Which way should the front of the CBRN sign face relative to the contaminated area?

• A. Facing toward the contaminated area
• B. Facing east
• C. Facing randomly
• D. Facing away from the contaminated area

Answer: (D)

In this context, the most important idea is that hazard signs should be oriented so the readable side is toward the area you want people to approach from—the safe side. Facing away from the contaminated area makes the front of the sign visible to personnel on the clean side as they approach the boundary, giving them clear warning before entering. If the sign’s front faced the contaminated area, the warning would be directed toward the danger itself, not toward those who need to see it in time. Directional or random orientations don’t carry safety significance; the key is that the readable face points away from the hazard so it's seen by people approaching from the safe area.
