Did I Do Right?

[dddunn3d]

FED rules, R3(I'm in 'C'). B1 squares to bunt, R3 starts towards home. B1 misses the bunt and F2 fires down to F5. R3, F5 and the ball all get to the same point in space at the same time. The problem is

• it's a dry, dusty field
• the wind is blowing about 10KTS directly from the west, and
• the setting sun is directly behind 3B in my line-of-sight.

These factors combine to totally and completely obscure my view of the play. I set, look, and... see nothing but dust and glare. I come up, point to my partner who has come up the line a few steps, and say "I was completely obstructed, what do you have?" He said "Runner was safe." So I signal safe.

Is this an appropriate technique(and mechanic) to use in this type of situation? I ask because I've always heard to get your own calls.
