Machine safety norms
The hierarchy of safety standards
Safety standards are structured systematically and hierarchically, to exclude different requirements for comparable hazards or similar risks or to avoid recurrences:
Type A safety standard
Fundamental standards related to general safety guidelines, referred to all machines in the same or a similar way. e. g. risk assessment.
Type B1 safety standard
Group of standards referred to general safety features. (e. g. safe distance, electrical safety, proximity speed/subjection).
Type B2 safety standard
Group of standards reffered to special protection devices that can be used with machines. (e. g. Emergency shutdown devices, mesh lights, two-hand control devices).
Type C safety standard
Group of standards of a specific industry which establish defined requirements and safety measures.
ISO 12100:2010 Definitions
Risk Assessment
Global process which involves an analysis and risk assessment, typically a team effort.
Adequate risk reduction
Risk reduction based on safety norms rather than technology application criteria.
Evaluation and risk reduction strategy (ISO 12100)
Characteristics and limitations of machinery
The main objective of this step is to have a clear definition of:
Machine’s functions (based on the machine)
Machinery can be described in terms of its different parts, mechanisms or functionalities based on its construction, such as:
The use of machinery can be described in terms of associated tasks to its designed use and the reasonable foreseeable misuse of the machinery.
