Building Egress Using Photoluminescent Markings

The use of photoluminescent material systems in buildings is gaining acceptance in North America as a valuable safety feature for users of exits and stairwells in the event of power failure and the loss of emergency lighting. This Update describes the characteristics and installation of photoluminescent markings.

Advances in Fire Suppression Systems

Fire suppression systems for the protection of buildings have evolved in response to new requirements, environmental pressures and advances in technology. This Update provides an overview of four recently developed systems, reviews research on the performance of each, and provides guidance on system selection, design and use.

Fire Performance of Fibre-Reinforced Polymer Systems Used for the Repair of Concrete Buildings

This Update reviews NRC-IRC research on the fire resistance of externally bonded, fibre-reinforced polymer (FRPs) systems used for repairing concrete building members. The research showed that FRP systems that include specially designed insulation can enable repaired or strengthened concrete members to exceed the 4-hour fire resistance requirements of building codes.

Basic Principles of Smoke Management for Atriums

Fires in atrium buildings can pose a serious threat to occupants as a result of smoke migration. This Update, intended for building designers and property managers, outlines the basic principles of smoke management in atriums that must be understood in order to enhance occupant safety.

Why Building Occupants Ignore Fire Alarms

Why do building occupants so often ignore fire alarm signals? This Update presents some reasons, supported by IRC studies and documentation of real fires.
