人均舱容是医用高压氧舱(空气加压氧舱,以下简称氧舱)舱室容积与满员治疗人数的比值。人均舱容是氧舱最重要的安全技术指标之一。如果人均舱容太小,舱内氧浓度就容易超标,从而容易引起舱内起火事故的发生。1994年,我国1年内就发生了3起因人均舱容过小、舱内氧浓度上升过高而引起的中型氧舱舱内起火恶性事故,共造成26人死亡、1人受伤,损失十分惨重。物质燃烧的三要素分别是可燃物、一定浓度的
The per capita capacity is the ratio of the volume of medical hyperbaric oxygen chamber (air-pressurized oxygen chamber, hereinafter referred to as oxygen chamber) to the full treatment of patients. Per-capita capacity is one of the most important safety specifications for oxygen tanks. If the per-capita capacity is too small, the oxygen concentration in the tank will easily exceed the standard, which will easily lead to fire accident in the cabin. In 1994, three serious fire accidents occurred in mid-sized oxygen cabin caused by too small capacity per capita and excessive increase in oxygen concentration in the country within a year. Twenty-six people were killed and one injured. The loss was very heavy. The three elements of material combustion are combustible, a certain concentration
