720.5 Smoke Barrier Construction. Smoke barriers shall comply with Section 714 and shall be constructed and sealed to limit leakage areas exclusive of protected openings. The maximum allowable leakage area shall be the aggregate area calculated using the following leakage area ratios: 1. Walls: A/Aw = 0.00100 2. Exit enclosures: A/Aw = 0.00035 3. All other shafts: A/Aw = 0.00150 4. Floors and roofs: A/AF = 0.00050 where: A = Total leakage area, square feet.

AF = Unit floor or roof area of barrier, square feet. Aw = Unit wall area of barrier, square feet. The leakage area ratios shown do not include openings due to doors, operable windows or similar gaps. These shall be included in calculating the total leakage area.

720.5.1 Leakage Area. The total leakage area of the barrier is the product of the smoke barrier gross area multiplied by the allowable leakage area ratio, plus the area of other openings such as gaps and operable windows. Compliance shall be determined by achieving the minimum air pressure difference across the barrier with the system in the smoke control mode for mechanical smoke control systems. Passive smoke control systems tested using other approved means such as door fan testing shall be as approved by the Building Official. 720.5.2 Opening Protection. Openings in smoke barriers shall be protected by automatic-closing devices actuated by the required controls for the mechanical smoke control system.

ON-OFF and OPEN-CLOSE control actions shall have the highest priority of any control point within the building. Once issued from the fire-fighter's control panel, no automatic or manual control from any other control point within the building shall contradict the control action. Where automatic means are provided to interrupt normal, nonemergency equipment operation or produce a specific result to safeguard the building or equipment (i.e., duct freezestats, duct smoke detectors, high-temperature cutouts, temperature-actuated linkage and similar devices), such means shall be capable of being overridden by the fire-fighter's control panel. The last control action as indicated by each fire-fighter's control panel switch position shall prevail. In no case shall control actions require the smoke control system to assume more than one configuration at any one time.

Exception: Power disconnects required by the EPCOT Electrical Code.

2. Only the AUTO position of each three-position fire-fighter's control panel switch shall allow automatic or manual control action from other control points within the building. The AUTO position shall be the NORMAL, nonemergency, building control position. Where a fire-fighter's control panel is in the AUTO position, the actual status of the device (on, off, open, closed) shall continue to be indicated by the status indicator described above. When directed by an automatic signal to assume an emergency condition, the NORMAL position shall become the emergency condition for that device or group of devices within the zone. In no case shall control actions require the smoke control system to assume more than one configuration at any one time. 720.17 System Response Time. Smoke-control system activation shall be initiated immediately after receipt of an appropriate automatic or manual activation command. Smoke control systems shall activate individual components (such as dampers and fans) in the sequence necessary to prevent physical damage to the fans, dampers, ducts and other equipment. For purposes of smoke control, the fire-fighter's control panel response time shall be the same for automatic or manual smoke control action initiated from any other building control point. The total response time, including

Food that uses cooking oils of any type in the preparation or service, and that has an option for carry out orders. Fast food facilities will use a fryer of some type and size for food preparation. DELI STYLE. Food that does not use cooking oil in the preparation or service, and that has an option for carry out orders. Deli style facilities will have no fryers, and be principally cold service foods. STANDARD SERVICE. A sit down facility will include all facilities that serve food in a dining area and utilize washable cutlery and washable plates and glassware, but does not serve alcoholic beverages. FULL SERVICE. A sit-down facility includes all facilities that serve food in a dining area, utilizes washable cutlery, plates and glassware and serves any type of alcoholic beverage. 1003.3.4.3 Procedure for Determining Grease Interceptor Size: 1) Determine the peak flow to the interceptor

a) Determine the number of seats (maximum) and assume 100% use/occupancy.

b) Determine the maximum number of take-out meals served (if any)

c) Apply the flow factors to the above i) 25 gpd/seat ii) 5 gallons/take out meal (non-fast food)

iii) 2.5 gallons/take out meal (fast food) d) Apply the peak factor

i) Use 3.0 times unless documented otherwise

Peak Flow (gpd) = (# Seats X 25 + # take-out meals X (5 or 2.5») X peak factor of 3

2) Determine the type and character of the Facility and interceptor cleaning frequency a) Apply the appropriate service factors for:

i) Operating hours ii) Food service type iii) Proposed cleaning frequency iv) Seat turnover

3) Complete the calculation for the interceptor size Trap Volume = Peak flow (in gpm) x 120 minutes Detention Time x Peak Factor x Cleaning Factor x Open Hours Factor x Service Type Factor x Seat Factor.

4) Select appropriate interceptor size by rounding up to the nearest 100 gallon increment.

5) For trap volumes exceeding 5000 gallons, use multiple units operating in parallel.

a. For operating hours other than those listed, use a ratio of: actual hours/12 Size of interceptor is a function of: 1. Detention time desired in trap, usually this is a minimum of 2 hours 2. Type of drains routed through trap - sanitary drains should be piped separately 3. Water volume or flow rate generated from number of seats and/or meals served

Page 46 of 48

Basis and Rational for Formula 5 gallons per meal is used as the water volume if meals served is the design basis. 15 - 50 gallons per seat shall be used as the water volume if seats used are the design basis. A minimum of two hours of detention time (DT) in the interceptor is required at peak flow rates (>120 minutes). If the facility is a combination sit-down and take out, then a combination of these shall be used for flow estimation. The number of meals served at the sit down is allowed to be subtracted from the total meals served to calculate flow. Or the number of seats plus the maximum number of meals taken out shall be used for flow calculations

Basic formula shall be:

Trap Volume = Peak flow (in gpm) x 120 minutes Detention Time x Peak Factor x Cleaning Factor x Open Hours Factor x Service Type Factor x Seat Factor.

Flow shall be based on the number of seats or meals served or combination of both times a flow factor for each. 25 gallons per seat is the norm for this criterion, and 5 gallons per meal. However, for fast food and deli service operations, which use primarily paper and plastic cutlery and packaging a figure of 2.5 gallons per meal served shall be used for fast food and deli food style establishments. If the design criteria value used is number of seats, then a factor for the turnover ratio of the seats shall be used.

Standard and full service sit down

Peak flow = (Number of seats X 25 gpd/seat + number of take-out meals (max.) X 5 gal/meal) X Peak factor Peak factor to be 3 times unless justification can be provided to the Building Official substantiating a lesser value.

Deli/ fast food

Peak flow = (Number of seats X 25 gpd/seat + number of take-out meals (max.) X 2.5 gal/meal) X Peak factor Peak factor to be 3 times unless justification can be provided to the Building Official substantiating a lesser value.

EXAMPLES of FORMULA For example, assume a sit down restaurant that is open 12 hours per day, has 120 seats, has one hour per seat turnover and intends to clean their trap quarterly. Also assume they use 25 gallons per seat and a peaking factor of 3. All operational and facility factors would therefore be 1.0. Trap size would be:

Flow = 120 x 25 x3 = 9000 gallons per day Trap Size = 9000/1440 x 120 = 750 gallons, or the minimum size

Now let's assume we have a fast food restaurant that serves 5000 meals a day, is open 16 hours a day, has seating capacity for 40 people, turns the seats over 1/hour, and intends to clean the trap on a quarterly basis. Trap size would be:

Flow = 40 x 25 x 3 = 3000 gallons per day # meals served at sit down = 40 X16 X 1/hr = 640 plus (5000-640) x 2.5 = 10900 gallons Total flow = 13900 gallons Trap size= 13900/1440 x 120 x 1.333 = 1540 gallons or about twice the size of the smallest trap.

Now assume an extreme case, a fast food restaurant serving 15000 meals a day with 200 seats, open 20 hours per day turning over their seats every 30 minutes and intends to clean their trap quarterly. Trap size would be:

Flow = 200 x 25 x 3 = 15000 gpd # meals served at sit down = 200 X 16 x 2 = 6400 plus 15000-6400 X 2.5 = 21500 gallons Trap size = (15000 + 21500)/1440 x 120 x 1.667 = 5079 gallons If this facility only intended to clean their trap 2x1year, the size would double to 10,000 gallons

Now assume the other extreme, a walk up deli style open 8 hours per day with no seats and expecting to service its trap only annually, serving 500 meals per day on a peak day, or about one per minute. Trap size would be:

Flow = 500 x 2.5 x 3 = 3750 gpd, based on meals served only, no sit down. Trap size: 3750/1440 X 120 X 0.667 X 0.5 X 4 = 417 gallons; or a minimum tank of 750 gallons would suffice

Now assume a large full service restaurant with 500 seats, open 16 hours per day, with turnover of seats at once per hour no take out, and a cleaning frequency of quarterly. Trap size would be:

Flow = 500 x 25 x 3 = 37500 gallons Trap size = 37500/1440 X 120 X 1.33 X 1.2 X 1.0 = 4987.5 gallons or say 5000 gallons
