    4.2 Most important symptoms/effects, acute and delayed

    Excerpt from ERG Guide 125 [Gases - Corrosive]: TOXIC; may be fatal if inhaled, ingested or absorbed through skin. Vapors are extremely irritating and corrosive. Contact with gas or liquefied gas may cause burns, severe injury and/or frostbite. Fire will produce irritating, corrosive and/or toxic gases. Runoff from fire control may cause pollution. (ERG, 2016)

    Vapors cause irritation of eyes and respiratory tract. Liquid will burn skin and eyes. Poisonous; may be fatal if inhaled. Contact may cause burns to skin and eyes. Contact with liquid may cause frostbite. (EPA, 1998)

    Excerpt from ERG Guide 154 [Substances - Toxic and/or Corrosive (Non-Combustible)]: TOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution. (ERG, 2016)

    4.3 Indication of immediate medical attention and special treatment needed, if necessary

    Inhalation of ammonia gas: Observe carefully for signs of progressive upper airway obstruction, and intubate early if necessary. Administer humidified supplemental oxygen and bronchodilators for wheezing. Treat noncardiogenic pulmonary edema if it occurs. Asymptomatic or mildly symptomatic patients may be discharged after a brief observation period. Ingestion of aqueous solution: If a solution of 10% or greater has been ingested or if ther are any symptoms of corrosive injury (dysphagia, drooling, or pain), perform flexible endoscopy to evaluate for serious esophageal or gastric injury. Obtain chest and abdominal radiograph to look for mediastinal or abdominal free air, which suggests esophageal or gastrointestinal perforation. Eye exposure: After eye irrigation, perform fluorescein examination and refer the patient to an ophthalmologist if there is evidence of corneal injury.

    5.Fire-fighting measures

    5.1 Extinguishing media

    Suitable extinguishing media

    Suitable extinguishing media: Use water spray, alcohol-resistant foam, dry chemical or carbon dioxide.

    5.2 Specific hazards arising from the chemical

    Excerpt from ERG Guide 125 [Gases - Corrosive]: Some may burn but none ignite readily. Vapors from liquefied gas are initially heavier than air and spread along ground. Some of these materials may react violently with water. Cylinders exposed to fire may vent and release toxic and/or corrosive gas through pressure relief devices. Containers may explode when heated. Ruptured cylinders may rocket. For UN1005: Anhydrous ammonia, at high concentrations in confined spaces, presents a flammability risk if a source of ignition is introduced. (ERG, 2016)

    Mixing of ammonia with several chemicals can cause severe fire hazards and/or explosions. Ammonia in container may explode in heat of fire. Incompatible with many materials including silver and gold salts, halogens, alkali metals, nitrogen trichloride, potassium chlorate, chromyl chloride, oxygen halides, acid vapors, azides, ethylene oxide, picric acid and many other chemicals. Mixing with other chemicals and water. Hazardous polymerization may not occur. (EPA, 1998)

    Excerpt from ERG Guide 154 [Substances - Toxic and/or Corrosive (Non-Combustible)]: Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.). Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated. For electric vehicles or equipment, ERG Guide 147 (lithium ion batteries) or ERG Guide 138 (sodium batteries) should also be consulted. (ERG, 2016)

    5.3 Special protective actions for fire-fighters

    10.2 Chemical stability

    Stable under recommended storage conditions.

    10.3 Possibility of hazardous reactions

    Not flammable.The gas is lighter than air.Ammonia gas is lighter than air. However, under certain conditions, when compressed liquified ammonia gas initially escapes a cylinder and comes into contact with moisture in the air it will form an ammonia fog. This fog is likeley to remain low to the ground, and could prevent ammonia gas from rising in the air.Dangerous concentrations of ammonia gas will occur quickly in enclosed or poorly ventilated spaces.Ammonia solutions react exothermically with acids to produce water and ammonium salts, Heating or treating with strong bases also causes evolution of gaseous ammonia. Ammonia can burn or explode if exposed to an intense source of ignition but can generally be treated as nonflammable. Readily combines with silver oxide, silver chloride, silver nitrate, silver azide or mercury to form explosive compounds. Forms explosive ammonium chlorate on contact with chlorates [Kirk-Othmer, 3rd ed., Vol. 2, 1978, p. 470]. Reacts violently or produces explosive products with fluorine, chlorine, bromine and iodine and bromine pentafluoride and chlorine trifluoride. Mixing of bleaching powder (hypochlorite solution) with ammonia solutions produces toxic/explosive ammonia trichloride vapors. May react violently with boron halides, ethylene oxide (polymerization), perchlorates and strong oxidizing agents (chromyl chloride, chromium trioxide, chromic acid, nitric acid, hydrogen peroxide, chlorates, fluorine, nitrogen oxide, liquid oxygen).

    • Toxicity to daphnia and other aquatic invertebrates: LC50; Species: Daphnia magna (water flea); Concentration: 24 mg/L for 48 hr /Conditions of bioassay not specified
    • Toxicity to algae: no data available
    • Toxicity to microorganisms: no data available

    12.2 Persistence and degradability

    AEROBIC: When ammonia appears in water under the normal conditions (aerobic), it is rapidly converted to nitrate by nitrification; the principal water contaminant normally being nitrate. The pH in water is increased by the presence of ammonia ion, in the form of hydroxide ions. ... Bacteria convert the ammonia to nitrate creating an oxygen demand (BOD) several days after the introduction of ammonia. The bacteria that oxidize ammonia to nitrate are largely of the genus Nitrosomonas; conversion of nitrite to nitrate is carried out primarily by the genus Nitrobacter. Temperature, oxygen supply, and pH of the water are factors in determining the rate of oxidation.

    12.3 Bioaccumulative potential

    Plants have a high affinity for gaseous ammonia when leaf stomata are open in daylight.

    12.4 Mobility in soil

    Ammonia is strongly adsorbed on soil, and on sediment particles and colloids in water. This adsorption results in high concentrations of sorbed ammonia in oxidized sediments. Under anoxic conditions, the adsorptive capacity of sediments is less, resulting in the release of ammonia to either the water column or an oxidized sediment layer above.
