Sodium Sulphite

We are actively engaged as Manufacturer, Supplier, and Exporter of Sodium Sulphite in India. Sodium Sulphite is an industrial chemical widely used for its strong reducing and anti-oxidizing properties in sectors such as water treatment, pulp and paper, textiles, and photography. It plays a key role in oxygen removal, bleaching, and chemical preservation processes.

Sodium Sulphite is also known (synonyms) as: Disodium Sulphite, Sulfurous Acid Disodium Salt, Sodium Sulfite Anhydrous, and Anti-Chlor Agent. It is generally supplied in white crystalline or powder form and is available in both technical and food-grade variants, depending on the intended application.

Fire and Explosion

Flammability of the Product: NON-FLAMMABLE.

Flash Points °C: Above 75 °C.

Various substances: Not applicable

Fire & explosive hazards: When heated, Sulphur dioxide vapor will evolve. Further heating may cause rapid thermal decomposition resulting of heat, Sulphur dioxide and associated pressure. Keep container/storage vessels in fire area cooled with water spray.

Firefighting equipment: Wear self-contained breathing apparatus, pressure demand and full protective gear.

Special remarks on Fire Hazards: Not available.

Exposure Controls, Personal Protection

Engineering Control: Provide exhaust ventilation or other engineering controls to keep the airborne concentration of vapors below their respective threshold limit value.

Personal protection: Face shield. Full suit. Vapor respirator. Be sure to use an approved/ certified respirator or equivalent. Gloves, boots.

Personal protection in case of a large spill: Splash goggles. Full suit. Vapor respirator. Boot. Gloves. A self-contained breathing apparatus should be used to avoid inhalation of the product. Suggested protective clothing might not be sufficient; consult a specialist before handling this product.

Exposure limits: Not Available

Accidental Release Data

Small Spill: Dilute with water and mop up, or absorb with an inert dry material and place in an appropriate waste disposal container.

Large Spill: Confine area to qualified personnel. Wear proper protective equipment. Stop leak if safe to do so. Absorb with dry earth, sand or other non-combustible material. Do not get water inside container. Do no touch spilled material. Use water spray curtain to divert vapor drift. Prevent entry into sewers, basements or confined

areas; dike if needed. Call for assistance on disposal.

Handling and Storage
