Ensure proper labeling with GHS pictograms (GHS07, GHS08, GHS09) and hazard information. Transport vehicles must carry appropriate documentation, emergency response information, and comply with routing restrictions. Only use certified dangerous goods transporters familiar with Class 9 requirements.

The compound is subject to EU REACH and CLP regulations requiring proper registration, classification, and labeling. It is not currently listed as a Substance of Very High Concern (SVHC). Compliance with occupational safety regulations is mandatory due to its STOT RE 2 and Skin Sens. 1 classifications. Environmental regulations apply given its Aquatic Chronic 2 status. Users must maintain safety data sheets, implement risk assessments, and follow worker protection measures as required by chemical safety legislation.
