A sudden carbon monoxide poisoning incident in a cinema has drawn widespread public attention.
Carbon monoxide poisoning occurs when incomplete combustion of carbon-containing substances produces carbon monoxide, which enters the human body through the respiratory tract and causes poisoning. Its poisoning mechanism lies in that the affinity of carbon monoxide for hemoglobin is 200 to 300 times higher than that of oxygen. Therefore, carbon monoxide easily binds to hemoglobin to form carboxyhemoglobin, depriving hemoglobin of its oxygen-carrying capacity and resulting in tissue asphyxia. It is toxic to all human tissue cells, especially severely damaging the cerebral cortex.
Excessive carbon monoxide is extremely hazardous. As a colorless, odorless and non-irritating gas, carbon monoxide causes hypoxia in the human body after inhalation. The severity of poisoning symptoms is related to the carbon monoxide concentration in the air and exposure duration. In the early stage, patients mainly suffer from dizziness, nausea and vomiting. Without timely detection, the worsening symptoms will endanger lives. During the high-incidence period of carbon monoxide poisoning, people need to master prevention methods and first-aid measures. If you are poisoned by carbon monoxide, leave the polluted area immediately, breathe fresh air and ask others for help. When finding poisoned personnel, open windows right away, move the patient away from the scene, loosen their clothes to keep the respiratory tract unobstructed. Turn the patient’s head to one side if vomiting occurs and clear oral and nasal secretions in a timely manner. Perform artificial respiration and chest compressions instantly for suffocated patients and dial emergency number 120 without delay.
Carbon monoxide concentration monitoring in public places such as cinemas cannot be ignored. Daily natural ventilation shall be enhanced to prevent air leakage of delivery pipelines and valves. Carbon monoxide monitoring and alarm devices shall be installed in proper positions. Once the concentration exceeds the standard, the devices will send out timely alarms to remind staff to evacuate people and increase ventilation.
For carbon monoxide concentration monitoring in enclosed spaces like cinemas, the British DDS carbon monoxide gas sensor S+4 2ECO distributed by Shenzhen Wuliang Sensor Technology Co., Ltd. is an ideal choice. This sensor features rapid and sensitive response, strong anti-interference capability, long service life, high precision, excellent repeatability and superior stability. When carbon monoxide exceeds the safe threshold and endangers human health, the carbon monoxide detector will trigger an alarm and upload detected data to the environmental monitoring cloud platform for processing. Managers can keep track of indoor carbon monoxide concentration in real time to guarantee personal safety. Apart from cinemas, it is also applicable to underground parking lots, garages, workshops, enclosed living spaces and other scenarios requiring carbon monoxide detection.
The environmental monitoring cloud platform is a web-based online monitoring system. Users can log in via accounts and passwords on various terminals to realize real-time monitoring of carbon monoxide concentration at all indoor monitoring points. It can push real-time monitoring data, display historical data curves and send alarm notifications to managers via mobile phones, tablets, computers and other terminals, facilitating timely maintenance and ensuring environmental safety.
