<strong>Sustainable</strong> <strong>Construction</strong> -<br />
Besides concrete encasement and concrete infill of hollow steel sections, there are other fire<br />
protection systems such as fire-rated boards, spray-on materials and intumescent paint to<br />
enhance the fire resistance of structural steel members.<br />

Is modification to a proprietary fire protection system allowed?<br />
Most of these fire protection systems are proprietary systems<br />
fire-tested in approved laboratories according to standards<br />
stipulated by the Relevant <strong>Authority</strong>, before they can be<br />
listed in the PLS.<br />
The fire tests are carried out on a mock-up that is built for the<br />
purpose of testing. Therefore the protection system applied<br />
at site must be similar to the set-up of the mock-up. For<br />
instance, the intumescent paint primer used at the site must<br />
be the same as the one used in the mock-up fire test.<br />
Hence, if the proprietary systems have to be modified to suit<br />
the project, the system has to be re-tested at an approved<br />
laboratory.<br />
