GB/T 41344.4-2022 Safety of machinery - Risk early-warning - Part 3: Classification
1 Scope
This document specifies the systematics process of risk early-warning, model determination, weight determination, determination of level of early-warning limit, input of monitoring value, risk value calculation, and output of level of early-warning, and gives an application example of the systematics process.
This document is applicable to the risk early-warning systematics related to the safety of machinery.

3 Terms and definitions
For the purposes of this standard, the following terms and definitions and those given in GB/T 30174-2013 and GB/T 41344.1-2022 apply.
3.1
danger zone; hazard zone
any space inside and/or around machinery that exposes personnel to hazards
[Source: GB/T 30174-2013, 2.27]
3.2
safety zone
space where personnel are not exposed to hazards
3.3
early-warning zone
space between the safety and hazard zones
3.4
abnormal behavior
action that violates regulations or does not conform to workflow
4 Process of early-warning systematics
The process of mechanical/machine early-warning systematics generally includes model determination, weight determination, determination of level of risk early-warning limit, input of monitoring value, risk value calculation, output of level of early-warning, etc., as shown in Figure 1. Design a risk value quantification calculation model that includes early-warning monitoring variables such as human, machine, environment based on actual application environments, determine its weights, and define levels of early-warning. Based on the monitoring values, calculate the risk value in real-time, determine the level of risk early-warning, and output it.
