SECTION 2: Hazards identification

Substances classification Gases under pressure, Liquefied gas Corrosion/irritation of skin, Category 1A Acute toxicity - Oral, Category 3 Acute toxicity - Dermal, Category 3 Acute toxicity - inhalation, Category 3 Toxicity to organs - specific targets - Single Exposure - Category 1 Toxicity to organs - specific targets - Repeat Exposure - Category 2 Serious eye damage / eye irritation - Category 1 Sensitization respiratory, Category 1 Skin sensitization, category 1 - subcategory 1A and 1B Aspiration hazard, Category 1 Dangerous to the aquatic environment- Acute, Category 1 Germ cell mutagenicity, Category 2

Most important adverse effects

Liquefied gas under pressure, toxic and aggressive to the environment, with extremely pungent odor, which makes it easy to detect by smell even at low concentrations. Due to the great solubility in water, ammonia, in gaseous form, dissolves in the mucous membranes of the eyes and respiratory tract, exerting an intense irritating effect and cellular damage by its alkaline caustic action. Effects of the product: Toxic effects to the human health. Adverse effects to the human health: Contact with liquid ammonia can cause severe eye and skin burns. Its toxic action on the mucous membranes interrupts breathing and prevents vision, even at low concentrations. It can cause burning and asphyxiation. The 500 ppm concentration causes irritation in the throat. 2000 ppm is dangerous for small exposure and 5000 ppm can be fatal even in the case of brief exposure. Inhalation: Inhalation of gaseous ammonia, in large concentrations, can cause death. Eye contact: Liquid ammonia can cause severe eye burns and impair vision even at low concentrations in the gas phase. Skin contact: Liquid ammonia is a skin irritant that can cause skin burns. Ingestion: It causes corrosion and immediate damage to the gastrointestinal tract. Burns: Liquid ammonia can cause skin burns. Adverse Effects on the Environment: Because it is very soluble in water and, even in low concentrations, it is harmful to aquatic life. Exposed animals may suffer tissue damage and be put to death. Burn the plants by dehydration.

Other physicochemical hazards

Ammonia is an alkaline product that releases heat when it reacts with acid. In contact with halogens, boron, alkyl sulfates 1.2 dichloroethane, ethylene oxides, platinum, nitrogen trichloride and strong oxidizers, can cause extremely exothermic or explosive reactions. In contact with heavy metals and their compounds can form explosive products. In contact with chlorine and its compounds, the release of chlorine gas may result. Ammonia can produce a significant explosive mixture when in contact with hydrocarbons. The product is also incompatible with acetic aldehyde, acrolein, hydrazine and potassium ferrocyanide. Specific hazards: Ammonia vaporizes quickly. Gas is lighter than air. Ammonia is stable when stored and used under normal storage and handling conditions. Above 450°C it can decompose, releasing nitrogen and hydrogen, the latter is highly flammable. Polymerization does not occur. Main symptoms: Inhalation can cause breathing difficulties, bronchospasm, burns in the mucous membranes of the mouth, pharynx and larynx, constriction and chest pain and salivation. Depending of the concentration and time of exposure, the respiratory condition may progress with edema and glottis spasm, asphyxia, cyanosis, pulmonary edema, respiratory arrest and death. The liquid Ammonia contact with skin may cause serious burns. Exposure of the eyes to Ammonia in gaseous form can cause lacrimation eyes, redness and swelling of the eyelids. Accidents with liquid ammonia in the eyes are always serious and can cause permanent loss of vision. Repeated exposure to the product can cause chronic bronchitis. Symptoms of ammonia intoxication begin with irritation of the eyes, nose and throat, followed by cough, suffocation, chest pain and vomiting. Emergency Overview: Depending of the proportions, , isolate and evacuate the area. Try to block the leak or transfer the product. Stay with the wind blowing at his back. People must only be allowed access to contaminated areas if they are using protective clothing and a mask with an air supply. GHS labeling elements, including precautionary phrases:
