The influence of training and education on the perception of laser safety

Abstract

Previous research into training and education in laser safety has highlighted the limited scope of topics taught on the majority of training programmes. Research has shown that laser safety training concentrated more on radiation and legal issues than the associated hazards or practical control measures available. Evidence is also available to show the majority of safety procedures used by the UK laser community rely upon administrative controls, (eg. signs and labels) and personal protective equipment over and above engineering controls.Loughborough University and the National Radiological Protection Board (NRPB) have worked together over the past 3 years to establish a new series of laser safety training courses that provide a more balanced syllabus of topics. Particular emphasis has been given to teaching practical methods for laser hazard reduction and control.Research has been conducted into the preconceptions of those attending our training courses. Analysis was undertaken of issues delegates considered essential for laser safety and the importance they gave to particular topics. One aim of the research was to identify whether it was possible to change the rating of importance as a result of laser safety training.Results from the research have been very encouraging. For example, it has been possible to change the opinion that protective eyewear is essential to laser safety (pre-course opinion) to a lower rating of important (post course opinion). At the same time, the importance of engineering control measures was significantly raised.This paper describes the pre-and post course analysis and presents results from research into the opinions of those who have attended our courses. An outline of the different courses is also presented.Previous research into training and education in laser safety has highlighted the limited scope of topics taught on the majority of training programmes.
