Study Notes
Fire Safety and Suppression Systems in Buildings
- Fire sleeves are heat resistant silicone coated fiberglass sleeving that crush and seal off plastic pipes, preventing the passage of fire and smoke to adjacent compartments.
- Fire sleeves offer guaranteed protection against fire, smoke, and noise, withstanding continuous exposure up to 500°F and short-term exposure up to 2200°F, while also being resistant to hydraulic fluids, fuels, and lubricating oils.
- Fire collars maintain fire resistance levels by surrounding pipes and other penetrations with intumescent compounds that expand throughout the fire, preventing the passage of flames and hot gases into other compartments.
- Fire covers are designed to stop fires of luminaires in fire-rated suspended ceilings by expanding internally to fill available space with a fire-resistant, highly insulating char, reducing the chance of heat build-up and ignition of flammable materials.
- Firestop products, such as penetration sealants, fire sealants, gap fillers, intumescent sealants, and pillows, are passive fire protection components that work together to contain a fire and prevent it from spreading beyond the point of origin.
- Inert gas fire suppression systems reduce oxygen levels below 15% by displacing oxygen with Argon/Nitrogen, while synthetic gas suppression systems use a cooling mechanism to remove heat and quickly extinguish fires in under 10 seconds.
- Clean agent systems are electrically non-conductive and designed to interrupt the combustion process to extinguish fires without damaging sensitive equipment, reaching a required concentration level to suppress a fire.
- Clean agents do not leave a residue upon evaporation and are inert gas and chemical agents designed to protect data and valuable assets, posing minimal health risks to humans at low concentration levels.
- Synthetic gas systems store fluid as a liquid in pressurized cylinders with nitrogen, and automatic detection sensors trigger release when the fire is at the incipient stage, extinguishing it in mere seconds.
- Firestop products, including penetration sealants, fire sealants, gap fillers, intumescent sealants, and pillows, offer easy retrofitting of cable installations without damaging the firestop seal.
- Fire suppression systems in server rooms are waterless and use gas-based systems, known as 'clean agents,' to suppress fires, with the gas being electrically non-conductive and designed to preserve electronics while extinguishing fires.
- Fire suppression systems using CO2 pose significant health risks, while chemical and inert clean agent systems are not harmful to humans at low concentration levels, but leaving the area before the agent is released is highly recommended.
