Instructions for Using Toxic Gas Detectors in Underground Operations
Guidance on operating toxic gas detectors underground: The main occupational hazards of working underground are hypoxia and suffocation, hydrogen sulfide poisoning, and combustible gas explosions, with hydrogen sulfide poisoning being the most common phenomenon. The composite gas detector can detect the concentration of toxic and harmful gases in the well in a timely manner and automatically sound an alarm.
1. Carbon dioxide and gas suffocation. For patients who suffer from false death due to carbon dioxide and gas suffocation, in addition to artificial respiration and oxygen therapy, their skin should also be rubbed or exposed to ammonia water to promote breathing recovery. Carbon monoxide poisoning.
2. Hydrogen sulfide poisoning. In addition to artificial respiration or oxygen delivery through a breathing apparatus, cotton balls, handkerchiefs, etc. soaked in chlorine solution can be placed in the mouth for hydrogen sulfide poisoning. Chlorine is a good substance for hydrogen sulfide.
3. Sulfur dioxide poisoning. Due to the formation of sulfuric acid when sulfur dioxide comes into contact with water, it has a strong irritant effect on the respiratory system and may cause burns in severe cases. Therefore, in addition to performing artificial respiration or using a breathing apparatus to deliver oxygen, poisoned patients should be given milk, honey, or rinsed with soda solution to reduce irritation.
4. Poisoning by oxidizing atmosphere. The prominent symptoms of nitrous oxide poisoning include yellowing of fingertips and hair, as well as coughing, nausea, vomiting, and other symptoms. Because nitrogen dioxide poisoning can cause lung edema in the injured, artificial respiration cannot be used. If it is necessary to use a breathing apparatus, carbon dioxide should not be mixed with pure oxygen to avoid stimulating the lungs of the injured. *Good, under the condition of oxygen supply from the breathing apparatus, to enable the injured to breathe autonomously.
5. Carbon monoxide poisoning, shallow and rapid breathing, red spots on the cheeks and body when unconscious, and peach red lips. For poisoned patients, artificial respiration or oxygen therapy with a breathing apparatus can be used. During oxygen therapy, 5% to 7% of carbon dioxide can be infused to stimulate breathing and promote the recovery of respiratory function.
