42. Rigging
General Rigging equipment for material handling shall be inspected prior to use on each shift and as necessary during its use to ensure that it is safe. Each day before being used, the sling and all fastenings and attachments shall be inspected for damage or defects by a competent person designated by the employer.
Riggers should keep their hands, fingers and feet clear of pinch points. Be aware of stacked material when lifting to avoid knocking it over with a swinging load. Use a designated spotter during lifting to ensure proper clearances are maintained. Check for overhead power lines before lifting a load

Rigging, 우리나라에서는 신호수(?), 양중작업을 이야기 할 수 있습니다.
우리나라에서는 아직 Rigger Certificate 제도가 없습니다.
외국의 경우, Rigger Certificate를 운영해서 Level I, II, III 등으로 등급을 나누어 두었습니다.
10톤 이하 중량물에 대해서는 Level III 가 신호수 업무를 할 수 있고… 이상의 중량물에 대해서는 그 이상의 Level를 취득한 사람만이 신호업무를 할 수 있습니다.
또한 Rigging Plan (중량물 취급작업) 역시, Rigger 의 일정 Level을 갖은 사람으로부터 인정을 받아야만, 승인된 Rigging Plan으로 인정됩니다.
그래서 대형 구조물, 기계 등의 Rigging Plan은 높은 등급의 레벨을 갖고 있는 Rigger가 작성할 수 있습니다.
