Detailed Product Description

Features:
1) Applications:
a) Widely used in the textile industry for vat dyeing, reduction cleaning,
printing and stripping, and textile materials bleaching
b) Also used in bleaching paper pulps, especially mechanical pulp, and
bleaching kaolin clay and foodstuffs
c) As a reducing agent, it is used in organic synthesizing
2) Specific hazards: Our sodium hydrosulfite is highly stable when stored in
dry closed containers. However, all sodium hydrosulfite by nature is a very
reactive chemical which can decompose when exposed to air and moisture
or contacts with small quantities of water. Decomposition will result in
spontaneously ignition and liberating toxic gas-SO₂. It also
reacts violently with oxidants which will lead to combustion or explosion
3) Extinguishing media: a large amount of water
4) Extinguish method:
a) Using sufficient amount of water drown the product completely
b) Other extinguishing media may not stop decomposition thoroughly
5) Storage and handling:
a) Must be always handled and stored in sealed clean iron drums or bulk
containers
b) Avoid contacts with moisture, acids, oxidizing chemicals and combustible
organic substances
c) Protect the product away from direct sunlight, heat, sparks and open flames
d) Carefully handle the product and avoid damaging the package
6) Spillage:
a) Sweep up immediately all spillage of sodium hydrosulfite around the
application and storage areas
b) Deposit it in a dry and clean container where it can be dissolved in water
c) Wash the area involved with water
d) If the product is suspected to already absorbed moisture, use it as soon
as possible (if it is impossible to use it immediately, you need to dispose it)
