You need to modify the attributes of both Title and Bullet Points styles so they both have "Keep Together" and "Keep with next" turned on.

THEN
You need to insert a small empty paragraph immediately before every Hazard heading that DOESN'T have 'Keep with Next' turned on. An alternative is to use a duplicate Bullet Points style called "Bullet Points Last" which doesn't have Keep with Next on which you must use on the final paragraph before the Hazard heading.
