| 2016-09-19 13:30:27 | THIS PLAN WAS REVIEWED AND FAILED BY PETER LEDUC, FIRE |
| | MARSHAL, WITH THE FOLLOWING COMMENTS: |
| | |
| | 1) THE SEPARATION DISTANCES OF THE PROPOSED TRAILERS |
| | ARE NOT INDICATED AND APPEAR TO NOT MEET THE MINIMUM |
| | SEPARATION DISTANCES IN NFPA 241. THE PROPOSED |
| | CONFIGURATION IS CONSIDERED A LARGE CONSTRUCTION |
| | SUPPORT COMPLEX. FIRE SPRINKLER PROTECTION WOULD BE |
| | REQUIRED TO REDUCE THE DISTANCES BY 75%. |
| | |
| | PER NFPA 241, 4.2 TEMPORARY OFFICES AND SHEDS; |
| | |
| | TABLE 4.2.1 SEPARATION DISTANCES, FIRE SPRINKLERS ARE |
| | REQUIRED IN EACH TRAILER. |
| | 4.2.1* SEPARATION DISTANCES BETWEEN BUILDINGS UNDER |
| | CONSTRUCTION AND CONSTRUCTION-RELATED STRUCTURES, SUCH |
| | AS TEMPORARY OFFICES, TRAILERS, SHEDS, AND OTHER |
| | FACILITIES FOR THE STORAGE OF TOOLS AND MATERIALS |
| | HAVING COMBUSTIBLE CONSTRUCTION OR CONTENTS, SHALL BE |
| | IN ACCORDANCE WITH TABLE 4.2.1. |
| | |
| | 1) 20 FEET EXPOSED LENGTH SHALL BE SEPARATED FROM |
| | ADJACENT STRUCTURES BY AT LEAST 30 FEET |
| | 2) 30 FEET EXPOSED LENGTH SHALL BE SEPARATED FROM |
| | ADJACENT STRUCTURES BY AT LEAST 35 FEET |
| | 3) 40 FEET EXPOSED LENGTH SHALL BE SEPARATED FROM |
| | ADJACENT STRUCTURES BY AT LEAST 40 FEET |
| | 4) 50 FEET EXPOSED LENGTH SHALL BE SEPARATED FROM |
| | ADJACENT STRUCTURES BY AT LEAST 45 FEET |
| | 5) 60 FEET EXPOSED LENGTH SHALL BE SEPARATED FROM |
| | ADJACENT STRUCTURES BY AT LEAST 50 FEET |
| | 6) GREATER THAN 60 FEET EXPOSED LENGTH SHALL BE |
| | SEPARATED FROM ADJACENT STRUCTURES BY AT LEAST 60 FEET |
| | **A 75 PERCENT REDUCTION IN SEPARATION DISTANCES SHALL |
| | BE PERMITTED TO BE APPLIED, PROVIDED AUTOMATIC |
| | SPRINKLER PROTECTION IS USED IN THE EXPOSING STRUCTURE. |
| | |
| | NOTES: |
| | (1) WHERE THE SEPARATION DISTANCE BETWEEN TEMPORARY |
| | STRUCTURES IS LESS THAN THE MINIMUM SEPARATION |
| | DISTANCE, THEN THE EXPOSING WALL LENGTH SHALL BE |
| | CONSIDERED TO BE THE SUM OF THE INDIVIDUAL EXPOSING |
| | WALL LENGTHS OF THE TEMPORARY STRUCTURES. |
| | (2) A 75 PERCENT REDUCTION IN SEPARATION DISTANCES |
| | SHALL BE PERMITTED TO BE APPLIED, PROVIDED AUTOMATIC |
| | SPRINKLER PROTECTION IS USED IN THE EXPOSING STRUCTURE. |
| | (3) THE SEPARATION DISTANCES APPLY TO SINGLE-LEVEL |
| | STRUCTURES ONLY. THIS TABLE DOES NOT APPLY TO |
| | MULTILEVEL, UNSPRINKLERED STRUCTURES. A LEVEL, WHERE |
| | APPLYING THIS TABLE, IS 3600 MM (144 IN.). |
| | |
| | 4.2.2* DETACHMENT BETWEEN TEMPORARY STRUCTURES, |
| | ADEQUATE TEMPORARY FIXED FIRE PROTECTION SYSTEMS, AND |
| | PORTABLE EQUIPMENT SHALL BE PROVIDED AS REQUIRED BY THE |
| | AUTHORITY HAVING JURISDICTION. |
| | |
| | A.4.2.2 WHERE LOCATED 9M(30 FT) OR MORE FROM THE |
| | STRUCTURE AND CONSTRUCTED OF COMBUSTIBLE MATERIALS, IT |
| | IS RECOMMENDED THAT TEMPORARY SUPPORT BUILDINGS BE |
| | DIVIDED INTO SMALL, DETACHED UNITS TO MINIMIZE FIRE |
| | LOSS. LARGE CONSTRUCTION SUPPORT |
| | COMPLEXES SHOULD BE PROTECTED WITH ADEQUATE FIRE |
| | PROTECTION (E.G., AUTOMATIC SPRINKLERS, YARD HYDRANTS, |
| | HOSE, AND EXTINGUISHERS) AS REQUIRED BY THE AUTHORITY |
| | HAVING JURISDICTION. |
| | |
| | |
| | PLEASE PROVIDE FOR THE MINIMUM SPEARATION DISTANCES OR |
| | PROVIDE FIRE SPRINKLER PROTECTION IN EACH TRAILER. |
