May I ask if that evaluation company can calculate personal risk and social risk scores?

Risk analysis is very important in standardization, and it involves a wide range of specialized fields; for example, managers from various departments and workshops who are involved in areas such as processes, equipment, safety, environmental protection, site management, electrical systems, and instrumentation. The common evaluation methods include the following: 1) Job Hazard Analysis (JHA) ； 2) Safety Checklist Analysis (SCL) ； 3) Preliminary Hazard Analysis (PHA) ； 4) Hazard and Operability Analysis (HAZOP) ； 5) Failure Mode and Effects Analysis (FMEA) ； 6) Fault Tree Analysis (FTA) ； 7) Event Tree Analysis (ETA) ； 8) Methods such as Job Safety Analysis (LEC). 1. The criteria for assessing the likelihood of an event occurring are shown in the table below. Level Likelihood L Assessment Criteria: 5 – No preventive, monitoring, protective, or control measures are in place at the site; the occurrence of hazards cannot be detected (no monitoring system); or such accidents or events occur frequently under normal conditions. 4 The occurrence of the hazard cannot be detected; there is no monitoring system at the site, and no tests have been conducted. Alternatively, although there are control measures in place at the site, they are not effectively implemented or are inadequate. Or the hazard occurs frequently or under predicted conditions. 3 There are no protective measures (such as protective devices or personal protective equipment), or the operating procedures are not followed strictly, or the occurrence of hazards can be easily detected (with monitoring systems in place), or inspections have been conducted, or similar accidents or incidents have occurred in the past, or dangerous accidents or incidents occur under abnormal conditions. 2. Once hazards occur, they can be detected in a timely manner, and monitoring is carried out regularly; or there are preventive control measures in place that can be effectively implemented; or dangerous accidents or incidents have occurred occasionally in the past. 1. There are sufficient and effective measures for prevention, control, monitoring, and protection, or the employees have a high level of awareness regarding safety and hygiene; operational procedures are strictly followed, so accidents or incidents are highly unlikely to occur. 2. The severity of the consequences of an incident is indicated in the table below: Criteria for assessing the severity of incident consequences – Grade. Legal regulations and other requirements; financial losses (in ten thousand yuan); suspension of operations; impact on the company’s reputation. 5: Violation of laws, regulations, and standards; death >40; suspension of operation of some facilities (more than 2 sets) or equipment; significant international and domestic impact. 4: Potential violation of laws and regulations; loss of working capacity >25; suspension of operation of 2 sets of facilities or equipment; impact within the industry or province. 3: Non-compliance with the safety policies, procedures, and regulations set by higher-level companies or the industry; amputations, fractures, hearing loss, chronic diseases >9; suspension of operation of 1 set of facilities or equipment; regional impact. 2: Non-compliance with the company’s own safety procedures and regulations; minor injuries, occasional discomfort

Both the individual risk curve and the F-N curve are calculated using software; the main types of such software available in China at present are SAFETI and RISKCURVES. These software solutions are not inexpensive; those that are available are generally used by engineering companies affiliated with Sinopec and CNPC, as well as foreign consulting firms.
