What knowledge should frontline workers in chemical plants have?

  1. Develop good operational behavior


(1) Routine inspection before operation The mechanical equipment must always be kept in normal operation. Routine inspections of machinery and equipment are carried out every day before work.



If any abnormal situation is found, the laborer should notify the management personnel in time, and can work only after maintenance and confirmation of safety.


(2) Firmly grasp the signal contact When more than two people work together, sometimes it is necessary to stipulate the contact signal and operate according to the signal.



For positions with contact signals, workers should keep in mind the specified signals, and start work after confirming and clarifying the meaning of the signals.


(3) Strictly abide by the operating procedures Simplifying and omitting the prescribed operating procedures for fear of trouble often lead to many accidents. Therefore, workers should strictly abide by the operating procedures.


  • In the case of unconventional operations, it should be reported in time. When product deformation occurs in the production line, or when a small fault occurs, some operations that are not specified in the operating procedures (ie unconventional operations) need to be carried out, such as debugging the machine, overhauling, oiling, etc. , should be reported to management in a timely manner.


  1. Absolutely prohibited unsafe operation behavior:



1) The operation of machinery and equipment, the method of picking and placing items are incorrect, and the support of objects is not firm.


2) Approaching or entering a dangerous place, such as a running machine or a lifted cargo.


3) Cleaning, refueling or overhauling mechanical devices that are running, energized or heated.


4) Start the machine suddenly, move the vehicle, object or proceed to the next step without giving a signal or confirming the safety.


5) Improper selection of mechanical devices, improper use or defects.


6) Leave the running machine and put the machine or material in an unsafe state or place.


7) The act of removing the safety device, or making the safety device ineffective.


8) Jumping on, off, or working with hands instead of prescribed tools from vehicles or machines.


9) Do not use personal protective equipment, or use it improperly, or wear it unsafely.


10) Feel free to touch unknown chemicals.


11) Hastily entered a confined space.


  • Rescue in the event of an accident.


  1. How to quickly identify the source of danger at work?



Hidden dangers refer to hidden calamities, that is, hidden or hidden dangers or disasters.


Accident hidden danger generally refers to the unsafe behavior of people, unsafe state of things and management defects that can lead to accidents in the production system.


  1. What are the unsafe behaviors of people?



There are 11 main categories, which are also the main direct cause of production safety accidents.


1) Ignoring safety, ignoring warnings, operating errors.


2) Man-made safety device failure.


3) Using unsafe equipment.


4) Operate by hand instead of tools.


5) Improper storage of objects.


6) Venturing into dangerous places.


7) Climbing or sitting in an unsafe position.


8) Interfering and distracting behavior.


9) Neglect or fail to use individual labor protection articles and appliances.


10) Unsafe attire. Baijia Management


  • Mishandling and mishandling of flammable, explosive and other dangerous goods.
