Conn. Gen. Stat. § 11-86
Sec. 11-86. Conservation and protective measures applied to property on loan. Liens. Immunity from liability.
(b) If a museum applies conservation or protective measures to any property on loan to the museum under this section, or with the agreement of the lender, unless the written loan agreement for such property provides otherwise, the museum shall acquire a lien on such property in an amount equal to the costs incurred by the museum for such conservation or protective measures taken.
(c) The museum shall not be liable for injury to or loss of any property that was on loan to the museum and for which conservation or protective measures were taken under this section, if the museum (1) had a reasonable belief at the time the conservation or protective measures were taken that such measures were necessary to protect such property or other property in the possession of the museum, or that such property was a hazard to the health and safety of the public or museum staff, and (2) exercised reasonable care in the choice and application of such conservation and protective measures.
