Occupational poisoning remains one of the most severe occupational health issues in China, often concentrated in specific industries and occurring in mass incidents from time to time. It not only endangers the safety and well-being of workers but also disrupts economic growth and social stability. A closer look at recent cases reveals that many are due to a lack of basic occupational health knowledge, weak protective awareness, and insufficient safety measures among workers. Therefore, preventing occupational poisoning is crucial for overall occupational disease control.
To address this issue, the magazine has launched a dedicated section called “Concern for Occupational Safety and Health.†This initiative will publish informative articles and surveys from the Labor Protection Department of the National Federation of Trade Unions, aiming to educate migrant workers and promote safe working conditions.
What is occupational poisoning? It occurs when individuals are exposed to harmful chemicals during work processes. Acute poisoning can result from short-term exposure to high concentrations of toxins, while chronic poisoning develops from long-term exposure to lower levels. Chronic cases often have prolonged latency periods and can lead to serious health consequences.
How do chemical poisons enter the body? They typically enter through the respiratory tract, skin, or gastrointestinal system. The respiratory tract is the most common route, as many toxic substances are inhaled and quickly absorbed into the bloodstream. Skin contact can also be dangerous, especially with chemicals like organophosphates or corrosive materials. Ingestion, though less common, can occur through contaminated food or water.
Where do chemical toxins appear in the workplace? They may be present during raw material extraction, handling, feeding, chemical reactions, waste treatment, maintenance, and other operations. For example, dust, vapors, and fumes are common in mining, smelting, and chemical manufacturing.
Preventing occupational poisoning requires a comprehensive approach. Employers should identify hazards, conduct risk assessments, and implement engineering controls, management strategies, and personal protection measures. Training workers, maintaining equipment, and ensuring proper ventilation are also essential.
Personal protective equipment (PPE) plays a vital role in reducing exposure. Masks, goggles, gloves, and protective clothing are necessary depending on the type of toxin and the method of exposure. Proper use and maintenance of PPE are critical to ensure effectiveness.
Common causes of acute occupational poisoning include lack of training, improper use of protective gear, poor ventilation, and unsafe work practices. Chemicals such as hydrogen sulfide, carbon monoxide, chlorine, and benzene are frequently involved in such incidents.
Acute poisoning is more common in industries like chemicals, construction, mining, and water treatment. Workers involved in cleaning, maintenance, and excavation are at higher risk.
In conclusion, preventing occupational poisoning is a shared responsibility. By improving education, enforcing safety protocols, and using appropriate protective measures, we can create safer workplaces and protect the health of all workers.
