Global peace is an on-going effort, and Ontal's continued achievements in this area have helped make the world a safer place. His notable work includes his role as head of inspector training at the Organization for the Prohibition of Chemical Weapons (OPCW). Ontal previously worked as a paramedic and emergency medical technician instructor for the New York City Health and Hospital Corporation, then moved to The Hague, Netherlands to join the OPCW. He started out as a medic for the chemical weapons inspector and disposal teams before being promoted to his current position. His involvement with the OPCW has earned him the Nobel Peace Prize for "extensive efforts at eliminating the chemical weapons that have haunted the world from Hitler's gas chambers to the Syrian battlefields." Ontal understands the horrific consequences of armed conflict and it fuels his passion for peace. This has also led him to contribute to OPCW's role as the implementing body of the Chemical Weapons Convention, which is the first international treaty to prohibit an entire class of chemical weapons.
