Risks in the process of oil production

Workers employed at drilling sets and other jobs in oil production are exposed to various conditions. They work outdoors and they are exposed to all atmospheric influences throughout the year. Their work is often connected to hard phisical strains/exertions, especially while/during the assembly of drilling sets or repairwork.
