Transportation & Storage
1. Transported as non dangerous goods.
2. It is volatile, pay attention to the tightness of the product during storage and transportation.
3. It should be stored in a closed high-density polyethylene tank or tin tank with internal coating and placed in a clean, dry warehouse.
4. Keep the container closed to prevent high temperature and sunlight, away from heat source, fire source and acid, alkali, strong oxidants, etc.
5. Avoiding violent vibration during transportation and avoiding upside-down when stacking.
