Seek medical attention if you feel unwell. In case of eye contact: Lift the eyelid and rinse with running water or saline for at least 15 minutes. Seek medical attention if you feel unwell, If inhaled: Remove the person to fresh air and keep comfortable for breathing. If breathing is difficult, give oxygen. Do cardiopulmonary resuscitation if respiratory arrest and asystole, consult a physician, 5 | Fire-fighting Measures Dangerous characteristic: It can cause or promote the combustion of other ‘materials more than air. In case of high heat, the internal pressure of the container will increase and there is a danger of cracking and explosion, Special hazards arising from the substance: Nitrogen oxides, Suitable extinguishing media: This product is non-flammable. Please choose the appropriate fire extinguishing medium according to the cause of fire, Special protective equipment for fire-fighters: Wear antigas mask and personnel protective clothes for fire-fighting and do it at upwind direction, Spray water to ccool the container and cut off the gas source, Move the container from the fire scene to an open place as much as possible. 6 | Accidental Release Measures Personal precautions: Cut off the source of leakage as much as possible. The warning zone shall be delineated according to the affected area of gas diffusion, and unrelated personnel shall be evacuated from the crosswind and upwind direction to the safe zone and be isolated, It is recommended that emergency personnel wear positive pressure self-contained breathing apparatus. Environmental precautions: Prevent further leakage or spillage if safe to do so, Methods and materials for containment and cleaning up: Cut off the source of leakage as much as possible, and cover the sewers and other places near the leakage point with industrial coatings or adsorbents/absorbents to prevent gas from entering. If possible, send the leaking air to an open area with an explosion-proof exhaust fan or install an appropriate nozzle to bum it. The leaking container must be properly handled. 7 | Handling and storage Safe handling: Airtight operation, full exhaust. Operators must undergo special ‘raining and strictly abide by operating procedures. Operators wear personal protective equipment. Keep away from fire and heat sources, and smoking is strictly prohibited in the workplace. Use explosion-proof ventilation systems and ‘equipment. Prevent gas from leaking into the workplace air. Avoid contact with flammable. When handling, load and unload lightly. Lightly load and unload during transportation to prevent damage to cylinders and accessories. Equipped with corresponding types and quantities of fire-fighting equipment and leakage ‘emergency treatment equipment. Conditions for safe storage, including incompatibility: Store in a cool, dry, and well-ventilated warehouse. Keep away fiom fire, heat, and sunlight. Keep theProduct Name: Nittous oxide Supplier: Ganzhow Xingye Chemical Industry Co. Lig SAFETY DATA SHEET (SDS) Date Prepared: 13-04-2021, Page 3 of container tightly closed. It should be stored separately from flammable and avoid mixed storage. Use explosion-proof lighting and ventilation facilities. It is forbidden to use mechanical equipment and tools that easily generate sparks. The storage area should be equipped with leakage emergency treatment equipment. Exposure Controls / Personal Protection Control parameter (such as the occupation exposure limits or biological exposure limit): No data available, Appropriate engineering controls: Strictly closed, provide adequate full ventilation system. Personal protective measures: Respiratory protection: If the concentration in the air is out of limits, must ‘wear all-cover filtering rebreather. Self-contained breathing apparatus are for emergency rescue or evacuation. Eye protection: Wear Chemical safety glasses. Body protective: Wear protective clothing. Hand protection: Wear protective gloves. Other protection: No smoking, no taking food and water at workplace. ‘Thoroughly wash after work. Work clothes should not take to non-work area, Disposing contaminated clothing individually, wash them every time after use, pay attention to personal hygiene.
