Description of key information

Anhydrous ammonia is a flammable gas

Key value for chemical safety assessment

Flammability:
flammable

Additional information

Anhydrous ammonia was found to be flammable, with a lower explosion limit of 16% and an upper explosion limit of 25%.

Aqueous ammonia is considered non-flammable.

Justification for classification or non-classification

Anhydrous ammonia is listed on Annex I of Directive 67/548/EEC with classification as (R10) 'Flammable' corresponding to Flam. Gas 2 (H221). This classification is consistent with the data available: no change is proposed.


Aqueous ammonia is considered non-flammable.
