Question one
An artificially generated smoke differs from a real smoke from the fire in that the artificial smoke has high velocity. Its pressure is measurable at in terms of few inches WG or some few kilopascals. The smoke is pressurized or passed through a pressured compartment or blowers and extended heat exchangers nozzles. Natural smoke from the fire on the other side has a low pressure of movement.
Question two
Concept Smoke generator is the machine or the device that generates the artificial smoke by heating the smoke chemical above its boiling point turning it into vapor. The concept generator is an active device. The heat exchanger is an active device as well. Smoke detectors in the room are passive devices that detect the smoke.
Question three
A beam smoke detector is used to detect the smoke in the large rooms as well as a fire detector in buildings while a spot smoke detector detects only smoke in relatively small rooms. A spot smoke detector is uneconomical, and it is restricted by the height of the building. Also, a beam smoke detector
Question four
The purpose of this smoke panel is to indicate the positive and negative status of the smoke control system at different regions. It allows the firemen to control the flow of air into the building. The panel has switches for various fans and dampers in the building. The LED indicators show the position of the fans and dampers.
Question five
The fire protection equipment includes fire extinguishers, smoke alarms, dorgard and fire door retainers, exit fire equipment, CO detectors, emergency lighting and signs, and fire alarm systems. These equipment are not controlled by the smoke because smoke cloud spreads all over the building. If they detect smoke, they will indicate the smoke which is not as critical as outbreak fire detection.
Question six
In conducting a Life Safety Analysis, tenability criteria must be established such as Carbon monoxide concentration of 6000 ppm or a temperature of 140 °F where we know the effects of those individual combustion products on the body. Tenability criteria is a smoke hazard management routine to enable the occupants of the building to move to a safer place before evacuation routes become untenable as a result of the smoke.
Question seven
Requirements for children of particular ages in the egress include the capability of walking fast in the room to get evacuated in the shortest time possible, indicative of variability for example loss of hearing that affects the response capability. Sex is a requirement in the evacuation: boys tend to be bolder to evacuation procedures than girls; physical fitness and capability must be considered as weak children might suffer in the evacuation compared to the physically challenged children.
Question eight
The difference between Intelligibility and Audibility is that audibility is the level of sound power compared to the ambient noise levels whereas Intelligibility is the ability of the listener to understand noise with response to noise from a fire siren/alarm. A device will affect the egress time of the occupants if the right message is conveyed to the inhabitants.
Question nine
All Occupants Immediately Decide to Exit When Hearing an Alarm. A study done indicates that most people do not evacuate abruptly after the fire alarm goes on in times of fire outbreak (Tubbs, Jeffrey, and Brian, 233). People wait to finish what they are doing. Others wait to undertake other activities before deciding to evacuate. This myth is therefore not valid as egress addresses.
