	ACUTE HAZARDS	PREVENTION	FIRE FIGHTING
FIRE & EXPLOSION	Not combustible. See Notes.		In case of fire in the surroundings, use appropriate extinguishing media. In case of fire: keep drums, etc., cool by spraying with water.

STRICT HYGIENE! IN ALL CASES CONSULT A DOCTOR!
	SYMPTOMS	PREVENTION	FIRST AID
Inhalation	Cough. Sore throat. Burning sensation. Laboured breathing. Shortness of breath.	Use ventilation, local exhaust or breathing protection.	Fresh air, rest. Artificial respiration may be needed. Refer for medical attention.
Skin	Redness. Pain. Blisters. Serious skin burns.	Protective gloves. Protective clothing.	Remove contaminated clothes. Rinse skin with plenty of water or shower for at least 15 minutes. Refer immediately for medical attention .
Eyes	Redness. Pain. Blurred vision. Severe burns.	Wear face shield or eye protection in combination with breathing protection.	Rinse with plenty of water for several minutes (remove contact lenses if easily possible). Refer immediately for medical attention.
Ingestion	Sore throat. Vomiting. Abdominal pain.	Do not eat, drink, or smoke during work.	Rinse mouth. Do NOT induce vomiting. Give one or two glasses of water to drink. Refer for medical attention .

SPILLAGE DISPOSAL	CLASSIFICATION & LABELLING
Evacuate danger area! Consult an expert! Personal protection: complete protective clothing including self-contained breathing apparatus. Ventilation. Do NOT let this chemical enter the environment. Cautiously neutralize spilled liquid with dilute acid such as dilute sulfuric acid. Wash away remainder with plenty of water.	According to UN GHS Criteria May be corrosive to metals Harmful if swallowed Causes severe skin burns and eye damage May cause respiratory irritation Very toxic to aquatic life Transportation UN Classification UN Hazard Class: 8; UN Pack Group: III
STORAGE
Store in an area without drain or sewer access. Separated from food and feedstuffs. See Chemical Dangers. Cool. Well closed. Keep in a well-ventilated room. Provision to contain effluent from fire extinguishing. See Notes.
PACKAGING
Unbreakable packaging. Put breakable packaging into closed unbreakable container. Do not transport with food and feedstuffs.

AMMONIUM HYDROXIDE (10%-35% solution)

ICSC: 0215

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance VERY VOLATILE COLOURLESS AMMONIA SOLUTION IN WATER WITH PUNGENT ODOUR. Physical dangers Chemical dangers Reacts with many heavy metals and heavy metal salts. This produces explosive compounds. Attacks many metals. This produces flammable/explosive gas (hydrogen - see ICSC 0001). It reacts violently with acids. This generates fire and explosion hazard. Decomposes on heating. This produces toxic and corrosive fumes including ammonia and nitrogen oxides. This generates toxic hazard.	Formula: NH₄OH Molecular mass: 35.1 Boiling point: 38°C (25%) Melting point: -58°C (25%) Relative density (water = 1): 0.9 (25%) Solubility in water: miscible Vapour pressure, kPa at 20°C: 48 (25%) Relative vapour density (air = 1): 0.6 See Notes.

EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation of its aerosol or vapour and by ingestion. Effects of short-term exposure The substance is corrosive to the eyes, skin and respiratory tract. Corrosive on ingestion. Inhalation of high concentrations of the vapour may cause laryngeal oedema, inflammation of the respiratory tract and pneumonia. Exposure could cause asphyxiation due to swelling in the throat. The effects may be delayed.	Inhalation risk A harmful contamination of the air can be reached very quickly on evaporation of this substance at 20°C. Effects of long-term or repeated exposure Repeated or prolonged inhalation may cause effects on the lungs.

EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body by inhalation of its aerosol or vapour and by ingestion.

Effects of short-term exposure
The substance is corrosive to the eyes, skin and respiratory tract. Corrosive on ingestion. Inhalation of high concentrations of the vapour may cause laryngeal oedema, inflammation of the respiratory tract and pneumonia. Exposure could cause asphyxiation due to swelling in the throat.

Inhalation risk
A harmful contamination of the air can be reached very quickly on evaporation of this substance at 20°C.

Effects of long-term or repeated exposure
Repeated or prolonged inhalation may cause effects on the lungs.

OCCUPATIONAL EXPOSURE LIMITS
TLV: 18 mg/m³, 25 ppm, as TWA; 27 mg/m³ as STEL. MAK: 14 mg/m³, 20 ppm; peak limitation category: I(2); pregnancy risk group: C

ENVIRONMENT
The substance is very toxic to aquatic organisms.

NOTES
Be aware that ammonia gas can evolve from ammonia solution. Ammonia vapour is flammable and explosive under certain conditions. See ICSC 0414. Do NOT completely fill bottles with the substance; strong solutions may develop pressure. Release caps with care. Melting points range from -3°C (4%) to -69°C (28%). Another boiling point is 25°C (32%). Other UN numbers are: UN 2073 Ammonia solution, relative density of less than 0.880 at 15°C in water, with more than 35% but no more than 50% ammonia; UN 3318 Ammonia solution, relative density of less than 0.880 at 15°C in water, with more than 50% ammonia. Depending on the degree of exposure, periodic medical examination is suggested.
