Annulus (firestop)
{{unreferenced, date=March 2015 The annulus, or annular space, is the space between a penetrant and whatever surrounds it, such as the sides of an opening or a sleeve A sleeve ( ang, slīef, a word allied to ''slip'', cf.

Penetrant (mechanical, Electrical, Or Structural)
Penetrants, or penetrating items, are the mechanical, electrical or structural items that pass through an opening in a wall or floor, such as pipes, electrical conduits, ducting, electrical cables and cable trays, or structural steel beams and columns. When these items pierce a wall or floor assembly, they create a space between the penetrant and the surrounding structure which can become an avenue for the spread of fire between rooms or floors. Building codes require a firestop to seal the openings around penetrants.

Sleeve (construction)
{{inline, date=November 2020 In construction, a sleeve is used both by the electrical and mechanical trades to create a penetration in a solid wall, ceilling or floor. Purpose * For cables we provide wall/deck penetration sleeve to avoid any damage to cable from material shifting on deck. * Deck penetrations on offshore platform provided to avoid water/chemical dripping to lower deck in case of spillage. * Acts as toe guard. * For wall penetrations it can be a type of strengthening. * Together with packing it helps to protect from fire spread from one room to other. Materials Sleeves can be made of: * sections of steel pipe. * plastic. * sheet metal. * proprietary devices that are listed firestop components. Requirements * Sleeves must be sized such as to adequately allow the passage of the intended penetrant(s) plus enough room to permit the practical installation and mounting of the penetrants as well as adequate room for firestops. A general practice is to size the sleeve t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Passive Fire Protection
Passive fire protection (PFP) is components or systems of a building or structure that slows or impedes the spread of the effects of fire or smoke without system activation, and usually without movement. Examples of passive systems include floor-ceilings and roofs, fire doors, windows, and wall assemblies, fire-resistant coatings, and other fire and smoke control assemblies. Passive fire protection systems can include active components such as fire dampers. Main characteristics Passive fire protection systems are intended to: * Contain a fire to the compartment of fire origin * Slow a fire from spreading from the compartment of fire origin * Slow the heating of structural members * Prevent the spread of fire through intentional openings (e.g., doors, HVAC ducts) in fire rated assemblies by the use of a fire rated closure (e.g., fire door, fire damper) * Prevent the spread of fire through penetrations (e.g., holes in fire walls through which building systems such as plumbing ...
