本発明は、石綿含有吹付け材および／または石綿含有材の除去作業エリア内部の負圧監視システムに関するものであり、特に除去作業エリア内部の適切な負圧状態がくずれたとき、除去作業エリア外部へ石綿により汚染された汚染空気や石綿粉塵が飛散して非常に危険となるので、負圧測定装置により除去作業エリア内部の負圧状態を常時測定し、作業者並びに工事関係者に負圧情報を通知し、更に、負圧が一定レベル以上になったときには、前記危険な状態を回避するようにした石綿含有吹付け材および／または石綿含有材の除去作業エリア内部の負圧監視システムに関するものである。 The present invention relates to a negative pressure monitoring system inside an asbestos-containing spray material and / or an asbestos-containing material removal work area, and particularly when an appropriate negative pressure state inside the removal work area breaks down, the outside of the removal work area Since contaminated air and asbestos dust contaminated by heavy asbestos are scattered and become extremely dangerous, the negative pressure inside the removal work area is constantly measured by a negative pressure measuring device, and negative pressure information is sent to workers and construction personnel. Further, the present invention relates to an asbestos-containing spraying material and / or a negative pressure monitoring system inside an asbestos-containing material removal work area that avoids the dangerous state when the negative pressure exceeds a certain level. It is.

石綿（アスベスト）は、その特性から多くの建物や商品に使用されてきたが、石綿を吸引した際の人体に及ぼす有害性から、現在はその使用が禁止されている。しかしながら、禁止以前に施工された建築物の解体、改修工事などの粉塵吸引の危険性や周辺環境への飛散等による健康障害の発生が大きな社会問題となっている。 Asbestos (asbestos) has been used in many buildings and products due to its characteristics, but its use is currently prohibited due to its harmful effects on the human body when it is inhaled. However, the dangers of dust suction such as dismantling and renovation of buildings constructed before the ban and the occurrence of health problems due to scattering to the surrounding environment are major social problems.

そして、従来建築物における石綿含有吹付け材および／または石綿含有材の除去作業は、該石綿含有吹付け材を吹付けた部屋、または石綿含有材を使用した構築物をビニールシート等により遮蔽して除去作業エリアを形成して、前記除去作業エリア内部を負圧集塵機により、負圧状態に保持して、該除去作業エリア内部を除去作業エリア外部に比べ負圧に保ち、石綿により汚染された汚染空気や石綿粉塵が除去作業エリア外部へ漏れるのを防いで除去作業をすると共に、除去作業エリア外部の空気をサンプリングして、顕微鏡で確認して、前記汚染空気や石綿粉塵の除去作業エリア外部への漏出を検知していた。 Then, the asbestos-containing spray material and / or the asbestos-containing material removal work in a conventional building is performed by shielding a room where the asbestos-containing spray material is sprayed or a structure using the asbestos-containing material with a vinyl sheet or the like. Contamination contaminated by asbestos by forming a removal work area, holding the inside of the removal work area in a negative pressure state by a negative pressure dust collector, keeping the inside of the removal work area at a negative pressure compared to the outside of the removal work area Prevents air and asbestos dust from leaking outside the removal work area, and removes the contaminated air and asbestos dust outside the work area by sampling the air outside the removal work area and checking with a microscope. A leak was detected.

また、石綿含有吹付け材および／または石綿含有材の除去作業に関する過去の特許文献を遡及検索したところ、下記の特許文献１が公知である。 Moreover, when the past patent document regarding the removal operation | work of asbestos containing spraying material and / or asbestos containing material was searched retrospectively, the following patent document 1 is well-known.

従来は、前記のように除去作業エリア内部を負圧状態に保持して、石綿含有吹付け材および／または石綿含有材の除去作業をしているが、石綿により汚染された汚染空気や石綿粉塵が除去作業エリア外部へ飛散するのを監視するため、単に除去作業エリア外部の空気をサンプリングして、これを顕微鏡で確認していたので、確認までに時間がかかり、速やかな対応を取ることができず、その結果、除去作業エリア外部へ石綿により汚染された汚染空気や石綿粉塵が飛散してしまい、非常に危険であるという課題があった。 Conventionally, asbestos-containing spraying material and / or asbestos-containing material is removed while maintaining the inside of the removal work area at a negative pressure as described above, but contaminated air and asbestos dust contaminated by asbestos Since the air outside the removal work area is monitored by simply sampling the air outside the removal work area and checking it with a microscope, it takes time to check and can take prompt action. As a result, contaminated air and asbestos dust contaminated with asbestos are scattered outside the removal work area, which is extremely dangerous.

また、特許文献１記載のものは、石綿除去方法に関するものであり、除去作業エリア内部を負圧集塵機により、負圧状態に保持するという記載があるが、除去作業エリア内部の負圧状態を監視する手段と共に、異常前に警報を発する手段を備えていないため、除去作業エリア内部の負圧状態が維持されなくなったときは、除去作業エリア外部へ石綿により汚染された汚染空気や石綿粉塵が飛散して非常に危険であるという課題があった。 Moreover, the thing of patent document 1 is related with the asbestos removal method, and there exists description that the inside of a removal work area is hold | maintained at a negative pressure state by a negative pressure dust collector, but the negative pressure state inside a removal work area is monitored. In addition, there is no means to issue an alarm before the abnormality, so when the negative pressure inside the removal work area is no longer maintained, contaminated air or asbestos dust contaminated with asbestos is scattered outside the removal work area. There was a problem that it was very dangerous.

本発明は、前記課題を解決すべくなされたものであって、除去作業エリア内部の負圧状態を、除去作業エリア内部、または外部に設置された負圧測定装置により測定することにより、前記除去作業エリア内・外の作業者、および工事関係者が、該除去作業エリア内部の負圧レベルが一定以上となった緊急事態を直ちに把握し、前記緊急事態に速やかに対応することができ、これにより除去作業エリア外部への石綿により汚染された汚染空気や石綿粉塵の飛散を防止することができる石綿含有吹付け材および／または石綿含有材の除去作業エリア内部の負圧監視システムを提供しようとするものである。 The present invention has been made to solve the above-mentioned problem, and the removal is performed by measuring a negative pressure state inside the removal work area with a negative pressure measuring device installed inside or outside the removal work area. Workers inside and outside the work area and those involved in the construction can immediately grasp an emergency situation in which the negative pressure level inside the removal work area has exceeded a certain level, and can respond promptly to the emergency situation. An attempt to provide an asbestos-containing spray material and / or a negative pressure monitoring system inside an asbestos-containing material that can prevent the scattering of contaminated air and asbestos dust contaminated by asbestos to the outside of the removal work area To do.
