For people to carry out their work activities, there is a code of protection in the workplace. This is especially important in activities where the worker's physical integrity is at risk, such as working in mines, works, plantations or activities in unhealthy environments.
When there is an overhaul of the safety laws, it means that some flaw in the previous law has been perceived, so the new legislation is aimed at solving the risk positioning and giving a better protection to the worker.
