| | |
| | 1) PLEASE REFER TO NFPA 37-2010 ANNEX EXPLANATORY |
| | MATERIAL, SECTIONS A.8.2.3.1 AND A.11.4.2.3, IT APPEARS |
| | THAT THE INTENTION IS TO HAVE THE EXHAUST FROM BOTH THE |
| | GENERATOR ENGINE AND FROM THE GENERATOR ROOM TERMINATE |
| | OUTSIDE OF THE BUILDING AND NOT UNDERNEATH THE |
| | STRUCTURE. |
| | |
| | A.8.2.3.1: EXHAUST SYSTEMS SHOULD NOT TERMINATE UNDER |
| | STRUCTURES (INCLUDING LOADING PLATFORMS) OR WHERE |
| | EXHAUST GAS ENTRAINMENT INTO VENTILATION INTAKES MIGHT |
| | OCCUR. |
| | |
| | A.11.4.2.3: MECHANICAL VENTILATION SYSTEMS CAN CONSIST |
| | OF THE NORMAL VENTILATION SYSTEM FOR THE ROOM OR |
| | ENCLOSURE OR A DEDICATED PURGE SYSTEM. EXHAUST AIR |
| | SHOULD DISCHARGE OUTSIDE THE STRUCTURE, AWAY FROM |
| | OPERABLE WINDOWS AND OUTSIDE AIR INTAKES. IN LOCATING |
| | THE EXHAUST AIR DISCHARGE, CONSIDERATION SHOULD BE |
| | GIVEN TO BOTH THE ENGINE ENCLOSURE AND NEARBY |
| | STRUCTURES. |
| | CHAPTER 15, "AIRFLOW AROUND BUILDINGS," OF THE ASHRAE |
| | 1997 HANDBOOK-FUNDAMENTALS CAN BE CONSULTED FOR |
| | GUIDELINES ONEXHAUST AIR STACK HEIGHT AND DISTANCE FROM |
| | OTHER STRUCTURES, AS WELL AS AIR INTAKES NEEDED TO |
| | PROVIDE ADEQUATE DILUTION AND TO AVOID DETRIMENTAL |
| | EFFECTS OF DOWNDRAFTS. |
| | |
| | A) REFER TO SECTIONS 501.3 AND 501.3.1(4) FBC-14 |
| | MECHANICAL WHICH REQUIRE THE EXHAUST SYSTEMS NOT TO |
| | TERMINATE WHERE THEY COULD CAUSE A NUISANCE, OR BE |
| | READILY DRAWN INTO A VENTILATING SYSTEM, AND MUST BE 3' |
| | FROM EXTERIOR WALLS AND ROOFS. |
| | |
| | 2) THE SCREENING FOR THE GENERATOR ROOM EXHAUST DUCT |
| | SHALL BE CORROSION RESISTANT WITH OPENINGS NOT LESS |
| | THAN 1/4" AND NOT LARGER THAN 1/2". THE 1" WELDED |
| | STAINLESS MEXH SPECIFIED ON THE PLANS DOES NOT MEET THE |
| | CODE. |
| | |
| | 3) PLEASE PROVIDE WIND LOAD ENGINEERING FOR |
| | INSTALLATION OF THE GEF-1 AND EXHAUST DUCTWORK- SECTION |
| | 301.15. |
