The fire and rescue services are only required to carry out interventions that are directly related to their public service missions as defined in article L. 1852-2 If they have carried out interventions that are not directly related to the exercise of their missions, they may ask the beneficiaries to contribute to the costs, under the conditions determined by deliberation of the municipal council or the deliberative body of the public establishment of inter-communal cooperation competent in fire and rescue matters. Interventions carried out by the fire and rescue services at the request of the medical control centre of centre 15, when the latter determines that private medical transporters are not available, and which do not fall within the scope of article L. 1852-2, are covered financially by the health establishments where the emergency medical assistance service is based. The conditions of this assumption of responsibility are set out in an agreement between the municipalities or public establishments for inter-municipal cooperation with responsibility for fire and rescue services and the hospital where the emergency medical assistance service is based.
