1. Leak-Proof Containers: Select corrosion-resistant, leak-proof containers compatible with the chemical properties of the leaching agent (liquid or solid) to prevent leakage during transportation and storage. Material reactivity with the leaching agent must be strictly avoided.
2. Labeling: Clearly label the outer packaging with the product name, composition, hazard symbols (if applicable), production date, expiration date, and a Material Safety Data Sheet (MSDS) for immediate safety reference.
3. Structural Integrity: Design pressure-resistant and shock-absorbent packaging based on the physical state (liquid/solid) of the leaching agent. Reinforce support structures for heavy-duty packaging to prevent damage during transit.
4. Environmental Controls: Maintain a dry, well-ventilated storage environment with temperature regulated between15–25°C. Avoid humidity and high temperatures to prevent decomposition or caking. For flammable agents, implement explosion-proof facilities and keep away ignition sources.
5. Safety Protocols: Operators must wear protective gear (gloves, goggles) and ensure emergency equipment (adsorbents, fire extinguishers) is accessible. Follow MSDS procedures immediately for spill containment and disposal.Special Considerations:- Volatile/Oxidizing Components: Agents containing ammonia, thiosulfates, or other volatile/oxidizing substances require light-resistant storage and continuous monitoring of airborne vapor concentrations to prevent toxic buildup.- Long-Term Storage: Conduct periodic sampling and testing to verify physicochemical stability and ensure no degradation of active components.This translation adheres to industry standards for chemical safety, integrating technical accuracy with regulatory compliance.
