How to make a fire extinguisher spray paint?
As long as this person is not blocking your driveway then there is really nothing that you can do North Carolina General Statutes § 20-162 Parking in front of private driveway, fire hydrant, fire station, intersection of curb lines or fire lane No person shall park a vehicle or permit it to stand, whether attended or unattended, upon a highway in front of a private driveway or within 15 feet in either direction of a fire hydrant or the entrance to a fire station, nor within 25 feet from the intersection of curb lines or if none, then within 15 feet of the intersection of property lines at an intersection of highways; provided, that local authorities may by ordinance decrease the distance within which a vehicle may park in either direction of a fire hydrant..
Do you mean a smoke alarm or a sprinkler that sprays water from the ceiling? If its thick enough it MAY set off a smoke alarm. However it will NOT set off a sprinkler, they activate when a thin plastic fuse melts in them, which takes more heat then your average shower steam will give off.
