NH3

Ammonia gas is an element that is made up of nitrogen and hydrogen, by using the formula chemically NH3. It is a colourless gas that can be identified by its smell as it has an intense smell. Ammonia gas is used in the production of fertilizers and refrigerants however you're likely to detect it before it causes harm to your health. The risk ammonia gas has is dependent on the amount of gas present and the duration of exposure you've endured. 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 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 release ammonia gas. Manure pits, as as any enclosed or indoor space where animals from farms are kept may be sources Ammonia gas.

Refrigeration System Ice skating rinks as well as manufacturing facilities to make ice utilize liquid ammonia. In the event it spills, it turns into an gas.

Fertilizers and Cleaners Liquid Ammonia is usually mixed with a variety of other chemicals.

Some manufacturing procedures also utilize ammonia

It is possible to be exposed to ammonia using products for cleaning that contain ammonia

Other occupational exposure sources are reflection mirrors' silvering the production of glue, tanning leather and around nitriding furnaces

Ammonia is produced as an end-product of coal distillation as well as by the steam action on calcium cyanamide as well as through the decomposition of nitrogenous substances

Ammonia naturally is found naturally in soybean (8,600 ppm) and in the seeds of the evening primrose (2,300-2,455 ppm) and lambsquarter and the leaves of tobacco (Duke 1992).

The leaks of ammonia are growing because of the increased use of natural refrigerants in preference to alternative fluorinated gases.

High Risk Scenarios

Ammonia levels are typically higher in colder than warmer ones.

In a closed area, ammonia could explode when the ignition source is there

In the absence of accidental releases of ammonia the chance of exposure to very high levels of ammonia is the highest in restricted space entry

Technically speaking an employee is thrown off the edge of an opening, they are 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 instance of a leak or CSE procedure It is a mistake to think that the odor of ammonia is a sufficient warning to alert
