How to conduct a hazard analysis
Thread Content
As the title suggests, how can we conduct a hazard analysis of factories? What are the main hazards in chemical plants? High temperature, low temperature, electric shock, asphyxiation, mechanical injury, pressure release, noise, slips and falls, etc.? What other potential hazards are there?
For the hazard factor analysis of a chemical plant, it is recommended to first separate and analyze different operating sections or units; this is the first step that needs to be taken. The second step involves categorizing the identified hazard factors; it is recommended to proceed from the following aspects: 1. Identifying hazards related to the operation and malfunction of processes and equipment, using methods such as Hazop and PHP. There are many such analysis methods, and further research can be conducted by consulting relevant materials. 2. Identifying hazard sources that do not comply with laws, regulations, and other requirements. 3. Conducting surveys among all employees to identify hazard sources associated with various occupational activities and facilities. 4. Identifying hazard factors related to productive (as well as non-productive) activities. 5. Identifying hazard sources resulting from malfunctions in other activities and facilities (for those issues that cannot be resolved through the above methods). The third step requires conducting a risk assessment of the identified hazard factors; the LEC method is generally used for this purpose. Based on the assessed risks, OSH plans are developed and implemented for risk control. The fourth step involves making the identified hazards public and carrying out PDCA analysis to manage risks dynamically.
I. Identify hazardous factors； II. Determination, assessment, calculation of the level of hazard and risk ； III. Formulate measures to reduce and mitigate risks.
