The International Transport Forum (ITF) launched recently a Draft Discussion Paper titled “Overcoming Obstacles to Implementing Safety Management Systems”, prepared for the Roundtable on Safety Management Systems (March 23-24, 2017, Paris), authored by Jouni Lappalainen. The purpose of this paper is to examine the obstacles to implementing safety management systems and to discuss solutions for overcoming those obstacles in the four modes of transport: aviation, maritime, rail and road. These four transport modes can be considered to represent safety critical industries.  pdf5
