Interval spacing between CBRN signs should be which of the following, depending on terrain?

• A. 1-10 meters
• B. 50-75 meters
• C. 200-300 meters
• D. 10-100 meters depending on terrain

Answer: (D)

Sign spacing for CBRN signs must be adaptable to terrain to maintain continuous warning and situational awareness. In areas with dense vegetation, rubble, or many obstacles, signs should be placed closer together—toward the lower end of the range—so the hazard is clearly indicated before you reach it. In open terrain with clear line of sight, signs can be spaced farther apart—toward the higher end of the range—without losing visibility or warning this is the aim. This flexible approach prevents missing warnings in challenging terrain while avoiding unnecessary clutter in open areas, so the appropriate interval falls roughly between 10 and 100 meters depending on the terrain.
