Calcium nitrite

Flammability

Link to relevant study record(s)

Reference

Endpoint:

flammable solids

Type of information:

experimental study

Adequacy of study:

key study

Study period:

23 January - 9 March 2018 [several physical-chemical studies]

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Remarks:

Good quality study, conducted to GLP.

Qualifier:

according to guideline

Guideline:

EU Method A.10 (Flammability (Solids))

Deviations:

no

GLP compliance:

yes

Test procedure:

burning rate test: preliminary screening test

Remarks on result:

substance does not ignite and propagate combustion either by burning with flame or smouldering along 200 mm of the powder train within the 2 minutes test period

The test item melted, but did not burn. No further testing was deemed necessary.

Interpretation of results:

GHS criteria not met

Conclusions:

In a guideline GLP study, calcium nitrite (anhydrous) was found not to be highly flammable as it failed to ignite in a preliminary screening test.

Executive summary:

In an EU Method A.10 study, conducted according to GLP, calcium nitrite (anhydrous) was found not to be a highly flammable solid as it failed to ignite during a 2-minute period in a preliminary screening test.

Description of key information

In an EU Method A.10 study, conducted according to GLP, calcium nitrite (anhydrous) was found not to be a highly flammable solid as it failed to ignite during a 2-minute period in a preliminary screening test (Sydney, 2018).

Key value for chemical safety assessment

Flammability:

not classified

Justification for classification or non-classification

Based on the results of a reliable study (Sydney, 2018), anhydrous calcium nitrite does not require classification as a flammable solid according to EU CLP criteria (EC 1272/2008).
