2 | Skin corrosion/irritation | Category 2 |
Warning |
H315 | P302+P352 P332+P313 P362+P364 P264 P280 P321 |
Based on the description that this substance is very irritating to moist skin (ACGIH (7th, 2001)), the substance was classified in Category 2. Besides, it is classified as Class 8 in the United Nations Recommendations on the Transport of Dangerous Goods. The classification was changed with a revision of the GHS classification guidance for the Japanese Government. |

Danger |
H370 | P308+P311 P260 P264 P270 P321 P405 P501 |
This substance reacts with water to form calcium hydroxide. It is described that for humans, pulmonary edema and shock are caused by short exposure to a large amount of calcium hydroxide (PATTY (4th, 1993)). From the above, the substance was classified in Category 1 (respiratory organs). Besides, in the previous classification, this substance was classified in Category 2 (systemic toxicity, digestive system), based on the description in HSDB that when this substance is accidentally swallowed, the pulse and respiration become faster, the body temperature drops, glottic edema causes dyspnea and shock, and esophageal and gastric perforation occurs. However, this information cannot be found in current HSDB (Last Revision Date: September 4th, 2014), and it is thought that esophageal and gastric perforation was caused by the corrosive effects of this substance. Therefore, the classification was revised. |

9 | Specific target organ toxicity - Repeated exposure | Category 1 (respiratory organs) |
Danger |
H372 | P260 P264 P270 P314 P501 |
It is reported that inflammation of the respiratory passages and ulceration and perforation of the nasal septum are caused by inhalation of lime in humans (ACGIH (7th, 2001)). Therefore, the substance was classified in Category 1 (respiratory organs). | FY2016 | GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1)) |
10 | Aspiration hazard | Classification not possible |
- |
- | - | Classification not possible due to lack of data. Besides, in the previous classification, it was classified in Category 1 based on the description in HSDB that "aspiration pneumonia" was observed in humans. However, it was considered that this description was an error in the writing of the information in HSDB that "pneumonia" resulted from "inhalation" of calcium oxide dust in humans (HSDB (Access on May 2016)). |
