145. Article 214 adds that in order to meet the requirements of this obligation, the employer should demand the essential skills for each specific case. Where this knowledge does not exist in the firm, external specialists like labour inspectors specializing in workplace safety and health, ergonomists, labour psychologists or any other person with the relevant competence should be called upon. 146. According to Article 372 of the regulatory section of the labour code, a workplace safety and health committee (CSST) should be set up in all firms or all establishments subject to the Labour Code and employing at least fifty (50) salaried workers. The number to be taken into consideration is the number of workers usually engaged in the establishment, whether their names are necessarily entered into the register of the employer or otherwise. 147. Note is also taken of the launch of the “Zero Vision” campaign in all the regions of the country in 2019 which is based on the prevention of occupational risks; it is a transformational prevention approach developed by the International Social Security Association (ISSA) which includes the three (3) dimensions of the health, safety and wellbeing at the workplace and is based on seven (7) golden rules: 1. Show leadership – demonstrate one’s commitment; 2. Identify dangers – assess risks; 3. Define objectives – formulate programmes; 4. Ensure a safe and healthy system – be organized; 5. Ensure safety and health on machines, equipment and work premises; 6. Improve qualifications - develop skills, and 7. Invest in the person - motivated by participation. 148. This campaign is a strategy for the prevention of work-related accidents based on the conviction that all accidents, sicknesses and their multiple consequences are avoidable and that it is possible to have a world without serious and fatal accidents. Note is also taken of the institution of the African Day for the Prevention of Occupational Risks (JAP). Every year, as part of efforts towards the prevention of occupational risks, the month of April has been declared as the “occupational risk prevention month” by the African Institute for the Prevention of Occupational Risks (IAPRP). Finally, there is the African Occupational Risk Prevention Fair (SAPRIP) which takes place every three (3) years as part of efforts towards the prevention of occupational risks. 149. On the right to equal pay for equal work, the information contained in the last report is still relevant. 150. With regard to the right to rest, leisure and a reasonable limit of working hours, Article 138 of the regulatory section of the labour code states that, in certain professions, as a result of the intermittent nature of work, duration of presence higher than the legal duration of work is considered as equivalent to forty hours of actual work. 151. The equivalent weekly working hours are as follows: - 42 hours for hospital staff assigned to sales in pharmacies and retail trade; - 45 hours for staff of hospitals and all health care, convalescence and rest establishments, staff assigned to retail sales in cake shops and bakeries as well as cooks in hotels and restaurants; - 48 hours for drivers exclusively assigned to the transportation of staff of a firm and coach and private vehicle drivers as well as male and female nurses; 39
