Ammonia gas is a compound that is made up of hydrogen and nitrogen by using the formula chemically NH3. It is a colorless gas that can be identified by its smell as it has an odor that is strong. Ammonia gas is commonly used for fertilizers and refrigerants however you'll likely be able to spot it before it is harmful to your health. The risk ammonia gas poses is dependent on the amount of gas present as well as the length of exposure you've had to endure. Read more here: https://www.blacklinesafety.com/solutions/gas-sensors/nh3
Gas Characteristics
Colorless
State of the gas
Compressed
Toxic
Flammable
Corrosive
Lighter than air
Water soluble
Explosive (at large concentrations and in tight spaces)
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 compost piles are located on mushroom farms release ammonia gas. Manure pits, as well as any enclosed or indoor areas where animals are kept from farms may be sources Ammonia gas.
Refrigeration System Ice skating rinks as well as factories for ice make use of liquid ammonia. In the event it spills out, it turns into an gas.
Fertilizers and Cleaners Liquid Ammonia is typically mixed together with other chemicals.
Some manufacturing procedures also make use of ammonia
There is a possibility to be exposed to ammonia using products for cleaning that contain ammonia
Other sources of occupational exposure include reflection mirrors' silvering creation of glue, tanning leather and around nitriding furnaces
Ammonia is created as an end-product of coal distillation as well as through the steam action on calcium cyanamide, and through the breakdown of nitrogenous substances
Ammonia is naturally found inside soybean (8,600 ppm) and in the seeds in the evening primrose (2,300-2,455 ppm) and lambsquarter as well as leaf tobacco (Duke 1992).
Ammonia leaks are rising due to the increasing usage of natural refrigerants over alternative fluorinated gases.

High Risk Scenarios
Ammonia levels are usually higher in colder than warmer ones.
In a closed area, ammonia could explode when the ignition source is there
If there are no accidental release of ammonia the chance of exposure to very high levels of ammonia is the highest in the time when space is restricted for entry
Technically speaking, when an employee is thrown off the edge of an opening, they are actually entering the enclosed area. when ammonia is present workers should be aware that confined spaces could pose a risk to their health.
In the event of a leak , or CSE process, it would be wrong to believe that the odor of ammonia is a sufficient warning to warn
