**Step-by-Step Solution:**

1. **Understanding Natural Gas**: Natural gas is primarily composed of methane, which is a colorless and odorless gas. This means that in its pure form, it does not have any smell.

2. **Adding Odorants**: To make natural gas safe for use, an odorant is added. The most commonly used odorant is a substance called mercaptan, which has a strong smell similar to that of rotten eggs.

3. **Purpose of the Odor**: The strong smell of the added odorant is crucial for safety. It allows individuals to detect the presence of natural gas in the environment.

4. **Detecting Gas Leaks**: When there is a gas leak, the rotten egg smell becomes noticeable. This helps people to identify the leak quickly and take necessary precautions to avoid accidents, such as explosions or fires.

5. **Conclusion**: Therefore, the natural gas odour is helpful in detecting gas leakages.

**Final Answer**: Natural gas odour is helpful in detecting gas leakages.
