actually i got a HW to write a letter to a local newspaper about road accidents and suggest some measures to avoid them.plz help !!its really urgent!!
cant be bothered to read all that - you cant possibly know what you are talking about so would suggest motorcycle training and a bike that matches your license restriction. go to your local shop and buy a bike they service. or best still stick to the more sociable, safer bus but dont disturb the driver.
The design of CO2 System shall be as inaccordance to NFPA 12., whereby you have 4 methods of design and installation : 1. Total Flooding System 2. Local Application system 3. Pre-engineered system 4. Hand-hose line system In the case maybe if you are dealing with an enclose surface eg. switchboard room you may use option 1 with deep seated design. You won't be able to directly apply to the fire, but the CO2 that realeased in this design shall act like a blanket (buoyoncy force) to segregrate the hot surface and Oxygen. Afterall, if you are desingning for Data center where you have lots of Server Rack, you cannot use option 1 as this is real expensive and not good for normally occupied area. As such, option 2 will be the best option to design the CO2 directly purge into the server cabinet upon detection of smoke and heat using smoke detector and heat detector respectively. In your example, since the room is already smoked, you may install PYROGEN Gas system to all your electrical switchboard as pyrogen gas is as small as CO2 45kg cylinder can put off 8 Swichboard cabinets. Mode of operation is using a fuse link whereby once heat detected, pyrogen gas will purge. More effective and very less cleaning needed. IM or email me if you would like to know more on how to design a proper fire fighthing system for your application effectively without buying the infra camera or so on.
One makes it easier to sit on it's face.
If you don't know, I won't give you any letters to post! .
