STORAGE AND TRANSPORT INFORMATION

Packing Group: II

Usually commodity with inhibitor.Store in a cool, ventilated warehouse. Away from fire and heat source. Warehouse temperature should not be more than 10 ℃. Packing seal, do not contact with air. Should be stored apart and antioxidant. Storage room lighting, ventilation, equipment use explosion-proof type. Technical measures for fire and explosion prevention should be used when tank storage. Banning the use of easy to produce the spark of loading and unloading machinery and tools. Summer best transportation sooner or later. Light light discharge when handling to prevent damage to packaging and container.
