N2 is also harmful How to protect against it ?
Nitrogen, under normal conditions, is a colorless, tasteless, odorless gas and is usually non-toxic. But when nitrogen levels in the environment rise and oxygen levels fall, dizziness and, in severe cases, suffocation and even death can occur. Let's understand the harm and protection of nitrogen, so as to avoid the harm of nitrogen.
Nitrogen makes up 78% of the atmosphere because it is inert and cannot be used as a fuel booster or to react directly with other substances at room temperature. When the nitrogen level in the environment increases and the oxygen level drops to 19 percent, dizziness often results. As the oxygen ratio continues to decline, it will cause simple asphyxia. Its main expression is airframe is anoxic, appear giddy, have a headache, exhale difficult, hurried, heartbeat is quickened, pulse is weak and fast, spirit absentmindedly uneasy, whole body is weak, muscle coordinated movement is maladjusted. If placed in a device or container fully filled with nitrogen, the person will immediately faint and suffocate until death. In normal chemical production, nitrogen is often used to empty the combustible gas in the pipeline. Because nitrogen is colorless and odorless, the low-oxygen environment caused by nitrogen purge is often ignored by workers and even grass-roots managers.
Nitrogen gas packing
Preventive measures: identify the risk of nitrogen. Places with high concentration of nitrogen must be clearly marked and warned. All staff and temporary workers should strengthen the knowledge of entering the restricted space education and exercise, examination can be employed after passing.
