The Range Safety Diagram

We have found three tools to be especially helpful when faced with a paper tiger in need of information. The first two - the Model Rocket Safety Code and the Typical Flight Diagram - we have discussed in previous chapters. The third and possibly most effective communication tool is called the Range Safety Diagram (RSD).

Think about it. How many times have you looked up one of those popular map sites on the internet before you headed off to a new movie theater or restaraunt? The same applies to model rocketry. For administrators, parents, students, and staff who have never been to a launch site, the RSD provides a much needed roadmap to help navigate a new and exciting experience.

As a graphic map of your proposed launch area with important locations indicated, the RSD fulfills four important functions. First, the RSD is a safety tool showing the locations of rockets, students and spectators and ensuring that proper distances have been accounted for. Second, the RSD is an educational tool that can be reviewed with your club before each launch - thus insuring that everyone knows just where (and where not) to be on the field. Third, the RSD a spectator management tool that can be publicly posted to ensure your audience understands the layout of your range. Last, the RSD is a program-specific tool allowing the information from both the Safety Code and the Typical Flight Diagram to be summarized and applied to the actual area you are intending to use for your launch.

A good RSD does not have to be computer generated or highly detailed to be effective. A clear diagram that includes the following basic information is ideal: a general layout of the space you will be using as the launch area. Be sure to include any buildings, trees or other obstructions; the location and distance between the launch pad, participants and any possible spectators; and the expected direction of the model rockets flight path (it also helps to include the typical wind direction for the area).

A well planned RSD helps a doubtful administrator or hesitant parent visualize your launch field for themselves and demonstrates that you have already have a competent safety plan in place.
