Firestop

What is firestop?

  • Passive fire protection is an integral part of fire protection engineering.

  • Fire protection design consists of detection, suppression and containment.

  • Passive fire protection means the containment by firestopping system.

  • Smoke & toxic gas is leading killer in fire. (75% of all fire deaths are caused by smoke inhalation).

  • Sprinklers suppress flames, NOT smoke & gasses.
