Background and aims: Permit to work (P.T.W) is a formal written system to control certain types of work which are identified as potentially hazardous. Although P.T.W is a means of safety system and coordinating different work activities to avoid conflicts, it may be susceptible for human error. The purpose of this study was quantitative human error assessment using engineering approach in P.T.W...
The subject of metabolites in safety testing has had much debate in the recent past and has shown itself to be a complex issue with no simple solutions to providing absolute assurance of drug safety. Much of the attention has focused on the ability to identify metabolites and then demonstrate that their risk has been adequately characterized, either through their exposure in toxicology species ...
Occupational safety is a complex phenomenon. If occupational safety management is to be successful, both the systematic and the systemic aspects of safety need to be understood. System dynamics modelling appears to be an appropriate methodology for exploring the array of occupational safety strategies open to employers. This paper summarises the process of developing, then empirically testing a...
BACKGROUND Implantable cardioverter-defibrillators and cardiac resynchronization therapy defibrillators have relied on multiple ventricular fibrillation (VF) induction/defibrillation tests at implantation to ensure that the device can reliably sense, detect, and convert VF. The ASSURE Study (Arrhythmia Single Shock Defibrillation Threshold Testing Versus Upper Limit of Vulnerability: Risk Reduc...
Management of microbiological food safety is largely based on good design of processes, products and procedures. Finished product testing may be considered as a control measure at the end of the production process. However, testing gives only very limited information on the safety status of a food. If a hazardous organism is found it means something, but absence in a limited number of samples i...
The usability and safety of health information systems have become major issues in the design and implementation of useful healthcare IT. In this paper we describe a multi-phased multi-method approach to integrating usability engineering methods into system testing to ensure both usability and safety of healthcare IT upon widespread deployment. The approach involves usability testing followed b...
Although the safety-critical system has high demand on safety, the cost of software test therefore must be taken account of. In the test of railway computer interlocking software carried out, the safety test for a station software last several months, therefore, in order to reduce the test time, it is practical to choose functions from the function set to test through optimization. Software saf...
BACKGROUND Food additives are an integral part of the modern food system, but opinion polls showing most Europeans have worries about them imply an urgent need for ethical analysis of their use. SOURCES OF DATA The existing literature on food ethics, safety assessment and animal testing. AREAS OF AGREEMENT Food additives provide certain advantages in terms of many people's lifestyles. ARE...
With the recent development of embedded system technology, automation of train control system software is being promoted. Software for safety-critical systems like the train control system software has to deal with the hazards identified by safety analysis in order to make the system safe, risk-free and fail-safe. However, systematic efforts to verify the safety of software have been rarely per...
