Título Lighting conditions for mould and coremaking operations in foundries

Resumen Subjective observations and measurements of lighting were obtained for 5 foundries; detailed studies were made and several arrangements were tested in 2 of them. Visual tasks were difficult because the dark moulding sand allows no contrast; shadowing in mould and core cavities further decreases the light. Workplace lighting is rare even though general lighting is ineffective. Workers frequently have to adopt postures which cause them to shade the working area with their bodies. In some places, illumination levels were sufficient, but quality was unacceptable due to wrong direction and glare. Spot check interviews of 15 core makers produced complaints about the direction of the light for manual work; 13 indicated workplace lighting would be an improvement. Suggestions are made for such lighting.
