In news reports, there are always articles about people falling into septic tanks and dying from poisoning, and people dying from inhaling too much factory exhaust gas. What are the reasons for these? The main culprit is actually hydrogen sulfide poisoning. What is hydrogen sulfide?
Hydrogen sulfide is actually a sulfur-containing hydride with the chemical formulaH2SMixing with air can easily cause explosions. It is a colorless acidic gas with a foul odor. At low concentrations, it has a rotten egg odor, and at extremely low concentrations, it has a sulfur odor. The higher the concentration, the less likely the odor is to be smelled, with a strong odorWhen the concentration exceeds10mg/mThere is a risk of death with 3. It can be imagined that if the human body consumes too much hydrogen sulfide, the risk factor is very high. Hydrogen sulfide is commonly used in the synthesis of fluorescent powders, as well as in the manufacture of electroluminescent devices, light conductors, and photoelectric exposure meters. Organic synthesis reducing agent. Used for metal refining, pesticides, pharmaceuticals, and catalyst regeneration. General reagents. Produce various sulfides.

Hydrogen sulfide is mainly produced in urban sewage pipelines, septic tanks, mines, and pulp mills....In places with poor air circulation, the lack of ventilation creates conditions where hydrogen sulfide gas continuously accumulates, leading to a continuous increase in concentration. That's why many tragic cases have occurred. Since hydrogen sulfide poses a great threat, how can I avoid it?
1. Install according to national standards and regulationsfixed/Portable gas concentration detector, real-time monitoring and alarm.
2. Provide safety training for personnel involved in hazardous operations. In the event of a gas leak, restrict access and cut off sources of ignition. It is recommended that emergency personnel wear air respirators and chemical protective clothing.Enter the site from the upwind direction, cut off the leakage source as much as possible, ventilate reasonably, and accelerate diffusion. Use spray water to dilute, dissolve and build a dike or dig a pit to collect a large amount of wastewater generated. If possible, use an exhaust fan to send the toxic gas into the water washing tower or a fume hood connected to the tower. Leakage containers should be properly handled, repaired, and inspected before reuse.
3. Storage and transportation precautions: Hydrogen sulfide is a flammable and toxic compressed gas. Store in a cool and ventilated warehouse. The warehouse temperature should not exceed30℃. Keep away from sources of fire and heat. Keep the container sealed. Prohibit the use of instruments and tools that are prone to sparking. Light loading and unloading during transportation. Transport should follow the prescribed route and avoid stopping in residential and densely populated areas.
