Do I need the green placard for agricultural ammonia test picture differences?
Anhydrous ammonia, the kind used as farm fertilizer, is commonly transported as a non-flammable gas, which uses the green Class 2.2 placard (UN 1005), often with an ANHYDROUS AMMONIA or INHALATION HAZARD marking. The right placard depends on the form and quantity, so always go by the shipping papers.
Anhydrous ammonia is usually a green Class 2.2 gas
Agricultural anhydrous ammonia (UN 1005) is typically classed as a non-flammable, non-toxic gas for transport, which is the green Class 2.2 placard. So a green placard is what you would usually expect to see on it.
Watch for the inhalation-hazard marking
Ammonia is also toxic to breathe, so it often carries an additional INHALATION HAZARD or ANHYDROUS AMMONIA marking alongside the green placard. That extra wording is a warning on top of the class, not a different class.
Go by the shipping papers
The exact placard depends on the form, concentration, and quantity, and whether placarding is required depends on the amount. Confirm the correct placard against the shipping papers, the Emergency Response Guidebook, and your official manual rather than assuming.
