Safe Rooms and Shelters - CBR Threat Protection
Course Highlights

This online engineering PDH course describes how to add chemical, biological and radiological (CBR) protection capabilities to a shelter or safe room. It also discusses air filtration, safe room criteria, design requirements, operations and maintenance, commissioning, and training required to operate a shelter or safe room.


A CBR safe room protects its occupants from outside contaminated air by providing clean, breathable air in two ways: (1) by trapping air inside the room and minimizing the air exchange (an unventilated safe room) and (2) by passing contaminated air through a filter to purify it as it is supplied to the room (a ventilated safe room).


This 3 PDH online course is applicable to engineers, planners, architects, landscape designers, construction and operations personnel, security and law enforcement agents, as well as consultants and contractors who are interested in gaining a better understanding in CBR threat protection of safe rooms and shelters.
