If the scaled distance is less than 50 when near a pipeline and the standard distance table is exceeded, what must the blaster do regarding structures in the area?

If the scaled distance is less than 50 when near a pipeline and the standard distance table is exceeded, what must the blaster do regarding structures in the area?

• A. Evacuate the area
• B. Provide notice to all structures in that area
• C. Post warning signs only
• D. Request police assistance

Answer: (B)

Scaled distance relates how far you are from the blast to how large the charge is, and it helps predict potential effects on nearby structures. When you’re near a pipeline and the scaled distance is less than 50 while the standard distance table would require a larger buffer, the required action is to provide notice to all structures in that area. This ensures everyone with a building or structure nearby is informed that blasting will occur and can take appropriate precautions. Evacuation isn’t automatically mandated by this condition, and simply posting warning signs or seeking police help doesn’t fulfill the notice requirement.
