• Should security overrule safety?

• Should safety overrule security?

• Should both compromise?

• OR, can objectives of both be met?

• Early planning and collaboration

• Respect for each other’s principles

• To sensitize you to the

• Probability of interruption is best measure of Physical Protection Systems (PPS) effectiveness

• How much risk is acceptable versus cost of reducing that risk.

• Goal of risk assessment is not to spend as much as possible, but rather to help decision-makers spend available money most effectively to reduce risk.

R I S K M A N A G E M E N T F O R SAFETY

• Fire prevention to reduce probability

• Reducing ignition sources

• Fire protection to reduce consequences

• Early detection, sprinklers, compartmentation, smoke control

Use the same analysis!Risk = Probability x Consequence

• Same approach!

• We are both in the business of risk management

• Problem: If untenable conditions are reached before evacuation

• Compare time to untenable conditions with time to evacuate

• ASET/RSET Analysis


19

• ASET: Available Safe Egress Time

• RSET: Required Safe Egress Time

19

Objective: RSET ≤ ASET

• i.e. Time to evacuate ≤ Time to untenable conditions

• Adversary timeline is based on adversary’s tasks

• Response timeline is based on detection and response times

• Timely detection occurs at a sensing point IF the Physical

Protection Systems (PPS) response time is less than

remaining adversary task time

• Life safety RSET ≤ ASET has a strong correlation to the security response time line

• Both have timelines to respond to the “adversary”

• Solutions buy time for intervention

• Analysis, Evaluation and Testing of PPS elements

• Adversary paths and Adversary Sequence Diagrams (ASDs)

• Critical path is the path with the lowest probability of interruption



27


• The PPS is a complex arrangement of detection, delay and response elements.

• Review and update PPS periodically to:

• Take account of advances in protection hardware and systems

• Changing circumstances (i.e. layout changes, new functions or assets at a facility)

• Anticipate the credible worst case scenarios

• Deterministic analysis

• Planning: what do to in case of a fire?

• Occupants respond better to emergencies when:

• They are prepared

• They are familiar with surroundings

• Led by knowledgeable trained staff

…of both security and safety in the built environment.

We can work towards an integrated approach to security and safety in the built environment
