0Introduction
This standard specifies the principles for a consistent systematic procedure for risk assessment (see Chapter 6 of GB/T 15706.1-1995).
This standard gives guidance for decisions during the design of machinery (see 3.11 of GB/T 15706.1-1995) and will assist in the preparation of consistent and appropriate safety requirements in Type-B and Type-C standards in order to comply with the essential safety requirements specified in GB/T 15706.2.
It is recommended that this standard is incorporated in training courses and manuals to give basic instruction on design methods.
1 Scope
This standard describes the procedure known as risk assessment by which the knowledge and experience of the design, use, incidents, accidents and harm related to machinery is brought together in order to assess the risks during all phases of the life of the machinery.
This standard gives guidance on the information required to allow risk assessment to be carried out. Procedures are described for identifying hazards and estimating and evaluating risk. The purpose of the standard is to provide advice for decisions to be made on the safety of machinery and the type of documentation required to verify the risk assessment carried out.
This standard is not intended to provide a detailed account of methods for analysing hazards and estimating risks as this is dealt with elsewhere (e.g. text books and other reference documents).
