。 Speaking of ammonia poisoning, everyone must be familiar with it. Pollution from decoration in daily life and ammonia leakage in chemical sites will cause ammonia poisoning . So what are the dangers of ammonia poisoning? How to prevent ammonia poisoning?
What is ammonia?
Ammonia (NH3) is a colorless gas with a strong pungent odor. 和刺激作用。 Ammonia is an alkaline substance that has a corrosive and irritating effect on the skin tissues that come into contact . Ammonia can absorb moisture in skin tissue, denature tissue proteins, saponify tissue fat, and damage cell membrane structure. The solubility of ammonia is extremely high, so it has a stimulating and corrosive effect on the upper respiratory tract of animals or humans, and weakens the human body's resistance to diseases. 了腐蚀作用外，氨还可通过三叉神经末梢的反射作用而引起心脏停搏和呼吸停止。 In addition to the corrosive effect, ammonia can also cause cardiac arrest and respiratory arrest through the reflex effect of the trigeminal nerve endings.
氨被吸入肺后容易通过肺泡进入血液，与血红蛋白结合，破坏运氧功能。 Harm of Ammonia Poisoning: After being inhaled into the lungs, ammonia easily enters the blood through the alveoli and combines with hemoglobin to destroy the oxygen transport function. 流泪、咽痛、声音嘶哑、咳嗽、痰带血丝、胸闷、呼吸困难，可伴有头晕、头痛、恶心、呕吐、乏力等 ，严重者可发生肺水肿、成人呼吸窘迫综合征，同时可能发生呼吸道刺激症状。 After inhaling a large amount of ammonia in a short period of time, tearing, sore throat, hoarseness, cough, bloodshot sputum, chest tightness, dyspnea, and dizziness, headache, nausea, vomiting, fatigue, etc. may occur. In severe cases, pulmonary edema and adult Respiratory distress syndrome, and respiratory tract irritation may occur at the same time.
Prevention of ammonia poisoning:
应，如果是浓度极高的氨气对人的危害更为严重。 In daily life, ammonia can be released or produced in many places or places, and people who often come into contact with ammonia will have a series of adverse reactions . If the ammonia concentration is extremely high, it will be more harmful to people. Therefore, we should know how to prevent ammonia poisoning.
1. Ammonia detection and preventive measures. During the production process, the airtightness should be strengthened, and the liquid ammonia pipeline valve should be overhauled frequently to prevent accidental rupture. 强通气，使车间空气中氨气最高容许浓度控制在30mg/L。 Strengthen ventilation to control the maximum allowable concentration of ammonia in the air of the workshop at 30mg / L. 受震动，以免膨胀炸裂；使用时应严格遵守安全操作规程，使用防毒面具等安全防护工具，做好个人防 护。 When storing and transporting liquid ammonia or ammonia water, it should be protected from heat and sun, and from vibration to avoid expansion and cracking. When using it, strictly follow the safe operating procedures, and use safety protective tools such as gas masks for personal protection .
2. Organize drills for emergency rescue work. 与临床抢救治疗程序。 The first aid procedures for mass acute ammonia poisoning must be clarified, that is, on-site rescue procedures and clinical rescue treatment procedures.
肾脏疾病、心血管疾病者应禁忌从事氨作业。 3. Strict implementation of the "Ammonia Standard" stipulates that all persons engaged in ammonia operations should undergo pre-employment medical examinations. Those with obvious respiratory diseases, liver or kidney diseases, and cardiovascular diseases should be prohibited from engaging in ammonia operations. According to the contact situation, the operator will undergo a physical examination every 1 to 2 years.
4. Don't move into the new building immediately. Open the windows for a period of time. Use as little decoration materials as possible in the interior with additives and brighteners.
5. In the case of animal husbandry, reasonable site selection and scientific design should be adopted. 良好，周围无居民区、无化工厂、屠宰场和矿区的等污染较多地方。 For pig farms, it should be selected in places with high and dry terrain, open terrain, convenient drainage, and good ventilation . There are no residential areas, chemical factories, slaughterhouses and mining areas with more pollution. 水等废弃物，通风换气良好， Completely and timely discharge waste such as feces, litter and sewage , with good ventilation and ventilation,
Minimize the generation of harmful gases in the house.
In short, for our health, we must start with ourselves and learn to apply safety protection tools to minimize the harm of ammonia.
