Appropriate cleaning and disinfection of building materials are proven methods for reducing and controlling infections.
A smoke production index and flame spread index is then derived from the measurements that are taken.
A room fire can be divided into various phases. Products used in performance spaces and other special applications may require more detailed specification than provided by this classification.
