In view of the current health crisis, the operation consists of the acquisition of equipment and supplies for public service workers at risk of exposure, continuing their activities and in direct contact with the population in general. As these agents were exposed to the risk of COVID 19 contamination, it was necessary to equip them, inter alia, with masks, hydro-alcoholic gels, safety visors, gloves to ensure their safety. In addition, it was also necessary to ensure that officers were able to work safely in the field or in their offices. As early as mid-March — so at the very beginning of the health crisis — the Pole C control officers and the inspectors and controllers of the work centre had to intervene in large areas, businesses and local shops to carry out their tasks and to ensure that all measures, including barriers, were respected and to bring their expertise to local decision-makers, including during the containment phase. On the specific question of the price survey by pole C, whose competitive actions of the markets and the economic protection of consumers are among the priority tasks of the business continuity plan: The services of Pole C (24 agents) in a social context marked by the demonstrations of yellow vests that marked Reunion hard and at the request of the Prefect and the Ministry of Finance, from the origin of the crisis ensured a price survey in large and medium-sized areas, retail stores, pharmacies, as well as on the fair markets. This approach has made it possible to object to price increases and limit their developments to the height of the health crisis. Surveys conducted to observe price trends for first-needed products and, in particular, that of fruit and vegetables have led, for example, to major declines through reminders to the order of retailers with very high retail prices, notably up the supply chain (-calculation of gross margin _in situ_). The same was true of the pharmaceutical prices of hydro-alcohol products or the sale or quality of masks in order to ensure price reductions so that users could buy these products at the right price and thus use them to limit the spread of the virus. Given the crisis situation, purchases were made without publicity or competitive tendering, as specified in the derogating procedure laid down in Article R2122-1 of the Public Procurement Code.
