Is aqueous ammonia a hazardous material?
Hazard statements : Harmful if inhaled. Causes severe skin burns and eye damage. May cause respiratory irritation. only outdoors or in a well-ventilated area.
Is aqueous ammonia explosive?
Nowadays, it is well recognized that ammonia can ignite and explode under certain conditions of con- tainment, within enclosures for instance, when its concentration in air is between 15 and 28% v/v. These are the most accepted concentrations limits.

What is the OSHA PEL for ammonia?
50 parts per million
The Permissible Exposure Limit for ammonia set by OSHA is 50 parts per million (ppm) averaged over an eight hour work day. This is the standard that must be met in every work place.
Is 19% aqueous ammonia flammable?
Ammonium hydroxide is very volatile and may release ammonia as a gas. Ammonia vapor, in concentrations of 16-25% volume by weight in air, is flammable, toxic by inhalation and corrosive.
Is aqueous ammonia an alkali?
In other words, if you look into a solution of aqueous ammonia, only a small fraction of the ammonia molecules have ionised to form ammonium ions and hydroxide ions. Most ammonia remains as simple molecules in the solution. Therefore, we say that ammonia is a weak alkali that undergoes partial ionisation.
Is aqueous ammonia soluble?
Ammonia solution

Is liquid ammonia flammable?
Ammonia gas is easily compressed and forms a clear liquid under pressure. Ammonia is not highly flammable, but containers of ammonia may explode when exposed to high heat.
What precautions should you take when working with ammonia?
Working Safely with Ammonia
- Wear personal protective equipment.
- Take hot work permitting precautions whenever hot work will be performed in areas where ammonia is present.
- Use proper ventilation.
- Store ammonia separately from incompatible chemicals, away from heat and ignition sources.
What kind of respirator do you use for ammonia?
3M NIOSH 42 CFR 84 approved combined P100 cartridge/filter for protection from ammonia and methylamine. These cartridges are compatible with 3M half facepiece and full facepiece respirators series 6000, 7000 and Ultimate-FX (FF-400).
Is aqueous ammonia a base?
However, ammonia is classified as a weak base which is a chemical compound that doesn’t completely break apart into ions in an aqueous solution. However, ammonia doesn’t fully convert into hydroxide and ammonium ions in a solution, which is why it is considered a weak base.
What is ammonia solution used for?
How is ammonia used? About 80% of the ammonia produced by industry is used in agriculture as fertilizer. Ammonia is also used as a refrigerant gas, for purification of water supplies, and in the manufacture of plastics, explosives, textiles, pesticides, dyes and other chemicals.
What is the limit of exposure to ammonia in a chamber?
5.2 Since the established permissible exposure limit for ammonia is 35 ppm as a 15 minute STEL, only persons wearing a positive pressure self-contained breathing apparatus or a positive pressure supplied air respirator shall be in the chamber. Normally only the person wearing the totally-encapsulating suit will be inside the chamber.
What is the first aid treatment for ammonia toxicity?
First Aid GENERAL INFORMATION: Initial treatment is primarily supportive of respiratory and cardiovascular function. ANTIDOTE: There is no antidote for ammonia toxicity. EYE: Immediately remove the patient/victim from the source of exposure. INGESTION: Immediately remove the patient/victim from the source of exposure.
What are the characteristics of agent Agent ammonia?
Agent Characteristics. The lowest level at which humans can detect the odor of ammonia (odor threshold) generally provides sufficient warning of exposure; however, persons with prolonged exposure to ammonia will lose their ability to detect the odor (olfactory fatigue). Ammonia commonly exists as part of a solution.
What are the effects of short term exposure to ammonia?
EFFECTS OF SHORT-TERM (LESS THAN 8-HOURS) EXPOSURE: Ammonia is a severe irritant of the eyes, respiratory tract, gastrointestinal (GI) tract, and skin. It reacts with the moisture in the moist linings of body passages and cavities (mucous membranes) to produce an alkaline solution, ammonium hydroxide.
