No person, firm or corporation shall make an opening in any street, or disturb in
any way, the surface or subsurface of any street or sidewalk, without having first
received a permit therefor from the department. Where, because of a leak in a water
or gas main, a break in an electric duct, a broken rail, or other serious accident,
the public safety requires immediate action, the work may be proceeded without previous
permit, but the permit shall be obtained as soon after the accident as possible.
