What is the detection method of the composite gas detector
There is a difference between the detection of toxic gases and other gases. We should pay attention to the description of the detection of toxic gases in gas detection when we are detecting. Among them, there are instructions for some poisoning problems that may occur if we do not pay attention during the detection process. If signs of poisoning appear during use, immediate medical attention is recommended. The following is our explanation of some signs of occupational poisoning that appear during the detection process of the composite gas detector!
(1) Occupational poisoning Production poisons can cause occupational poisoning. Occupational poisoning can be divided into three types according to the pathogenesis process. Acute poisoning: caused by a large amount of poison entering the human body at one time or in a short period of time. Most of them are caused by production accidents or violations of operating procedures.
Chronic poisoning: Chronic poisoning refers to the long-term small amount of poison entering the body. The vast majority are caused by cumulative poisons. Subacute poisoning: Subacute poisoning is between the above two, and the poisoning phenomenon occurs when a relatively large amount of poison enters the human body within a short period of time.
(2) Exposure to industrial poisons in a poisoned state, but without poisoning symptoms and physical symptoms, the amount of poisons (or metabolites) contained in urine or other biological materials exceeds the upper limit of normal values; or flooding tests (such as flooding of lead, flooding mercury) positive. This state is called a toxic state or a state of poison absorption, such as lead absorption.
(3) Other occupational diseases such as beryllium can cause beryllium lung; fluorine can cause skeletal fluorosis; vinyl chloride can cause acral osteolysis; tar pitch can cause skin melanosis and so on.
(4) Mutagenic, carcinogenic, and teratogenic Some chemical poisons can cause mutations in the genetic material of the body. Chemical substances that have a mutagenic effect are called chemical mutagens. Some chemical poisons can cause cancer, and chemicals that can cause cancer in humans or animals are called carcinogens. Some chemical poisons have toxic effects on embryos and can cause deformities. These chemicals are called teratogens.
(5) Effects on reproductive function Industrial poisons can affect the reproductive functions of female workers such as menstruation, pregnancy, and breastfeeding, which is not only harmful to women themselves, but also affects the next generation. Female workers exposed to benzene and its homologues, gasoline, carbon disulfide, and trinitrotoluene are prone to menorrhagia syndrome; female workers exposed to lead, mercury, and trichlorethylene are prone to hypomenorrhea syndrome. Chemical mutagens can cause germ cell mutations and cause teratogenicity, especially in the first trimester after pregnancy, when embryos are sensitive to chemical poisons*. In the process of embryonic development, certain chemical poisons can cause retardation of fetal production, deformity of embryonic organs or systems, and death or absorption of fertilized eggs. Both organic mercury and polychlorinated biphenyls have teratogenic effects. Male workers exposed to carbon disulfide can reduce their sperm count and affect their fertility; lead and dibromochloropropane also have an impact on male reproductive function. Lead, mercury, arsenic, carbon disulfide, etc. can enter the baby's body through milk, affecting the health of the next generation.
Through the above, we know that we should pay attention to the protective effect when using the composite gas detector for detection, otherwise we will not know what happened if poisoning occurred during the detection process. Toxic gas is very harmful to us, for example, it can even cause cancer and fatal damage to our reproductive system or respiratory tract! Composite gas detectors must pay attention to these problems when testing!
