The process of constructing concrete sewage tunnels involves various work-related risks
that demand careful planning and the implementation of effective safety measures. This
includes work both in the production halls at the company headquarters and on-site during
the installation of formwork for tunnel construction. In my thesis, we focused on the risks
associated with welding and sandblasting, where workers are exposed to a range of
hazards. The company ensures safety through a combination of technical and
organizational measures, with personal protective equipment (PPE) playing a central role.
This includes protection for the head, hearing, eyes, respiratory system, hands, body, feet,
as well as fall protection systems. Proper use of PPE is essential, serving as the final line
of defense against injuries and occupational diseases. The findings indicate that workers
conscientiously use PPE, not only because of supervision but also due to a strong
awareness of its importance in maintaining workplace safety. In addition to providing the
necessary safety equipment, the company regularly conducts professional training in
collaboration with an external provider specialized in occupational safety, fire safety, and
the handling of hazardous chemicals. For the risk analysis, we based our approach on the
risk assessments for welders and sandblasters, which enable the systematic identification
of hazards, the evaluation of their severity, and the determination of appropriate safety
measures to mitigate risks and ensure a safe working environment.
