Background of the project
Pharmaceutical Manufacturing Industry refers to the process in which raw materials become new pharmaceutical products after physical or chemical changes, including the so-called Chinese and Western medicine manufacturing, veterinary medicines also include pharmaceutical raw materials and health materials. The pharmaceutical and pharmaceutical industry is a complex chemical industry with cumbersome processes and complex processes. Flammable substances are often produced. These flammable substances specifically refer to the explosive gas formed after mixing with air, which may be flammable gas, flammable liquid, flammable vapor, etc. The main dangerous gases that often appear in the pharmaceutical production process are: ammonia, chlorine, formaldehyde, sulfur dioxide, hydrogen sulfide, oxygen, VOCS, ozone, solvents, etc.
dangerous gas
The possibility of existence of methanol (CH3OH), ethanol (C2H6O), total volatile organic compounds (TVOC) and other gases in the workshops, laboratories and warehouses of large pharmaceutical factories. Methanol has low toxicity to the human body, and has anesthetic effects on the central nervous system; it has a special selective effect on the optic nerve and retina, causing lesions; it can cause metabolic acidosis. Ethanol is low toxicity, volatile, and is a central nervous system depressant. Long-term exposure to high concentrations of this product can cause irritation to the nose, eyes, and mucous membranes, as well as headache, dizziness, fatigue, irritability, tremor, nausea, etc. Long-term exposure to the skin can cause irritation. Causes dryness, scaling, chapping and dermatitis. TVOC can cause imbalance of the body's immune level, affect the function of the central nervous system, and cause dizziness, headache, drowsiness, weakness, chest tightness and other subjective symptoms; it may also affect the digestive system, such as loss of appetite, nausea, etc. In severe cases, it can damage the liver and hematopoietic system. Allergic reactions, etc.
According to the relevant regulations in the National Standard: "Occupational Exposure Limits for Hazardous Factors in the Workplace", methanol: PC-TWA: 25mg/m3 (17.5ppm), PC-STEL: 50mg/m3 (35ppm); ethanol: PC-TWA, 1900mg /m3 (911ppm), PC-STEL 2400mg/m3 (1151ppm); TVOC: PC-TWA 0.60mg/m3, PC-STEL no; PC-TWA: 8h working days and 40h working weeks specified by time as the weight Average allowable exposure concentration.
Program overview
In order to fully protect the environmental safety in the factory area, a toxic gas detection system should be set up to conduct real-time monitoring of workshops, laboratories, warehouses, etc. When a certain gas content exceeds the standard, timely measures should be taken to avoid danger.
