2021-07-28View Original

Thread Content

1. Leak prevention: During summer production, if raw materials leak, it not only leads to environmental hazards and material losses but also poses a risk of poisoning for workers, especially when the leaked materials splash directly on them, increasing the danger even further. To prevent leaks, the following measures should be taken: 1. Operate with care: When disassembling or connecting material transfer valves and pipelines, pay close attention to the opening and closing state of the valves to avoid leaks caused by material escaping outside or by pressure buildup leading to spraying and subsequent leaks. 2. Some glass viewports, vent valves, level gauges, and control valves must be equipped with protective measures to prevent leaks resulting from collisions, incorrect operation, or damage. 3. The liquid level in each storage tank must be strictly kept below the standard (warning) level; storing above this level must be avoided to prevent overflow. At the same time, it is essential to regularly check and verify the accuracy of the level gauges in each storage tank, to avoid false levels or misleading indications that could lead to overfilling. 2 Fire prevention 1. In summer, it is hot with high temperatures. In the chemical production area, there are many flammable, explosive, and volatile raw materials. For example, ethanol, dichloroethane, etc., have low boiling points and are all volatile substances. It evaporates more rapidly in hot summers, and it can easily reach its ignition point and explosive limit in areas with high concentrations. 2. In summer, it is hot and dry with an increase in thunderstorms; fire prevention should be given top priority. Staff on the post must operate carefully and strictly prevent the occurrence of the three types of violations ; The on-duty inspectors should conduct thorough checks, and any signs of fire hazards or violations of rules and regulations must be dealt with seriously. 3. Explosion prevention: Many chemical raw materials are flammable, explosive, and toxic, and their reactions are complex; therefore, it is essential to take proper explosion prevention measures during the summer. 1. Strengthen the safety management and monitoring of safety valves, explosion-proof membranes, distillation systems, etc. Conduct regular inspections, tests, or replacements to keep it in good and effective working condition at all times. 2. Operate with caution; it is strictly prohibited to violate operating procedures or carry out work beyond specified limits. 3. Strengthen fire source management. It is strictly prohibited to bring sources of fire into the production area, and unauthorized hot work must be avoided at all costs. 4. It is strictly prohibited to store two substances that are prone to reacting together. Once the management of warehouses and workshops is strengthened, it is strictly prohibited to store items that should not or cannot be kept together. 4. Poison prevention: Many raw materials used in chemical enterprises are toxic or corrosive; accidental contact with or inhalation of these toxic substances can easily lead to poisoning or physical damage. In summer, sweating is common, and toxic and harmful substances can easily penetrate the body through human pores, causing poisoning. So how should we take precautions in summer? 1. Prevent poisoning during maintenance work; when repairing pipes and equipment that come into contact with toxic and harmful substances, it is essential to wear protective gear such as gas masks, protective gloves, and safety glasses. 2. Operators in each position must carry out their tasks carefully, and duty personnel as well as section chiefs should conduct regular inspections; poisoning caused by materials splashing onto or flowing directly onto the operators is strictly prohibited. Pay attention to the sequence of operations; one person should handle the critical tasks while another oversees them. 3. When loading and unloading materials, be sure to secure the connections tightly. Check that the inlet and outlet valves are functioning properly before starting the transfer pump. It is strictly prohibited to reverse the order of operations, as this could lead to localized pressure buildup, causing materials to spill and resulting in accidents such as poisoning. 4. Relevant departments should strengthen routine inspections to eliminate all instances of leaks and losses. In particular, strengthen inspections and precautions regarding the weak points in equipment and facilities. For example: checking the liquid levels in the storage tanks in various tank areas as well as the venting systems, to prevent leaks that could lead to human poisoning. 5 Prevent overheating: The weather is hot with high temperatures. In some exothermic reaction processes, it is difficult to cool down and control the temperature; overheating can occur easily. Without strict controls, safety accidents are likely to happen. At the same time, due to improper operation, overheating and overpressure can easily occur, ultimately leading to accidents. 1. Operators in various positions must carry out their tasks in strict accordance with the \"six strict requirements\" for operators, exercising strict control over operations. Operating beyond the permitted temperature limits is strictly prohibited; in cases where temperature control becomes difficult, emergency measures such as reducing temperature, lowering output, or shutting down the equipment immediately should be taken. 2. The temperature control for material storage and the transfer of materials at various workstations must also be within standard ranges. 3. Attention must also be paid to temperature when loading and unloading materials; in particular, it should not be done in areas with high temperatures or direct sunlight. One should stand in the upwind direction while performing these tasks to prevent poisoning or other hazards. 6. Low-boiling-point and volatile substances such as antistatic ethanol and dichloroethane become even more volatile in summer. Coupled with the frequent thunderstorms during this season, it is particularly important to prevent accidents such as fires and explosions caused by static electricity involving these hazardous chemicals. 7. Protection against electric shock: In hot weather, the temperature inside the power distribution room is relatively high, and factors such as damaged, aged, or malfunctioning electrical equipment can affect production. While carrying out regular inspections and maintenance tasks, electricians must take strict precautions, implement proper safeguards, and exercise close supervision; there should be no room for carelessness or reliance on luck. 1. Electricians must wear personal protective equipment as required; they must wear insulating shoes and insulating gloves during maintenance. There should be one person performing the maintenance while another supervises, with protective and preventive measures being taken at all times. 2. Before performing maintenance on electrical instruments and operating equipment, the power must be turned off first, and a “Do Not Close” sign must be placed. The work can only be carried out under supervision by someone present. It is strictly prohibited to carry out work or give instructions in violation of regulations in order to save time or meet deadlines. 3. Do not tamper with any energized equipment such as electrical appliances, instruments, or buttons that are not under your responsibility. In the event of a malfunction in equipment under your care, you must report it immediately and notify professional maintenance personnel for repairs. It is strictly prohibited to touch, disassemble, or repair such equipment on your own. 4. The repair and maintenance of electrical equipment and instruments must be carried out in accordance with specifications. It is strictly prohibited to substitute non-standard or incompatible parts as a makeshift solution. It is also strictly prohibited for electrical instruments and meters operating beyond their temperature, load, or service life limits to continue functioning while faulty. 5. Strengthen duty inspections; ensure thoroughness, meticulousness, and standardization during duty hours, and keep proper shift handover records. During extreme weather conditions, it is even more necessary to strengthen the inspection of rain and lightning protection facilities for electrical equipment and instruments in various workshops, to prevent disruptions to production or electric shock accidents. 8. Prevention of heatstroke: During summer production, great care must be taken to prevent heatstroke: 1. Workers in positions with heavy workloads must pay attention to resting; they should not work excessively for long periods just to meet deadlines or accelerate progress. 2. Since jobs that require a lot of physical effort lead to excessive sweating, it is necessary to drink plenty of water, especially beverages that help prevent heat exhaustion. At the same time, go to a shaded place during breaks. 3. Do not assign too much work; help each other to complete it together. Once heatstroke is detected among employees, immediate rescue measures should be taken, and medications for preventing heatstroke should be on hand as a precaution. 4. When feeling unwell, experiencing dizziness, general weakness, or vomiting and discomfort, stop working immediately and take emergency measures right away. 9. Burn prevention: In the hot summer weather, employees wear light clothing, and slight carelessness can easily lead to various types of injuries. 1. Prevent hot intermediate materials, heating media, etc. from splashing, flowing, or dripping onto the body. These materials can not only cause burns but also lead to poisoning. For example: heat transfer oil, steam, steam condensate, or hot water at 80°C, as well as intermediate materials with higher temperatures. When connecting these materials with pipelines, it is essential to secure them tightly to prevent them from falling off. 2. During the production process, it is strictly prohibited to touch operating equipment or facilities with the body, bare hands, tools, or feet. Women operating rotating equipment should tie up their hair to prevent it from getting accidentally caught in the machinery. 3. Before maintaining operating equipment and facilities, it is necessary to first cut off the power and hang up warning signs. Then, remove belts such as V-belts and conveyor belts before proceeding with the maintenance work. At the same time, it is important to coordinate well with the personnel on duty to prevent accidents from occurring due to lack of awareness. 4. Employees are strictly prohibited from engaging in illegal operations, violating labor discipline or safety procedures – that is, committing the \"three types of violations\" – which could lead to accidents such as collisions and falls. 5. Safety helmets must be worn when conducting inspections and working within the production area. For work at heights, a height work permit is required, and a safety belt must be used.
