Which protective equipment should you choose for working in different chemical processing environments

Thread Content

The chemical industry has always been a type of industry with an extremely high level of risk. Relevant professionals are generally required to strictly adhere to safety standards as well as the company’s safety production regulations. Such strict management is actually a guarantee for an individual’s life safety. Do you know how many types of workplaces there are in the chemical industry? Do you know how to protect yourself in different types of production tasks? http://p2.itc.cn/images01/20200807/8e361acf05664d2587c16822c2b2160b.png Work involving toxic and harmful gases http://p2.itc.cn/images01/20200807/afa75f7d9ced480fb633bf9ba957e046.png Jobs in which substances are in gaseous or vapor form at normal temperature and pressure, and inhaling these substances through the respiratory tract can cause toxicity; this includes irritating gases and asphyxiating gases, which can lead to poisoning and asphyxiation incidents. Appropriate protective equipment: A01 work hat, B01 dust mask, B02-B03 gas masks, B04 air respirator, E02 chemical-resistant gloves, G04 chemical protective suit. Work involving liquid poisons refers to tasks carried out in workplaces where there are liquid substances that can adhere to the skin and clothing, and which can cause poisoning through skin absorption or damage to the skin. Appropriate protective equipment: A01 work hat, B01 dust mask, B02-B03 gas masks, B04 air respirator, C05 goggles/masks for protection against corrosive liquids, E02 gloves for chemical protection, G04 chemical protective clothing. Work involving solid poisons: tasks that involve exposure to solid poisons. This includes jobs in the workplace where substances are in an aerosol state at normal temperature and pressure, and inhaling such substances through the respiratory tract can cause harm to the human body; as well as jobs involving solid substances that can enter the body through the skin and have toxic effects. Appropriate protective equipment: A01 work cloth, A03 cape hat, B01 dust mask, B02-B03 gas masks, B04 air respirator, E02 chemical-resistant gloves, G04 chemical protective suit, G05 dust-proof suit. Dust-related work: http://p1.itc.cn/images01/20200807/92442afb4ad04433ba648b9601fe0d0f.png In this type of work, workers are exposed to productive dusts for extended periods of time; when they inhale certain dusts in concentrations that exceed specific limits, it can lead to diffuse fibrotic changes in the lungs, affecting the function of the respiratory tract and other organs. Appropriate protective equipment: A01 work cap, A03 shoulder mask, B01 dust mask, G05 dust suit. Work in areas with flammable dusts: Work in workplaces where dusts of flammable solid substances exist at normal temperature and pressure. Tasks involving exposure to flammable chemical dusts such as aluminum and magnesium powder. Appropriate protective equipment: A01 work hat, A03 shoulder cape, B01 dust mask, B04 air respirator, E03 anti-static gloves, F06 anti-static shoes, G02 anti-static suit, G03 flame-retardant protective suit, G05 dust-proof suit. Working in flammable and explosive areas can lead to fire accidents as the uncontrolled combustion of such materials occurs. Appropriate protective equipment: B01 dust mask, B02-B03 gas masks, B04 air respirators, E03 anti-static gloves, F06 anti-static shoes, G02 anti-static clothing, G03 flame-retardant protective clothing, G04 chemical protective clothing, G05 dust-proof clothing. High-temperature work: http://p6.itc.cn/images01/20200807/0da6048eeb1e47d4bf22be032ce73aec.png Refers to work activities in which the average WBGT index (wet-bulb black-ball temperature) at the workplace is ≥25 during the production process. Burns to the human body caused by hot liquids and gases, burns resulting from contact with hot solids, burns inflicted by flames, and damage to the body due to the thermal radiation from hot sources. Appropriate protective equipment: A02 safety helmet, C04 goggles or face shield protecting against strong light and ultraviolet (infrared) rays, E07 heat-resistant gloves, F05 heat-resistant and flame-retardant shoes, G12 heat-resistant clothing. Work in high-light conditions: work involving strong light sources or those that generate intense infrared and ultraviolet radiation. Such as arc light, arc welding, and furnace operations. Appropriate protective equipment: C04 goggles or face shield with protection against strong light and ultraviolet (infrared) rays, C06 welding mask, E09 welding gloves, F10 welding protective shoes, G08 welding protective suit, G12 heat-insulating suit. Work involving ionizing radiation: http://p5.itc.cn/images01/20200807/c712e457649040fea41b67c8fdcf0f0c.png Refers to work in which workers are exposed to ionizing radiations such as X-rays, gamma rays, alpha rays, beta rays, and neutrons, with radiation doses exceeding the standard levels. Appropriate protective equipment: C03 radiation-proof goggles, E05 radiation-proof gloves, G10 radiation-proof suit. Jobs involving exposure to non-ionizing radiation, such as microwave radiation, ultra-high frequency radiation, high-frequency electromagnetic fields, power-frequency electric fields, infrared rays, ultraviolet rays, lasers, and other types of electromagnetic radiation. Appropriate protective equipment: C04 goggles or face shield with protection against strong light and ultraviolet (infrared) rays. Working in enclosed spaces: http://p8.itc.cn/images01/20200807/90c70712caed45e5a76130f56913da21.png It refers to working in areas where air circulation is poor, including situations where there is a lack of oxygen – that is, the oxygen concentration in the air is less than 18% – as well as environments with excessive levels of toxic gases and substances, and where such conditions cannot be eliminated. Appropriate protective equipment: A02 safety helmet, B03 long-tube gas mask, B04 air respirator, E02 chemical-resistant gloves, G04 chemical protective suit. Corrosive operations: http://p4.itc.cn/images01/20200807/98cecf5e444e4c58b0599d456c20aca9.png Operations that involve the production or use of corrosive substances. For example, operations involving the production or use of sulfuric acid, hydrochloric acid, nitric acid, hydrofluoric acid, liquid strong bases, solid strong bases, potassium dichromate, potassium permanganate, etc. Appropriate protective equipment: A01 work hat, C05 corrosion-resistant goggles/mask, E04 acid- and alkali-resistant gloves, F07 acid- and alkali-resistant shoes, G07 acid- and alkali-resistant suit. All professionals working in the chemical industry must choose appropriate protective equipment based on the working conditions in their respective environments. Personal protective equipment must be worn properly at work. Before entering the work area, one should check what is being worn and count the protective devices on one’s body; if anything is missing, it should be added immediately. Only by wearing all the necessary protective equipment can one enter the work environment to carry out tasks. Only by being careful can we protect our own lives!
