Ammonia solution, also known as ammonia water, ammonical liquors, ammonia liquors, aqua ammonia, aqueous ammonia, or (inaccurately) ammonia, is a solution of ammonia in water. It can be denoted by the symbols NH3(aq). It is sometimes thought of as a solution of ammonium hydroxide. Although the name ammonium hydroxide suggests an alkali with composition [NH4+][OH-], it is actually impossible to isolate samples of NH4OH. The ions NH4+ and OH- do not account for a significant fraction of the total amount of ammonia except in extremely dilute solutions.
Aqueous Ammonia (Liquor Ammonia) Ammonia in Water, commonly known as Aqua Ammonia renders it safe to handle and helps avoid the hazards that accompany use of Ammonia Gas by greatly reducing its vapour pressure. Also known as Ammoniacal Liquor, it is an inorganic chemical used as a liquid chemical in various industries like Rubber, Pharmaceuticals among others. Sometimes called Ammonium Hydroxide, the chemical formula is NH4OH with Un No. 2672 and CAS registry is 1336-21-6. Commonly manufactured with a concentration of about 25% w/w, Ammonia Solution is supplied in varying Packaging capacities ranging from 5 Lt. To 235 Lt. HMHDPE Plastic containers, 10 MT to 20 MT Tankers and 22 MT ISO Tankers.
AMMONIA SOLUTION: Quickly, on disturbance releases Ammonia Gas which has a pungent odour, is an irritant, and corrosive to skin, eye, respiratory tract and mucous membranes.
Nature of Hazards: Heating will cause pressure rise, severe risk of bursting. The vapor and mist has strongly irritating effects on eyes, skin and respiratory tract. The liquid causes severe burns to the body parts on extended contact. Spilled liquid quickly evaporates and spreads in atmosphere.
Protective Devices: Use Ammonia canister Mask or Self Contained Breathing Apparatus (SCBA) for respiratory protection or suitable respiratory protective devises, goggles giving complete protection to eyes, PVC or rubber gloves, boots, suits and hood for complete protection of body and Eye-wash bottle containing clean water.
Emergency Action: If possible move vehicle to open ground. Stop the engine. Mark roads and warn other road users. Keep public away from danger area. Keep the persons up-wind if possible or do not face the wind coming in from the direction of leak or spillage. Put on protective devices.
Spillage: If vapors drift towards populated area, warn inhabitants. Contain leaking liquid with sand or earth. If this is not practicable, use water spray to knock down the vapour.
Fire: Keep containers cool by spraying with water if exposed to fire.
First Aid: Remove contaminated clothing immediately and wash affected skin with plenty of water. If Ammonia vapours get in to eyes, wash eyes with plenty of water for at least 15 minutes. Seek medical treatment when anyone has symptoms apparently due to inhalation or contact with skin or eyes. Persons who have inhaled the gas must lie down and keep still. Keep patients warm. Do not apply artificial respiration if patient is breathing.
Additional Information: Do not mishandle Ammonia Drums/Jerrycans. Protect them from any source of heat as ammonia has a very high vapour pressure which rises rapidly with temperature. Drums/Jerrycans should not be laden above the height of truck body and no part of Drums/Jerrycans should project outside the truck body.
Liquefied Ammonia is supplied in steel containers of varying capacity ranging from 40 to 60 kg Cylinders, 400 kg Tonners, 6 to 15 MT Tankers and ISO Tanks. All of these packaging units with capability to withstand higher pressures are compliant with necessary statutory requirements of the Petroleum and Expl osives Safety Organization and the International Maritime Organization as applicable.
In an open and well ventilated area, Ammonia is generally not a fire hazard while in a closed and confined area Ammonia may be a fire hazard, especially if oil and other combustible materials are present. Galvanized surfaces, aluminum alloys, brass, bronze, copper, gold and silver gets corroded on exposure to Ammonia Gas.Anhydrous Ammonia Solution (Ammonium Hydroxide)
