Packing:

Bulk

Storage:

Stored at low temperature and well ventilated place, kept away from open fire, heat source and direct sunlight, and also separated from oxidizer, halogen (fluorine, chorine, bromine) and acid. The lighting and ventilation equipment for warehouse shall be of explosion-proof type, with switch located outside the house.

Transportation:

As hazardous matters class I, the bulk can be handed by tank truck.

Safety Precautions:

1. The product is inflammable, explosive with explosion limit, in atmosphere, of 2.6-10.3% (v/v), vapor flash point -28. It belongs to class I inflammables in respect of fire hazard classification, and to category 3.1 in respect of hazard classification. Therefore, all precautions shall take into account the possibility to avoid formation of explosive atmosphere and making contact within nitric acid, sulfuric acid, chlorosulfonic acid.
2. Initial fire due to meta-pentaidene can be extinguished with foam, fry powder, or CO2 or sand earth, but no water.
3. The product has a rather low boiling point, so that it should be stored in a cool and dry place. Measures like spraying water shall be taken during summer when it would be placed outdoor and do not transport it at noon when temperature would be high.

4. Truck for product transportation shall have hazardous material mark and necessary safety pretection.

5. Product vapor is somewhat toxic; Inhalation of certain amount of its vapor will cause physical discomfort, therefore the working place shall be kept at a good condition with ventilation and equipped with shower. If a person feels discomfort evidently, he should leave the site immediately o get fresh air; if breath becomes difficult, oxygen shall be given. If breath stops, artificial breathing shall be made.
