A Study of performance measurement of safety systems in construction.

Naik, Nitin, CIVIL AND ENVIRONMENTAL, UNSW January 2006 (has links)
In Australia, the measurement of safety performance in the construction industry has mostly been in response to statutory requirements. Consequently, the measures and Key Performance Indicators (KPIs) used by the industry have invariably focused on outcomes rather than processes. Most of the outcome indicators have tended to give their feedback well after the event therefore failing to identify any weaknesses within the safety management processes. In order to overcome these limitations, two hospital construction projects in New South Wales were selected for an in-depth study and research analysis. The aim of the research was to understand the relationship between management process intervention and management process outcomes for safety in the construction industry. Initially a literature review identifying international practices in performance measurement for safety in construction was conducted so as to review existing safety management processes in partnership with the construction industry representatives. A framework for measuring the performance of safety management processes and related outcomes was developed to stimulate improvement on both projects through the comparison of the performance of the safety management systems and outcomes. This framework was then implemented and established to monitor the performance of the key safety management processes. The successful implementation of the performance measurement framework and the feedback to both stakeholders and subcontractors acted as a good communication tool in creating awareness among subcontractors. It also helped to reduce repetitive hazards, resulting in improved safety outcomes. A statistical analysis found that relatively few injuries were explained by the identified safety hazards. This highlighted the need to look for hazards that were specifically relate to injury occurrence. The research findings identified a method for improving the existing hazard identification process. It is anticipated that such improvements can help to better correlate hazard management processes with the project outcomes for safety in future projects.

Fire Safety System Effectiveness for a Risk-Informed Design Tool

Frank, Kevin Michael January 2013 (has links)
The purpose of this research is to identify how uncertainty in fire safety system effectiveness should be considered in a new risk-informed design fire tool, B-RISK. Specific objectives were to collect the available data on fire safety system effectiveness from the literature, investigate methods to improve fire safety system effectiveness data collection, develop the risk-informed design fire tool to propagate the uncertainties, and recommend methods to rank the sources of uncertainty for fire safety system effectiveness for appropriate model selection. The scope of the research is limited to the effects of systems on fire development and smoke spread and does not include the effects of the fire on systems (such as loss of structural integrity) or interactions with occupants. Sprinkler effectiveness data from recent New Zealand Fire Service data is included with a discussion of the uncertainty in this type of data and recommendations for improving data collection. The ability of the model to predict multiple sprinkler activations is developed in conjunction with a hydraulic submodel in B-RISK to include water supply pressure effects on sprinkler effectiveness. A new method of collecting reliability data on passive fire protection elements such as doors was developed. Data collected on the probability for doors in shared means of escape to be open and the time doors are open during occupant evacuation using this method is presented. Available data on smoke management system effectiveness is listed, along with a discussion of why there is more uncertainty associated with these systems compared with sprinkler systems. The capabilities of B-RISK for considering fire safety system effectiveness are demonstrated using Australasian case studies.

NETWORKED DATA ACQUISITION DEVICES AS APPLIED TO AUTOMOTIVE TESTING

Mastrippolito, Luigi 10 1900 (has links)
International Telemetering Conference Proceedings / October 20-23, 2003 / Riviera Hotel and Convention Center, Las Vegas, Nevada / The US Army Aberdeen Test Center (ATC) is acquiring, transferring, and databasing data during all phases of automotive testing using networked data acquisition devices. The devices are small ruggedized computer-based systems programmed with specific data acquisition tasks and then networked together with other devices in order to share information within a test item or vehicle. One of the devices is also networked to a ground-station for monitor, control and data transfer of any of the devices on the net. Application of these devices has varied from single vehicle tests in a single geographical location up to a 100-vehicle nationwide test. Each device has a primary task such as acquiring data from vehicular data busses (MIL-STD-1553, SAE J1708 bus, SAE J1939 bus, RS-422 serial bus, etc.), GPS (time and position), analog sensors and video with audio. Each device has programmable options, maintained in a configuration file, that define the specific recording methods, real-time algorithms to be performed, data rates, and triggering parameters. The programmability of the system and bi-directional communications allow the configuration file to be modified remotely after the system is fielded. The primary data storage media of each device is onboard solid-state flash disk; therefore, a continuous communication link is not critical to data gathering. Data are gathered, quality checked and loaded into a database for analysis. The configuration file, as an integral part of the database, ensures configuration identity and management. A web based graphical user interface provides preprogrammed query options for viewing, summarizing, graphing, and consolidating data. The database can also be queried for more detailed analyses. The architecture for this network approach to field data acquisition was under the Aberdeen Test Center program Versatile Information System Integrated On-Line (VISION). This paper will describe how the merging of data acquisition systems to network communications and information management tools provides a powerful resource for system engineers, analysts, evaluators and acquisition personnel.

An assessment of the effectiveness of behaviour-based safety systems in establishing organisational culture / J. Cronje

Cronje, Jennifer January 2010 (has links)
People, processes and teams form the basis of organisational success. Therefore the understanding and prediction of people and their behaviour- both individual and in a team - is a critical management activity. Behaviour of people are influenced by internal factors such as personality, abilities and skills, perception, beliefs and motives as well as by external factors from the environment in which the individual operates. Understanding these forces and their influence on the individual is paramount if one is to understand how to canalise these behaviours to achieve any given organisational goal. Another concept important to understand, is that of organisational culture which is regarded as beliefs, values and learned ways of coping with experience. Organisational culture develops during the course of an organisation's history, and has become a more and more important concept in organisations, due to its strategic nature and impact on business. The culture of an organisation can be influenced and changed naturally over time, or by using deliberate, carefully designed cultural change interventions. The maturity of an organisation's HSEC systems and processes and related improvement in performance, is related to the prevailing HSEC culture evident in the organisation. It is evident that as an organisation moves from a reactive safety culture to an interdependent safety culture, so does the HSEC performance and lagging indicators of the organisation increase. Behaviour-based safety processes endeavour to influence the individual employee's behaviour in order to improve the safety performance of an organisation. The benefits of behaviour-based safety programs are numerous and lead to reduced injuries and improved levels of safe behaviour amongst employees. Metalloys has selected behaviour-based safety as one of the tools to entrench a culture of zero harm in the organisation and to establish an empowered and enabled workforce. The effectiveness of this approach was assessed during this study The empirical research conducted for this study revealed that both the average response rate per construct and the responses per question within the various constructs reflect a positive response to the elements tested. It is evident from the results that a large proportion of the employees are of the opinion that communication processes are effectively established, employees are involved on a personal level, that there is sufficient supervisor support and that leadership exhibits visible leadership in the organisation. These are all constructs testing the elements required to effectively establish the culture of the organisation. In addition, a large proportion of the employees felt that HSEC systems are well entrenched and that facilities and equipment are of such a standard, as to ensure the safety of employees and that these are maintained at high levels. / Thesis (M.B.A.)--North-West University, Vaal Triangle Campus, 2010
