Scope
This document establishes the criteria to evaluate when whole body access exists in a machinery application and includes appropriate risk reduction measures to minimize or reduce associated risks. It provides a methodology to determine the selection of risk reduction measures when whole body access exists.
This document assumes separation distances have been applied according to ISO 13855 and ISO 13857.
Protection against the risks from hazards arising from emissions (e.g., the ejection of solid or fluid materials, radiation, electric arcs, heat, noise, fumes, gases) are not entirely covered by this document, although the application of the proposed risk reduction measures may minimize or reduce them. Protection against the risks from hazards arising from breaking of parts of the machine or gravity falls, are not covered by this document.
This document applies for safeguards used on machinery for the protection of persons 14 years and older.
Purpose
Machinery builder and integrators looking for guidance and direction relevant to the topic of whole body access must currently search many standards and directives to piece together a unified approach for reducing risks to operators. Even then, a number of identified gaps related to possible risk reduction measures exist. Furthermore, no known standard objectively describes the conditions under which whole body access exists, therefore resulting in a non-standardized approach to reducing risk across industry sectors.
The purpose of this proposal is to consolidate guidance related to defining whole body access situations, as well as standardizing the approach to selecting appropriate risk reduction measures. This type-B standard will provide designers with an overall framework and guidance for decisions during the development of machinery and machinery system to enable them to design machines that are safe for their intended use. It also provides a strategy for standards developers and will assist in the preparation of consistent and appropriate type-C standards.
