territory of a town outside of villages shall be an officer designated  for

  2.   Permits  for  public  displays.   Notwithstanding  the provisions of
section 270.00, the permit authority of a state park,  county  park,  city,
village  or  town  may  upon application in writing, grant a permit for the
public display of fireworks by municipalities, fair associations, amusement
parks  or  organizations  of  individuals.  The application for such permit
shall set forth:
  (a)   The  name  of  the body sponsoring the display and the names of the
persons actually to be in charge of the firing of the display.
  (b)  The date and time of day at which the display is to be held.
  (c)  The exact location planned for the display.
  (d)   The age, experience and physical characteristics of the persons who
are to do the actual discharging of the fireworks.
  (e)  The number and kind of fireworks to be discharged.
  (f)  The manner and place of storage of such fireworks prior to the
display.
  (g)   A diagram of the grounds on which the display is to be held showing
the point at which the fireworks are to be discharged, the location of  all
buildings,  highways  and  other  lines  of communication, the lines behind
which the audience will be restrained and the location of all nearby trees,
telegraph or telephone lines or other overhead obstructions.
  (h)  Such other information as the permit authority may deem necessary to
protect persons or property.
  3.   Applications  for  permits.   All  applications  for permits for the
public display of fireworks shall be made at least five days in advance  of
the  date  of  the display and the permit shall contain provisions that the
actual point at which the fireworks are to be fired shall be at  least  two
hundred  feet  from  the  nearest  permanent  building,  public  highway or
railroad or other means of travel and at least fifty feet from the  nearest
above   ground   telephone  or  telegraph  line,  tree  or  other  overhead
obstruction, that the audience at such display shall be  restrained  behind
lines  at  least  one  hundred  and  fifty feet from the point at which the
fireworks are discharged and only persons in active charge of  the  display
shall  be  allowed  inside  these  lines,  that  all  fireworks that fire a
projectile shall be so set up that the projectile will go into the  air  as
nearby as possible in a vertical direction, unless such fireworks are to be
fired from the shore of a lake or other large body of water, when they  may
be  directed  in such manner that the falling residue from the deflagration
will fall into such lake or body of water, that any fireworks  that  remain
unfired  after the display is concluded shall be immediately disposed of in
a way safe  for  the  particular  type  of  fireworks  remaining,  that  no
fireworks  display  shall  be  held during any wind storm in which the wind
reaches a velocity of more than thirty miles per hour, that all the persons
in  actual charge of firing the fireworks shall be over the age of eighteen
years, competent and physically fit for the task, that there  shall  be  at
least  two  such operators constantly on duty during the discharge and that
at least two sodaacid or other approved type fire extinguishers of at least
two and one-half gallons capacity each shall be kept at as widely separated
points as possible within the actual area of the display.  The  legislative
body  of  a  state park, county park, city, village or town may provide for
approval of such permit by the head of the police  or  fire  department  or
both  where  there  are  such  departments.   No  permit granted and issued
hereunder shall  be  transferable.   After  such  permit  shall  have  been
granted,  sales,  possession,  use  and  distribution of fireworks for such
display shall be lawful solely therefor.
  4.   Bonds.  Before granting and issuing a permit for a public display of
fireworks as  herein  provided,  the  permit  authority  shall  require  an
adequate  bond  from  the  applicant  therefor,  unless it is a state park,
county park, city, village or town, or from the person to whom  a  contract
for  such  display  shall  be  awarded,  in a sum to be fixed by the permit
authority, which, however, shall not be less than  five  thousand  dollars,
conditioned for the payment of all damages, which may be caused to a person
or persons or to property, by  reason  of  the  display  so  permitted  and
arising  from any acts of the permittee, his agents, employees, contractors
or subcontractors.  Such bond shall run to the  state  park,  county  park,
city,  village  or town in which the permit is granted and issued and shall
be for the use and benefit of any person or persons or any owner or  owners
of  any  property so injured or damaged, and such person or persons or such
owner or owners are hereby authorized to maintain an action thereon,  which
right  of action also shall accrue to the heirs, executors, administrators,
successors or assigns of such person or persons or such  owner  or  owners.
The  permit  authority  may  accept,  in  lieu  of  such bond, an indemnity
insurance  policy  with  liability  coverage   and   indemnity   protection
equivalent  to  the terms and conditions upon which such bond is predicated
and for the purposes herein provided.
  5.   Local  ordinances  superseded.   All  local ordinances regulating or
prohibiting  the  display  of  fireworks  are  hereby  superseded  by   the
provisions  of  this  section.   Every city, town or village shall have the
power to enact ordinances or local laws regulating or prohibiting the  use,
or  the  storage,  transportation  or  sale  for  use  of  fireworks in the
preparation for or in connection with television broadcasts.
