2009 California Health and Safety Code - Section 12610-12611 :: Article 3. Insurance

12610.  Notwithstanding any of the provisions of the law which may
require a certificate of insurance as a condition for a permit to
hold a general, special, or limited public display, any person, firm,
or corporation applying for a public display license shall furnish
to the State Fire Marshal a policy of public liability and property
damage insurance, with limits, as determined by the State Fire
Marshal, which are reasonably necessary to cover possible liability
for damage to property and bodily injury or damage to persons which
may result from, or be caused by, the public display of fireworks, or
any negligence on the part of the licensee or his or her or its
agents, servants, employees, or subcontractors presenting the public
display.

12611.  The certificate of insurance shall provide all of the
following:
   (a) That the insurer will not cancel the insured's coverage
without 15 days' prior written notice to the State Fire Marshal.
   (b) That the duly licensed pyrotechnic operator required by law to
supervise and discharge the public display, acting either as an
employee of the insured or as an independent contractor and the State
of California, its officers, agents, employees, and servants are
included as additional insureds, but only insofar as any operations
under contract are concerned.
   (c) That the state shall not be responsible for any premium or
assessments on the policy.
