13 Oxidizing liquids Classification not possible
-
-
- - It is an organic compound which does not contain fluorine or chlorine but contains oxygen, and the oxygen is chemically bonded to the element other than carbon or hydrogen (P). However, the classification is not possible due to no data.

P330

Based on a report of an LD50 value of 1.1 mg/kg for rats (ACGIH (7th, 2007), PIM G001 (1998)), it was classified in Category 1.
1 Acute toxicity (Dermal) Category 1


Danger

P270
P280
P310
P321

Based on reports of LD50 values of 2.4 mg/kg (male) for rats and 1.2 mg/kg for rabbits (ACGIH (7th, 2007), PATTY (5th, 2001)), it was classified in Category 1.
1 Acute toxicity (Inhalation: Gases) Not applicable
-
-
- - Liquid (GHS definition)
1 Acute toxicity (Inhalation: Vapours) Category 1

Based on a report of an LC50 value (4 hours) of 6.75 mg/m3 (0.569 ppm) for rats (ACGIH (7th, 2007), PATTY (5th, 2001)), it was classified in Category 1. Besides, since the LC50 value is lower than 90% of the saturated vapor concentration (19.7 ppm), the reference value in units of ppm was applied as a vapor without a mist.
1 Acute toxicity (Inhalation: Dusts and mists) Classification not possible
-
-
- - Classification not possible due to lack of data.
2 Skin corrosion/irritation Category 2


Warning
H315 P302+P352
P332+P313
P362+P364
P264
P280
P321
There is a description that irritation was caused by contact with skins (HSDB (Access on July 2014)). Therefore, it was classified in Category 2.
3 Serious eye damage/eye irritation Category 2


Warning
H319 P305+P351+P338
P337+P313
P264
P280
Based on the description that as a result of applying this substance (2 drops of 0.1%) to human eyes, pressures in the eyeball were felt and chemical burns on the lids developed (ACGIH (7th, 2007)), and irritation occurs in contact with eyes (HSDB (Access on July 2014)), it was classified in Category 2.
4 Respiratory sensitization Classification not possible
-
-
- - Classification not possible due to lack of data.
4 Skin sensitization Classification not possible
-
-
- - Classification not possible due to lack of data.
5 Germ cell mutagenicity Classification not possible
-
-
- - Classification not possible due to lack of data.
6 Carcinogenicity Classification not possible
-
-
- - Classification not possible due to lack of data.
7 Reproductive toxicity Classification not possible
-
-
- - Classification not possible due to lack of data.
8 Specific target organ toxicity - Single exposure Category 1 (nervous system)


Danger
H370 P308+P311
P260
P264
P270
P321
P405
P501
Plasma and red blood cell cholinesterase inhibition was observed in humans, and blurred vision, lightheadedness, giddiness, breathlessness, weakness, excessive salivation, vomiting, frequent urination/defecation, cramps, unconsciousness, depth perception disorder, miosis, cyanosis and death were reported in accident cases of workers, etc. (ACGIH (7th, 2007), HSDB (Access on August 2014)). In experimental animals, red blood cell, plasma and brain cholinesterase inhibition was reported in oral or dermal administration to rats, and this effect was observed within the guidance value range for Category 1 (ACGIH (7th, 2007), HSDB (Access on August 2014)).
Besides, PATTY adopted in the previous classification was not adopted because the description was not found.
From the above, it was classified in Category 1 (nervous system).
9 Specific target organ toxicity - Repeated exposure Category 1 (nervous system)


Danger
H372 P260
P264
P270
P314
P501
In a clinical study evaluating the use of this substance as a treatment for myasthenia gravis, in which this substance was administered orally or parenterally to 18 normal human subjects, a rapid depression of plasma and red blood cell cholinesterase activity occurred through the parenteral route, and a similar effect in oral administration was observed at approximately 4 times the dose in parenteral administration (ACGIH (7th, 2007)). From the above, it is clear that this substance also exhibits cholinesterase inhibition like other organophosphorus substances, and although there is no direct evidence from repeated exposure in humans to this substance, nervous system toxicities were considered to be related to cholinesterase inhibition even after a single exposure, so it can be predicted that nervous system toxicities will develop after repeated exposure in humans. Therefore, it was classified in Category 1 (nervous system).
10 Aspiration hazard Classification not possible
-
-
- - Classification not possible due to lack of data.
