Protecting People and Property

Electricity can be a common cause of fire, especially if the electrical circuits are overloaded. If a computer or outlet catches on fire, you should use a class C extinguisher, which is a carbon dioxide (CO₂)-based extinguisher. You should not attempt to extinguish an electrical fire with water, because water conducts electricity. If the fire is small, you may use a portable extinguisher to put the fire out immediately, but you should never put yourself in harm’s way. If the fire begins to get out of control, everyone should move to a safe area and call 911 for help immediately. Some server rooms have built-in fire suppression systems that release CO₂or halon when a fire alarm occurs. Halon is a toxic compressed gas, in liquid form, that chemically disrupts a combustion reaction. A CO₂system is designed to flood the room with carbon dioxide in order to remove all oxygen from the room, thereby killing the fire. People who are working in a server room and hear the fire alarm sounding must immediately vacate the area and get to a safe location. This is a life-threatening situation, both because of the fire and because of the potentially lethal nature of the fire-suppression systems.

電力可能是引起火災的常見原因，尤其是在電路過載的情況下。如果計算機或插座著火，則應使用C類滅火器，它是一種基於二氧化碳（CO2）的滅火器。您不應嘗試用水滅火，因為水可以導電。如果火很小，則可以使用便攜式滅火器將火立即撲滅，但絕對不要傷害自己。如果火勢開始失控，所有人應移至安全區域並立即撥打911尋求幫助。一些服務器機房具有內置的滅火系統，在發生火警時會釋放二氧化碳或哈龍。哈龍是有毒的壓縮氣體，呈液態，化學上會破壞燃燒反應。為了將房間中的所有氧氣清除，CO2系統被設計為向房間中註入二氧化碳，從而殺死火災。在服務器機房工作並聽到火警警報的人員必須立即離開該區域並到達安全位置。由於起火以及滅火系統的潛在致命特性，這是威脅生命的情況。
