PHYSICAL HAZARDS

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.	Flammable range with air is 1.7-11.7 vol%.

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 the description that death was not observed in the rat inhalation exposure test by 42000ppm 5-hour exposure (4-hour equivalent of 46957ppm) (ACGIH 7th, 2001).
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	-	-	-	-	No data available
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	-	-	-	-	Classification not possible due to lack of data
6	Carcinogenicity	Classification not possible	-	-	-	-	No data available
7	Reproductive toxicity	Classification not possible	-	-	-	-	No data available
8	Specific target organ toxicity - Single exposure	Category 3 （Narcotic effects, Respiratory tract irritation）		Warning	H336: May cause drowsiness or dizziness (narcotic effects, respiratory tract irritation) H335: May cause respiratory irritation (narcotic effects, respiratory tract irritation)	P304+P340: IF INHALED: Remove victim to fresh air and keep at rest in a position comfortable for breathing. P403+P233: Store in a well-ventilated place. Keep container tightly closed. P261: Avoid breathing dust/fume/gas/mist/vapours/spray. P271: Use only outdoors or in a well-ventilated area. P312: Call a POISON CENTER or doctor/physician if you feel unwell. P405: Store locked up. P501: Dispose of contents/container to ...	Because of a description in ACGIH (7th, 2001) referring to confirmation of anesthetic actions in an inhalation exposure test using rats, and there was no concrete case report, but descriptions in ICSC (J) (1997), HSFS (1999), and SITTIG (4th, 2002) referring to that respiratory tracts were stimulated, so it was judged as Category 3 (anesthetic actions, respiratory tracts stimulativeness).
9	Specific target organ toxicity - Repeated exposure	Classification not possible	-	-	-	-	Classification not possible due to lack of data
10	Aspiration hazard	Not applicable	-	-	-	-	Gas (GHS definition)
