Hazard class | Classification |

Hazard statement | Precautionary statement | Rationale for the classification | |
---|---|---|---|---|---|---|
1 | Explosives | Not applicable | - | - | - | There are no chemical groups associated with explosive properties present in the molecule. |
2 | Flammable gases (including chemically unstable gases) | Not applicable | - | - | - | "Liquids" according to GHS definition. |
3 | Aerosols | Not applicable | - | - | - | Not an aerosol product. |
4 | Oxidizing gases | Not applicable | - | - | - | "Liquids" according to GHS definition. |
5 | Gases under pressure | Not applicable | - | - | - | "Liquids" according to GHS definition. |
6 | Flammable liquids | Category 4 |
H227 |
P370+P378 P403+P235 P210 P280 P501 |
A flash point of 86 degrees C [closed cup] (GESTIS (Access on Dec. 2010)) is > 60 degrees C and <= 93 degrees C, therefore, it corresponds to Category 4. | |
7 | Flammable solids | Not applicable | - | - | - | "Liquids" according to GHS definition. |
8 | Self-reactive substances and mixtures | Not applicable | - | - | - | Containing neither chemical groups related to explosibility nor those related to self-reactivity. |
9 | Pyrophoric liquids | Not classified | - | - | - | It is conceivable that it does not ignite at normal temperatures because an ignition temperature is not lower than 400 degrees C (HSDB (2010)). |
10 | Pyrophoric solids | Not applicable | - | - | - | "Liquids" according to GHS definition. |
11 | Self-heating substances and mixtures | Classification not possible | - | - | - | No established test method suitable for liquid substances. |
12 | Substances and mixtures which, in contact with water, emit flammable gases | Not classified | - | - | - | There is information that a compound that contains a semimetal (Si) reacts vigorously with water and produces hydrogen chloride (IMDG (2008)), therefore, it was classified as "Not classified" because flammable gasses are not emitted. |
13 | Oxidizing liquids | Classification not possible | - | - | - | An organic compound that contains chlorine which is chemically bonded to an element (Si) other than carbon, but there are no data. |
14 | Oxidizing solids | Not applicable | - | - | - | "Liquids" according to GHS definition. |
15 | Organic peroxides | Not applicable | - | - | - | An organic compound that does not contain -O-O- structure. |
16 | Corrosive to metals | Classification not possible | - | - | - | There is information that it is not suitable for a container due to highly corrosive to most metals (Hommel (1996)), but the classification was not possible due to no prescribed data. |

---|---|---|---|---|---|---|
1 | Acute toxicity (Oral) | Not classified | - | - | - | On the basis of an LD50 value of 2390 mg/kg for rats (HSDB (2010)), it was classified as "Not classified" in JIS classification (corresponding to Category 5 in UN GHS classification). |
1 | Acute toxicity (Dermal) | Category 4 |
H312 |
P302+P352 P280 P312 P322 P363 P501 |
On the basis of an LD50 value of 1166 mg/kg for rabbits (HSDB (2010)), it was classified in Category 4. | |
1 | Acute toxicity (Inhalation: Gases) | Not applicable | - | - | - | "Liquids" according to GHS definition. |
1 | Acute toxicity (Inhalation: Vapours) | Category 1 |
H330 |
P304+P340 P403+P233 P260 P271 P284 P310 P320 P405 P501 |
On the basis of an LC50 value of 0.33 mg/L/2h for mice (converted to a 4-hour equivalent: 0.23 mg/L (26.6 ppm)) (HSDB (2010)), it was classified in Category 1. Besides, a reference value of gasses was applied because the LC50 value (0.33 mg/L = 38.2 ppm) is lower than 90 % of the saturated vapour pressure concentration (561 ppm). |
|
1 | Acute toxicity (Inhalation: Dusts and mists) | Classification not possible | - | - | - | No data. |
2 | Skin corrosion/irritation | Category 1 |
H314 |
P301+P330+P331 P303+P361+P353 P305+P351+P338 P304+P340 P260 P264 P280 P310 P321 P363 P405 P501 |
It was classified in Category 1 base on a result as "highly corrosive" in a rabbit test (IUCLID (2000)) and a result indicating "corrosion" in another rabbit test (HSDB (2000)). | |
3 | Serious eye damage/eye irritation | Category 1 |
H318 |
P305+P351+P338 P280 P310 |
It was classified in Category 1 because a test using rabbits was rated 9 on a scale of 1 to 10 according to a degree of injury which was paid particular attention to the condition of corneas (HSDB (2010)), and another test using rabbits resulted in "highly corrosive" (IUCLID (2000)). | |
4 | Respiratory sensitization | Classification not possible | - | - | - | No data. |
4 | Skin sensitization | Classification not possible | - | - | - | No data. |
5 | Germ cell mutagenicity | Classification not possible | - | - | - | No data. |
6 | Carcinogenicity | Classification not possible | - | - | - | No data. |
7 | Reproductive toxicity | Classification not possible | - | - | - | No data. |
8 | Specific target organ toxicity - Single exposure | Category 2 (respiratory system) |
H371 |
P309+P311 P260 P264 P270 P405 P501 |
It is reported that mice exposed to low vapor concentrations showed breathlessness, cyanosis, and mucosal irritation as well as agitated motor activity and convulsions (HSDB (2010)), and the animals which died in the post-observation period showed edema in the brain and lung as well as degenerative effects in the liver, and distinct lung damage (HSDB (2010), GESTIS (Access on Dec. 2010)). An LC50 value of 0.23 mg/L/4h corresponds to Category 1 in accordance with the Guidance values, but it was classified in Category 2 (respiratory system) because data were from List 2 and that does not meet Decision Criteria 1b3). Besides, there are warnings that "breathing phenyl trichlorosilane can irritate the lungs causing coughing and/or shortness of breath," and "higher exposures can cause a build-up of fluid in the lungs (pulmonary edema), a medical emergency, with severe shortness of breath" (HSFS (2000)). |

9 | Specific target organ toxicity - Repeated exposure | Classification not possible | - | - | - | No data. |
10 | Aspiration hazard | Classification not possible | - | - | - | No data. |
