Just how harmful is the benzene extraction device to the body?

While benzene does have certain effects on the human body, unnecessary harm can still be avoided with proper handling. If your company’s benzene extraction equipment has excellent airtightness and proper labor protection in place, there is no need to worry so much.

Be sure to take proper protective measures~~After all, health is of the utmost importance~~The benzene extraction unit is a well-developed device; there should be comprehensive protective measures in the workshop. As long as the workshop rules are followed, there shouldn’t be any problems~~But it’s still important to be cautious~~

Yes, working in the chemical industry really requires paying attention to many things!

Chemical substances are inherently toxic. Well, alcohol, which we consider to be the least toxic, still requires the use of gloves when handled; yet for some people it is still considered a hazardous substance, and gloves and masks must be worn when dealing with it. So, when it’s inevitable to come into contact with chemicals, it’s better to be cautious. It’s never a bad idea to take proper protective measures

The fear is that during tasks such as oil removal and purging, or sampling, the surrounding area can have a strong odor; even with masks and rubber gloves on, the skin on the face can still absorb benzene. What’s even more disgusting is the process of removing the solvent – that stench can be smelled even with a mask on. Sometimes I can only sigh and think that maybe this is just how hard life is

Health hazards 　Due to its high volatility, benzene can spread easily when exposed to the air. When humans and animals inhale or come into skin contact with large amounts of benzene, it can cause acute and chronic benzene poisoning. Some studies have shown that part of the cause of benzene poisoning is the formation of phenol in the body from benzene. 　　 Toxicological data LD50: 3306 mg/kg (oral, rats) ； 48 mg/kg (dermal administration in mice) LC50: 10,000 ppm over 7 hours (inhalation in rats). Due to differences in individual health conditions and exposure levels, sensitivity to benzene varies from person to person. When the smell of benzene is detected, its concentration is around 1.5 ppm, and at this point, the risk of poisoning should be taken into consideration. During examination, the degree of benzene poisoning can be easily determined through urine and blood tests. 　　 Exposure limits: China’s MAC is 40 mg/m3 (dermal exposure); the ACGIH limit in the United States is 10 ppm, with a TWA of 32 mg/m3. OSHA’s limit is 1 ppm, corresponding to 3.2 mg/m3. Metabolism: Benzene enters the body primarily through inhalation via the respiratory tract (47–80%), as well as through absorption through the gastrointestinal tract and skin. Some benzene can be excreted through urine, while the unexcreted benzene is first oxidized by molecular oxygen into epibenzene (7-oxabicyclohept-2,4-diene) under the action of cytochrome P450 monooxygenase in the liver. Epoxycyclohexene is in equilibrium with its rearranged product, oxocycloheptatriene, and is a toxic intermediate produced during benzene metabolism. There are three metabolic pathways thereafter: binding to glutathione to form phenylmercuric uric acid ； It continues to be metabolized into phenol, catechol, hydroquinone, pyrogallol, o-quinone, p-quinone, etc., and is excreted in the form of glucuronide or sulfate conjugates ； and is oxidized to adipic acid. Ethanol and toluene can reduce the toxicity of benzene. 　　 Symptoms of poisoning Short-term exposure Benzene has a paralyzing effect on the central nervous system, leading to acute poisoning. In severe cases, symptoms such as headache, nausea, vomiting, confusion, loss of sensation, coma, and seizures may occur; in the most serious instances, death can result from paralysis of the central nervous system. Even small amounts of benzene can cause drowsiness, dizziness, an increased heart rate, headaches, tremors, confusion, and loss of consciousness. Consuming foods containing excessive amounts of benzene can cause symptoms such as vomiting, stomach pain, dizziness, insomnia, convulsions, an increased heart rate, and even death. Inhaling benzene vapor at 20,000 ppm for 5-10 minutes can be fatal. 　　Prolonged exposure: Prolonged exposure to benzene can cause severe damage to the blood and lead to chronic poisoning. It causes neurasthenia syndrome. Benzene can damage the bone marrow, reducing the numbers of red blood cells, white blood cells, and platelets, as well as causing chromosomal abnormalities, which can lead to leukemia or even aplastic anemia. Benzene can cause severe bleeding, thereby suppressing the function of the immune system and allowing diseases to take hold. Some studies have indicated that the incubation period for benzene in the body can be as long as 12–15 years. 　　When women inhale excessive amounts of benzene, it can cause irregular menstruation that lasts for months, and their ovaries may shrink. The effects on fetal development and male fertility are not yet clear. When pregnant animals inhale benzene, it leads to low birth weight in the offspring, delayed bone development, and bone marrow damage. 　　It is irritating to the skin and mucous membranes. The International Agency for Research on Cancer (IARC) has classified it as a carcinogen.

In work environments where there is exposure to volatile organic compounds, it’s best for women, in particular, to minimize such exposure!

I’m more interested in knowing if there are any friends who have been using benzene extraction for at least 8 years, and asking them whether any health problems were detected during their medical check-ups

I worked in the benzene extraction unit for 5 years; back then it seemed that health checks were conducted every six months. My platelet count sometimes drops below the lower limit. But it’s not low every time.

It really does have an impact. Sometimes it’s really frustrating, but there’s nothing you can do if you want to make a living

Don’t pay the price for your health just for short-term gains! If labor protection measures are inadequate or the production equipment does not meet safety standards, then it’s better not to go there. After all, it is one’s health that enables one to have everything; health is the foundation of everything!

If companies pay attention to the safety of their employees’ working environment and choose better equipment, the harm to human health will be much reduced

Although I have not come into contact with the device you mentioned, I still advise you to stay away from it as much as possible. Especially in summer, the risk of absorbing volatile toxic organic compounds through the skin increases, so it is important to take proper precautions. It’s not possible to lose one’s job easily; one must take care of themselves. Eat more protein in daily life, pay attention to nutrition, and exercise more – things will get better eventually.

Really, I think so too. I don’t understand why companies try to save this money; in fact, it’s better to choose better equipment so that the smell emitted isn’t so strong

For now, that’s what I think too, but I really don’t want to spend my whole life working in benzene extraction
