Knowledge, Attitudes, and Practices on Occupation Health and Safety Amongst Mine Workers Exposed to Crystalline Silica Dust in a Low-Income Country: A Case Study from Lesotho

Abstract

Exposure to respirable crystalline silica dust is one of the most common and severe risks due to the associated health outcomes among workers and results in many occupational-related lung diseases, such as silicosis and lung cancer. The study aimed to determine knowledge, attitudes, and practices on occupation health and safety among mine workers exposed to crystalline silica dust in Lesotho. A descriptive retrospective cross-sectional study design was used in the study. A record review guide was used to retrieve secondary data from the Southern Africa Tuberculosis and Health Systems Support (SATBHSS) project, which were thereafter entered into STATA software, version 17 for descriptive and inferential analysis. The study participants were purposively selected. Most participants were between the ages of 31 to 40 years of age and there was a significant difference between the genders with 35 (9%) females and 350 (91%) males. The majority of the participants had a high school level of education (305, 79%). The knowledge was generally positive in the study with a knowledge score mean of 13.43 (standard deviation: 2.99). The miners agreed with most attitude statements except for A1 (25%), A2 (35%), A3 (18%), and A4 (31%). The practice of exposed mine workers in the study was influenced by working in a dolerite mine (p = 0.003), knowledge score (p ˂ 0.001), and having an attitude about health and safety rules at the mine (p ˂ 0.001; 95% CI: 0.92 to 0.79), while age was a protective factor in the study. The findings of this study highlighted positive knowledge, attitudes, and practices toward occupational health and safety among mine workers. However, more educational programs can be implemented to ensure all mine workers understand the importance of good knowledge, positive attitude, and appropriate practices towards occupational health and safety in their environment.
