06. Can a Chief Safety Officer or SMS Executive also be responsible for security in a transit system?

Yes, a Chief Safety Officer or SMS Executive also can be responsible for security in their transit system. In rail transit systems, Chief Safety Officers cannot have additional operational and maintenance responsibilities, they must be dedicated to ensuring safety within the system as a full-time responsibility. Rail transit agencies may petition FTA to allow its Chief Safety Officer to serve multiple roles given administrative and financial hardships with having a single, dedicated, and full-time Chief Safety Officer.

03. How does SMS integrate with system safety?

SMS improves on the SSPP framework by integrating and harmonizing the various elements of a safety plan so that they work together to manage safety risks throughout all aspects of a transit agency’s operations. SMS provides structure and accountability to supply management with ongoing information about safety risks concerning an agency’s operations. SMS supports management decisions to prioritize actions and allocate resources to resolve identified safety concerns or reduce safety risk to an acceptable level.

02. How does SMS differ from system safety?

The key difference between SMS and system safety is how safety is managed under each approach. FTA’s PTASP rule requires transit operators to manage their safety risks through the implementation of SMS. SMS is a top-down, data-driven management system which involves the continuous collection and analysis of information that helps a transit operator become proactive about how it addresses safety risks. In contrast, system safety—a common transit industry approach to safety—is an engineering discipline that incorporates safety into a system during its design and construction.
