SDFD Fire Captain Practice Exam

Prior to landing a helicopter at night, wetting down the landing spot is a recommended practice. This action serves to reduce the potential for dust and debris to be kicked up during the landing process. In low visibility conditions, such as at night, minimizing dust is crucial as it can obscure the pilot's view and create unsafe landing conditions. Wetting the area ensures a clearer path and enhances safety for both the helicopter and any personnel involved.

In terms of context, while spotlighting vehicles might seem helpful, it can also create glare that hinders visibility. The use of emergency flares is generally more suited for signaling and may not be the best method for preparing a landing area. Setting up a security perimeter, while important for scene safety, does not directly address the specific concerns of landing in reduced visibility conditions. Thus, managing the environment by wetting the landing area is the most effective approach for a safe nighttime helicopter landing.
