Table 1 Problems to consider in the method

Flexibility so that a large variety of protection objectives can be addressed

M

Large number of stakeholders

M

Stakeholders with a high exposure to antagonistic attacks (exposing less exposed stakeholders)

A

The initiating event might impair both passive and active fire safety features

A

Common-cause failure due to large number of protection systems and increased probability for common-cause failure due to larger initiating event.

A/M

A lot of different functions provided, however not all are of main concern and the most important ones need to be determined

M

The fire severity, fire development or growth rate might be higher than what is usually designed for (including what protection systems are designed for)

A/M

Support systems that are important for functions and fire safety features

A/M

Domino effects (e.g. fire following explosion)

A

Location of fire (critical locations, e.g. sensitive areas, smaller fires where fire protection do not achieve the protection objective)

A/M

Security features (surveillance, access control, easy access areas etc.)

A

How to determine relevant antagonistic attacks (both large scale and small as arson)

A

First priority should be life safety then the core function of the building

A/M

Core functions of the building and relevant stakeholders need to be determined

A/M

Areas or functions needed to handle an ongoing event need to be analyzed

A/M

Guidance on firm and measurable protection objectives

M

Flexibility to take into account emergency management plans and action plans

M

Higher tendency for failure of protection system due to maintenance issues

M

Passive protection might be inadequate due to maintenance problems

M

External exposures such as a bomb threated vehicle brought into the building for evacuation

A

Method needs to be simple enough to identify and determine scenarios to be analyzed during a site visit
