| Proper storage is crucial for maintaining product quality and ensuring operational safety. The following are general storage principles: Dedicated Areas: Dangerous chemicals should be stored in designated warehouses or areas that meet safety standards, away from residential zones and densely populated areas. Segregated Storage: Strictly classify and segregate products according to their hazard class to prevent incompatible substances from being stored together and causing dangerous reactions (e.g., acids and bases separated, flammables away from oxidizers). Good Ventilation: Storage areas should maintain good natural or forced ventilation to prevent the accumulation of hazardous gases or vapors. Temperature & Humidity Control: Control the temperature and humidity of the storage environment according to the recommendations in the SDS. Avoid direct sunlight and extreme temperatures. Fire and Explosion Prevention: Storage areas for flammable and explosive products should be equipped with adequate fire-fighting equipment, prohibit open flames, and ensure electrical equipment meets explosion-proof standards. Clear Labeling: All storage containers and areas should have clear, conspicuous hazard labels and warning signs. Spill Response: Storage areas should be equipped with appropriate spill response equipment and materials, and personnel should be familiar with emergency procedures. Regular Inspections: Periodically inspect the integrity of storage containers to ensure no leaks or damage, and verify label information. Away from Food and Drinking Water: Avoid cross-contamination.
