Mitigating the threat of terrorist attacks

The following are links to the FEMA (Federal Emergency Management Agency) documents:

Mitigating the threat of terrorist attacks against high occupancy buildings is a challenging task.

Chapter 1: ASSET VALUE, THREAT/HAZARD, VULNERABILITY, AND RISK
This chapter presents several methodologies for architects and engineers to quantify risk and to identify the most effective mitigation measures to achieve a desired level of protection against terrorist attacks at an acceptable cost.

Chapter 2: SITE AND LAYOUT DESIGN GUIDANCE
This chapter discusses site-level considerations for development. The intent of this guidance is to provide concepts for integrating land use planning, landscape architecture (vegetation, landforms, and water), site planning, and other strategies to mitigate the design basis threats as identified via the risk assessment.

Chapter 3: BUILDING DESIGN GUIDANCE
This chapter addresses explosive blast and CBR concerns from terrorist attacks, highlighting mitigation measures that may be applied to building elements, including architectural, structural, and building envelope systems.

Chapter 4: EXPLOSIVE BLAST    
This chapter discusses blast effects, building damage, injuries, levels of protection, stand-off distance, and predicting blast effects.

Chapter 5: CHEMICAL, BIOLOGICAL, AND RADIOLOGICAL MEASURES    
This chapter is based on guidance from the CDC/NIOSH and the DoD and presents protective measures and actions to safeguard the occupants of a building from CBR threats.

Chapter 6: SAFE ROOMS WITHIN SCHOOLS
This chapter is intended as a standalone description of the concept of safe rooms within schools that will resist CBR and blast threats and to provide school board members and decision-makers with the basic components of a protective system.
