Standard for Installation of Fire Safety Devices based on Use and Occupancy Article 42
Water source equipped under Article 41 shall be connected to pressurization and driving device in accordance with any clause of the following:1.Gravity tank shall comply with the following provisions:(1)There shall be nilometer, drainpipe, overflow discharging pipe, feedwater pipe, and inlet.(2)The necessary drop height of water tank shall be more than the value computed using the formula below:Necessary drop height = water head loss by fire hose friction + water head loss by matching pipe friction + 25 (Unit: m)H = h1 + h2 + 25m2.Pressure tank shall comply with the following provisions:(1)There shall be pressure gauge, nilometer, drainpipe, feedwater pipe, air supply pipe, air compressor, and inlet.(2)The air in a water tank shall be more than 1/3 of the capacity of the tank, and the pressure over the necessary pressure of using fire hydrant at the highest point of the building to maintain the prescribed discharging water pressure. Automatic pressurization shall be made when the pressure and liquid level inside the tank lower down. Air compressor and pressurizing pump shall be connected to emergency power source.(3)The necessary pressure of water tank for Type I fire hydrant shall be more than the value computed using the formula below:Necessary pressure = water head loss by fire hose friction + water head loss by matching pipe friction + drop height + 2.5 (Unit: kgf/cm2)P = P1 + P2 + P3 + 2.5kgf/cm23.Fire pump shall comply with the following provisions:(1)Water output of fire pump shall be more than 400 L/min each fire hydrant. However, if the total number of fire hydrants exceeds 2, the 2 shall be used as the total number.(2)The total pumping head of fire pump shall be more than the value computed using the following formula:Total pumping head = water head loss by fire hose friction + water head loss by matching pipe friction + drop height + 25 (Unit: m)H = h1 + h2 + h3 + 25m(3)The pumps shall be used dedicatedly. However, they may be used together with other fire extinguishing equipments if this has no harmful effect on the performance of the equipments.(4)They shall be connected to emergency power source.Provisions of 37.2(1)~(3) and 37.2(5) shall apply to the above-mentioned pressurization and driving device except gravity tanks, and effective decompression measures shall be taken when the discharging pressure of outdoor fire hydrant aimer exceeds 6kgf/cm2 or 0.6Mpa.
中文原文 各類場所消防安全設備設置標準第42條
依前條設置之水源,應連結加壓送水裝置,並依下列各款擇一設置:
一、重力水箱,應符合下列規定:
(一)有水位計、排水管、溢水用排水管、補給水管及人孔之裝置。
(二)水箱必要落差在下列計算值以上:必要落差=消防水帶摩擦損失水頭+配管摩擦損失水頭+25(計算單位:公尺)H=h1+h2+25m二、壓力水箱,應符合下列規定:
(一)有壓力表、水位計、排水管、補給水管、給氣管、空氣壓縮機及人孔之裝置。
(二)水箱內空氣占水箱容積之三分之一以上,壓力在使用建築物最高處之消防栓維持規定放水水壓所需壓力以上。
當水箱內壓力及液面減低時,能自動補充加壓。
空氣壓縮機及加壓幫浦與緊急電源相連接。
(三)水箱必要壓力在下列計算值以上:必要壓力=消防水帶摩擦損失水頭+配管摩擦損失水頭+落差+2.5(計算單位:公斤/平方公分)P=P1+P2+P3+2.5kgf/cm2三、消防幫浦,應符合下列規定:
(一)幫浦出水量,一支消防栓在每分鐘四百公升以上。
但全部消防栓數量超過二支時,以二支計算之。
(二)幫浦全揚程在下列計算值以上:幫浦全揚程=消防水帶摩擦損失水頭+配管摩擦損失水頭+落差+25(計算單位:公尺)H=h1+h2+h3+25m(三)應為專用。
但與其他滅火設備並用,無妨礙各設備之性能時,不在此限。
(四)連接緊急電源。
前項加壓送水裝置除採重力水箱外,準用第三十七條第二項第一款至第三款、第五款規定,室外消防栓瞄子放水壓力超過每平方公分六公斤或0.6Mpa時,應採取有效之減壓措施。
