Chapter I
GENERAL REGULATIONS
Article 1. Scope of regulation
This Regulation deals with the Risk Acceptance Criteria applicable to humans used for the quantitative risk assessment ofpetroleum, oil and petrol, chemical, thermal power activities that take place within the territory, exclusive economic zones, and continental shelves of the Socialist Republic of Vietnam.
Article 2. Subjects of application
This Regulation is applicable to the organizations and individuals that engage in the petroleum, oil and petrol, chemicals, thermal power activities.
Article 3. Interpretation of terms
The terms in this Regulation are construed as follows:
1. Risk: Is the combination of possibility of emergencies, accidents, and their consequences.
2. Level of risk: Is the possibility of fatalities due to the risks in the activities or constructions. For instances, the level 1.00E-0 of risk is the possibility of 01 fatality per year.
3. Risk assessment: is the identification and determination of potential risks as the basis for providing measures to minimize the risk as low as reasonably practicable.
4. Quantitative risk assessment: Is the analysis and calculation of the frequency and consequences of emergencies based on the methods and data that have been announced and accredited worldwide.
5. Acceptable level of risk is the level of risk that is acceptable to humans.
6. Petroleum, oil and petrol, chemical, and thermal power activities and the activities relevant to the exploration, extraction, construction, operation, renovation, and decommissioning petroleum, oil and petrol, chemical, and thermal power constructions.
7. People in Group I: are the people working regularly at the construction.
8. People in Group II: Are the people not working at the construction that are irregularly present at the construction such as inspectorates or visitors…
9. People in Group III: Are the people not working at the construction that are present around the construction.
10. Broadly acceptable level of risk: is the level or risk that is so low procedure the risk does not affect the safety.
11. The failure of rescue and escape functions of offshore petroleum constructions : in an emergency, the instruments designed for the rescue and escape of an offshore petroleum construction (the emergency exit, the temporary shelter, the vehicles for leaving the construction, the integrity of the structure) must be sustained. These instruments must be sustained long enough for humans to leave the dangerous area, and safely leave the construction.
In an emergency, an instrument is considered “in failure" when it is not used as designed or not intact over a certain period of time.

ANNEX
QUANTITATIVE RISK ASSESSMENT METHODOLOGY
I. THE QUANTITATIVE RISK ASSESSMENT PROCESS
The quantitative risk assessment is developed and used as an instrument for assisting the safety management of the organizations and individuals that engage in petroleum, oil and petrol, chemical, and thermal power activities.The quantitative risk assessment process is demonstrated in Picture 1.
Picture 1. Quantitative risk assessment process
II. THE ORDER OF QUANTITATIVE RISK ASSESSMENT
1. Collecting data
This is a very important step in risk assessment and analysis which ensures the results that reflect the actual levels of risk caused by the technological system. The information, figures, and documents to be collected:
- The description of the construction and the operation conditions of the technological system;
- The environment and arrangement of the surroundings;
- The existing safety measures for preventing and avoiding accidents/emergencies.
2. Identifying risks
Based on the survey and collected data, the emergencies, accidents, and their consequences related to the construction shall be identified and determined. This process combines the experience from the previous researches, the knowledge about accidents in the world, and the assessments of experienced analysts.
3. Determining typical emergencies
Based on the list of possible hazards to the construction, the experience of accidents in the world, the types of emergencies shall be selected and taken into risk analysis.
4. Calculating frequency of emergencies
The frequency of each emergency is determined from the original frequency and the existing data at the site. The frequency of each emergency is determined and calculated by specialized software.
5. Consequence modeling
The consequence model helps calculate the seriousness of the consequences caused by the emergency, and their impact on humans. The consequences of each emergency is determined and modeled by specialized software.
6. Calculating risks
Based on the analysis results of the frequency and consequence modeling of each emergency, the quantitative levels of risk caused by the emergencies as well as the risk to the entire construction shall be calculated.The risk calculation result is expressed in the quantities of risk to an individual and risk to a group of people (group III).
7. The risk management measures
The results shall be compared to the standards, and appropriate suggestions shall be given in order to control and minimize the risk as low as reasonably practicable (ALARP principle)
III.The rules for selecting an acceptable level of risk
The acceptable level of risk shall be expressed according to the ALARP principle. The ALARP standard may be illustrated in an inverted triangle in Picture 2. The lower line is the acceptable level of risk, and the upper line is the unacceptable level of risk. The levels of risk increases from low to high based on the increasing triangle area. The upper part of the triangle expresses high risk, the lower part expresses low risk. If the risk lies below the acceptable level, no improvement is necessary apart from keeping the operation conformable with the industrial safety regulations. On the other hand, if the risk is higher than the acceptable level, it is necessary to consider the minimizing measures. Thus, we need to balance the expenditure on the minimization with the benefits of the safety enhancement. When the expenditure is reasonable, the minimizing measures may be taken. On the contrary, if the expenditure is too high, the implementation of such measures are not practicable. If the risk is too high and lies above the unacceptable level, the only way to minimize the risk is to shut down. Thus, the distance between these two level is called ALARP zone.
