The Ministry of the Interior in cooperation with several partners has put together and updated the good practice guidelines for the lifeguard service and the rental services for different watercraft. The good practice guidelines for the services are aimed towards local governments, security companies, lifeguards, and other companies providing water-related services. The guidelines are not mandatory (they are not legally binding), they are merely recommendations that help increase the water safety level in Estonia.
