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: Mists, vapours, droplets or sprays can cause 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. If skin irritation continues, consult a doctor. Immediately wash with water and soap and rinse thoroughly for at least 15 min.

Symptoms: Repeated or continuous contact with the skin may cause irritation, dermatitis or sensitisation.

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

Symptoms: Mists, vapours, droplets or sprays can cause irritation to the eyes.

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

Symptoms: When swallowed, hydrogen sulphide is formed 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.

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. Burning liquids can be extinguished by diluting with water. Pay attention to reignition. Fight escaping vapours with water spray.

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.

Convert small quantities with a solution of 1% hydrogen peroxide (H2O2) into sulphate.

Pump off larger quantities.

Polluted wash water has to be hold back and disposed of. Prevent entry into watercourses, sewers (explosion hazard!) and soil.

Absorb spillage with liquid-binding material, aerate affected area and clean contaminated objects and floor thoroughly.

Materials: 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.

Keep ignition sources away - Do not smoke. Protect against electrostatic charges.

Ensure adequate ventilation especially in closed rooms. Provide local ventilation appropriate to the product decomposition risk. Monitor air concentrations at the workplace. Apply technical measures to comply with the occupational exposure limits: ventilation, closed systems with lower pressure. 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.

Wear gloves. Adequate material: butyl rubber (0.5 mm), fluororubber (0.4 mm), penetration time of glove material: > 8 h with permanent contact. The glove material has to be impermeable and resistant to the product/ the substance/ the preparation. Material of gloves: Butyl rubber, BR, Fluorocarbon rubber (Viton).

Face protection. Tightly sealed goggles.

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. 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.

Ammonium hydrosulphide solution decomposes easily into ammonia and hydrogen sulphide at room temperature.

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)
