9 1 Introduction M+H has been requested by MDC to carry out a SARM (Safety, Availability, Reliability, Maintainability) analysis of the components to be used for the BHS installed in Inchon International Airport. This installation is a belt conveyor system. Our initial goal is the analysis of system components as 'stand-alone units' with the assistance of the relevant technical drawings, lists of the electrical parts for each unit, and the experience and estimates of engineers fully conversant with the MDC designs. This first step is to intended to designate those parts having major relevance for the reliability of each component, determine the respective SARM figures for these parts and thus calculate the relevant figures for each component. In a second step, the stand-alone units are combined to functional groups. These functional groups consist of one or more conveyors in combination for one specific task, i.e. if one conveyor of the functional group is defective, the whole group is out of service. As a further step, the SARM analysis has to be extended to the whole system. The mutual interactions between the functional groups and layout redundancies for baggage transport will be considered at this time. This will also include SARM for the control software of the BHS. Accurate statements with regard to maintainabilty can only be made after completion of the relevant technical documentation (maintenance and repair). It should be noted that the maintainability of equivalent conveyors differ considerably due to their installed locations. These effects on maintainability cannot be taken into account, as this would presuppose a detailed, on-site investigation of the whole plant. Such an investigation would last at least several weeks. The results of the analysis are also intended as reference data for the internal use of the MDC Engineering Departments in the design and implementation of future projects.

10 2 Safety 2.1 General The following section considers the various aspects of safety required to ensure the protection of persons and property (including facility equipment) against injury and damage during operation of the Baggage Handling System to be installed at Inchon International Airport. Aspects to be considered include the physical shielding and characteristics of equipment together with the provision of an adequate emergency-off system. The overall direction followed in the matters to be discussed is defined by the maxim of: Maximum Safety at Maximum Availability 2.2 Basic Standards The fundamental standards and guidelines requiring consideration are those currently valid in the European Community: EN 292; 'Safety of Machinery' EN 1050; 'Risk Assessment of Machines' EN 954; 'Safety-Related Parts of Control Systems' The EN 292 was compiled to assist designers, manufacturers and other interested parties in the interpretation of fundamental safety requirements. It defines a 'machine' as a combination of interconnected parts or devices, at least one of which is a moving part, with drive elements, control and power circuits for particular purposes of use. The EN 1050 sets general guidelines for the procedure of risk assessment and defines the information necessary for the performance of a risk assessment. The standard also defines the meaning of various terms, including 'risk' and 'risk assessment'. The EN 954 combines the 'machine risks' (based on the definitions in the EN 1050) with the equipment required to cope with and minimize these risks. It contains technical requirements and information for the configuration of safety-relevant parts of control systems, and defines categories with descriptions of the properties of the safety functions.

11 2.3 Definition of Risk General The basic terminology for the definition of risk is laid down in EN 1050: 'Boundary risk' 'Remaining risk' 'Probability of damage' 'Frequency and duration of exposure' 'Extent of damage 'Risk assessment' Fig. 2 1: Definitions Version: Section 2 Issued: Sept. 00 SARM-Analysis (of 28) page 3

12 2.3.2 Boundary Risk The boundary risk is defined as the 'maximal acceptable risk' of a technical process or condition Remaining Risk Any (acceptable) technical solution with regard to the safety of a machine or system will minimize the risk to a lower level than the boundary risk. However, there will always be a residual level of risk remaining risk whenever the relevant 'machine' is in use Probability of Damage The probability of possible damage will depend on several factors. One fundamental factor is, obviously, the type of 'machine' or technical system in question. The probability of damage occurring during use of, for example, a chain saw is considerably higher than that occurring during use of a pin-wheel printer. Additional factors are the type of use (e.g. direct hand-held usage of a drill or the remote control of a crane), the duration and/or frequency of use and also the area in which the machine or system is installed Frequency and Duration of Exposure According to the type of system, consideration has also to be given to frequency and duration of contact of persons interacting with the machine or system Extent of Damage The extent of possible damage also has to be taken into consideration : Type of protected interest: Persons Objects Environment Severity: Slight, reversible Severe, irreversible Deadly Range of damage: One person Several persons Risk Assessment The system described has to investigated for a combination of risk factors. For example: Severe injury possible with Frequent access of persons to the risk area Version: Section 2 Issued: Sept. 00 SARM-Analysis (of 28) page 4
