not ignite ammable material.
Failure of the owner/operator of the equipment to comply
with this regulation is a misdemeanor under California law
and may also be a violation of other state and/or federal
regulations, laws, ordinances, or codes. Contact your lo-
cal re marshal or forest service for specic information
about which regulations apply in your area.
