Okla. Stat. tit. 11, § 11-23-105: Ambulance service - Liability insurance - Employee

benefits.

A. The governing body of any municipality or county may

contract for ambulance service with the state or any of its agencies

or any other municipality, county, person, firm, or corporation or

combination thereof subject to such terms and conditions as may be

agreed upon between the parties or in accordance with the

requirements of the Interlocal Cooperation Act. Such contracts, if

with a person, firm, or corporation, shall provide for the carrying

of liability insurance in a sum of not less than the risk of

liability of the municipality pursuant to the provisions of Section

154 of Title 51 of the Oklahoma Statutes.

B. Any employee of a municipality, county, or public trust,

engaging in ambulance or emergency service provided by the employer

shall be entitled to all benefits of any pension fund or insurance

benefits to which such employee might otherwise be entitled. If the

employee of any city, town, county, or public trust performs

ambulance or emergency service in his off-duty hours in addition to

such employee's principal employment, the time spent in such

additional duty shall not be counted toward the person's pension and

the compensation received shall not be used to calculate the pension

that person may receive at some future time.
