We stopped giving our products safety distances back in 2000. There were lots of reasons for us doing this. The main reason was that many operators are using pyro at angles and sometimes even upside down. If we were to give a safety distance and someone got hurt, we could be liable. Instead of issuing safety distances, we now recommend that you fire the effect in controlled conditions outside to familiarise yourself with the effect. You can then implement any safety distances yourself and document them in your risk assessment.
