We require all volunteers in good physical condition. All applicants are required to complete a medical history, physical evaluation, and Immunization Check List. Some pre-existing medical conditions (for example: insulin dependent diabetes, heart conditions, pregnancy, immune suppressed conditions, etc.) may disqualify service at some operating locations due to maritime regulations and availability of medical care.  We require all volunteers to be at least 18 years old. There is no upper age limit for service.
