Robotic testing of radio frequency devices designed for industrial safety

An experimental setup is proposed to test the performance of safety devices based on radio frequency technology. The setup specifically tests devices designed for improving safety in dangerous areas of small size, such as those surrounding power press brakes. Tested here is a radio frequency identification (RFID) prototype, whose main objective is to prevent accidents by sending a stop signal to a machine when a worker's wrist, bearing an RFID tag, gets too close to the dangerous area.

A visual warning system to reduce struck-by or pinning accidents involving mobile mining equipment

This paper describes an experiment to examine whether a visual warning system can improve detection of moving machine hazards that could result in struck-by or pinning accidents. Thirty-six participants, twelve each in one of three age groups, participated in the study. A visual warning system capable of providing four different modes of warning was installed on a continuous mining machine that is used to mine coal. The speed of detecting various machine movements was recorded with and without the visual warning system. The average speed of detection for forward and reverse machine movements was reduced by 75% when using the flashing mode of the visual warning system. This translated to 0.485 m of machine travel for the fast speed condition of 19.8 m/min, which is significant in the context of the confined spaces of a mine. There were no statistically significant differences among age groups in the ability to detect machine movements for the visual warning modes in this study. The visual warning system shows promise as a safety intervention for reducing struck-by or pinning accidents involving continuous mining machines. The methods and results of this study could be applied to other moving machinery used in mining or other industries where moving machinery poses struck-by or pinning hazards.

Z462-12 - Workplace electrical safety

This edition will both technically update the Standard and adds a considerable amount of resource material : especially for organizations seeking to make electrical safety an integral part of their safety management system. Following are a few of the key changes to this high-value, nationally-recognized safety standard.

The internet of things (IOT) and cloud computing (CC) based tailings dam monitoring and pre-alarm system in mines

Tailings disposal is a significant consideration for the mining industry, with the majority of the ore processed in most mining operations ending up as tailings. Several tailings dam failure accidents have occurred during the past few years and mine tailings dam failures, which are disastrous with the serious damage and the loss of lives, are occurring at relatively high rates. To improve the tailings dam safety, a tailings dam monitoring and pre-alarm system (TDMPAS) based on the internet of things (IOT) and cloud computing (CC) is accomplished with the abilities of real-time monitoring of the saturated line, impounded water level and the dam deformation. TDMPAS has helped the mine engineers monitor the dam safety 24/7 and acquire pre-alarm information automatically and remotely in any kind of weather conditions. TDMPAS has been applied in several mines and has demonstrated the feasibility of monitoring the tailings dam physical condition.

Safety performance indicators in the explosives sector

Development of a worked example
The Health and Safety Laboratory (HSL) were originally approached by the Health and Safety Executive (HSE) to assist with the implementation of Safety Performance Indicators (SPIs) within the Explosives industry.
This work builds on the examples and indicators identified in previous work (Ferguson and Nash, 2008), and aimed to encapsulate the types of activities common to a large number of organisations. Previous work to generate Safety Performance Indicators (SPIs) had resulted in little consistency or commonality across the industry group in terms of the leading and lagging indicators developed. It was therefore considered that to engage the sector, a 'case study' or worked example should be developed.
