Two years after the tragic Silkyara-Barkot tunnel collapse, which trapped 41 workers, India is poised to introduce more stringent safety norms for tunnel construction. The incident highlighted critical gaps in planning, execution, and emergency response for large infrastructure projects. The Ministry of Road Transport and Highways (MoRTH) is reviewing existing guidelines and is expected to mandate comprehensive geological surveys, advanced risk assessment, and robust escape routes for all future tunnels.
This move aims to prevent similar disasters, ensure worker safety, and enhance the resilience of India's rapidly expanding infrastructure network, particularly in challenging Himalayan terrains. The new norms are crucial for sustainable and safe development.

Practice Questions (MCQs)
1. Consider the following statements regarding infrastructure project safety in India: 1. The Ministry of Road Transport and Highways (MoRTH) is the nodal ministry for formulating safety norms for all types of infrastructure projects, including railways and airports. 2. The proposed new safety norms for tunnels are expected to mandate comprehensive geological surveys and robust escape routes. 3. The National Disaster Management Authority (NDMA) primarily focuses on post-disaster response and does not have a mandate for pre-disaster mitigation in infrastructure projects. Which of the statements given above is/are correct?
- A.1 only
- B.2 only
- C.1 and 3 only
- D.2 and 3 only
Show Answer
Answer: B
Statement 1 is incorrect. MoRTH is primarily responsible for road transport and highways. Different ministries (e.g., Ministry of Railways, Ministry of Civil Aviation) are nodal for their respective infrastructure sectors. Statement 2 is correct, as per the news summary, the new norms will mandate comprehensive geological surveys and robust escape routes. Statement 3 is incorrect. NDMA's mandate includes both pre-disaster mitigation (e.g., risk assessment, vulnerability reduction) and post-disaster response. It plays a crucial role in developing guidelines for disaster-resilient infrastructure.
2. In the context of large-scale infrastructure projects in the Himalayan region, which of the following statements is/are correct? 1. The Himalayan region is tectonically stable, making it ideal for large-scale tunneling without significant seismic risks. 2. Environmental Impact Assessments (EIAs) are mandatory for all major infrastructure projects in ecologically sensitive zones like the Himalayas. 3. The Main Central Thrust (MCT) is a significant geological feature in the Himalayas, representing a major fault line with implications for construction. Select the correct answer using the code given below:
- A.1 and 2 only
- B.2 and 3 only
- C.3 only
- D.1, 2 and 3
Show Answer
Answer: B
Statement 1 is incorrect. The Himalayan region is tectonically active, prone to earthquakes and landslides, making construction challenging and risky. Statement 2 is correct. EIAs are a crucial tool for assessing and mitigating environmental impacts of projects in sensitive areas. Statement 3 is correct. The Main Central Thrust (MCT) is one of the major geological fault lines in the Himalayas, indicating significant tectonic activity and posing challenges for civil engineering projects.
3. Which of the following provisions are generally considered crucial for ensuring worker safety and project resilience in large infrastructure projects, as highlighted by recent incidents? 1. Mandatory provision of multiple escape routes and safe chambers within long tunnels. 2. Real-time monitoring systems for geological stability and structural integrity. 3. Comprehensive insurance coverage for workers, irrespective of safety measures. 4. Regular mock drills and training for emergency response personnel and workers. Select the correct answer using the code given below:
- A.1, 2 and 3 only
- B.1, 2 and 4 only
- C.3 and 4 only
- D.1, 2, 3 and 4
Show Answer
Answer: B
Statements 1, 2, and 4 are crucial for worker safety and project resilience. Mandatory escape routes and safe chambers (1) provide immediate refuge. Real-time monitoring (2) allows for early detection of potential hazards. Regular drills and training (4) ensure effective emergency response. Statement 3, while important for worker welfare, is about financial protection post-incident rather than a direct measure for *ensuring* safety and resilience in project execution itself. Safety measures aim to prevent incidents, while insurance covers consequences.
