Emergency abatement of dangerous structures.

In cases of emergency, which, in the opinion of the Building Inspector, involve imminent danger to human life or health, he shall promptly cause such building, structure or portion thereof to be made safe or removed. For this purpose he may at once enter such structure or land on which it stands or abutting land or structure with such assistance at such cost as may be necessary. He may vacate adjacent structures and protect the public by barricades or such other means as may be necessary and for this purpose may close a public or private way.
