3 Terms and definitions
For the purposes of this document, the terms and definitions given in GB/T 30174-2013 and the following apply.
3.1
risk early-warning
process of predicting the hazard status (3.9) that may be triggered by human, machine, environment and their combined effects and giving warning by level, while taking corresponding measures in a timely manner to achieve the safety status (3.8)
Note 1: In general, risk early-warning is achieved by establishing a risk early-warning system.
Note 2: See Annex A for risk early-warning variables and their relationships.
3.2
risk early-warning system
system composed of software and hardware, which avoids the occurrence of hazard status (3.9) to the maximum extent through online data monitoring and evaluation of human, machine, environment and their combined effects, predicting the development trend of risks, giving a warning to possible unsafety status by level, and taking corresponding preventive measures in a timely manner
3.3
risk value
numerical value characterizing the severity of the risk obtained by quantitative calculation methods
3.4
early-warning monitoring
process of collecting information and operation data related to human, machine, environment and other variables by monitoring means, operating and analyzing them, and outputting them for calculating risk values
3.5
level of early-warning
level of risk divided by calculation result of risk value
3.6
early-warning systematics
process of determining the level of early-warning by risk value
3.7
early-warning measures
means and methods to reduce risks by level of early-warning
3.8
safety status
status where risks such as personal injury, property loss or damage to the working environment that may be caused by human, machine, environment and their combined effects are within acceptable ranges
3.9
hazard status
status where risks such as personal injury, property loss or damage to the working environment that may be caused by human, machine, environment and their combined effects are within an unacceptable range
4 Basic principles
The principles to be followed in implementing risk early-warning of machinery/machine include, but are not limited to:
——Targeting major hazards identified in the risk assessment, and hazards considered to require early-warning;
——Considering human, machine, environment and their combined effects;
——Compatibility with machine-related systems;
——Reliability;
