The essential elements of ﬁre protection can be classiﬁed as either passive or active ﬁre protection.
Used in conjunction with one another to provide a balanced ﬁre protection strategy in modern construction, both active and passive ﬁre protection systems are analogous to safety belts and air bags in automobiles.
Active ﬁre protection elements are designed to activate once a ﬁre starts to control growth or extinguish it.
Examples include ﬁre sprinklers or gaseous extinguishing systems, ﬁre alarms also fall into this category as they provide notiﬁcation to building occupants and emergency responders.
Passive ﬁre protection elements are designed to control ﬁre growth and spread through the erection of barriers that minimize the spread of ﬁre, smoke and hot gases. Such systems are said to compartmentalize or contain ﬁre to the point or origin thereby allowing occupants time for safe egress and ﬁreﬁghting personnel time for safe ingress to perform search and rescue.
Passive ﬁre protection systems may also enhance structural integrity.
Examples of passive ﬁre protection include ﬁre-resistive rated ﬂoors and walls, ﬁre prooﬁng materials for structural elements, ﬁre doors and ﬁre dampers.
Cementitious or wet mix fireproofing is mixed with water and pumped under pressure through hoses to a nozzle where air I introduced. The wet slurry is then broadcast of products onto structural steel surfaces. The inherent fire resistive mechanism of products in the release of water in the form of steam when exposed to elevated temperatures. These products are available in standard, medium and high density to use indoors and on building exteriors.
Intumescent fireproofing differs from cementitious and mineral fiber fireproofing in that its paint like appearance allows it to be left permanently exposed creating a dramatic architectural affect. Applied like paints and coatings with airless spray equipment, intumescent fireproofing actually burns when exposed to fire, forming a layer of char that ultimately insulates the structural steel from further temperature rise. Vendors of intumescent fireproofing who we have partnered whith include Jotun Manufacturing, Isolatke and Carboline co.
