Part 4: First aid measures Skin contact: Remove contaminated clothing and thoroughly wash the skin with soapy water and clean water. Eye contact: Lift the eyelids and rinse with flowing water or saline. Seek medical attention. Inhalation: Quickly move to a place with fresh air. Keep the airway clear. If there is difficulty breathing, administer oxygen. If breathing stops, perform artificial respiration immediately. Seek medical attention. Ingestion: Drink plenty of warm water and induce vomiting. Seek medical attention. Part 5: Fire-fighting measures. Hazardous characteristics: Can burn when exposed to an open flame. When moistened or exposed to high temperatures, it releases highly toxic ethynyl cyanide vapor. It is corrosive. Harmful combustion products: carbon monoxide, carbon dioxide, nitrogen oxides. Fire extinguishing method: Firefighters must wear oxygen respirators. Extinguishing agents: dry powder, carbon dioxide. The use of acid and alkali fire extinguishants is prohibited. Section 6: Emergency Response to Leaks – Emergency measures: Isolate the area contaminated by the leak and restrict access. Cut off the source of fire. It is recommended that emergency responders wear dust masks (full-face masks) and protective clothing. Minor leaks: Collect with a clean shovel and place in a dry, clean, covered container. Large-scale leakage: Collect, recycle, or transport to a waste disposal facility for disposal. Part 7: Handling, Disposal, and Storage. Handling precautions: Perform operations in a sealed environment with adequate local exhaust ventilation. Operators must receive specialized training and strictly adhere to the operating procedures. It is recommended that operators wear self-priming filter-type gas masks (half-masks), chemical safety goggles, polyethylene protective suits, and rubber gloves. Stay away from flames and heat sources; smoking is strictly prohibited in the workplace. Use explosion-proof ventilation systems and equipment. Avoid generating dust. Avoid contact with oxidizers, reducers, and acids. Handle with care during transportation to prevent damage to the packaging and containers. Equipped with fire-fighting equipment of appropriate types and quantities, as well as emergency response equipment for leaks. Empty containers may still contain harmful substances. Storage precautions: Store in a cool, well-ventilated warehouse. Keep away from flames and heat sources. The package is sealed. It should be stored separately from oxidizers, reducers, acids, and food chemicals; mixed storage is strictly prohibited. Equipped with fire-fighting equipment of the appropriate types and quantities. The storage area should be equipped with suitable materials to contain leaks. Part 8: Exposure Control/Personal Protection. Chinese MAC (mg/m3): No standard established. Former Soviet Union MAC (mg/m3): No standard established. TLVTN: No standard established. TLVWN: No standard established. Monitoring methods: Engineering controls: Strictly ensure sealing and provide adequate local exhaust ventilation. Provide safety showers and eye wash stations. Respiratory protection: When there is a possibility of exposure to toxins, a self-priming filter-type respirator (half-mask) should be worn. Self-contained breathing apparatus must be worn during emergency rescue or evacuation. Eye protection: Wear chemical safety goggles. Physical protection: Wear polyethylene protective clothing. Hand protection: Wear rubber gloves. Other protections: Smoking, eating, and drinking are prohibited at the work site. Once the work is done, clean thoroughly. Store the clothes contaminated with toxins separately and wash them before using them again. Maintain good hygiene* habits.
