Potassium chlorate

Flammability

Link to relevant study record(s)

Reference

Reference 1

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

Reference 2

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

Reference 3

Endpoint:

self-heating substances / mixtures

Data waiving:

study scientifically not necessary / other information available

Justification for data waiving:

other:

Reference 4

Endpoint:

flammable solids

Type of information:

experimental study

Adequacy of study:

key study

Study period:

September 2009

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Remarks:

Study performed according to international guideline. No deficiencies. Performed under internal quality management system.

Qualifier:

according to guideline

Guideline:

EU Method A.10 (Flammability (Solids))

Version / remarks:

Official Journal of the European Union no. L142, May 31,2008

Deviations:

no

GLP compliance:

no

Key result

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

Remarks:

no ignition and no propagation of combustion occurred

In the screening test the gas flame was applied for 2 minutes to one end of the substance train, but no ignition and no propagation of combustion occurred. Only melting took place of that part of the substance that was exposed to the flame. This means that the substance is not considered as highly flammable and that no further testing is required.

Interpretation of results:

non flammable

Conclusions:

3811-04-9, Potassium chlorate is NOT considered as a Flammable solid.

Description of key information

3811-04-9, Potassium chlorate is not considered as a Flammable solid.

Key value for chemical safety assessment

Flammability:

non flammable

Additional information

Potassium chlorate is non flammable.

In addition, it is not expected that potassium chlorate has pyrophoric or self-heating substance properties and reacts with water. It is very well soluble in water.

Justification for classification or non-classification

Based on the information indicated above, no classification is needed on flammability, pyrophoric properties, self-heating substance and reactivity with water.
