What precautions should be taken after a person inhales a large amount of ammonia 5

In fact, if you don't inhale a large amount of ammonia for a long time, there will be no disease, if you just inhale it for the first time, the body's metabolic system will be slowly metabolized.

Answer]: When the operator unloads ammonia and deals with dangerous gas leakage, he must be accompanied by at least two people, wear protective clothing, gas masks, protective glasses, protective gloves, and air hole respirators as required. Maintenance and maintenance personnel must use copper tools as required.

If ammonia is inhaled, it should be quickly removed from the scene to a place of fresh air and immediately seek medical attention. （）

a.That's right. b.The staggered bridge slowly collapsed by mistake.

Correct Answer: a

1. First aid measures for ammonia leakage.

The principles of emergency treatment of ammonia leakage are:"Save people.

First, the second is to save things"，"Prevention of proliferation.

First, reduce losses second"。The focus of safety management prevention in ammonia zones is on leakage prevention and explosion prevention. In the event of an accident, treatment decisions are based on the amount of ammonia detected by the ammonia monitor. Take the right treatment measures according to the size of the ammonia leakage.

1. Slight leakage of ammonia.

1) Do a good job of personal protection, close the relevant valves, and prevent ammonia from leaking;

2) Quickly rescue the trapped and victims, and report to the relevant leaders;

3) Mark the site according to the scope of danger, block the scene, and organize maintenance personnel to carry out emergency repairs to minimize the degree of ammonia leakage.

2. A large amount of ammonia leakage.

1) The emergency rescue command and leading group immediately takes rescue actions and sets up rescue operation areas.

2) The emergency rescue operation team is engaged in emergency rescue, and quickly organizes personnel in the leakage and pollution area to go upwind, and strictly prohibits unrelated personnel from entering and leaving. Emergency responders should wear self-contained positive pressure respirators, anti-static overalls, and cut off the source of leakage as much as possible.

3) In the event of a fire or accident, the first thing to do is to"119"、"110"Call the police, and then immediately take partial or total power-off measures, and organize personnel to extinguish the fire to prevent the accident from further expanding. If there are personnel, the wounded should be rescued immediately, and at the same time"120"Distress.

4) According to the wind direction and the scope of ammonia, command the masses to protect and organize evacuation, focusing on protecting the safety and health of the population.

5) Do a good job in accident scene protection, vigilance and accident handling.

6) Firefighters must wear full-body fireproof and anti-poison clothing to extinguish the fire from the upwind direction to cut off the gas source.

2. Personnel first aid measures.

1)**Contact: Immediately remove contaminated clothing, rinse thoroughly with 2% boric acid solution or plenty of water, and seek medical attention immediately.

2) Eye contact: Lift the eyelids immediately, rinse the eyes thoroughly with plenty of running water or saline for at least 15 minutes, and seek medical attention immediately.

3) Inhalation: Quickly leave the scene to a place with fresh air to keep the respiratory tract unobstructed. If it is difficult to breathe, oxygen is given; If breathing stops, give rescue breaths immediately and seek medical attention promptly.

Disposal personnel should take necessary personal protective measures, and should wear insulated chemical protective clothing and air respirators when disposing of leaks or related equipment. When in direct contact with liquid ammonia, wear cold-proof clothing. In case of emergency, you can also wear cotton clothes and pants, tighten the sleeves of the trousers, and cover your mouth and nose with a soaked mask.

Third, all ignition sources and flammable materials in the leakage area should be quickly removed, and ventilation should be strengthened. If the cylinder leaks, use a non-sparking tool to prevent a large amount of liquefied gas from flowing upwards with the leakage port facing upwards as much as possible. When valve shut-off and plugging measures are ineffective, consider immersing the cylinder in water or dilute acid solution, or transferring it to an open area for decontamination.

Fourth, the leakage of liquid ammonia should be dispersed with mist water and flowering water. Disposal should be done to prevent spills from entering water streams, sewers, or some control areas. Fifth, in the event of a fire, mist water, flowering water, anti-solvent foam, sand or CO2 should be used to extinguish the fire, and at the same time, pay attention to cooling the container wall with a large amount of direct water.

If possible, move movable items out of the fire as soon as possible. If there are dangerous signs, such as louder vents or discolored container walls, you should retreat immediately.

Ammonia is a toxic gas, and tail gas treatment should be considered when it is produced. The cotton at the mouth of the test tube absorbs ammonia and prevents it from escaping into the air. The cotton at the mouth of the test tube also needs to be soaked in order to collect purer ammonia.

When preparing ammonia in the laboratory, in order to prevent excess ammonia from being dissipated into the air, dilute hydrochloric acid (or dilute sulfuric acid) can be used to absorb acidic liquids. 】

Use water to absorb ammonia that may spill.

Absorbed with water, synthesized with acid.
