Ammonium sulphide solution 42-44%

Supply fresh air or oxygen; call for doctor. In case of unconsciousness place patient stably in side position for transportation.

Symptoms: Irritation to the respiratory system.

Treat affected skin with cotton wool or cellulose. Then wash and rinse thoroughly with water and a mild cleaning agent. Immediately wash with water and soap and rinse thoroughly for at least 15 min. If skin irritation continues, consult a doctor.

Symptoms: Irritation, dermatitis or sensitisation (from repeated or continuous contact).

Rinse opened eye for several minutes under running water. Then consult a doctor.

Symptoms: Irritation to the eyes.

If victim is conscious: Rinse mouth. Do not induce vomiting. Never give anything by mouth to an unconscious person. Drink plenty of water and provide fresh air. Call for a doctor immediately.

Symptoms: Formation of hydrogen sulphide in the stomach due to the acidic pH value.

Powder, CO2, Water spray

Never use direct water jet, since this can lead to a strong evaporation and violent extrusion. This can expand the fire.

The solution is easily flammable. Vapour air mixture forms explosion-dangerous mixtures. The formation of dangerous gases or vapours e. g. hydrogen sulphide (H2S), ammonia (NH3), nitrous gases (NOx) and sulphur dioxide (SO2) must be expected. Vapours are heavier than air. During heating or in case of fire poisonous gases are produced.

Increase of pressure and danger of explosion in case of heating up of the containers. Water spray may be used to keep fire exposed containers cool. If possible remove containers from the danger area. Never use direct water jet, since this can lead to a strong evaporation and violent extrusion. This can expand the fire. Burning liquids can be extinguished by diluting with water. Pay attention to reignition.

Check for gas alarm both acoustic and optical; if so, keep out of areas indicated with sign "hazardous vapours", follow emergency plan or evacuation. Have emergency equipment ready for absorbing spillage. Check for complete evacuation of people; have ventilation sufficient to avoid explosive atmosphere; ignition sources to be checked for and removed; check for static electricity; check for leaks and sources of H2S vapour; Prevent spillage from entering drains and sewage system to avoid danger of explosive atmosphere.

Convert small quantities with a solution of 1% hydrogen peroxide (H2O2) into sulphate. (Regulate temperature by adjusting the rate of addition of H2O2. Ensure pH range of 10 to 11. Leave for 12 hours. Then neutralize). Check for temperature increases.

Pump off larger quantities.

Polluted wash water has to be hold back and disposed of. Prevent entry into watercourses, sewers (explosion hazard!) and soil. With the penetration of larger quantities into the underground and waters the endangerment of the drinking water is possible. Inform responsible authorities. Do not allow product to reach sewage system or any water course. Inform respective authorities in case of seepage into water course or sewage system. Dilute with plenty of water. Do not allow to enter sewers/ surface or ground water.

Absorb spillage with liquid-binding material and dispose of as special waste. Then aerate affected area and clean contaminated objects and floor thoroughly with regard to environmental regulations. Convert small quantities with a solution of 1% hydrogen peroxide (H2O2) into sulphate. Use neutralising agent.

Materials: liquid-binding material (Sand, Chemizorb, Kieselgur, Rench Rapid, sand, diatomite, acid binders, universal binders, sawdust)

Open and handle receptacle with care. Prevent formation of aerosols.

Store in original container unopened. Keep container tightly closed. Store cool, away from sources of ignition or heat, in ventilated area. Ventilation according to local administrative requirements. Check for feasibility of fast and safe evacuation. Safety labeling of containers and storage areas. Wear PPE with independent air supply for breathing. For charging and discharging use strictly tight equipment and an exhaust ventilation system. Avoid access of air and oxygen. Maximum storage temperature: 30 °C. Do not store together with acids, acidic salts or oxidizing materials. Storage class 3. Store only in the original receptacle. Store in a cool location. Keep container tightly sealed. Store in cool, dry conditions in well sealed receptacles.

Keep ignition sources away - Do not smoke.

Ensure adequate ventilation especially in closed rooms. Provide local ventilation appropriate to the product decomposition risk (see section "Stability and reactivity"). Monitor air concentrations at the workplace. Apply technical measures to comply with the occupational exposure limits: ventilation, closed systems with lower pressure. To avoid ignition of H2S-containing atmosphere choose electrical and other possible sources of ignition corresponding to zone requirements. Use process enclosures, local exhaust ventilation, or other engineering controls to keep air levels below recommended exposure limits. Make regular concentration measurements at the workplace. A warning system for gases is recommended. In closed rooms in particular at increased temperature provide sufficient ventilation. While handling a personal H2S-detector is recommended. Suitable protective mask to be held ready at the workplace. It is suggested to wear personal H2S-Detector during handling. Carry emergency gas mask for escape.

Wear gloves. Adequate material: butyl rubber (0.5 mm), fluororubber (0.4 mm), penetration time of glove material: > 8 h with permanent contact. Protective gloves. The glove material has to be impermeable and resistant to the product/ the substance/ the preparation. Due to missing tests no recommendation to the glove material can be given for the product/ the preparation/ the chemical mixture. Selection of the glove material on consideration of the penetration times, rates of diffusion and the degradation. Material of gloves: Butyl rubber, BR; Fluorocarbon rubber (Viton). The selection of the suitable gloves does not only depend on the material, but also on further marks of quality and varies from manufacturer to manufacturer. As the product is a preparation of several substances, the resistance of the glove material can not be calculated in advance and has therefore to be checked prior to the application. Penetration time of glove material: > 8 h with permanent contact. The exact break trough time has to be found out by the manufacturer of the protective gloves and has to be observed.

Face protection. Have emergency eye-wash units and safety shower in work area. Tightly sealed goggles.

If vapours or aerosols occur full mask with combination filter is necessary (type ABEK-P2). In case of brief exposure or low pollution use respiratory filter device. In case of intensive or longer exposure use self-contained respiratory protective device. Mandatory mask.

Wear suitable chemical protection suit (alkali-resistant) to prevent skin contact. Wear flame-retardant, antistatic protective clothing.

Stable under normal conditions of use, storage and transport. Thermal decomposition / conditions to be avoided: With heating the solution forms combustible vapours.

Ammonium hydrosulphide solution decomposes easily into ammonia and hydrogen sulphide at room temperature. Stable under normal conditions of use, storage and transport.

With air an explosive atmosphere may be formed. Developing of ammonia (NH3) and hydrogen sulphide (H2S) already at room temperatures.

Accumulation of heat / temperatures > 30 °C (otherwise release of toxic and highly flammable H2S). open containers, exposure to air, enter sewer system, Sources of ignition (mechanical, electrostatic, sparks, etc.)

Acids, oxidants and metals e.g. copper and copper alloys, aluminium, zinc and zinc alloys (release of H2S and if in contact with metals release of H2)
