27240. (a) The producer of a gun show or event shall require that signs be posted in a readily visible location at each public entrance to the show containing, but not limited to, the following notice:
“(1) This gun show follows all federal, state, and local firearms, ammunition, and weapons laws, without exception.
(2) Any firearm carried onto the premises by any member of the public will be checked, cleared of any ammunition, and secured in a manner that prevents it from being operated, and an identification tag or sticker will be attached to the firearm before the person is allowed admittance to the show.
(3) No member of the public under the age of 18 years shall be admitted to the show unless accompanied by a parent, grandparent, or legal guardian.
(4) All firearms transfers between private parties at the show shall be conducted through a licensed dealer in accordance with applicable state and federal laws.
(5) Persons possessing firearms of ammunition at this facility shall have in their immediate possession government-issued photo identification, and display it upon request to any security officer or any peace officer, as defined in Section 830.
(6) All ammunition transfers between private parties at the show shall be conducted through a licensed dealer or ammunition vendor in accordance with applicable state and federal laws.
(7) Firearms must be handled responsibly and securely stored to prevent access by children and other unauthorized users. California has strict laws pertaining to firearms, and you may be fined or imprisoned if you fail to comply with them. Visit the internet website of the California Attorney General at https://oag.ca.gov/firearms for information on firearm laws applicable to you and how you can comply.
(8) Children may be unable to distinguish firearms from toys and may operate firearms, causing severe injury or death. If you keep a firearm within any premises under your custody or control, and a person under 18 years of age gains access to the firearm and carries it off-premises, you may be guilty of a misdemeanor, unless you stored the firearm in a locked container, or locked the firearm with a locking device.
(9) You may be guilty of a misdemeanor, including a significant fine or imprisonment, if you keep a firearm where a minor is likely to access it or if a minor obtains and improperly uses it, or carries it off of the premises to a school or school-sponsored event, unless you stored the firearm in a locked container or locked the firearm with a locking device.
(10) If you negligently store or leave a firearm within any premises under your custody or control where a person under 18 years of age is likely to access it, you may be guilty of a misdemeanor, including a significant fine, unless you stored the firearm in a locked container or locked the firearm with a locking device.
(11) Discharging firearms in poorly ventilated areas, cleaning firearms, or handling ammunition may result in exposure to lead, a substance known to cause birth defects, reproductive harm, and other serious physical injury. Have adequate ventilation when discharging or cleaning firearms or handling ammunition. Wash hands thoroughly after exposure.
(12) Federal regulations provide that if you do not take physical possession of the firearm that you are acquiring ownership of within 30 days after you complete the initial background check paperwork, then you must complete the background check process a second time in order to take physical possession of that firearm.
(13) No person shall make an application to purchase more than one handgun or semiautomatic centerfire rifle within any 30-day period and no delivery shall be made to any person who has made an application to purchase more than one handgun or semiautomatic centerfire rifle within any 30-day period.
(14) If a firearm you own or possess is lost or stolen, you must report the loss or theft to a local law enforcement agency where the loss or theft occurred within five days of the time you knew or reasonably should have known that the firearm had been lost or stolen.”
(b) The show producer shall post, in a readily visible location at each entrance to the parking lot at the show, signage that states: “The transfer of firearms or ammunition on the parking lot of this facility is a crime.”
