Hydrogen sulfide in confined space operation is a colorless, highly toxic, acidic gas, with rotten egg odor, molecular weight 34.076. Under standard conditions, hydrogen sulfide is a flammable acid gas, at low concentrations there is rotten egg odor, at very low concentrations there is sulfur smell. Hydrogen sulfide is a kind of asphyxiating gas, once poisoned, the death rate is high, known as "poisoning killer".

Hydrogen sulfide poisoning often occurs in pipeline dredging, sewage silting and other hydrogen sulfide confined space operations, which should cause high vigilance. In confined space operation, hydrogen sulfide may exist in waste water, waste gas and waste residue, causing harm to human health. Therefore, in the confined space operation, hydrogen sulfide must be monitored and warned, and corresponding protective measures must be taken to ensure the safety of operators.

At low concentrations, hydrogen sulfide smells as a rotten egg, but high concentrations of hydrogen sulfide gas not only cannot smell, but also directly paralyze the olfactory nerve. When the concentration of hydrogen sulfide in the air reaches 1000mg/m³, inhalation may cause death in few seconds. Therefore, for hydrogen sulfide in confined space operations, we must be highly vigilant and take effective protective measures to ensure the safety of operators. At the same time, if hydrogen sulfide poisoning accidents occur, emergency plans should be immediately activated for rescue and treatment.

Hydrogen sulfide is a toxic gas with strong irritant and corrosion, which can cause acute poisoning and chronic harm to human body. In confined space, such as petroleum, chemical, coal and other industries, hydrogen sulfide hazards are more common, so understanding the nature of hydrogen sulfide and protective measures is essential to ensure the health and safety of operators.

In the case of hydrogen sulfide leakage in confined space, emergency plans should be immediately activated, evacuated from the scene and promptly reported to the relevant departments. Persons with acute poisoning should be given immediate first aid and treatment. For people who have been exposed to hydrogen sulfide for a long time, regular health checks and medical observation should be carried out. Hydrogen sulfide in confined space operations is a dangerous chemical with potential hazards to human health and safety. Therefore, understanding the properties of hydrogen sulfide and protective measures are crucial. In actual work, effective protective and management measures should be taken to ensure the health and safety of operators.
