Benzene-1,3-diamine;dihydrochloride should be stored in a cool, dry, well-ventilated area away from direct sunlight and heat sources. The substance must be kept in tightly sealed containers to prevent moisture absorption and contamination. Storage areas should be equipped with appropriate spill containment measures and restricted access due to the substance's hazardous nature. Incompatible materials such as strong oxidizing agents should be stored separately to prevent dangerous reactions.

Benzene-1,3-diamine;dihydrochloride exposure requires immediate action depending on the contact route. For skin contact, immediately remove contaminated clothing and flush the affected area with plenty of water for at least 15 minutes. In case of eye contact, rinse thoroughly with water and seek medical attention due to its Eye Irrit. 2 classification. If inhaled, move the person to fresh air immediately. For ingestion, do not induce vomiting and seek immediate medical attention due to acute toxicity concerns.

Benzene-1,3-diamine;dihydrochloride disposal must comply with local and European hazardous waste regulations due to its toxic and mutagenic properties. The substance cannot be disposed of through regular waste streams and requires specialized hazardous waste treatment facilities. Containers should be properly labeled and handled by certified waste management companies. Incineration at appropriate temperatures or chemical treatment may be required. Always consult local environmental authorities for specific disposal requirements and authorized disposal facilities.

Benzene-1,3-diamine;dihydrochloride is classified under ADR Class 6.1 (Toxic substances), Packing Group III for transportation purposes. Shipments must comply with dangerous goods regulations including proper packaging, labeling, and documentation. Vehicles must display appropriate hazard placards and drivers require ADR certification. The substance must be packaged in UN-approved containers and accompanied by proper shipping papers. Emergency response information and safety data sheets must be available during transport.
