John Gerrish

Spending 10+ years with hands-on, in-depth training and handling of dangerous goods / hazmat as a C-130 Loadmaster in the U.S. Air Force, laid the foundation for John to start his own packing company, specializing in dangerous goods shipments. A degree in musical education provided the teaching skills for instructing others in the intricacies of preparing, offering, accepting, and rejecting hazmat shipments. 

A Vietnam-era military background and the real-world situations encountered operating JGA’s affiliate packing company, Airpack, for 25+ years has provided the basis for John’s passion and desire to educate others on shipping dangerous goods. His primary goal in instruction is to assist the student in understanding the regulations while maintaining safety when preparing or offering hazmat into transportation. John is an IATA Certified Training Instructor, Department of Defense Training Instructor, and former Educational Director for the National Institute of Packaging, Handling and Logistics Engineers (NIPHLE), and former President of the Baltimore Washington Cargo Association (BWACA).
