Which of the measures specified in Document No. 116 issued by the State Administration of Work Safety has your organization implemented?

Isn’t a 116 file just a file that, if not executed, will result in the closure? How can it not be executed?

Conduct IPF analysis and prepare the report, to be completed by the end of the year.

The idea is ideal, but reality is bleak. Pushing, pulling, forcing someone to walk – is it really necessary to walk? Let’s see

IPF analysis report? I’m not familiar with it. Could you provide a detailed explanation? I have heard of things like Hazop analysis

HAZOP is a Hazard and Operability Analysis that identifies potential operational abnormalities that may occur during operation, as well as the risks they might pose. It is necessary to analyze the existing protection/reduction barriers, and determine whether the risk is acceptable based on the acceptable level of risk, as well as whether design changes are required to eliminate the risk. HAZOP is just a few keywords that guide the analysis of potential operational abnormalities. Recommendations need to be provided along with the analysis of the protective layer. IPF analysis determines the accident scenarios that can be prevented by each safety function based on the logic of the SIS system, and analyzes the existing risks. Existing protection and mitigation barriers are used to determine the SIL level, design the structure and requirements of the detection/actuation elements/SIS system, define the maintenance methods, identify the scenarios in which the protection functions operate, and determine the probability of failure. These all fall under the category of functional safety, and are within the scope of management of IEC61508 safety functions and IEC61511 safety instrumented systems. 61508 specifies the management of safety functions and can be applied in various fields such as automobiles, rail transit, and nuclear power. It outlines the full life cycle management of risks, from identification, assessment, allocation, design, implementation, maintenance, modification to cancellation. It specifies that the SIL levels range from 1 to 4. 61511 is applicable to the process industry and is specifically designed for the management of safety instrumented systems, specifying the specific requirements for IPF.
