Manifestations of hydrogen sulfide poisoning

User:JXCTUpload time:Sep 26 2021

Hydrogen sulfide is a highly toxic gas, and hydrogen sulfide sensor is commonly used in the industry to detect it. Hydrogen sulfide is a flammable acid gas, colorless but odorous. When the concentration is extremely low, there is a smell of sulfur. At low concentrations, there is a smell of rotten eggs. After being mixed with air, it can burn and explode in an open flame.

What are the symptoms of moderate hydrogen sulfide
Mild poisoning

Mild poisoning is mainly irritation symptoms. It is manifested as watery eyes, tingling eyes, runny nose, and burning sensation in the throat. Or accompanied by headache, dizziness, fatigue, nausea and other symptoms. Examination shows conjunctival hyperemia and rales in the lungs. It can be recovered within a short period of time after disengagement.

Moderate poisoning

Encephalopathy is notable after exposure to high concentrations of hydrogen sulfide. Headache, dizziness, irritability, staggering gait, irritability, confusion, and delirium appear. Epilepsy-like convulsions can be generalized tonic-clonic seizures. A coma may occur suddenly, breathing difficulties may occur, or the heart may stop after breathing has stopped. Fundus examination revealed optic nerve head edema in individual cases. Some cases may be accompanied by pulmonary edema. Symptoms of encephalopathy often appear earlier than respiratory symptoms. Chest X-ray showed enhanced lung texture or flaky shadows.

Severe poisoning

Electrical shock-like death can occur after exposure to extremely high concentrations of hydrogen sulfide. That is, respiratory arrest within a few seconds or minutes after contact, heartbeat may stop within a few minutes. He may also fall into a coma immediately or within a few minutes, and die from respiratory arrest. Death can occur without alertness. When the odor of hydrogen sulfide is detected, the sense of smell can be immediately lost. In a few cases, the disgusting sweetness can be smelled immediately before the coma. Before death, there is generally no aura symptoms, but deep and rapid breathing may occur first, followed by sudden respiratory arrest.

The hydrogen sulfide detector provides a safe way to detect hydrogen sulfide

Hydrogen sulfide sensor has fixed explosion-proof type and portable type. Suitable for hydrogen sulfide gas detection in various occasions. Small size, high sensitivity, and quick response. It can respond quickly to hydrogen sulfide gas leakage and send out audible and visual alarms. Greatly reduce the harm caused by toxic gas leakage.
