Gypsum is approximately 21 percent by weight chemically combined water which greatly contributes to its effectiveness as a fire resistive barrier. When gypsum drywall is exposed to fire, the water is slowly released as steam, effectively retarding heat transmission. Fire rated gypsum drywall is more fire resistant because it contains glass fiber reinforcement and other additives within its specially formulated gypsum core to help it hold up longer to a fire exposure. Fire  rated drywall is referred to as “Type X” and must be third-party certified by an independent testing and listing agency such as UL (Underwriters Laboratories Inc.) and ULC (Underwriters’ Laboratories of Canada) to meet the fire performance requirements prescribed in the ASTM C1396 (CAN/CSA-A82.27) Standard Specification for Gypsum Board. Types of Fire Rated Gypsum: Type X fire rated gypsum drywall that is 5/8 -inch (15.9mm) thick and installed on each side of nominal 2-inch x 4-inch (38x89mm) ...

1) What are the types of pump sets used and why in fire fighting? Jockey pump – used when there is a pressure drop. Electric pump – Main pump starts instantly in case of fire and will cutoff. Diesel pump – used in case of power shut down & Stand by Pump. 2) What is fire alarm check valve? It allows flow in one direction and prevents backward flow and with this gives signal to BMS with alarms. 3) What is FM-200 and where is it used? Heptafloropropane is colorless, liquefied compressed gas. It is stored as a liquid and dispensed into the hazard as a colorless, eclectically non-conductive vapor that is clear and does not obscure vision. It is used in communication rooms, electrical rooms, computer rooms etc.. 4) Types of detectors? Smoke, Heat & Multi detectors etc... 5) Do we use strainers in fire pumps? Why? No, we don’t use it because the water coming is portable usually only in cases where we are using river or lake water then we require strainers. Else we prefe...

General Fire Fighting Equipment Fire fighting systems and equipment vary depending on the age, size, use and type of building construction. A building may contain some or all of the following features: fire extinguishers fire hose reels fire hydrant systems automatic sprinkler systems. Fire extinguishers Fire extinguishers are provided for a 'first attack' fire fighting measure, generally undertaken by the occupants of the building before the fire service arrives. It is important that occupants are familiar with which extinguisher type to use on which fire. Most fires start as a small fire and may be extinguished if the correct type and amount of extinguishing agent is applied whilst the fire is small and controllable. The principle fire extinguisher types currently available include: Extinguishing Agent     Principle Use Water wood and paper fires - not electrical Foam flammable liquid fires - not electrical Carbon dioxide electrical fir...

Pipe Schedule Method for Firefighting Sprinkler System                                     Pipe Schedule Method for Firefighting Sprinkler System  The water demand for firefighting sprinkler systems shall be determined by either the pipe schedule method or the hydraulic calculation method, in this article we will discuss the pipe schedule method. What is pipe schedule system?! According to NFPA 13, Pipe Schedule System is defined as sprinkler system in which the pipe sizing is selected from a schedule that is determined by the occupancy classification and in which a given number of sprinklers are allowed to be supplied from specific sizes of pipe. Where can we use pipe schedule method?! New systems of 465 m2 or less. Additions or modifications to existing pipe schedule systems. Classification of occupancies according to hazard NFPA 13 classifies the occupa...

The placement of fire exit signs should never be overlooked. Not only is the effective placement of these signs critical to the safety of the people working or visiting your building, they're also required by building and fire codes to ensure those unfamiliar with a building's layout are directed to safety if a fire were ever to happen. If a fire ignites and your building starts to fill with smoke: Do you know how to get out quickly? Do you know where the closest exits are? What if your first choice for a fire exit is blocked by smoke or fire? Is there an alternate exit? Answering these questions before you encounter them will go a long way in keeping the people in your building safe! Placing fire exit signs effectively can keep the occupants safe by directing them to safety even if they're not familiar with the building's layout. Follow the Green Running Man! In 2010, the National Resource Council's building regulations group updated its model buildi...

A guide to Fire Alarm System types Contents: Conventional fire alarm systems Two-wire fire alarm systems Analogue addressable fire alarm systems Wireless fire alarm systems Aspirating smoke detection systems 1. Conventional fire alarm systems Conventional, or four-wire, fire alarm systems have been extensively used in smaller properties such as shops and restaurants for many years. Less expensive to purchase than other types of alarm system, they work by dividing the building into a number of detection zones, with the detectors and call points within each zone hardwired on dedicated circuits to the control panel. There may be multiple detectors on a single zone. A separate two-core, fire-protected cable for each alarm sounder or bell is needed because they are wired to different loops. If a detector is activated, the control panel identifies the circuit that contains the triggered device and so indicates the zone from which the fire alarm has originated, but the area ...
