What color is associated with ammonia?
Properties. Ammonia is a colourless gas with a characteristically pungent smell. It is lighter than air, its density being 0.589 times that of air.
What piping is used for ammonia?

How many designation sections are there to an ammonia pipe label?
In addition to five-part labels, each piece of equipment in an ammonia refrigeration system may also be labeled. This label consists of two sections: Name of the system component: Identify the equipment name with its abbreviation.
What color ammonia labels identify ammonia piping?
Orange
Orange pipe labels were to be used to identify toxic contents, which is more appropriate for ammonia. The IIAR adopted the use of orange labels for ammonia pipe marking to become more consistent with industry standards.
Does ammonia burn in air?
It is stated that ammonia does not burn in air because equation 1, despite being exothermic by nearly a megajoule, it is controlled by kinetics, not thermodynamics.
What happens when ammonia is heated?
It dissolves easily in water to form ammonium hydroxide solution which can cause irritation and burns. Ammonia gas is easily compressed and forms a clear, colorless liquid under pressure. Explanation: Ammonia is not highly flammable, but containers of ammonia may explode when exposed to high heat.
