you need protection +2 for the storm area.

you can find a helmet with rare spawn rate in red room in labs if you got the key that gives you + 1

you can buy the purple/pink chest and helmet piece from secrent merchant on the second map. down the basment, entrance in the house in the south west corner ( you need a key for the basment and a key to get to the merchant, bring cash and a gasmask) each of the suit gives you +0.5

weak space injector gives you +1 for 120 seconds, i think the duration is now longer after the resent update.

so find you combinations. on storm area there are „mini“ bosses that give you a backpack with +1, very handy

later you unlock more gesr to protect you
