in-place protection

If you're in an NBC environment, decontaminate the area around the leak immediately, and seal it. If you're not in an NBC environment, turn the mask in to your unit NBC NCO, and have it deadlined for repair. So long as that leak exists, the equipment is to be considered inoperable.

not a good idea, most products you can find in the household are not leak proof and do not make a complete seal. sperm will still get through, a cervical barrier should be professionally fitted by a doctor so that it is a tight seal and should be made of a material with no holes in it like a latex type material.
This depends what shut off valve is in question here. Where the leak is and what type of material is the shut off valve made of.
