Skin Sensitization: May cause mild to moderate irritation, possibly allergic responses
Eye Irritation: Vapors or particles cause pain, redness, tearing, and severe irritation
Inhalation: Dust or vapor exposure results in respiratory irritation, coughing, sore throat
Chronic Effects: Data insufficient; structurally related compounds show no evidence of carcinogenicity
Other Health Effects: Not classified as mutagenic or teratogenic, no known reproductive toxicity
Medical Conditions Aggravated by Exposure: Pre-existing dermatological or respiratory conditions
Ecotoxicity: Toxic to aquatic organisms at moderate to high concentrations, persistent due to hydrophobic chain
