ISO standard to protect machine operators from injury and fatal accidents

ISO 12100 standard on risk assessment and risk reduction for machinery protects operators better and helps designers and manufacturers reduce safety hazards.

Accidents involving machinery incur high costs, both in human terms and also economic and societal ones. Although calculating an exact figure is unrealistic, studies have shown that for a single accident the total cost to the individual and to society can be as high as USD 1 million.  

With ISO 12100:2010, Safety of machinery – General principles for design – Risk assessment and risk reduction, designers are able to identify risks during the design stage of machine production and hence reduce the risk of future accidents.

The risk assessment guidelines provided in the standard are presented as a series of logical steps. These help designers to systematically determine the limits of the machinery; identify risks of hazards like crushing, cutting, electric shock or fatigue; and estimate potential dangers ranging from machine failure to human error.

The information obtained through this process allows producers to determine whether a machine is sufficiently safe or not. In the eventual case that the machine is found to be unsafe, this information will be valuable for the subsequent risk reduction stage. The process would then be repeated until the machine is established as adequately safe for use.

ISO 12100 is a tool that is showing itself highly effective to help bring down the number of accidents by defining the methodology used when designing the machines, and laying out measures to prevent them occurring. Its use saves individuals from injury, reduces financial and human costs to society and, at the same time, ensures people the safety and comfort of a user-friendly environment.

By providing a best practice framework at the international level, ISO 12100 helps eliminate technical barriers to trade while maintaining the safety and health of users of machinery, in line with requirements of national legislation of different countries around the world.

ISO 12100:2010 has replaced ISO 12100-1:2003, ISO 12100-2:2003 and ISO 14121-1:2007. It is intended to be used as a basis for the preparation of type-B (generic safety standards) dealing with one safety aspect or one type of safeguard that can be used across a wide range of machinery or type-C safety standards (machine safety standards) dealing with detailed safety requirements for a particular machine or group of machines.

ISO 12100:2010, Safety of machinery – General principles for design – Risk assessment and risk reduction, was developed by ISO/TC 199, Safety of machinery, which works together with industry, health and safety bodies, authorities, unions, employer’s associations and international organizations such as the International Labour Organization (ILO) and the World Health Organization (WHO) to develop standards that reduce the risks of injury from machinery at home, work and during leisure activities.
