Where do chemical accidents originate from? The Petrochemical Region looks forward to your participation

Safety is a red line, it is a lifeline. Every accident requires us to keep it firmly in mind and constantly sound the alarm for safety. As a chemical plant operator, one must pay close attention to every step of the operation, thinking carefully before taking action. Join the reply and discussion – let’s learn together, with safety always by our side! Registered Chemical Engineers – Experience Sharing Event titled “Learning from Others”. In 2017, there was an event related to coal chemical industry titled “My Technical Upgrades” (with generous rewards). Moderators and technical experts are being sought in various sections of the Registration and Chemical Engineering forum; substantial rewards are available – contact the forum owner directly!
Operators are very important; excellent operational skills can reduce a great deal of manual work as well as inspection and maintenance tasks carried out by on-site staff； Secondly, it enables emergency response and the detection of precursors to accidents.
If safety management is inadequate, even highly skilled operators may sometimes overlook things and make mistakes based on experience. Experience comes from daily work, while safety awareness is a manifestation of proper safety management. By establishing a set of systems for management, with a dual mechanism that operates both from top to bottom and from bottom to top, safety can be further ensured.
The equipment is advanced, with all interlocks in use, and the manufacturing process is also sophisticated. However, the technical skills of the operators and managers are low, preventing them from effectively managing the system; accidents are only a matter of time. Therefore, the unsafe behavior of personnel and the competence of managers are of critical importance
It’s still mostly due to human factors. The quality of managers is low, and the quality of operators is also low.
Unsafe human behavior, unsafe conditions of objects, environmental factors
For a chemical company, it is essential to ensure intrinsical safety; that is, even in the event of operator errors, there should be cascade protection mechanisms to prevent any problems from occurring. 1. Operating equipment and facilities in a faulty condition, as well as disabling the alarm and interlock systems without approval; having alarm systems for flammable and toxic gas leaks in an abnormal state; not activating the emergency shutdown system; inaccurate level gauges; uncalibrated safety valves; inaccurate pressure gauges; and clogged vent valves – all of these issues must be completely resolved, otherwise no matter how good the technical capabilities are, they will be of no use. 2. All personnel must complete training and work with valid certificates; the safety measures specified in the tickets for the eight types of operations must be followed. Giving orders that violate regulations or forcing others to work in dangerous conditions is strictly prohibited. Operations must be carried out in accordance with established procedures. There must be a plan for process handover, inspection after equipment repair, and confirmation before the system is put into use – all of these are aspects of human safety management.
Human factors account for a large proportion of safety accidents; violations always lead to serious consequences as a result of minor mistakes
Leadership gives priority to it, employees play their role, processes are scientific, equipment is advanced, measures are comprehensive, and supervision is thorough.
There is chaotic management; the boss only thinks about making money, ignoring safety, environmental protection, training, and so on…… That’s the key issue
