Safety First: Essential PPE and Protocols in Microtunnelling Operations
In the world of underground construction, precision is vital, but safety is mandatory. Operating a TBM or Microtunnelling machine like the MARS 450 requires more than just technical skill; it requires a deep commitment to protecting every life inside the shaft. Based on my 7+ years of experience, I believe that a clean safety record is the mark of a true professional
1. Fall Protection: The Full Body Harness
Working in deep jacking shafts presents a constant risk of falls.
Mandatory Use: Every worker entering the shaft must wear a certified Full Body Harness.
Safety Anchor: These harnesses are essential for fall arrest and provide a secure way to rescue personnel in case of an emergency.
2. Personal Protective Equipment (PPE) Standards
Head Protection: Safety helmets are worn at all times to protect against falling objects from the surface.
High-Visibility Gear: Reflective vests ensure that workers are visible to the operator and crane drivers, even in the low-light conditions of the shaft.
3. Confined Space Ventilation
Proper air circulation is a lifesaver in tunnelling.
Air Supply: As seen in my site photos, we use large orange ventilation ducts to pump fresh air into the tunnel.
Gas Monitoring: This system prevents the buildup of dangerous gases, ensuring a breathable atmosphere for the crew.
Conclusion
Following international safety standards, such as those used in Europe or New Zealand, is not just about rules; it’s about responsibility. When my team wears their PPE correctly, it shows their discipline and our project's professionalism
