Flammability
Administrative data
Link to relevant study record(s)
- Endpoint:
- substances / mixtures which in contact with water emit flammable gases
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because the experience in production or handling shows that the substance does not react with water, e.g. the substance is manufactured with water or washed with water
- Justification for type of information:
- //It is scientifically not necessary to conduct the study because none of the constituens in the substance has molecules containing metals or metalloids. Experience in handling shows that the product does not react with water. The substance is not flammable in contact with water.
In accordance with UN Manual of Tests and Criteria* Appendix 6-Screening procedures-Section 5.3 Substances which in contact with water may react to emit flammable gases (Division 4.3), the classification procedure for substances which in contact with water may react to emit flammable gases does not need to be applied.
*ST/SG/AC.10/11/Rev.6 (Recommendations on the Transport of Dangerous Goods- Manual of Tests and Criteria) - Endpoint:
- pyrophoric solids
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because the substance is known to be stable in contact with air at room temperature for prolonged periods of time (days) and hence, the classification procedure does not need to be applied
- Endpoint:
- flammable solids
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:

- Endpoint:
- self-heating substances / mixtures

Description of key information
Based on molecular structure and/or experience in handling, it was concluded that ammonium dihydrogenorthophosphate is not flammable when coming into contact with an ignition source, water or air.
Key value for chemical safety assessment
- Flammability:
- not classified
Additional information
Justification for classification or non-classification
Based on the available data, no classification according to CLP Regulation (EC) No 1272/2008 for the following hazards:
- Flammable solids
- Pyrophoric solids
- Self-heating substances
- Substances which in contact with water emits flammable gases
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
