8 | Specific target organ toxicity - Single exposure | Category 2 (respiratory system) |
Warning |
H371 | P308+P311 P260 P264 P270 P405 P501 |
Regarding the toxicity of this substance, there are the following reports: inhalation of the substance may cause a sore throat, coughing, a burning sensation, shortness of breath, headache, dizziness, nausea, and pulmonary edema (ICSC (J) (1997); inhalation of potassium sulfide may irritate the lungs causing coughing and shortness of breath; high exposure may cause pulmonary edema (HSFS (2001)); and inhalation of mist or dust may irritate the eyes, nose, or throat causing sneezing, coughing, or a sore throat; high exposure may cause pulmonary edema (SITTIG (2002)). In light of these reports, the substance was classified into Category 2 (respiratory system). Notes: This substance reacts with water to produce hydrogen sulfide. According to Japan's GHS classification, single inhalation exposure to hydrogen sulfide (ID998) in humans can cause nausea, headaches, delirium, a disturbed equilibrium, poor memory, neutrobehavioral changes, olfactory paralysis, loss of consciousness, tremors, convulsions, cardiac arrhythmias, increase in blood pressure (CICAD, 2003), loss of consciousness, and respiratory paralysis leading to death (IRIS, 2006). In rats that underwent single inhalation exposure to hydrogen sulfide at concentrations that are in the range of Category 1 guidance values, conditioned avoidance behavior was suppressed and histological damage to respiratory tract and olfactory mucosa was observed. And in mice underwent single inhalation exposure to hydrogen sulfide, mild irritation to nasal mucosa was noted (CICAD, 2003). Based on these reports, hydrogen sulfide is classified into Category 1 (central nervous system, cardiovascular system, and respiratory system). |

9 | Specific target organ toxicity - Repeated exposure | Classification not possible |
- |
- | - | Regarding the toxicity of the substance, there are following reports: very high exposure may cause an irregular heartbeat (HSFS (2001)); corrosive substances may cause lung disorders such as bronchitis (SITTIG (2002)); and prolonged exposure may cause sores or ulceration in the nose (SITTIG (2002)). Since these reports do not provide sufficient information, the substance was classified into the "Classification not possible" category. | FY2007 | GHS Classification Manual (10 Feb, 2006)/Technical Guidance Document on the GHS Classification (6 Dec, 2005) |
