MAKING THE CHOICE ON PASSIVE PROTECTION

This article presents a review of the advantages and disadvantages of passive fire protection solutions that are currently available for tunnels. The most common types of fireproofing materials used in tunnels are spray coatings, such as shotcrete with lightweight filter or pre-packaged inorganic spray materials, and insulating panel boards that are attached to the tunnel surface. In order to be effective, these materials must provide sufficient internal strength, ease in constructability, durability, and resist environmental changes occurring with the tunnel. Under advantages, factors to be considered may include: application, adaptability, protection, quality control, history, design, porosity, and aesthetics. For advantages, the same factors may apply, but additional ones may include overspray, debonding, expansion joints, and structural defects. In addition to the factors mentioned, the costs involved tunnel fireproofing solutions, from installations to maintenance, need to be given full consideration.
