Is Lidar Lite V1 safe to use?

I have a Lidar Lite V1, which I was able to get working correctly in PWM mode. However, the documentation talks about an unresolved 13m offset that may spontaneously appear. As far as I can tell, this would likely cause an immediate crash if flying below 13m?

My question is, can this unit be used safely? I considered setting the maximum range-finder height to 10m for example.
