             Packaging and Storage
             Supplied in bulk, and drums of approximately 208 litres. Ensure drums are tightly re-sealed after use.
             All packages should be stored under cover. Where outside storage is unavoidable drums should be laid horizontally to
             avoid the possible ingress of water and the obliteration of drum markings.
             Products should not be stored above 60°C, exposed to hot sun or freezing conditions.
