SODIUM SULFHYDRATE FIREFIGHTING MEASURES
Suitable extinguishing media:Use foam,dry powder or water spray.
Special hazards arising from the chemical:This material may decompose and burn at high Temperature and fire and release toxic fumes.
Special protective actions for fire-fighters: Wear self-contained breathing apparatus for firefighting if necessary.Use water spray to cool unopened containers. In case of fire in the surroundings,use appropriate extinguishing media.
SODIUM HYDROSULPHIDE ACCIDENTALRELEASE MEASURES
a.Personal precautions ,protective equipment and emergency procedures : It is recommended that emergency personnel wear
protective masks and fire protective overalls.Do not touch the spill directly.
b.Environmental precautions:Isolate contaminated areas and restrict access.
C.Methods and materials for containment and cleaning up:Small amount of leakage: adsorption with sand or other inert materials. Do not allow products to enter restricted areas such as sewers. A large amount of leakage: building a dike or digging a pit to contain.
Transfer to a tank truck or Special collector with a pump and transport to awaste disposal site for disposal.
Sodium hydrosulfide solution
Sodium hydrosulfide solution concentration: 32%, 45%. It can be prepared according to customer requirements. The product is generally orange or colorless. It is easy to deliquesce. It releases hydrogen sulfide when it decomposes at the melting point. It is easily soluble in water and alcohol. It is used in the dye industry to synthesize organic intermediates and as an auxiliary agent for preparing sulfur dyes. It is used in the leather industry for dehairing and tanning raw hides. It is used in the fertilizer industry to remove monomer sulfur in activated carbon desulfurizers. It is widely used in the mining industry for copper ore dressing. It is used for sulfite dyeing in the production of artificial fibers. It is a raw material for the manufacture of ammonium sulfide and pesticide ethyl mercaptan semi-finished products. It is also used for wastewater treatment.
In the next three years, we are committed to becoming one of the top ten export enterprises in China’s fine daily chemical industry, serving the world with high-quality products and achieving a win-win situation with more customers.
