Application

Ammonium chloride is used in technical and machinery engineering, nonferrous-metals industry, chemical, timber and wood, electrical, medical and other industries.

Safety requirements

Ammonium chloride technical is fire and explosion safe with a level of toxicity — 3.

Packing

Ammonium chloride technical is usually packed in four-, five-, six-layer paper bags, paper composite bags and plastic bags.

It is allowed to pack the product in special soft disposable containers.

Transportation, storage

Ammonium chloride technical gets transported by all means of transport (except by air) but should be kept in covered vehicles. The product packed in special soft containers gets transported by train in open carriages without reloading on the way.

Ammonium chloride technical is usually stored in a closed warehouse protected from moisture. The area where the bags are placed, must be free of protruding or sharp objects which could puncture the bags.

It is allowed to store ammonium chloride packed in special soft containers outdoors.

Shelflife

1 year from a manufacturing date.

At the customers request in order to eliminate sticking the powder can be supplied treated by an anticonglomerating agent — a synthetic mixture of aliphatic amines C17-C21 0.2 kg per 1 tonne of ammonium chloride. The mass fraction of water-insoluble substances in this product increases by 0.02%.

Basic properties and hazards
Basic properties Granules of white colour with a shade of yellow and pink, no odor. It is soluble in water. The product gets transported in a solid condition.
Explosion and fire Fire-and explosion-proof. Non-flammable. Ammonia released in the production of ammonium chloride and mixed with air forms a flammable substance which might explode from a spark.
The risk to humans Harmful if in contact with skin and eyes. The product moderately irritates the human skin and mucous membranes of the eyes. In case of fire the product can cause burns.
During the production process of ammonium chloride a toxic substance gets released. It is called gaseous ammonia (danger level 4), that causes irritation of the upper respiratory tract, eyes, and mucous membranes of the nose at low concentration, and excites the central nervous system at high concentration.
The product with an anticonglomerating agent — a synthetic mixture of aliphatic amines — is non-explosive, toxic. The anticonglomerating agent refers to toxic compounds, and has local and general toxicity; it is able to penetrate the intact skin.
Individual protection means A military protective suit L-1 or L-2, in a kit with industrial gas masks with cartridges A and B. An uniform. Oil-resistant gloves, protective shoes.
In case of fire — fire resistant suit, in a kit with self-rescuers SPI-20.
When finished work the employers must have a shower.
Necessary steps in case of emergency
General Drive the carriage into a safe place. Isolate the zone of danger in the radius not less than 100 m. Do some adjustments to the distance after a comlete check of the level of pollution. Any outsiders should be asked to leave the zone of danger. Comply with fire safety measures. Do not smoke. Any injured person should receive the first aid.
Leakage, spilling and placer Report to TSSEN. Do not touch the spilled substance. Do not allow the dangerous substance to get into water supplies, basements, sewerage.
In case of fire
A person entering the zone of accident must wear protective clothing and breathing apparatus. Extinguish from a maximum range by water mist, air-mechanical foam.
Neutralization The deposit must be sprinkled with dry sand or other inert material. Call the experts for neutralization.
First aid Call the ambulance. Fresh air, relaxation, warm, clean clothes. The skin and mucous membranes should be washed with water.
