What harm does breathing nitrogen have on the body?

Nitrogen is also widely used in our lives. If you accidentally inhale nitrogen, it will cause considerable harm to the body. Sometimes the patient's life may even be in danger. Therefore, we should pay attention to preventing the inhalation of nitrogen in normal times. For example, if you need to come into contact with nitrogen, you should take protective measures. Today, let us specifically understand the harm of inhaling nitrogen to the body.

This product is a colorless and odorless gas with inactive chemical properties and is non-flammable. It can react directly with lithium at room temperature and directly combine with magnesium, calcium, strontium, barium, oxygen and hydrogen when hot. It is slightly soluble in water and ethanol. This product is used to synthesize ammonia, make nitric acid, cyanide, explosives, etc. As an inert gas, it can be used to fill light bulbs and pyrometers. It is also used as a material protective agent and refrigerant.

Harm to the human body

This product enters the human body through inhalation. Excessive nitrogen content in the air causes the partial pressure of inhaled oxygen to drop, causing suffocation due to lack of oxygen. When the inhaled nitrogen concentration is not too high, the patient initially feels chest tightness, shortness of breath, weakness; followed by restlessness, extreme excitement, running around, shouting, dazed look, and unstable gait. This is called nitrogen intoxication, and the patient may enter a state of drowsiness or coma. If high concentrations are inhaled, the patient may quickly become comatose or die from respiratory and cardiac arrest.

When divers dive deep, they may experience nitrogen narcosis. If they switch too quickly from a high-pressure environment to a normal-pressure environment, nitrogen bubbles will form in the body, compressing the nerves and blood vessels or causing microvascular blockage, resulting in decompression sickness.

First aid measures

After inhaling this product, quickly leave the scene to a place with fresh air. Keep the airway open; if breathing is difficult, give oxygen. If breathing and heartbeat stop, perform artificial respiration and chest compression immediately. Seek medical attention.

Protective measures

The production process of this product is operated in a closed manner to provide good natural ventilation conditions. Respiratory protection: Generally no special protection is required. When the oxygen concentration in the workplace air is lower than 18%, an air respirator, oxygen respirator or long tube mask must be worn.

Eye protection: Generally no special protection is required.

Body protection: Wear general work clothes.

Hand protection: Wear general work protective gloves.

Other protection: Avoid inhalation of high concentrations. When entering a tank, confined space or other high-concentration area, supervision is required.

Firefighting measures

This product is generally stored in high-pressure containers. If exposed to high heat, the pressure inside the container will increase, causing the risk of cracking and explosion. The fire extinguishing method is: this product is non-flammable, so move the container away from the fire scene to an open area as much as possible. Spray water to keep the fire container cool until the fire is extinguished.

Leakage emergency treatment

Quickly evacuate people from the leaked contaminated area to a safe area, isolate it, and strictly restrict entry and exit. It is recommended that emergency response personnel wear self-contained positive pressure respirators and general corporate management work clothes. Cut off the source of the leak if possible. Reasonable ventilation will accelerate diffusion. Leaking containers should be properly handled and reused after repair and inspection.
