2 | Skin corrosion/irritation | Category 2 | Warning | H315: Causes skin irritation |
P302+P352: IF ON SKIN: Wash with plenty of soap and water. P332+P313: If skin irritation occurs: Get medical advice/attention. P264: Wash ... thoroughly after handling. P280: Wear protective gloves/protective clothing/eye protection/face protection. P321: Specific treatment (see ... on this label). P362: Take off contaminated clothing and wash before reuse. |
Based on descriptions that it has moderate stimulativeness on all body surface exposure including eyes and airways (ACGIH, 7th, 2001) and that it indicates moderate, severe, and a corrosive stimulation on human skin (IUCLID, 2000; HSDB, 2005; ICSC (J) 1997; SITTIG, 4th, 2002; and HSFS, 2005), it was classified as Category 2. | |

P305+P351+P338: IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing. P280: Wear protective gloves/protective clothing/eye protection/face protection. P310: Immediately call a POISON CENTER or doctor/physician. |
Based on the description that moderate, severe, and corrosive irritations are indicated to the eyes in humans (ACGIH, 7th, 2001; IUCLID, 2000; HSDB, 2005; ICSC (J) 1997; SITTIG, 4th, 2002; HSFS, 2005), and the deascription that corrosive irritations are indicated to the rabbits (IUCLID, 2000), it was set as Category 1. | |

8 | Specific target organ toxicity - Single exposure | Category 1 (respiratory system) | Danger | H370: Causes damage to organs (respiratory system) |
P307+P311: IF exposed: Call a POISON CENTER or doctor/physician. P260: Do not breathe dust/fume/gas/mist/vapours/spray. P264: Wash ... thoroughly after handling. P270: Do not eat, drink or smoke when using this product. P321: Specific treatment (see ... on this label). P405: Store locked up. P501: Dispose of contents/container to ... |
Classified into Category 1 (respiratory system) based on the descriptions (ACGIH, 7th, 2001; HSDB, 2005; ICSC (J), 1997; SITTIG, 4th, 2002; HSFS, 2005 ) that it stimulates human respiratory organ and respiratory tract to induce lung edema. | |
