Guidance on the operation method of toxic gas detector in underground
Guidance on the operation method of toxic gas detectors in underground mines: the main occupational hazards for everyone working underground are hypoxia suffocation, hydrogen sulfide poisoning and combustible gas explosions, and the most common phenomenon is hydrogen sulfide poisoning. The composite gas detector can detect the concentration of toxic and harmful gases in the well in time, and can automatically alarm.
1. Carbon dioxide and gas suffocation. In addition to artificial respiration and resuscitation oxygen infusion, the wounded caused by carbon dioxide and gas suffocation should also rub their skin or let them smell ammonia water to promote recovery of breathing. poisoned by carbon monoxide.
2. Hydrogen sulfide poisoning. For hydrogen sulfide poisoning, in addition to artificial respiration or resuscitator oxygen delivery, cotton balls and handkerchiefs soaked in chlorine solution can be put into the mouth. Chlorine is a good substance for hydrogen sulfide.
3. Sulfur dioxide poisoning. Because sulfur dioxide meets water to form sulfuric acid, which has a strong stimulating effect on the respiratory system and may cause burns in severe cases. Therefore, in addition to artificial respiration or resuscitator oxygen delivery, the poisoned wounded should be given milk, honey or gargle with soda solution to relieve the poisoning. Stimulate.
4. Atmosphere poisoning. The most prominent symptoms of atmospheric dioxide poisoning are fingertips, yellowing of hair, and symptoms such as coughing, nausea, and vomiting. Because nitrogen dioxide poisoning will cause pulmonary edema in the wounded, artificial respiration cannot be used. If a resuscitator must be used for resuscitation, pure oxygen cannot be mixed with carbon dioxide to avoid stimulating the lungs of the wounded. Allow the casualty to breathe spontaneously, preferably with oxygen from a resuscitator.
5. Carbon monoxide poisoning, shallow and rapid breathing, erythema on cheeks and body when unconscious, pink lips. Artificial respiration or oxygen delivery with a resuscitator can be used for the poisoned wounded. When infusing oxygen, 5% to 7% carbon dioxide can be infiltrated to stimulate breathing and promote the recovery of respiratory function.
