Image FireDamper.png thumb right European fire damper with interior fire resisting board Fire dampers are passive fire protection products used in heating, ventilation, and air conditioning HVAC ducts to prevent the spread of fire inside the ductwork through fire resistance rating fire resistance rated walls and floors. Fire Smoke dampers are similar to Fire Dampers in fire resistance rating, and also prevent the spread of smoke inside the ducts. When a rise in temperature occurs, the fire damper closes, usually activated by a thermal element which melts at temperatures higher than ambient but low enough to indicate the presence of a fire, allowing springs to close the damper blades. Fire dampers can also close following receipt of an electrical signal from a fire alarm system utilizing detectors remote from the damper, indicating the sensing of heat or smoke in the building occupied spaces or in the HVAC duct system. Regulations and fire test regimes vary from one country to another, which can result in different designs and applications.

Unreferenced date November 2008 A fish tape also known as a draw wire or draw tape is a tool used by electrician s to route new wiring through walls and electrical conduit . Made of a narrow band of spring steel , by careful manipulation, the tape can be guided through confined spaces such as wall cavities. The goal is to push toward an area where guide string has been dropped inside the confined space and to pull it through, so the guide string can then be used to pull through various types of wiring, such as phone wire, network cables or speaker wire. Fish tape is designed to pull through guide string only. Using it to directly pull the target wire can damage or warp the fish tape. Design Fish tapes are usually stored coiled on a plastic reel. Because of this, they have a natural curvature and it is this curvature that allows them to be guided. By manipulating the reel, the end of the tape can be directed slightly. The tape is rigid enough that it can then be pushed in the direction in which it is pointing. In this way it can be easily guided through an empty wall cavity. Thermal insulation , firestop s, pipe material pipe s, Duct HVAC HVAC duct s, electrical conduit s, and other obstructions make use of a fish tape more challenging. The tape can be made from many different materials including steel , fiberglass , and nylon . The tape usually has a special end ranging from a hook or loop to a specialized fastener device to allow the user to attach the tape to the cable before pulling. Double use Occasionally, two fish tapes are used from opposite ends of the wall. Because they each have a hooked end, one fish tape is capable of catching the other, and the one tape can then be pulled back, carrying the second tape out with it. Electricians sometimes attach a Battery electricity battery and a doorbell or buzzer to two fish tapes so that when the ends of the tapes make contact within the wall, the bell rings.

A sealant may be viscous material that has little or no flow characteristics and stay where they are applied or thin and runny so as to allow it to penetrate the substrate by means of capillary reaction. Anaerobic acrylic sealants generally referred to as impregnants are the most desirable as they are required to cure in the absence of air, unlike surface sealants that require air as part of the cure mechanisum that changes state to become solid, once applied, and is used to prevent the penetration of air , gas , noise , dust , fire , smoke or liquid from one location through a barrier into another. Typically, sealants are used to close small openings that are difficult to shut with other materials, such as concrete , drywall , etc. Desirable properties of sealants include insolubility, corrosion resistance, and adhesion . Uses of sealants vary widely and sealants are used in many industries, for example, construction , automotive and aerospace industries. The main difference between adhesive s and sealants is that sealants typically have lower strength and higher elongation than do adhesives. Since the main objective of a sealant is to seal assemblies and joints, sealants need to have sufficient adhesion to the substrates and resistance to environmental conditions to remain bonded over the required life of the assembly. When sealants are used between substrates having different thermal coefficients of expansion or differing elongation under stress, they need to have adequate flexibility and elongation. Sealants generally contain inert filler material and are usually formulated with an elastomer to give the required flexibility and elongation ... sealants Epoxy sealants Extruded sealants Fibrin glue Fibrin sealant s Firestop sealants Floor ... more details

Image Texaco nanticoke conduit galore.jpg thumb right Electrical conduit and Bus bar bus duct in a building at Texaco Nanticoke refinery in Nanticoke, Ontario , 1980s. An electrical conduit is an electrical piping system used for protection and routing of electrical wiring . Electrical conduit may be made of metal , plastic , fiber , or fired clay . Flexible conduit is available for special purposes. Conduit is generally installed by electrician s at the site of installation of electrical equipment. Its use, form, and installation details are often specified by wiring regulations, such as the US National Electrical Code NEC or other national or local code. The term conduit is commonly used by electricians to describe any system that contains electrical conductors, but the term has a more restrictive definition when used in wiring regulations. Some early electric lighting installations made use of existing gas pipe to gas light fixtures which had been converted to electric lamps. Since this technique provided very good mechanical protection for interior wiring, it was extended to all types of interior wiring and by the early 20th century purpose built couplings and fittings were manufactured for electrical use.

A grease duct is a duct HVAC duct that is specifically designed to vent Vegetable fats and oils grease laden vapor s from commercial cooking equipment such as stove s, pizza oven s, deep fryer s and wok s to the outside of a building or mobile food preparation trailer. Grease ducts are regulated both in terms of their construction and maintenance, forming part of the building s passive fire protection system . Even the cleaning schedule is typically dictated by the fire code and evidence of compliance must be kept on file by the owner. Special hazard gallery Image Hood1.jpg Kitchen exhaust hood interior view, before and after cleaning. Image Glen spray.jpg Rooftop fan on top of grease duct being cleaned in order to remove congealed grease. Image Daphines.jpg Top view of kitchen exhaust fan assembly on top of a grease duct before and after cleaning. Image Bucket.jpg Bucket of kitchen exhaust grease after removal from commercial restaurant grease duct. gallery The grease laden vapors are hot, to begin with. As the vapours cool down, the grease settles on colder items. It is thus important for occupational safety and health as well as compliance with local fire codes to vent such vapours outside the kitchen and outside the building where the kitchen is located. Grease, of course, is not only slippery, but also highly flammable. In fact, it qualifies as a hydrocarbon due to its inherent chemistry . Regardless of what State of matter state it is in, vapour, liquid or solid, it ignites easily and burns very rapidly, necessitating special provisions to accomplish a fire resistance rating based on an internal grease fire as well as an external fire. Special provisions also include the necessity for proof that any adjacent firestop must be compatible with the grease duct system. Requirements In North America, grease ducts must be in compliance with National Fire Protection Association NFPA 96 as well as the local building code s and fire codes.
