천장 상부에 올라가서 덕트 보온작업은 사람이 떨어질 수 있습니다. 작업발판 상태를 확인하고 확인하고 점검해야 합니다. 덕트/전기/소방 관련된 작업으로 천장(텍스) 위로 올라가서 작업하는 경우에 추락사고 점검을 필히하여야 합니다.
약 10년 전에 4m 높이 천장 위에서 케링(행거)에 의존하여 임시발판(합판 등)을 놓고 작업하던 중, 잘못 밟아서 추락하는 사고가 있습니다.
눈에 보이지 않다보니 더욱 위험하고, 사다리가 안닿는 높은 천장은 특히나 더 위험하니, 현장 조건에 맞도록 적절한 작업대 확보가 필요합니다.
현장에 납품되는 대형 덕트를 보온작업하는 공장에서 있었던 일 입니다. 공장에 세워두었던 덕트가 넘어지며 그 아래에 있던 근로자 위로 쓰러져 상해사고가 발생되었습니다. 플랜트 현장은 대형 덕트 및 HVAC 자재/기계를 이용하여 작업하니 밀폐공간작업 등도 같이 확인해야 할 것 입니다.
위 내용은 HVAC 부분을 다루었지만 HVAC 의 범위가 공조시스템으로 넓다보니 국한적이지 않은, 복합적인 작업으로 이해하여 주시기 바랍니다.
감사합니다.
