In tunnel construction, conditions are often hazardous due to limited airflow, potential toxic gas buildup, and accumulation of dust and debris. Workers may face exposure to harmful gases such as carbon monoxide, methane, and nitrogen dioxide, which can be released from machinery or geological formations. Without proper ventilation, these gases can reach dangerous concentrations, posing severe health risks to workers and leading to potential fire or explosion hazards. Furthermore, the presence of dust particles can impact respiratory health, contributing to long-term occupational illnesses.
