Abstract

Considering Fire Safety Issues in Underground Facilities

Safety issues are among the prime concerns in the design, construction and operation of underground facilities. The safety regulations that are implemented to manage them are generally based on regulations previously developed for open air projects.

The aims of this paper is to provide a few international examples of underground projects, and report on the way the building codes and regulations (defined as explained for open-air public buildings or high rise buildings) have been adapted to tackle specific underground issues.

Drawing on such work, along with other examples and feedback, can lead to new performance-based approaches or proposed amendments to the regulatory framework.
