Name: sodium hydrosulphide

Other names: ACID SODIUM SULPHIDE, SODIUM SULPHYDRATE, SODIUM BISULPHIDE Formula: NaHS Group: industrial chemistry Look: white or colourless hygroscopic crystals Supplier: LLC Company Plazma ® Producer: China, Germany Sodium hydrosulphide represents white or colourless hygroscopic crystals well water soluble. Forms crystalline hydrates. Is poorly hydrolyzable salt - acid salt of sodium and hydrogen sulfide. Melts without decomposition, in flux sodium hydrosulphide has black color. The typical reducer, is oxidized air oxygen. Density is 1,79 g/cm ³. Temperature of melting is 350 °C.

Sodium hydrosulphide (sodium sulphydrate, acid sodium sulfide, sodium bisulphide) is received absorption of hydrogen sulfide gas (withdrawal of different productions - carbon sulfur, 2 mercaptobenzothiazoles) sodium hydroxide solution.

Sodium hydrosulphide safety requirements

Sodium hydrosulphide is fire and explosion-proof, on extent of impact on organism belongs to substances of the 4th class of danger.

It is dangerous at inhalation (cough, constraint in breasts, cold, dacryagogue); hit on skin (skin burn); hit in eyes (the century, sharp reddening of conjunctiva, defeat of iris of the eye has swelled). Chemical burn.
Danger of sodium hydrosulphide is caused by possibility of allocation from hydrogen sulfide solution at long-term storage or action of high temperature.
At concentration, above limit admissible rate, hydrogen sulfide affects annoyingly eyes and airways, can cause respiratory standstill. At inhalation of 1 mg/l and above poisoning can develop almost instantly: spasms and loss of consciousness lead to lethal outcome.

For chemical investigation and the head of works - PDU-3 (within 20 minutes). For emergency crews - the isolating protective KIH-5 suit complete with the isolating gas mask of IP-4M or the respiratory device ASV-2. In the absence of the specified samples - protective general L-1 or L-2 suit complete with industrial gas mask with cartridges In with the aerosol filter, BKF, CD, KD8.
At small concentration in air (when exceeding maximum concentration limit to 100 times) - overalls, industrial gas mask of small dimension of PFM-1 with the universal protective boss of ROM, autonomous protective individual set with forced feed in zone of breath of cleaned air. Maslobenzostoyky gloves, gloves from butyl rubber dispersion, special footwear.
Overalls, respirators, safety spectacles, gloves, protective ointments, pastes, silicone cream, gas mask with BKF brand box. It is necessary to follow rules of personal hygiene, after completion of work to take shower.

Packaging, transportation and storage.

Sodium hydrosulphide is packed into polypropylene bags weighing 25 kg.
Sodium hydrosulphide is transported car sendings by railway transport or small sendings automobile and river means of transport in the covered vehicles.
Sodium hydrosulphide store in the closed dry warehouse on wooden racks or pallets at relative humidity of air no more than 70%. Allocation from hydrogen sulfide sodium hydrosulphide solution therefore storage of sodium hydrosulphide together with liquids, especially acids is inadmissible is possible.
Warranty period of storage of product - 1 year from the date of production.

LLC Company Plazma ® carries out deliveries of chemical products from warehouse in Kharkiv in terms and for reasonable prices, on conditions, favorable to you.
