Social assistance team into the company's command should set up a person to contact and inform the safety precautions.
Nine, carbon dioxide (gas, liquid) related to general knowledge
1. Physical properties
Carbon dioxide (carbondioxide, CO2) for; 2. Occupational exposure; carbon dioxide is used in the manufacture of soda, beer and other beverages, fire extinguishing agents, dry ice,; earthen storage of vegetables, fruits, grains of the cellar, the long term sealing of methane digesters; 3. Poisoning symptoms ;Mild poisoning with dizziness, headache, fatigue, drowsiness, tinnitus, palpitations, ;Severe poisoning is often paralyzed and comatose within seconds of entering the scene, if not ;X. Implementation of the Emergency Preparedness Plan ;This plan has been implemented since the date of publication ;Annex I ;
Carbon dioxide (carbon dioxide, CO2) is a colorless, odorless, non-combustible gas. Molecular weight 44.01, density 1.527g/L, soluble in water to the extent of 171ml/100ml (0 ℃) and 36ml/100ml (60 ℃), the pressure increases, water solubility increases.
2. Occupational exposure
Carbon dioxide is used in the manufacture of beverages such as soft drinks and beer, fire extinguishers, dry ice, sodium bicarbonate, and the fermentation industry, and there is exposure to CO2 in these production processes.
The cellar where vegetables, fruits, and grains are stored in the soil, and the long-term sealed biogas digester into the sewer can produce high concentrations of CO2, which can cause severe hypoxia and asphyxia when suddenly entering and lacking protection.
3. Symptoms of poisoning
Mild poisoning with dizziness, headache, fatigue, drowsiness, tinnitus, palpitations, chest tightness, blurred vision and other discomforts, respiratory excitation followed by inhibition, there can be pupil constriction, pulse retardation, elevated blood pressure or fuzzy consciousness, and timely detachment from the scene, the recovery is relatively smooth.
Severe poisoning is often paralyzed and comatose within seconds after entering the scene, if not rescued in time, it is easy to cause death. Those who are rescued are still often in a coma, incontinence, loss of reflexes, vomiting, and even shock and respiratory arrest. After rescue treatment, relatively light cases may gradually wake up in a few hours, but dizziness, headache, fatigue, etc. still need a few days to recover; relatively serious cases continue to be comatose, and high fever, convulsions, respiratory distress, exhaustion or shock and other critical symptoms. Solid (dry ice) and liquid carbon dioxide vaporize rapidly at atmospheric pressure, can cause -80 ~ -43 ℃ low temperature, causing severe frostbite on the skin and eyes.
