Administrative data
Link to relevant study record(s)
- Endpoint:
- oxidising 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:
- UN Manual of Tests and Criteria: Test O.1 (Test for oxidizing solids)
- Deviations:
- no
- GLP compliance:
- yes
- Contact with:
- powdered cellulose
- Sample tested:
- 4:1 sample-to-cellulose ratio
- Parameter:
- mean burning time
- Result:
- 147.6 s
- Sample tested:
- 1:1 sample-to-cellulose ratio
- Parameter:
- mean burning time
- Result:
- 139.8 s
- Sample tested:
- reference: 3:7 mixture potassium bromate + cellulose
- Parameter:
- mean burning time
- Result:
- 96.6 s
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- In a guideline GLP study, calcium nitrite (anhydrous) was found not to be classified as Division 5.1 according to UN Test O.1 (non-oxidising solid).
- Executive summary:
In an UN Test O.1 study, conducted according to GLP, calcium nitrite (anhydrous) did not reduce the burning time of cellulose (4:1 and 1:1 w/w sample-to-cellulose ratios) relative to that of the reference formulation (3:7 w/w mixture of potassium bromate and cellulose). As such, it was found not to be classified as Division 5.1 according to UN Test O.1 (non-oxidising solid).
- Endpoint:
- oxidising liquids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- No data
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study without detailed documentation
- Qualifier:
- according to guideline
- Guideline:
- UN Manual of Tests and Criteria: Test O.2 (Test for oxidizing liquids)
- Deviations:
- not specified
- Remarks:
- limited documentation of the test method was provided in the summary report
- GLP compliance:
- not specified
- Contact with:
- other: no data
- Sample tested:
- test mixture (not specified)
- Parameter:
- other: mean maximum pressure rise in 1 minute
- Result:
- 9.2 other: PSI [63.4 kPa]
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- In a guideline study, calcium nitrite (hydrate) was found not to be a liquid oxidiser.
- Executive summary:
In a UN Test O.2 study (summary report), calcium nitrite (hydrate) induced a mean maximum pressure rise of only around 63.4 kPa (9.2 PSI) in 1 minute. As such, it did not meet the criteria of a liquid oxidiser as defined by the test specification.
Referenceopen allclose all
Individual run burn times were 152, 143, 156, 142 and 145 seconds for the 4:1 w/w test item:cellulose mixture, 134, 144, 148, 140 and 133 seconds for the 1:1 w/w test item:cellulose mixture, and 99, 101, 92, 96 and 95 for the 3:7 w/w mixture of potassium bromate and cellulose.
The burning times for both the 4:1 and 1:1 w/w test item:cellulose mixtures were greater than that of the 3:7 w/w mixture of potassium bromate and cellulose. As such, the test item is not classified as Division 5.1 according to UN Test O.1.
For the 5 replicates, the maximum pressure rise was 6, 6, 3, 22 and 9 in a time of 1 minute.
Description of key information
In an UN Test O.1 study, conducted according to GLP, calcium nitrite (anhydrous) did not reduce the burning time of cellulose (4:1 and 1:1 w/w sample-to-cellulose ratios) relative to that of the reference formulation (3:7 w/w mixture of potassium bromate and cellulose). As such, it was found not to be classified as Division 5.1 according to UN Test O.1 (non-oxidising solid) (Sydney, 2018).
In a UN Test O.2 study (summary report), calcium nitrite (hydrate) induced a mean maximum pressure rise of only around 63.4 kPa (9.2 PSI) in 1 minute. As such, it did not meet the criteria of a liquid oxidiser as defined by the test specification (Mendoza and Hanson, 1995).
Key value for chemical safety assessment
- Oxidising properties:
- non oxidising
Additional information
Justification for classification or non-classification
Based on the results of the reliable studies (Mendoza and Hanson, 1995; Sydney, 2018), calcium nitrite does not require classification as an oxidising solid or liquid according to EU CLP criteria (EC 1272/2008).
