3General requirements for risk assessment
3.1
Information validity
GB/T22760—2020
Before risk assessment, relevant information should be widely collected. During the assessment process, relevant information should be continuously investigated and supplemented, and the information should be ensured to be true, reliable and timely.
3.2 Combination of qualitative and quantitative methods
Scientific and effective risk assessment methods should be selected according to the types and characteristics of consumer product safety hazards (sources). When appropriate data is available, quantitative methods of risk assessment should be given priority. 3 Throughout the life cycle of consumer products
3.3
Different risk assessment methods should be used according to the characteristics of each stage of the life cycle of consumer products. 3.4 Comprehensive assessment
The level of scientific, technological, economic and knowledge development should be comprehensively considered to determine the hazards (sources), tolerable risks and risk levels. Repeated reviews should be conducted as needed to determine tolerable risks.
4 Procedures and Contents of Risk Assessment
4.1 Procedures
The general procedures of risk assessment include: pre-assessment preparation, hazard identification, risk estimation, risk evaluation and other steps. The procedures of consumer product safety risk assessment are shown in Figure 1. The risk assessment process of physical hazards, chemical hazards and biological hazards of consumer products can be refined on the basis of this process, see Appendix A and Appendix B. Start

Content
4.2.1
Preparation before assessment
Preparation before risk assessment may include:
a) Determine the use environment, service life, user population, usage quantity, etc. of the target consumer product; b)
Based on relevant domestic and international laws, regulations, standards, literature, expert experience and other information, and taking into account the influencing factors of social and economic development levels, determine the tolerable risk of consumer product safety risk assessment. 4.2.2 Hazard Identification
Identify the hazards (sources) of consumer products during normal use and reasonably foreseeable misuse. Appendix C gives the types of hazards (sources).
The main ways to identify hazards include:
Published regulations and standards;
a)
Scientific and technological information (product quality and safety design requirements in various industries); b)
c)
Accident reports;
d)Consumer complaints;
Media;
e)
Experiments and tests;
f)
g)
Expert opinions, etc.
4.2.3 Risk Estimation
4.2.3.1
Overview
After hazard identification, the risk should be estimated based on the hazard (source), considering the hazardous situation, the severity of the harm and the possibility of the harm. For specific methods of risk estimation, see Appendix A, and for types of injury, see Appendix D. 4.2.3.2
Content
-Generally speaking, risk estimation may include the following: a) Severity of injury The degree of injury to the human body caused by consumer products can generally be divided into four levels, namely, very serious, serious, general and weak, as shown in Table 1. Generally, the grading criteria are the scope of injury, harm to personal health, property loss, induced secondary harm, and preventability.

Characteristic description
Causes catastrophic injury. This type of injury can cause death, physical disability, or cause major property losses, etc. It can cause irreversible human injuries (such as scars, etc.) or cause major property losses. This type of injury should be treated in the emergency room or hospitalized, or the property losses caused have a certain impact on family life. The injury can be treated in the outpatient clinic, or it can cause minor property losses. The impact of this type of injury on the subsequent financial expenses of the human body or family is generally
The injury can be treated at home without medical treatment, but it causes a certain degree of discomfort to the human body and does not cause obvious property losses. This type of injury has a relatively mild impact on human health and property. GB/T22760—2020
b) The possibility of injury A specific hazardous situation corresponding to the injury can be divided into several stages, each of which corresponds to a potential stage possibility that causes the injury to occur, and the possibilities of each stage constitute the possibility of the injury. The information required to calculate the possibility of injury can be obtained through the following channels: relevant historical data;
1)
2)
Experimental simulation;
3)
Expert judgment, etc.
The possibility of injury can generally be divided into eight types, see Table 2, Table 2

Possibility type of injury
Characteristic description
The possibility of an injury incident is extremely high, and injury incidents will occur repeatedly under any circumstances
There is a certain possibility of an injury incident occurring, which is not a small probability The event has a certain probability of occurrence of an injury event, and is a low-probability event. A few injury events will occur, but the probability is small. A few injury events will occur, but the probability is extremely small. They will not occur, but they may occur in very rare specific circumstances. In any case, an injury event will not occur. Note: The specific value of the injury probability level in the table can be determined according to the actual situation. Risk estimation method
4.2.3.3
It is necessary to consider the characteristics of consumer products and hazards (sources), and scientifically select appropriate risk estimation methods in combination with the product life cycle, see Appendix A.
4.2.4 Risk assessment
For a certain hazard, the risk level of the consumer product can be estimated based on the possibility of the injury caused by it and the degree of injury. The matrix method can generally be used to divide the risk level of consumer product hazards, see Appendix E. If a consumer product has two or more hazards, a risk assessment should be conducted for each hazard separately, and the highest risk level of various hazards should be used as the safety risk level of the consumer product. 4.2.5 Risk Assessment Documents
