Summary: Inherently safe design measures are measures to make machinery safe, by
reducing risks relating to machinery and operators, through elimination of hazard sources and
reduction of risk (for details, see ISO 12100 2010/JIS B 9700 2013 6.2 Inherently Safe Design Measures)
List of inherently safe design measures
Consideration of geometrical factors Measures through shape and layout Mecha.-2
Consideration of physical aspects Measures to limit radiation from materials by reducing energy etc. Mecha.-4
T aking into account general technical knowledge of machine design Measures by applying technical specifications, such as material properties, processing, assembly method etc. -
Select appropriate technology Measures by using safe (inc. new) technology that does not incur hazards -
Applying principles of positive mechanical actions between components Measures to cause operations carried out by combination of machines to act on safety side -
Measures for installation stability taking account of weight distribution of machine itself, load fluctuations and Mecha.-1
Provisions for stability installation location etc. -
Provisions for maintainability Measures to secure necessary workspace for maintenance and to simplify handling Work3-8
Observing ergonomic principles
Measures to prevent mental or physical stress for user
Preventing electrical hazards Measures to prevent electric shock through protector on live parts/circuit breakers Ope.-4
Preventing pneumatic and hydraulic hazards
Applying inherently safe design measures to control systems Measures to prevent hazard when stability of pressure, restriction function on the maximum rating pressure or pressure -
is lost
Measures to prevent injury due to control malfunction or parts failure -
Minimizing probability of failure of safety functions Measures by selecting/using reliable and proven equipment -
Limiting exposure to hazards through reliability of equipment Measures to prevent failure by selecting/using highly reliable machine components -
Measures so that machine operation-related work need not be carried out in danger zones Basic-3
Limiting exposure to hazards through mechanization/automation of Measures so that work other than machine operation-related work need not be carried out in danger zones Basic-4
