| 2016-08-29 11:52:35 | THIS PLAN WAS REVIEWED AND APPROVED BY PETER LEDUC, |
| | FIRE MARSHAL, WITH THE FOLLOWING COMMENTS: |
| | |
| | PLEASE CONSIDER THE FOLLOWING AS PROVISO: |
| | |
| | THESE PROVISO COMMENTS WILL BE VERIFIED AND CONFIRMED |
| | AT THE TIME OF FIRE INSPECTION. FAILURE TO FOLLOW THESE |
| | PROVISO COMMENTS WILL RESULT IN A FAILED FIRE |
| | INSPECTION. |
| | |
| | |
| | 1) A NOTE IS INDICATED AS SAYING THAT A PRESSURE TEST |
| | IS NOT REQUIRED FOR AREAS THAT CAN NOT BE ISOLATED SUCH |
| | AS RELOCATED DROPS. |
| | |
| | THE CODE REFERNECE INDICATED 24.2.1.6 DOES NOT APPLY. |
| | |
| | THIS INSTALLATION INDICATES ADDITIONAL BRANCH LINES AND |
| | A 200PSI PRESSURE TEST IS REQUIRED. |
| | |
| | 24.2 ACCEPTANCE REQUIREMENTS. |
| | 24.2.1* HYDROSTATIC TESTS. |
| | 24.2.1.1 UNLESS PERMITTED BY 24.2.1.2 THROUGH 24.2.1.8, |
| | ALL PIPING AND ATTACHED APPURTENANCES SUBJECTED TO |
| | SYSTEM WORKING PRESSURE SHALL BE HYDROSTATICALLY TESTED |
| | AT 200 PSI (13.8 BAR) AND SHALL MAINTAIN THAT PRESSURE |
| | WITHOUT LOSS FOR 2 HOURS. |
| | 24.2.1.2 PORTIONS OF SYSTEMS NORMALLY SUBJECTED TO |
| | SYSTEM WORKING PRESSURES IN EXCESS OF 150 PSI (10.4 |
| | BAR) SHALL BE TESTED AS DESCRIBED IN 24.2.1.1, AT A |
| | PRESSURE OF 50 PSI (3.5 BAR) IN EXCESS OF SYSTEM |
| | WORKING PRESSURE. |
| | 24.2.1.4 MODIFICATIONS AFFECTING 20 OR FEWER SPRINKLERS |
| | SHALL NOT REQUIRE TESTING IN EXCESS OF SYSTEM WORKING |
| | PRESSURE. |
| | 24.2.1.5 WHERE ADDITION OR MODIFICATION IS MADE TO AN |
| | EXISTING SYSTEM AFFECTING MORE THAN 20 SPRINKLERS, THE |
| | NEW PORTION SHALL BE ISOLATED AND TESTED AT NOT LESS |
| | THAN 200 PSI (13.8 BAR) FOR 2 HOURS. |
| | 24.2.1.6 MODIFICATIONS THAT CANNOT BE ISOLATED, SUCH AS |
| | RELOCATED DROPS, SHALL NOT REQUIRE TESTING IN EXCESS OF |
| | SYSTEM WORKING PRESSURE. |
| | 24.2.1.7 LOSS SHALL BE DETERMINED BY A DROP IN GAUGE |
| | PRESSURE OR VISUAL LEAKAGE. |
| | 24.2.1.8* THE TEST PRESSURE SHALL BE READ FROM A GAUGE |
| | LOCATED AT THE LOW ELEVATION POINT OF THE SYSTEM OR |
| | PORTION BEING TESTED. THE PRESSURES IN PIPING AT HIGHER |
| | ELEVATIONS SHALL BE PERMITTED TO BE LESS THAN 200 PSI |
| | (13.8 BAR) WHEN ACCOUNTING FOR ELEVATION LOSSES. |
| | SYSTEMS OR PORTIONS OF SYSTEMS THAT CAN BE ISOLATED |
| | SHALL BE PERMITTED TO BE TESTED SEPARATELY. |
| | 24.2.1.9* ADDITIVES, CORROSIVE CHEMICALS SUCH AS SODIUM |
| | SILICATE, OR DERIVATIVES OF SODIUM SILICATE, BRINE, OR |
| | SIMILAR ACTING CHEMICALS SHALL NOT BE USED WHILE |
| | HYDROSTATICALLY TESTING SYSTEMS OR FOR STOPPING LEAKS. |
| | 24.2.1.10 PIPING BETWEEN THE EXTERIOR FIRE DEPARTMENT |
| | CONNECTION AND THE CHECK VALVE IN THE FIRE DEPARTMENT |
| | INLET PIPE SHALL BE HYDROSTATICALLY TESTED IN THE SAME |
| | MANNER AS THE BALANCE OF THE SYSTEM. AFTER REPAIR OR |
| | REPLACEMENT WORK AFFECTING THE FIRE DEPARTMENT |
| | CONNECTION, THE PIPING BETWEEN THE EXTERIOR AND THE |
| | CHECK VALVE IN THE FIRE DEPARTMENT INLET PIPE SHALL BE |
| | ISOLATED AND HYDROSTATICALLY TESTED AT 150 PSI (10.3 |
| | BAR). |
| | 24.2.1.11 WHEN SYSTEMS ARE BEING HYDROSTATICALLY |
| | TESTED, IT SHALL BE PERMITTED TO CONDUCT TEST WITH |
| | PENDENT SPRINKLERS OR PLUGS INSTALLED IN FITTINGS. ANY |
| | PLUGS SHALL BE REPLACED WITH PENDENT SPRINKLERS AFTER |
| | THE TEST IS COMPLETED. |
| | 24.2.1.12 WHEN DELUGE SYSTEMS ARE BEING HYDROSTATICALLY |
| | TESTED, PLUGS SHALL BE INSTALLED IN FITTINGS AND |
| | REPLACED WITH OPEN SPRINKLERS AFTER THE TEST IS |
| | COMPLETED, OR THE OPERATING ELEMENTS OF AUTOMATIC |
| | SPRINKLERS SHALL BE REMOVED AFTER THE TEST IS |
| | COMPLETED. |
| | 24.2.1.13 PROVISION SHALL BE MADE FOR THE PROPER |
| | DISPOSAL OF WATER USED FOR FLUSHING OR TESTING. |
