To determine the occupant load for the woodworking shop, we use the standard occupant load factor provided in NFPA 101, Life Safety Code. For an industrial occupancy like a woodworking shop, the typical occupant load factor is 100 square feet per person. The shop is 750 square feet (69.7 square meters), so dividing the total area by 100 square feet per person gives an occupant load of 7.5, which rounds down to 7 people.

NFPA 13, Standard for the Installation of Sprinkler Systems, provides the minimum requirements for the design and installation of sprinkler systems in buildings. NFPA 24, Standard for the Installation of Private Fire Service Mains and Their Appurtenances, addresses the installation of underground fire service mains that supply fire protection systems. Together, these documents provide comprehensive guidance for the installation and maintenance of sprinkler systems as described on plan sheet F0.1.

The symbol in question represents a check valve. A check valve is used in a fire protection system to prevent the backflow of water, ensuring that water flows in only one direction through the pipes. Symbols for fire protection components like check valves are standardized in NFPA codes and are critical for understanding the layout and functionality of fire suppression systems.

According to NFPA 1, Fire Code, fire hydrants should be located within 20 feet (6.1 meters) of a fire department access road. This distance ensures that fire hydrants are easily accessible to firefighters and their equipment during an emergency, facilitating a quick and efficient response. The proximity of hydrants to access roads is critical to the success of fire suppression activities.

According to NFPA 101, Life Safety Code, conference rooms that are used for meetings with less than 50 people are typically classified under the "Business" occupancy classification (NFPA 101, Chapter 6). This is because such small meetings are considered part of the normal operations of a business environment, and thus, the rooms are not considered "Assembly" occupancy, which requires a larger number of people (usually 50 or more).

New manual fire alarm boxes must be installed within 60 inches (1,524 mm) from the door, according to NFPA 72, National Fire Alarm and Signaling Code. This placement ensures that the alarm is easily accessible and visible for occupants as they exit, facilitating prompt alarm activation in case of fire or emergency.

Information pertaining to seismic loads would be found in the structural plans. These plans contain details about the building's framework and its ability to resist seismic forces. The structural plans include calculations and specifications that ensure the building's integrity under seismic stress, following relevant codes such as the International Building Code (IBC) and NFPA 5000.

The duration of the fire flow for a building of this size and construction type is determined by referencing the fire flow requirements outlined in NFPA 1, Fire Code. For a building of 150,000 ft² (13,935 m²) of Type II (III) construction, the required duration for the fire flow is typically 3 hours to ensure adequate water supply for firefighting efforts.

The maximum hose-lay distance from a fire apparatus to any portion of a boat stored outside is 200 feet (61 meters). This distance ensures that firefighting hoses can reach all areas of the boat storage facility while maintaining adequate water pressure and flow for effective fire suppression.

To determine the residual pressure available at a flow of 1,000 gpm (3,785 Lpm), locate the 1,000 gpm point on the horizontal axis of the water supply graph and trace vertically to intersect the residual pressure curve. Then, read the corresponding pressure value on the vertical axis. Based on the exhibit provided, the residual pressure available at 1,000 gpm flow is approximately 42 psi (2.9 bar).
