When it enters the water body, it may change the pH of the water, affect the living environment of aquatic organisms, cause damage to the aquatic ecosystem, lead to the death of fish, plankton, etc., and then affect the balance of the entire food chain. In the atmospheric environment, its volatile components may chemically react with other substances to form harmful chemicals, exacerbate the degree of atmospheric pollution, and negatively affect air quality and ecological balance.
【 Explosion hazard 】
Although the product itself is not flammable, it will not burn and explode as easily as flammable substances, but it has a certain irritation. Under certain conditions, such as when mixed with other combustible substances, subjected to high temperature or open flame, it may cause chemical reactions and release irritating gases, causing harm to site personnel and the surrounding environment. Therefore, in the process of storage and use, it is still necessary to pay great attention to its potential explosion risk.
First aid measure
【 Skin contact 】
Once the skin comes into contact with the source of contamination of the product, immediate action should be taken to reduce the harm. First, quickly remove contaminated clothing to avoid further contact with the skin. Then, rinse the contaminated skin area with plenty of flowing water for a long time to ensure that the remaining contaminants are thoroughly washed away. During the flushing process, the skin can be gently rubbed, but care should be taken to avoid excessive force causing skin damage. If the skin appears red, swollen, itching and other uncomfortable symptoms, should be timely medical treatment, seek professional help.
【 Eye contact 】
The situation is more urgent when eyes come into contact with the product. At this time, the eyelids should be lifted immediately, so that the eyes are fully exposed, and then the eyes should be continuously rinsed with a large amount of flowing water or normal saline for no less than 15 minutes. During the flushing process, the victim should keep moving his eyes to ensure that all parts can be fully flushed. After the irrigation is completed, the injured person should be accompanied to the hospital as soon as possible for further examination and treatment by a professional ophthalmologist to prevent eye damage from worsening.
【 Inhale 】
If the volatile gas or dust of the product is inhaled at the site, it should be removed from the site immediately and transferred to a place with fresh air. Give the victim fresh air to keep the airway clear. If the victim has symptoms of breathing difficulties, oxygen should be given immediately to relieve the hypoxia. At the same time, it is necessary to closely observe the vital signs of the injured, such as breathing, heartbeat and other changes, and call the emergency number in time to send the injured to the hospital for treatment to ensure the life safety of the injured.
【 eat 】
If the product is accidentally ingested, the first thing to do is to let the injured drink enough warm water to dilute the concentration of pollutants in the stomach and reduce the irritation of the gastrointestinal tract. Vomiting can then be attempted, prompting the victim to spit out unabsorbed contaminants from the stomach. However, it should be noted that the emetic operation should be carried out under the guidance of professional personnel to avoid suffocation or other accidents caused by improper operation. After vomiting, the injured person should be accompanied to the hospital as soon as possible for further treatment and observation to ensure that there are no other abnormalities in the body.
Fire protection measures
【 Hazardous characteristics 】
When the product is heated, it will undergo decomposition reaction, which will release toxic gases such as nitrogen and sulfur oxides. These toxic gases have strong irritant and corrosion, which will not only cause serious injury to the respiratory tract and eyes of the on-site personnel, but also may cause corrosion damage to the surrounding equipment and buildings. In addition, under certain conditions, these toxic gases may also have a chain reaction with other substances in the air, further expanding the scope of the accident.
【 Harmful combustion products 】
In the process of combustion or thermal decomposition, the product will produce carbon monoxide, carbon dioxide, sulfide, nitrogen oxide and other harmful combustion products. Carbon monoxide is a highly toxic gas that binds to hemoglobin and reduces the oxygen-carrying capacity of the blood, resulting in a lack of oxygen in human tissues and organs, which can be life-threatening in severe cases. Although carbon dioxide itself is non-toxic, at a certain concentration it will cause the oxygen content in the air to decrease, making people feel suffocated. Gases such as sulphides and nitrogen oxides have strong pungent odors that can irritate the respiratory tract and eyes, causing serious harm to the environment and human health.
【 Fire extinguishing method 】
When a fire occurs involving this product, firefighters must take strict protective measures. First of all, to wear the whole body fire protective clothing to ensure their own safety. In the process of fire fighting, the operation should be selected in the upwind direction to avoid the harm of smoke and toxic gases to firefighters. At the same time, it is necessary to move the container storing the product from the fire to an open and safe place as far as possible to prevent the container from cracking or exploding at high temperatures, further expanding the scope of the accident. During the fire extinguishing process, the appropriate fire extinguishing agent can be selected according to the actual situation to extinguish the fire, but it is necessary to ensure that the fire extinguishing agent will not react with the product, so as not to cause more serious consequences.
Leakage emergency treatment
【 Emergency treatment 】
In the event of a leakage accident of the product, measures should be taken immediately to isolate the contaminated area of the leak, set up warning signs, limit the access of non-emergency personnel, and prevent irrelevant personnel from coming into contact with the leak and being hurt. It is recommended that emergency personnel wear professional dust masks (full-face masks), wear protective clothing, and take personal protective measures before entering the site for handling. In the process of cleaning the leak, to avoid the occurrence of dust phenomenon, you can use a broom and other tools to carefully sweep up the leak, and then placed in a sealed bag transferred to a safe place for proper disposal. If the amount of leakage is large and difficult to clean with conventional methods, plastic sheets, canvas, etc. can be used to cover the surface of the leakage to prevent its further diffusion and volatilization. Finally, the collected leakage is recycled or transported to a special waste treatment site for disposal to ensure that it does not cause secondary pollution to the environment.
