Mitigate
p 7
Fire prevention is the elimination of all hostile fires through ____________, ____________, and _____________.
education, engineering, and enforcement
p 7
Fire prevention also involves ______________ modification that prevents or mitigates the threat from hostile fires.
behavior
p 7
Fire protection systems can be divided into two broad categories: ?
fire detection and fire suppression
p 8
- System of detection devices, wiring, and supervisory equipment used for detecting fire or products of combustion and the signaling that these elements are present.
Fire Detection System
p 8
- System designed to act directly upon the hazard to mitigate or eliminate it, not simply to detect its presence and/or initiate an alarm.
Fire Suppression System
p 8
The ________ ____________ of a fire and the signaling of an appropriate alarm remains the most significant factor in preventing large losses due to fire.
early detection
p 8
Fire detection can be either _________ or _________.
passive or active
p 8
__________ fire protection can be a part of building construction such as a concrete firewall or sprayed on structural fire protection.
Passive
p 8
This type of fire protection system requires some type of outside intervention or mechanical support such as electricity or a water supply ?
Active fire detection and suppression systems
p 8
The first fire alarm system was installed around ______. This was a municipal alarm system that used the ____________ to notify FDs of a fire.
1851 / telegraph
p 9
The first commercially successful automatic fire sprinkler was patented in ______.
1872
p 9
In _______, George Andrew Darby, an electrical engineer, patented the first heat indicator, which sounded a fire alarm when activated.
1902
p 9
This early device paved the way for today’s battery-powered smoke alarms, which were introduced in _______ by Kenneth House and Randolph Smith.
1969
p 9
In 1947, President Harry S. Truman commissioned ?
The President’s Conference on Fire Prevention
p 11
The current concept of the Three E’s of Prevention - ___________, ____________, and ____________ - came as a result of The Presidents Conference.
education, engineering, and enforcement
p 11
President Nixon convened what commission in the 1970s ?
The National Commission on Fire Prevention and Control
p 12
The National Commission on Fire Prevention and Control produced the famous report entitled ____________ ___________.
America Burning
p 12
America Burning resulted in the passage of the ?
Federal Fire Prevention and Control Act of 1974
p 12
Overview of fire protection systems:
- Five basic categories:
- Automatic fire ____________ and ________ systems
- Automatic fire ____________ systems
- Manual fire ________ systems
- Manual fire ______________ systems
- ________ control / _________ systems
- detection and alarm
- suppression
- alarm
- suppression
- Smoke / exhaust
p 12-13
- These systems are activated by smoke, high temperatures, or radiant heat and alert the occupants in the building and/or the FD to the fire. These systems do not slow the growth of the fire or reduce the amount of smoke produced.
Automatic fire detection and alarm systems
p 12
- These systems actually work to suppress the fire hazard by applying a fire-suppressing medium to the fire. There is no need for human intervention for their effectiveness. This reduces the hazard to the occupants and to the building and its contents.
Automatic fire suppression systems
p 12
- These systems require activation by individuals upon discovery of a fire.
Manual fire alarm systems
p 12
- This category includes standpipes (both vertical and horizontal), fire hoses, and fire extinguishers. These mechanisms require an individual to operate them in order to perform their function.
Manual fire suppression systems
