Hazard class Classification Symbol Signal word Hazard statement Precautionary statement Rationale for the classification
1 Explosives Not applicable - - - - Gas (GHS definition)
2 Flammable gases (including chemically unstable gases) Category 1 Danger H220: Extremely flammable gas P210: Keep away from heat/sparks/open flames/hot surfaces. - No smoking.
P377: Leaking gas fire: Do not extinguish, unless leak can be stopped safely.
P381: Eliminate all ignition sources if safe to do so.
P403: Store in a well-ventilated place.
Ignitable when in a mixture of 13% or less by volume in air. UNRTDG Class: 2.1
3 Aerosols Not applicable - - - - Not aerosol products
4 Oxidizing gases Not classified - - - - UNRTDG Class: 2.1
5 Gases under pressure Compressed gas or Refrigerated liquefied gas Warning H281: Contains refrigerated gas; may cause cryogenic burns or injury
H280: Contains gas under pressure; may explode if heated
P410+P403: Protect from sunlight. Store in a well-ventilated place.
P282: Wear cold insulating gloves/face shield/eye protection.
P315: Get immediate medical advice/attention.
P336: Thaw frosted parts with lukewarm water. Do not rub affected area.
According to its physical state when packed, classified in; Compressed gas: entirely gaseous at -50degC or critical temp <-50degC or, Refrigerated liquefied gas: partially liquid because of its low temperature
6 Flammable liquids Not applicable - - - - Gas (GHS definition)
7 Flammable solids Not applicable - - - - Gas (GHS definition)
8 Self-reactive substances and mixtures Not applicable - - - - Gas (GHS definition)
9 Pyrophoric liquids Not applicable - - - - Gas (GHS definition)
10 Pyrophoric solids Not applicable - - - - Gas (GHS definition)

12 Substances and mixtures which, in contact with water, emit flammable gases Not applicable - - - - Gas (GHS definition)
13 Oxidizing liquids Not applicable - - - - Gas (GHS definition)
14 Oxidizing solids Not applicable - - - - Gas (GHS definition)
15 Organic peroxides Not applicable - - - - Gas (GHS definition)
16 Corrosive to metals Not classified - - - - UNRTDG Class: 2.1

HEALTH HAZARDS
Hazard class Classification Symbol Signal word Hazard statement Precautionary statement Rationale for the classification
1 Acute toxicity (Oral) Not applicable - - - - Gas (GHS definition)
1 Acute toxicity (Dermal) Not applicable - - - - Gas (GHS definition)
1 Acute toxicity (Inhalation: Gases) Not classified - - - - It was considered as the outside of Category based on rat LC50 (1 hour): >15000ppm (IUCLID, 2000) (4-hour equivalent >7500ppm), .
1 Acute toxicity (Inhalation: Vapours) Not applicable - - - - Gas (GHS definition)
1 Acute toxicity (Inhalation: Dusts and mists) Not applicable - - - - Gas (GHS definition)
2 Skin corrosion/irritation Classification not possible - - - - No data available
3 Serious eye damage/eye irritation Classification not possible - - - - Although it was indicated that the toxic effects to an eye was not known by HSDB (2005), there being no data which negates hazard clearly in Priority1. So it cannot classify.
4 Respiratory sensitization Classification not possible - - - - No data available
4 Skin sensitization Classification not possible - - - - No data available
5 Germ cell mutagenicity Classification not possible - - - - No data available
6 Carcinogenicity Classification not possible - - - - No data available
7 Reproductive toxicity Classification not possible - - - - No data available
8 Specific target organ toxicity - Single exposure Classification not possible - - - - No data available.
9 Specific target organ toxicity - Repeated exposure Classification not possible - - - - No data available
10 Aspiration hazard Not applicable - - - - Gas (GHS definition)

ENVIRONMENTAL HAZARDS
Hazard class Classification Symbol Signal word Hazard statement Precautionary statement Rationale for the classification
11 Hazardous to the aquatic environment (Acute) Classification not possible - - - - There is no data to classify. (Since it is a gaseous substance which does not dissolve into water easily due to ordinary temperatures, the test is not carried out.)
11 Hazardous to the aquatic environment (Long-term) Classification not possible - - - - No data available. (Since it is a gaseous substance which does not easily dissolve into water in the ordinary temperature, the test has not been carried out.)
