With a fuel pressure regulator set at 3.5psi, properly set float, quality needle and seat, there should be no particular fire hazard compared to other carbs.
When it is said that tri-powers pose a special fire hazard, what they are really saying is that they are more prone to fuel leaks. There is some logic in that there are more fuel fittings, so more potential leak points, but I am not overly concerned.
