Ammonia gas is an element made up of nitrogen and hydrogen, by using the formula chemically NH3. It is a colourless gas that can be identified by its smell since it has a strong smell. Ammonia gas is used for fertilizers and refrigerants however you're likely to detect it prior to it becoming harmful to your health. The risk ammonia gas has is dependent on the amount of gas present and the amount of time exposure you've had to endure. Read more here: https://www.blacklinesafety.com/solutions/gas-sensors/nh3
State of the gas
Lighter than air
Explosive (at high concentrations and in tight space)
Pungent, suffocating odor
Can decompose at high temperatures forming very flammable hydrogen gas
OTHER NAMES: Anhydrous ammonia, ammonia, azane, hydrogen nitride
Industrial NH3 hazards
farms: The compost piles that are located on mushroom farms emit ammonia gases. Manure pits, as well being any enclosed or indoor areas where animals from farms are kept could be a source Ammonia gas.
Refrigeration System: Ice skating rinks as well as manufacturing facilities for ice use liquid ammonia. In the event it spills out, it turns into an gas.
Liquid ammonia is a fertilizer and cleaner that is typically mixed together with other chemicals.
A few manufacturing methods use ammonia
There is a possibility to be exposed to ammonia by using products for cleaning that contain ammonia
Other sources of occupational exposure are reflection mirrors' silvering production of glue, tanning leather and around nitriding furnaces.
Ammonia is produced as an end-product of coal distillation and by the steam action on calcium cyanamide as well as through the decomposition of nitrogenous compounds
Ammonia naturally occurs within soybean (8,600 ppm) and the seeds of the evening primrose (2,300-2,455 ppm) as well as lambsquarter and leaf tobacco (Duke 1992).
Ammonia leaks are rising due to the growing use of natural refrigerants over fluorinated gas alternatives.

High Risk Scenarios
Ammonia levels are usually higher in colder than warmer ones.
In a closed space ammonia can explode if the ignition source is in place
In the absence of accidental releases of ammonia the risk for exposure to extremely high levels of ammonia is greatest during the period of restricted space entry
Technically speaking an employee does not fall off the surface of an opening, they is actually entering the enclosed area. If ammonia is present, workers should be aware that confined spaces could pose a risk for their health.
In the case of a leak , or CSE procedure It is not true that the ammonia odor will be enough to warn
