Introduction: Noise is a common pollutant in the workplace, particularly in the mining sector, which uses equipment that generates noisy environments. The aim of this study was to assess the occupational noise exposure of workers at a mining company in Senegal. Methodology: This was a retrospective, cross-sectional, and descriptive study that covered data recorded from May 2, 2016 to December 31, 2020. Results: A total of 393 noise exposure points were measured, with 17.6% exceeding 85 dB. The power plant was the noisiest area, with 53.8% of measurements exceeding 85 dB. Individual measurements of 51 workers in similar exposure groups (SEGs) from each department showed daily average exposure values ​​ (AELs) ranging from 55 dB in the SEG of WCP control room operators to 109 dB in the SEG of power plant electricians. Instantaneous noise exposure values ​​ (peaks) ranged from 115 dB in the WCP mechanics’ Similar Exposure Group to 143 dB in the MSP maintenance workers’ Similar Exposure Group. 85.6% of respondents had at least 5 years of service. Hypertension (4.9%) and moderate hearing loss (0.7%) were also recorded. Conclusion: Noise pollution is a reality at the Grande Côte Opération (GCO) mine. However, the technical and organizational measures implemented by the company have helped to reduce its harmful effects on workers’ health.

Introduction: Smoking constitutes a serious risk to the health of workers. The objective of this study was to evaluate the knowledge of caregivers on the harmful effects of tobacco and their perception of the actions to be promoted for a tobacco-free hospital. Methodology: This was a cross-sectional, descriptive study, carried out from April 1 to May 31, 2021 at the hospitals of Kossodo and Boulmiougou in Ouagadougou. Data collection was done using an anonymous, pre-established self-administered questionnaire. Results: A total of 246 caregivers were participated in the study. The average age was 44.8 years and 77.2% had more than 10 years of seniority in the function. The existence of the anti-tobacco law in Burkina Faso in public places was known by 78.9% of caregivers. Most caregivers were aware of tobacco-related harm (93.5%). The most known tobacco-related pathologies were lung cancer (55.3%), throat cancer (13.8%). Posters (88.2%), the ban on smoking in hospitals (93.9%), staff training (80.5%) and monitoring of compliance with the anti-smoking law (46%) were the major means recommended to achieve a tobacco-free hospital. Conclusion: Caregivers should serve as role models in tobacco control. The establishment of an anti-tobacco surveillance committee in health structures and the strengthening of awareness are to be promoted.

Objectives: It consisted in evaluating psychosocial risk factors among midwives/ maieuticians of Yalgado Ouédrago University Hospital Center of Ouagadougou. Methodology: This was a descriptive, cross-sectional and analytical study, carried out using an anonymous self-questionnaire. The Karasek scale was used to identify risk situations. Data were entered and analyzed using Epi info version 7.0 software. The significance level chosen was p < 5% to assess the link between socio-professional variables and stress. Result: A total of 42 midwives/maieuticians were participated in the study. The average age was 38 years old. Women predominated (71.4%). The average weekly working hours was 45 hours. The average number of monthly guards was 6. The average seniority in the profession was 10.5 years. The prevalence of psychosocial risks was 88.1% for psychological demand, 57.1% for low decision latitude and 64.3% for low social support. Value conflicts (71.4%), job and work insecurity (52.4%) and emotional demands (21.4%) were collected. The prevalence of job train was 52.4% and that of isostrain was 26.2%. The correlation between socio-professional variables and stress was not statistically significant (p˃0.05). Conclusion: Psychosocial risks are omnipresent among midwives/maieuticians. It is urgent to promote the creation of occupational health services in care settings in order to improve the psychosocial environment and to detect the suffering of caregivers early.

Objectives: To identify occupational risks factors in the artisanal dyeing factories of Bamako and to propose appropriate preventive measures. Equipment and methods: This is a prospective and descriptive study conducted over a period of 6 months, from April to September 2014, among dyers in Bamako. The study instrument was a 24-item questionnaire on socio-professional characteristics and data analysis was performed by the Epi Info software, version 6.4. Results: Our study population was 100 dyers with a sex ratio of 5.67 in favour of women (17 women for 3 men). The average age was 31.9 years with extremes of 15 and 70 years. Married people were in the majority with 70% and 38% of the dyers had between 1 and 3 children. The dyers were enrolled in school in 44% of cases, 30% of which were in Arabic. Soakers were more numerous with 43%, followed by rinsers 28% and blenders 15%. The majority had no professional qualification, i.e. 94%, and 48% had more than 5 years of experience in the profession.
