In the laboratory, many chemical substances often have a smell, and the taste of some substances can even make life irresistible, such as isovaleraldehyde - smelly feet, proline - semen smell, hydrogen sulfide - rotten egg, allyl isothiocyanate - pure mustard, isoamyl acetate - classic banana scent
.
Once, six people died in the warehouse of a pesticide factory in a city in southwest China
.
Anyone who has done chemical experiments knows that hydrogen sulfide is a gas with a strong pungent odor
.
The reason why the six workers hid in the warehouse that day was because it was pouring rain outside, and there was a leak in the warehouse.
A lot of hydrogen sulfide
.
Is hydrogen sulfide really so poisonous? Yes, hydrogen sulfide is called "mysterious killer" by people
.
On June 12, 2008, a hydrogen sulfide poisoning accident occurred in Anning Qitian Fertilizer Co.
, Ltd.
, Kunming City, Yunnan Province, during the trial production of dearsenic and refined phosphoric acid, resulting in 6 deaths and 29 poisonings
.
At about 5:10 on March 3, 2019, a hydrogen sulfide gas poisoning accident occurred in the phosphoric acid filling area of the Logistics Department of Weng Fudazhou Chemical Co.
, Ltd.
, resulting in 3 deaths and 3 injuries
.
The harm of hydrogen sulfide to the human body and the impact of its disasters are shocking and shocking the whole country
.
In addition to hydrogen sulfide, there is a common chemical gas that also has this property, paralyzing the respiratory nerves
.
That is ammonia
.
Unlike hydrogen sulfide, low-concentration ammonia can quickly cause olfactory fatigue.
High-concentration ammonia can make you instantly alert, but if your working environment is low-concentration ammonia, it is very dangerous.
, Because after smell fatigue, you can't smell, and by the time you find that you have symptoms of difficulty breathing, coughing, and chest tightness, it may be too late
.
Summarize the two poisonous gases that paralyze the respiratory system: hydrogen sulfide gas, which is very smelly at low concentrations and can play a role in alertness
.
Ammonia, when the concentration is low, can quickly fatigue the sense of smell, paralyze the sense of smell, and cause poisoning; when the concentration is high, it can act as an alert
.
So when contacting or using these two chemicals, be sure to wear a gas mask and don't trust your sense of smell
.
