Soldering Station for screen repair

I was wondering about how safe is it to use a smd remork station that has a hot air gun to heat the back cover of phones for lcd replacements repairs?

I have the baku 702b, the minimum temperature is 150c. The air feels hot, and my hand can bear for about 7 seconds at a 10 cm distance.

How about glass only repairs with this gun, would it be too dangerous to use it?
