JFRD Standard Operating Guideline (SOG) Practice Test

When placing a ladder near potential utility lines, you must account for multiple kinds of hazards, not just one. There are three common types of utility lines you should be mindful of in most settings: electrical power lines, gas lines, and water or other service lines. Treat all of these as possible hazards and keep the ladder well clear of any of them. That means the minimum number of utility lines to consider is three—you can’t safely rely on avoiding just one or two of them. If you encounter more lines or can’t clearly identify all services in the area, you should pause, verify with utility locating, and adjust setup to maintain safe clearances. The other options don’t fit because they imply you only need to consider fewer lines (which risks missing another active hazard) or more lines (which isn’t the baseline standard for the minimum).
