      (2)   Restrict or prohibit movement within, above or beneath the areas which, in his judgment, are imperiled by the public danger or emergency;
      (3)   Establish a curfew during such hours of the day or night as he deems advisable and prohibit persons from being out of doors during such curfew;
      (4)   Prohibit or restrict the retail sale, distribution or giving away of gasoline, or other liquid, flammable or combustible products;
