On occasion I have clipped the first bolt with a screwgate (done up) to minimise the potential fall distance so close to the ground.
Try and plan ahead, take enough draws, but Should you run out, use a screwgate and do it up.
Worth noting that if the lower off requires a re-thread you will want to prioritise the use of a screwgate here. You may only carry a couple on a route!
