ORYX®, INTELLIGENT SOLUTIONS TO PROTECT PEOPLE AND PROPERTY

In the event of a building fire, human lives are at risk, goods are lost and the building and its systems can no longer be used.

Passive fire protection offers a series of preventive measures to ensure a building can withstand a fire for a certain period of time.

 

Three objectives of passive fire protection:

1. To prevent or limit the further spread of fire, smoke and heat

2. To retain the stability of the building and the structure for as long as possible

3. To guarantee safe escape routes for those inside the burning building

 

Four passive fire protection criteria:

  • STABILITY (R)

A building element exposed to fire and a mechanical load must sustain its support function. The structure should not collapse or bend out of shape because of the heat.

  • FLASH DENSITY (E)

When exposed to fire, a separating construction element must not show any holes or cracks allowing flames or hot gases to escape. The thermal radiation also has to meet certain requirements.

  • THERMAL INSULATION (I)

This criterion determines a construction element’s ability to keep the rising temperature on the other side of the heat source within the prescribed limits to minimise the risk of ignition.

  • SMOKE RESISTANCE (S)

A fire resistant separator has to contain smoke as well as fire. Smoke resistance is determined in a smoke leakage test at room temperature and at an elevated combustion gas temperature.
