Question: An excavator is trenching for a new sewer line adjacent to an existing, active natural gas pipeline. According to Alberta OHS Code Part 32, what is the minimum safe excavation distance from the identified natural gas pipeline if its exact location is confirmed?
Answer options: ✅ 0.3 metres (1 foot)
- 0.6 metres (2 feet)
- 1.0 metre (3.3 feet)
- 1.5 metres (5 feet)
Correct answer: 0.3 metres (1 foot)
