Pyridine,2,4-dimethyl- - Safety

Open Data Verified Data

health hazards: inhalation, ingestion, percutaneous absorption. Health hazards: harmful to the body after inhalation, oral or skin absorption. It is strongly irritating to the eyes. After contact can cause Cough, chest pain, Dyspnea, gastrointestinal dysfunction.
toxicological data and environmental behavior toxicity: moderate toxicity. Acute toxicity: LD50 400 ~ 800mg/kg (rats by mouth). Hazard characteristics: flammable, in case of high heat, open fire or contact with oxidant, there is a risk of combustion explosion. Toxic nitrogen oxide smoke is released by thermal decomposition. Combustion (decomposition) products: carbon monoxide, carbon dioxide, nitrogen oxides.
Protection Measure respiratory system protection: filter gas mask (half mask) should be worn when possible contact with its vapor. In case of emergency rescue or evacuation, it is recommended to wear an isolated respirator. Eye protection: wear chemical safety glasses. Body Protection: wear adhesive tape to prevent
poison coat. Hand Protection: wear rubber gloves. Other: no smoking at work site. After work, take a shower and change clothes. Pre-employment and regular medical examinations were carried out. Maintain good hygiene practices.
first aid measures skin contact: remove contaminated clothing and rinse the skin thoroughly with soap and water. Eye contact: lift the eyelids and rinse thoroughly with plenty of running water or saline for at least 15 min. The patient visited hospital. Inhalation: rapid departure from the scene to fresh air. Keep airway unobstructed. Such as Dyspnea, to the delivery of oxygen. If breathing stops, perform artificial respiration immediately. The patient visited hospital. Ingestion: drink enough warm water to induce vomiting.
