Abstract

Objectives To study exposure to noise, the attitudes and knowledge towards noise-induced hearing loss and the actual use of hearing protection in a steel rolling mill in Nigeria. Methods A structured questionnaire was administered to 116 randomly selected workers to collect information relating to their knowledge and attitudes towards hazardous occupational noise and preventative measures. Noise mapping of the factory was also carried out. Results Time weighted average noise levels were: administrative area 49 dBA, mechanic/maintenance workshop 72 dBA, mill floor 86 dBA and finishing stage 93 dBA. There was high awareness of the hazard of noise to hearing (93%) and of methods of prevention (92%) but only 27% possessed hearing protectors and only 28% of these stated that they used them all the time. Conclusion While noise is recognized as a hazard, initiatives are required to increase use of effective preventative measures.
