For a flight over open sea, it is mandatory that each passenger is equipped with personal protective equipment (PPE). Before entering a contract with HeliService, companies select the individual components of the PPE required for their guests. HeliService works with all major suppliers of survival suits and life jackets. From a pool of the intended suits and vests, adjusted to the respective size of the guests, the appropriate protective equipment is handed over. The handling staff takes care of pre- and post-processing of the suits. After 5 years, the suits are returned to the manufacturer and major maintenance is performed
