Safe handling requires comprehensive personal protective equipment including chemical-resistant gloves, safety goggles, and respiratory protection due to its Acute Tox. 3 classification. Work should be conducted in well-ventilated areas or under fume extraction systems. Avoid skin contact, inhalation, and ingestion. Emergency washing facilities must be readily accessible. Training on proper handling procedures for acutely toxic substances is essential before use.

Proper storage requires cool, dry, well-ventilated areas away from heat sources and incompatible materials. Containers must be tightly sealed and properly labeled with appropriate hazard warnings. Given its acute toxicity classification, access should be restricted to authorized personnel only. Storage areas should comply with local regulations for toxic substances and include appropriate emergency response equipment and spill containment measures.

Immediate action is critical due to acute toxicity. For skin contact, remove contaminated clothing and wash affected area thoroughly with soap and water. In case of eye contact, rinse immediately with plenty of water for at least 15 minutes. If inhaled, move person to fresh air immediately. For ingestion, do not induce vomiting and seek immediate medical attention. Contact poison control center and provide safety data sheet information.

Disposal must comply with local and national hazardous waste regulations due to its acute toxicity and environmental hazard classification. The substance requires treatment as toxic chemical waste and disposal through licensed hazardous waste contractors. Incineration at authorized facilities capable of handling organophosphorus compounds is typically required. Never dispose of via regular waste streams or drain systems due to aquatic toxicity concerns.

Transportation falls under ADR Class 6.1 (toxic substances), Packing Group III regulations. Packages must bear appropriate dangerous goods labels including GHS06 and GHS09 pictograms with 'Danger' signal word. Proper shipping documentation, emergency response information, and driver training for toxic substance transport are mandatory. Vehicles must comply with ADR requirements for Class 6.1 substances including appropriate emergency equipment.

Yes, the substance is subject to REACH registration requirements for chemical substances in Europe and must comply with CLP regulation for classification and labeling. While not currently listed as SVHC, its acute toxicity classification requires compliance with workplace safety regulations and environmental protection measures. Import/export may require permits due to its toxic nature, and users must maintain safety data sheets and exposure assessments.
