CIOB Bitesize: ASET vs RSET
£20.00
Overview
Overview of ASET vs RSET Bitesize Course
This interactive module can be completed in under 60 minutes, and effectively breaks down how to encourage healthy Available Safe Egress Time (ASET), well within the margins of Required Safe Egress Time (RSET).
The module is delivered online and combines practical examples, interactive activities, and knowledge checks to help learners understand how different fire safety measures support safe evacuation and encourage safe occupier behaviour.

Objectives & Assessment
Explain how Available Safe Egress Time (ASET) and Required Safe Egress Time (RSET), including the factors that influence tenability, occupant response and evacuation, work together to inform fire safety design and support the safe evacuation of occupants during a fire emergency.
