Key points to consider in chemical safety operations (discussion)

Key points to be addressed in chemical safety operations: Chemical workers are the most direct participants in chemical production. The safety level of a company depends to a large extent on the overall safety skills of its chemical operators, as well as on how well the employees understand the key aspects related to their specific roles. For chemical production positions (teams), in order to ensure safe operations, the employees on these positions (teams) should at least master the following key points that they need to know and be able to apply. 1) The physical and chemical properties of the materials used in this position and team, as well as the possible consequences that may occur in case of impact or abnormal reactions, along with emergency response measures. 2) The toxicity of the materials used in this position and team, as well as the maximum allowable concentrations in the workplace, and the safety technical measures to be taken to prevent these concentrations from exceeding the allowed levels. 3) The technical specifications and requirements for raw materials and fuels in this position/crew, the possible consequences resulting from the presence of other impurities, and the measures to address them. 4) The potential dust explosion hazards at the work site and their preventive and control measures. 5) What are the non-removable flammable substances in and around the workplace for this position, and what preventive measures should be taken during production to prevent their combustion? 6) Various hazardous by-products that may arise during the production process, as well as the preventive measures to be taken to avoid their formation. 7) Consequences that may arise when one or more raw materials cannot be fed into the reaction vessel in a timely manner during continuous production, as well as preventive or corrective measures. 8) What is the stability of various materials (raw materials, products, semi-finished products) during storage? Do they tend to catch fire spontaneously, polymerize on their own, or decompose? What preventive or corrective measures need to be taken to avoid such phenomena? 9) What dust control, poison prevention, explosion protection, or fire-fighting facilities are currently in place at the work site, and what are the key points for their daily maintenance and use? 10) Various potential dangers that may arise from misoperations, the various consequences that can occur when process parameters approach the established upper and lower limits, and the preventive or corrective measures to be taken to avoid such situations. 11) What combustible or explosive mixtures may be generated when the production system is operating abnormally, and how to prevent them or handle them in an emergency. 12) What preventive measures should be taken for operations near the flash point? 13) What are the reaction speeds under normal and abnormal conditions, and how can abnormal phenomena such as abnormal temperatures, pressures, reactions, contamination by impurities, flow blockages, and leaks be prevented? Upon discovering the aforementioned phenomenon, what emergency measures need to be taken? 14) What consequences can occur when rotating equipment such as fans, pumps, and mixers fail, and what are the preventive and emergency response measures? 15) What are the consequences of blockages in operating equipment or pipelines, and how can they be prevented or dealt with urgently? 16) What kind of dangerous situation will arise inside the device in the event of a fire outside the production system, and how should it be dealt with urgently? 17) What are the safety devices for various equipment in this position, and what are the key points for their maintenance? 18) What materials may leak in the event of damage to the glass sight glasses, glass level gauges, various flange connections, and other devices at the work site, or if these connections are not secure? What are the emergency measures to take? 19) What consequences can arise when various level gauges, indicating instruments, recording devices, and other instruments used in production provide inaccurate readings or records? What are the preventive, corrective, or emergency measures available? 20) How to ensure the continued safe and stable operation of the production system when some instruments and meters in it fail? 21) What are the key points of various accident plans for this team and position, under what circumstances are these plans implemented, and what are the specific procedures for their implementation? Besides what has been mentioned above, do the sea friends have anything else to add?
Knowing something and actually doing it are two different things. People are the most unreliable; even if you are an excellent worker, factors such as your health or family situation can affect your judgment and thus impact your productivity. Therefore: 1. Strict safety management systems must be established ； 2. Reliable safety measures must be taken ； 3. Serious safety accident drills must be conducted ； 4. It is necessary to implement the safety production policies, objectives, and measures ； 5. All safety management rules and regulations must be strictly enforced. In fact, the most important thing is to ensure implementation and execution. It is often the case that people just shout slogans to meet inspections, while few actually carry out the requirements earnestly; this is the biggest hidden danger and the root cause of accidents.
In modern chemical plants, the degree of automation in electrical equipment and instruments is very high, and there is an increasing reliance on them. Emergency measures to ensure safe production in the event of failures in these electrical devices must be in place. In high-risk chemical industries, power supply safety is particularly important; therefore, power supply solutions such as dual-power supply systems are often employed. Additionally, safety measures to halt reactions in the event of a power outage must also be established.
