Description

本考案は、安全性の高い緊急用防煙マスクに関する。 The present invention relates to a highly safe emergency smokeproof mask.

資料により、火事に亡くなる人々の中に、60％以上の人は煙で亡くなり、大量の煙や有毒ガスを吸い込み、意識を失い、死に至る。 According to the materials, more than 60% of the people who die in a fire die from smoke, inhale a large amount of smoke and toxic gas, lose consciousness, and die.

火事現場の煙は様々な物質を有し、さらにＨＣＮ、ＨＳ、ＣＯなどの有毒ガスも有し、その中に一番危険なのは一酸化炭素であり、一般的な建材が燃焼されたことで発生した一酸化炭素の濃度は約2.5％であり、しかし、一酸化炭素の濃度は1.3％になる場合に、人は吸い込んだ後に、体内の赤血球は酸素運搬能を失うことで、意識を失い、死に至ることになり、故に一酸化炭素はもっとも危険なことである。 Smoke at a fire site has various substances, and also has toxic gases such as HCN, HS, and CO, and the most dangerous of them is carbon monoxide, which is generated by burning general building materials. The concentration of carbon monoxide is about 2.5%, but when the concentration of carbon monoxide is 1.3%, after a person inhales, the red blood cells in the body lose their oxygen carrying capacity and lose consciousness. It is fatal and therefore carbon monoxide is the most dangerous thing.

火事現場に最も有効な避難道具は防煙マスクであるが、旧式のマスクは確実に着用できず、着用中に可視性が悪い、厚さが不足で耐熱性が悪い、ろ過の効果が悪い、排気機能が良くないなどの欠点により、避難しにくくなる。 The most effective evacuation tool for fire scenes is smoke-proof masks, but older masks cannot be reliably worn, have poor visibility during wear, lack of thickness and poor heat resistance, poor filtration effect, It is difficult to evacuate due to drawbacks such as poor exhaust function.
