Section 3: Hazards Identification

Potential Acute Health Effects:

Very hazardous in case of skin contact (irritant), of eye contact (irritant), of ingestion, . Hazardous in case of skin

contact (corrosive), of eye contact (corrosive). Liquid or spray mist may produce tissue damage particularly on

mucous membranes of eyes, mouth and respiratory tract. Skin contact may produce burns. Inhalation of the

spray mist may produce severe irritation of respiratory tract, characterized by coughing, choking, or shortness of

breath. Severe over-exposure can result in death. Inflammation of the eye is characterized by redness, watering,

and itching. Skin inflammation is characterized by itching, scaling, reddening, or, occasionally, blistering.

Potential Chronic Health Effects:


MUTAGENIC EFFECTS: Mutagenic for bacteria and/or yeast. [Ammonia, anhydrous].



The substance may be toxic to mucous membranes, skin, eyes.

Repeated or prolonged exposure to the substance can produce target organs damage. Repeated or prolonged

contact with spray mist may produce chronic eye irritation and severe skin irritation. Repeated or prolonged

exposure to spray mist may produce respiratory tract irritation leading to frequent attacks of bronchial infection.

Repeated exposure to a highly toxic material may produce general deterioration of health by an accumulation in

one or many human organs.


Section 4: First Aid Measures

Eye Contact:

Check for and remove any contact lenses. Immediately flush eyes with running water for at least 15 minutes,

keeping eyelids open. Cold water may be used. Get medical attention immediately. Finish by rinsing thoroughly

with running water to avoid a possible infection.

Skin Contact:

In case of contact, immediately flush skin with plenty of water for at least 15 minutes while removing contaminated

clothing and shoes. Cover the irritated skin with an emollient. Cold water may be used.Wash clothing before

reuse. Thoroughly clean shoes before reuse. Get medical attention immediately.

Serious Skin Contact:

Wash with a disinfectant soap and cover the contaminated skin with an anti-bacterial cream. Seek immediate

medical attention.


If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get

medical attention immediately.

Serious Inhalation:

Evacuate the victim to a safe area as soon as possible. Loosen tight clothing such as a collar, tie, belt or

waistband. If breathing is difficult, administer oxygen. If the victim is not breathing, perform mouth-to-mouth

resuscitation. WARNING: It may be hazardous to the person providing aid to give mouth-to-mouth resuscitation

when the inhaled material is toxic, infectious or corrosive. Seek immediate medical attention.


Do NOT induce vomiting unless directed to do so by medical personnel. Never give anything by mouth to an

unconscious person. If large quantities of this material are swallowed, call a physician immediately. Loosen tight

clothing such as a collar, tie, belt or waistband.

Special Remarks on Explosion Hazards:

A sudden increase in temperature and pressure preceded a violent explosion when heating

1-chloro-2,4-dinitrobenzene and ammonia in a direct fired autoclave.

Reaction with liquid ammonia and chlorine azide gives an explosive yellow liquid.

Liquid ammonia + 1,2 dichloroethane may explode.

Passing ammonia gas over magnesium perchlorate dessicant causes intensive drying of ammonia gas which

leads to an exotherm, followed by a violent explosion.

Ammonia is capable of reacting with some heavy metal compounds (gold, silver, mercury) to produce materials,

some of uncertain constitution, whic may explode violently when dry.

Action of ammonia or ammonium salts on gold (III) chloride, oxide or other salts under a variety of conditions gives

explosive or "fulminating" gold.

Halogens or interhalogens + ammonia either reacts violently or produces explosive products.

Ammonia + nitrogen trichloride produces endothermic and explosive nitrogen trichloride.

Reaction of ammonia + selenium difluoride dioxide is violent and many of the products and derivatives are both

shock and heat sensitive explosives. These include ammonium, potasssium silver and thallium salts of the

"triselenimidate" ion.

Violent explosions with ammonia + nitrogen oxide can occur in ammonia synthesis gas units.

Liquid ammonia + solid dinitrogen tetraoxide reacts explosively.

Oxygen + Platinium: oxidation of ammonia to nitric acid over platinium catalysts, substituion of oxygen for air

causes fairly vigorous explosions.

Thiocarbonyl azid thiocyanate reacts explosively with ammonia gas.

Thiotrithiazyl chloride will rapidly absorb ammonia gas and then explode.

Tetramethylammonium amide decomposes explosively at ambient temp. in presence of ammonia.

Liquid ammonia + tellurium tetrachloride at -15 C forms tellurium nitride which explodes at 200 C.

Ammonia + tellurium tetrabromide gives a mixture of tritellurium tetramitride and tellulrium bromide nitride, which

explodes on heating.

Liquid ammonia + ethylene oxide causes violent polymerization and a vapor cloud explosion.

Ammonia + picric acid forms explosive salts.

(Ammonia, anhydrous)

Ammonium Hydroxide Forms explosive compounds with many heavy metals such as silver, lead, zinc and their

halide salts.

It can form shock sensitive compounds with halogens, mercury oxide, and siliver oxide.


Section 6: Accidental Release Measures
