ABSTRACT
ISO 12100 details the requirements for a manufacturer's risk assessment to ensure machinery safety. The main steps in machinery risk assessment are establishing the context, determination of limits of machinery, hazard identification, risk estimation and risk evaluation. The results of the risk assessment are applied as decision-making support for risk reduction. The purpose of determining the limits of the machinery is to become familiar with the machinery to be assessed and to describe the system in a reasonable way for further assessment. Determination of the limits of the machinery must consider all phases of machinery life related to people, other machines, and the environment of the machines being evaluated. ISO 12100 states that four factors must be considered when reducing risk: the safety of the machine, the ability of the machine to perform its function, the usability of the machine, and the manufacturing, and operational dismantling costs of the machine.
