| | REVIEW COMMENTS - FIRE DEPARTMENT |
| | |
| | I AM NOT CONVINCED, BUT, REQUESTING A % DENSITY |
| | REDUCTION FOR STORAGE HEIGHTS BELOW 20 FEET (NFPA 13 |
| | SECTION 16.2.1.3.4) MIGHT BE JUSTIFIED FOR THE CEILING |
| | SLOPE OF 11.8 DEGREES (2.5/12 OR 0.21); HOWEVER, HALF |
| | THE BUILDING UTILIZED FOR STORAGE HAS A CEILING SLOPE |
| | OF 16 DEGREES (3.25/12 OR 0.27). HIGH-PILED COMBUSTIBLE |
| | STORAGE COUPLED WITH A SLOPED CEILING (PITCH EXCEEDING |
| | 2/12 OR 0.16) CAN GREATLY AFFECT THE QUANTITY AND THE |
| | LOCATIONS OF THE SPRINKLERS THAT MAY BE ACTIVATED |
| | DURING A FIRE EVENT. HIGH-PILED STORAGE WITHOUT A |
| | HORIZONTAL CEILING IS OUTSIDE THE SCOPE OF NFPA 13; |
| | THEREFORE, A PERFORMANCE-BASED ENGINEERING DESIGN IS |
| | NEEDED. IF FM DATA IS CHOSEN, THEN ALL THE REQUIREMENTS |
| | OF FM NEED TO BE FOLLOWED AND SUBMITTED. SELECTIVE |
| | REQUIREMENTS OR "CHERRY PICKING" WILL NOT BE SUPPORTED. |
| | THE ENGINEERING RESPONSE LETTER INDICATES, "FOR ROOF |
| | SLOPES GREATER THAN 10 DEGREES BUT LESS THAN 20 |
| | DEGREES, FM SUGGESTS PROTECTION UNDER SUCH SLOPED ROOFS |
| | IS ACCEPTABLE PROVIDED THAT ONE LEVEL OF IN-RACK |
| | SPRINKLERS AND STANDARD RESPONSE CEILING SPRINKLERS ARE |
| | INSTALLED;" HOWEVER, NO FM DATA SHEET SECTION IS |
| | PROVIDED FOR REFERENCE. FM DATA SHEET 2-0, SECTION |
| | 2.2.1.6 INDICATES THAT "STORAGE" SPRINKLERS ARE |
| | ACCEPTABLE UNDER SLOPED CEILINGS BETWEEN 10 AND 20 |
| | DEGREES; HOWEVER, STORAGE SPRINKLERS BY FM STANDARDS |
| | HAVE A K-FACTOR GREATER THAN 8.0 (K=8.0 CURRENTLY |
| | INSTALLED CEILING SPRINKLERS). |
| | |
| | THE PLANS INDICATE SPRINKLERS/PIPING TO BE SUPPORTED |
| | BELOW THE MEZZANINE. PROVIDE A SIGNED/SEALED LETTER |
| | WITH LOAD CALCULATION INDICATING THE MEZZANINE |
| | STRUCTURE IS CAPABLE OF SUPPORTING THE WEIGHT OF WATER |
| | FILLED PIPING PLUS 250 POUNDS APPLIED AT THE POINT OF |
| | HANGING PER NFPA 13 SECTION 9.2.1.3.1. |
| | |
| | AN INSPECTION CONDUCTED 12/29/14 REVEALED 8 (VERIFY) |
| | FLAMMABLE LIQUID STORAGE CONTAINERS (CAPACITY: 90 |
| | GALLONS EACH) LOCATED ADJACENT TO THE STORAGE |
| | MEZZANINE. |

| | ORIGINAL COMMENTS: |
| | THE PLANS INDICATE A REQUIRED DENSITY OF 0.23 |
| | GPM/SQ.FT. OVER 2500 SQ.FT. PER FIGURE 16.2.1.3.2(C) |
| | USING CURVE A; HOWEVER, CURVE A REQUIRES |
| | HIGH-TEMPERATURE CEILING SPRINKLERS. PER SPRINKLER |
| | PERMIT #12030242, THE CEILING SPRINKLERS ARE ORDINARY |
| | TEMPERATURE (155F). THE USE OF ORDINARY TEMPERATURE |
| | SPRINKLERS REQUIRES THE DESIGNER TO UTILIZE CURVE B OF |
| | FIGURE 16.2.1.3.2.(C). A DESIGN AREA OF 2500 SQ.FT. |
| | CORRESPONDS TO A DENSITY OF 0.26 GPM/SQ.FT. |
| | |
| | INDICATE WHAT MEANS/METHODS ARE IN PLACE TO LIMIT THE |
| | HIGH-PILED STORAGE TO 18.5 FEET ABOVE FINISHED FLOOR SO |
| | DENSITY CAN BE REDUCED TO 87% PER FIGURE 16.2.1.3.4.1. |
| | |
| | IN-RACK SPRINKLERS SHALL BE LOCATED AT AN INTERSECTION |
| | OF TRANSVERSE AND LONGITUDINAL FLUES WHILE NOT |
| | EXCEEDING THE MAXIMUM SPACING RULES. |
| | |
| | HAS AN INCREASED DESIGN AREA OR SKEWED OPERATING |
| | PATTERN BEEN CONSIDERED TO ACCOUNT FOR THE CEILING |
| | SLOPE EXCEEDING 2 IN 12? THE SPRINKLER SYSTEM CRITERIA |
| | SPECIFIED IN CHAPTER 12 AND CHAPTERS 14 THROUGH 20 ARE |
| | INTENDED TO APPLY TO BUILDINGS WITH CEILING SLOPES NOT |
| | EXCEEDING 2 IN 12 (16.7 PERCENT) PER NFPA 13 SECTION |
| | 12.1.2 - CEILING SLOPE. |
| | |
| | PROVIDE A SPRINKLER DETAIL OR ELEVATION SHOWING THE |
| | SPRINKLER PLACEMENT WITHIN THE RACKS. |
| | |
| | NO HYDRAULIC CALCULATIONS SUBMITTED. |
| | |
| | |
| | |
| | EMAIL STRING FROM 11/12/14: |
| | FM DATA SHEET 2-0 INDICATES, "STORAGE SPRINKLERS ARE |
| | ACCEPTABLE UNDER SLOPED CEILINGS"; HOWEVER, THE |
| | CURRENTLY INSTALLED CEILING SPRINKLERS (RELIABLE MODEL |
| | F1, K-8.0 [SIN R1722] ARE NOT APPROVED AS STORAGE |
| | SPRINKLERS PER FM BECAUSE THEY HAVE A K-FACTOR OF 8.0. |
| | PLEASE SEE BELOW... |
| | |
| | FM DATA SHEET 8-9 (STORAGE OF COMMODITIES) |
| | |
| | 2.3.3 CEILING-LEVEL STORAGE SPRINKLERS |
| | |
| | FM APPROVED SPRINKLERS FOR STORAGE OCCUPANCY HAZARDS |
| | AND OTHER SIMILAR HIGH HEAT-RELEASE TYPE FIRES ARE |
| | LISTED IN THE APPROVAL GUIDE, AN ONLINE RESOURCE OF FM |
| | APPROVALS, UNDER THE HEADING OF STORAGE SPRINKLERS |
| | (CEILING-LEVEL) OR STORAGE SPRINKLERS (IN-RACKS). THIS |
| | SECTION WILL DISCUSS RECOMMENDATIONS FOR FM APPROVED |
| | CEILING-LEVEL STORAGE SPRINKLERS. |
| | |
| | FOLLOW THE GUIDELINES IN DATA SHEET 2-0, INSTALLATION |
| | GUIDELINES FOR AUTOMATIC SPRINKLERS, FOR THE |
| | INSTALLATION OF CEILING-LEVEL STORAGE SPRINKLERS. |
| | |
| | USE ONLY FM APPROVED SPRINKLERS LISTED IN THE APPROVAL |
| | GUIDE UNDER THE HEADING OF STORAGE SPRINKLERS |
| | (CEILING-LEVEL) FOR ANY CEILING-LEVEL SPRINKLER OPTIONS |
| | IN THIS DATA SHEET. CURRENTLY, FM APPROVED |
| | CEILING-LEVEL STORAGE SPRINKLERS HAVE K-FACTOR VALUES |
| | RANGING FROM 11.2 TO 25.2. NOTE THAT THE FOLLOWING |
| | SPRINKLERS ARE NOT FM APPROVED AS CEILING-LEVEL STORAGE |
| | SPRINKLERS: K=8.0 AND SMALLER. |
