  2. Pre-Movement Behaviour and Time • Pre-MovementBehaviour encompasses all actions taken between the initial recognition of a fire cue and actual escape movement. • Pre-Movement Time is the time taken between initial response to a fire cue and the decision to move towards an escape route.

  3. ASET/RSET • Within a Performance Based Design the ASET/RSET concept is practiced to determine whether a design is safe and provides adequate escape time or not. • ASET – Available Safe Egress Time. • RSET – Required Safe Egress Time. • When ASET>RSET, the design is considered safe.

  4. The ASET/RSET concept is considered by some to be flawed as: • Takes no account of variations in capabilities & physical condition of an individual. • It assumes that a person will move robotically to the best exit. • It also ignores the wide variety of fire scenarios which can drastically change both RSET and ASET within the same building. • A Comparable Margin of Safety between two different strategies has been suggested.

  5. Health Sector Evacuations • Individuals in the health sector are often dependant on the actions and instructions of staff. • It is difficult to predict which injuries/capabilities will present the greatest difficulty to staff during an evacuation.

  6. Evaluation Process • Questionnaires • to evaluate and analyze the difference in behaviour and emotions between Evacuation Drills and an Actual Evacuations. • Interviews with staff • compile a schedule of methods used to evacuate during a fire and compare these with best practice; • to evaluate recommendations from staff members with regards to what they feel works during an actual evacuation. • Using historical research • to evaluate the effects of smoke, CO & HCN on movement and evaluate the effects of different quantities produced from different burning matter under flaming and smoldering conditions.

  7. Using a test site • to analyze the fire scenario, actual evacuation data, drill data and time scales to evaluate how they compare with published material. • Using raw data • To evaluate whether ASET/RSET or Comparative Margin of Safety would have provided a more effective evacuation for staff and patients alike.

  8. Progress & Future Work • Progress • This work has been under-investigation for approximately 2 months; • The initial questionnaires have been created & reviewed. • Negotiations are on-going with target hospitals and the HSE. • To be completed • Final questionnaire(s) to be distributed; • Evacuations to be carried out and or historical evacuations analysed; • Interviews to be scheduled; • Data to be analyzed and conclusions drawn.
