How to fully protect. TPS61032 and others

Other Parts Discussed in Thread: TPS61032, TPS40200

Hi everyone!

I'm using TPS61032 in my two stage power supply design (TPS40200 followed by TPS61032), it is in pre-production stage and I'm changing some resistor values and maybe doing short circuit sometimes, but the thing is that TPS61032 seems to be very fragile, brokes and shorts SW pins (1,2) with GND (11). 
I know this is my fault, but: ¿what are the best protections to avoid problems and broken?

Thanks
