fire suppression system. The information is arranged in the following
categories:
• Hazard Survey, Definition and Analysis
•Design for Safety
• Applications
• Total Flooding Application Systems
• Local Application Systems
• Combination Systems
•Multiple Hazard Systems
• Pressure Operated Sirens
• Extended Discharge Systems
• Agent Storage Banks
• Manifold and Pipe Network Design
• Actuation System Design
• Detection Devices, Alarm Devices and Control Panels
• Auxiliary Equipment and Systems
3-2 HAZARD SURVEY, DEFINITION AND ANALYSIS
The first step in any fire protection design project is to survey the area to be protected, define
the hazard, and analyze the information to determine the appropriate methods of detecting
and suppressing the fire. In addition, several key concepts for overall safety of the system
should be considered.
As a minimum, a hazard survey should consist of the following:
• Dimensions of the area to be protected, including interconnected spaces and duct work
that extends out of the protected space
• Locations and dimensions of non-closeable openings
• Locations, quantities, and types of likely fuels
• Locations and types of sources of ignition
• Locations and Basic Insulation Level (BIL) of non-insulated live electrical wiring
• Flow rate and wind-down time of forced ventilation that cannot be dampered or shut down
• Minimum and maximum ambient temperatures
• Type of wall construction (for enclosed spaces)
• Occupancy status
•Path of egress
• Hazardous classification (i.e., explosion hazard)
• Locations of pipe, duct work, beams, or other obstructions
