Is carbon dioxide so powerful? Today, we will introduce you to carbon dioxide, let’s learn together~
What is carbon dioxide?
Carbon dioxide, with the chemical formula of CO2, is a colorless and odorless gas at room temperature and pressure, and its aqueous solution has a slightly sour taste. It is also a common greenhouse gas and a component of air (accounting for 0.03%-0.04% of the total volume of the atmosphere). The density of carbon dioxide is greater than that of air (under standard conditions) and is soluble in water. It cannot burn and usually does not support combustion. Under normal circumstances, carbon dioxide is not a toxic substance, but when the concentration of carbon dioxide in the air exceeds a certain limit, it will cause poisoning in the body, and high concentrations of carbon dioxide will suffocate people.
Application of carbon dioxide
Chemical production: It can be used to synthesize basic chemicals, metal processing, and is also a good raw material for making polymers.
Oil extraction: In the process of exploiting a large number of oil fields at home and abroad, high-pressure carbon dioxide gas is injected to increase oil recovery and balance oil field pressure.
Refrigeration and fire extinguishing: Liquid CO₂ can be used for food freezing, precision instrument low temperature testing, and can also be used as an inert fire extinguishing agent for electrical equipment and precision instrument fire extinguishing.
Food processing: Carbon dioxide can be used in food processing, such as various types of sparkling water, cola and other carbonated beverages; if it is kept fresh and cold with dry ice bags, the preservation time is longer than that of traditional ice cubes.
Medical and scientific research: Carbon dioxide can be used for respiratory therapy and minimally invasive surgery, and can also be used for supercritical extraction and laboratory reagents during experiments.
Agricultural applications: It can be used to make greenhouse gas fertilizers and feed additives.
Hazards of carbon dioxide leakage
Hazard of suffocation: When the concentration of carbon dioxide exceeds the safe level, the oxygen content in the air will decrease, leading to the risk of suffocation. Especially in confined spaces or places with limited ventilation, the risk is greater.
Fire and explosion: High concentrations of carbon dioxide can form flammable and explosive mixtures in the air, which may cause fire or explosion once encountering a fire source.
Health effects of long-term exposure: Long-term exposure to high concentrations of carbon dioxide may have long-term effects on health, such as respiratory diseases and neurological problems.
Environmental pollution: Leaked carbon dioxide can cause soil acidification, plant withering and even death. Excessive carbon dioxide emissions can also cause global warming.
Emergency treatment of carbon dioxide leakage
When poisoning is found
— Ensure the safety of the rescuer and wear appropriate personal protective equipment.
— Immediately transfer the poisoned person to a well-ventilated place to avoid continued exposure to a high concentration of carbon dioxide.
— If breathing stops, immediately perform cardiopulmonary resuscitation and artificial respiration.
Call the police for help
— While ensuring your own safety, call the emergency number for professional rescue, such as 120 emergency or fire.
First aid measures
— For people who are conscious but have mild symptoms of poisoning, send them to a well-ventilated place to rest and observe their symptoms.
— For people who are unconscious or severely poisoned, cardiopulmonary resuscitation and artificial respiration should be performed immediately, and wait for professional medical staff to arrive.
How to prevent carbon dioxide leakage?
Regularly check equipment: Regularly check and maintain industrial equipment, household gas equipment, etc. to ensure their normal operation and reduce the possibility of accidents.
Strengthen ventilation: Keep indoor air circulation, increase ventilation equipment, and promptly remove harmful gases such as carbon dioxide to reduce the risk of accidents.
For enterprises, these precautionary awareness is far from enough. Choosing a suitable carbon dioxide gas detector, real-time monitoring, and timely warning is the most reliable method.
Starting from user needs, Chicheng Electric has developed a carbon dioxide gas safety solution, providing an innovative and efficient way to solve the problem of carbon dioxide leakage and prevention.
Real-time monitoring and early warning: Continuously monitor the CO₂ concentration in the air. When the concentration exceeds the preset threshold, the detector will immediately trigger an audible and visual alarm to remind the staff to take emergency measures.
Linkage control: The carbon dioxide detector is linked with the ventilation system, exhaust equipment, emergency shut-off valve, etc. When the alarm is issued, it can automatically start exhaust or cut off the leakage source to form a closed-loop safety protection.
Data analysis: Massive data storage can help on-duty personnel analyze the occurrence of accidents and block the source of danger from the source.
Risk prevention and control: Installing a carbon dioxide detector can effectively prevent the risk of suffocation caused by CO₂ leakage, especially in confined spaces (such as basements, wine cellars, and industrial storage tank areas), which can avoid casualties.
Solution Advantages
01 Prevention First Reduce Accident Rate: Through real-time monitoring and linkage control, the accident response time is shortened from 30 minutes of manual inspection to within 30 seconds, effectively reducing the accident rate.
02 Intelligent linkage: When the sound and light alarm signal is issued, the controller can also link the fan, sprinkler and other devices to prevent accidents.
03 Intelligent management: The Internet of Things platform realizes remote monitoring, and data traceability supports accident investigation.
04 Cost optimization: Avoid production suspension fines due to excessive CO₂, and save compliance costs in the long term. In addition, high concentrations of CO₂ may accelerate the corrosion of metal equipment. Installing detectors can provide early warning to take protective measures and save costs.
There is no small matter in safe production. As a “pioneer” in gas leak warning, Chicheng Electric’s carbon dioxide detectors have been widely used in many industries such as petroleum, chemical, electricity, natural gas, medicine, environmental protection, warehousing, and grain, always protecting the safe production of enterprises and the health of personnel!
