Purity nitrogen

Material Safety Data Sheet / Material Safety Data Sheets MSDS first part nitrogen COMPOSITION / INFORMATION ?????????????????? pure ????????????? ???? □ mixture Chemical Name:? nitrogen (Nitrogen) Chemical formula: N2 Hazardous components: N2 ????????????????? ?????? Concentration:? 99.99 ?% second HAZARDS Risk category: 2.2 incombustible gas pathways: inhalation Health Hazards: Acute Potential Health Effects: Inhalation: Simple asphyxiant. Nitrogen is non-toxic gas, but it will displace oxygen in the air and cause suffocation. Hypoxia can cause serious injury or death. Eye contact: No adverse effects Skin contact: No adverse effects from exposure Information: pathways: inhalation TARGET ORGANS: No effect Results: suffocation symptoms: Exposure to oxygen levels below 19.5% in the air, can cause dizziness, fatigue, nausea, vomiting, excess salivation, unresponsiveness, loss of consciousness or even death. If containing 8-10% or less oxygen in the air, it will be without warning to loss of consciousness, loss of self-rescue and capabilities. A condition caused by excessive exposure to the deterioration: non-carcinogenic: Not NTP, OSHA and IARC listed as a carcinogen. Environmental hazards: No significant effect Explosion Hazards: Unusual Fire and Explosion Hazards: quickly discharge or severe heat or explosion when the gas cylinder in a fire environment. Most cylinders are designed to vent when the temperature rises. As the pressure increases within the heat effect cylinders, if pressure relief devices should fail to cause cylinder explosion. The third part of the emergency measures Skin contact: Remove sources of pollution, and take off the contaminated clothing as soon as possible, rinse with water for 15-20 minutes or more. Covering the injured area, and immediately taken to hospital and keep warm. Eye contact: Avoid rubbing the eyes or patients with eyes closed, carefully open the eyes of patients, 20-30 minutes rinse with water, as there irritation, repeated washing. Then covered his eyes with gauze, and immediately taken to hospital. Inhalation: If hypoxia personnel, must be moved to fresh air Ruoyi stop breathing, artificial respiration, if breathing is difficult, oxygen, and prompt medical attention. Ingestion: meaningless medical attention: When inhaled, consider giving oxygen. Part IV Special risks: an inert gas, is likely to cause suffocation. Hazardous combustion products: meaningless fighting methods and extinguishing agents: fire extinguishing agent itself Note: Special Fire Fighting Instructions: Nitrogen is a simple asphyxiant, if possible, remove nitrogen cylinders from fire or water cooling. Rescuers may need to use self-contained breathing apparatus. Unusual Fire and Explosion Hazards: quickly discharge or severe heat or explosion when the gas cylinder in a fire environment. Most cylinders are designed to vent when the temperature rises. As the pressure increases within the heat effect cylinders, if pressure relief devices should fail to cause cylinder explosion. Part V leakage Emergency treatment: Evacuate all personnel from affected area, the region strengthen ventilation, and monitor oxygen level. Use appropriate protective equipment (SCBA). If or leaks from the cylinder from the valve, call the gas company's emergency telephone number. If the leak is in user's system, close the cylinder valve and vent pressure before attempting repairs. Remedy: the security situation, to prevent the leakage if leakage from the cylinder body, unable to stanch the leak area to maintain adequate ventilation, and to monitor the oxygen concentration around and let it drain completely. Part VI Handling and Storage Handling Precautions: Be sure not to pull, roll or slide cylinders. Use a suitable handtruck to move the cylinder, do not try to grab the cylinder cover to picked it. Secure cylinders at all the process of using a fixed state. Use a pressure reducing regulator or separate control valve to safely discharge gas from cylinder. Use a check valve to prevent backflow. Do not heat the cylinder to increase the pressure and discharge amount. If user experiences any difficulty operating cylinder valve, discontinue use and contact supplier. Never insert an object (such as: wrench, screwdriver, pry bar, etc.) into valve cap. Otherwise it will damage the valve and cause a leak. Use an adjustable strap wrench to remove over-tight or rusted caps. It is with all common materials are compatible. Piping and equipment designed to meet the needs pressure. Special Requirements: To store and use compressed gas compressed in accordance with the provisions of the American Gas Association Safe Handling Manual CGA P-1 compressed gas cylinders in storage or local regulations may require the use of special equipment. NOTE: The user must be aware of the dangers caused by nitrogen concentration, especially in the limited space. OSHA compliance, especially 29CFR1910.146. Storage: in well-ventilated, safe and protected from the weather where stand straight storage, storage temperature high 125F (52C), and there should be no combustible materials away from heavily traveled areas and emergency exits in the storage area. There should be no salt or other corrosive material is present. Cylinders not used should be protected under the bonnet and valve seal intact. Empty bottles and full bottles stored separately. Avoid excessive inventory and storage time is too long. Use the FIFO system, maintain good records of Part VII storage Exposure controls / personal protection maximum allowable concentration: Not available monitoring methods: Not available Engineering controls: Provide good ventilation or exhaust to prevent accumulation of gas concentration is too high. Monitoring the oxygen content in the work area to ensure that not less than 19.5%. Respiratory protection: In general: do not. Emergency situations: when the oxygen content is less than 19.5% of the available self-contained breathing apparatus or positive pressure air line respirators with an escape mask and devices. Air purifying respirators will not function. Eye protection: Chemical safety goggles, face shield. Physical protection: transport should wear safety shoes. Hand protection: leather work gloves can be, no special requirements.
